Oh wow, a supercharger, it must really kick butt! I'm sure you have a long list of national championship winners on your website that are using your products, I just can't find that list...
anyone else notice how they didn't let the engine rev out without the blower on? if these worked why don't we see them on other 2 stroke applications like bikes, karts, snow mobile's? cause they don't
Hayden Harter who gives a shit ...their are turbo 2 stroke and 4 stroke atvs snow mobiles jet skis and whatever else...just shut the fuck up if u don't know what your talking about ....and retain a little bit of dignity
Marc Unger Your grammar should be a crime. Go find us a production model 2 stroke ANYTHING with a turbo. Only exception I can think of are newer ski doos. Other than that, it's not really done out of the factory. Do you wanna know why? Because jackasses like you would fucking slaughter yourselves with that much power. A 2 stroke 450 on a dirt bike with a turbo? Good luck keeping the front wheel on the ground.
the "supercharger" kit made of cheap as hell looking, cast aluminum? yet, costs TWICE as much as buying a brand new high output 32cc engine =/ please explain
Kingsize001100 it's not a roots type supercharger...it's an impeller type...ever look inside a turbo ? Granted...this thing is only spinning maybe 36-40,000 rpm at most, wheras a true turbo will spin at well over 100,000 rpm. These small single cylinder motors require very little air and that large impeller (large for anything 20-50 cc) moves more then enough air to make a pound or two of boost.
A blower is mounted to the front of an engine like a Paxton or vortex and a supercharger is mounted directly to the intake like a Whipple twin screw. Hope that clarifies it for you.
This is where arguing with people who don't know what they're talking about, is pointless. They think if it's not bolted to the manifold, it's not a supercharger. *sigh*. If it is NOT driven by the exhaust gas being forced across a Turbine wheel, and is driven via shaft, gear, chain, or belt. It's a supercharger.
And to add to that, a "turbo" is an exhaust driven turbine supercharger, supercharger is a broad term encompassing anything that "supercharges" the intake pressure.
The smoke clearly shows that they were tuned differently, that'll make a huge difference by itself. The internals of the SC are super cheesy looking. I'd say it's a cute novelty thing, but buying a performance engine is probably a much better deal than strapping this to a stocker.

thiagov6123 all internal combustion engines will show a drastic reduction in hp when pushed past a given rpm. That is why you try to gear your vehicle to keep revs where the power is at.
Obviously a lot of you guys don't live in snowy areas. They turbo and supercharge and put sleds on nos all the time. Especially the extreme mountain climbers. As for leaning it out yep it does but then you tune your carb or get a bigger carb to take advantage of the extra air.

You keep saying stock, but at the beginning you said it's been ported. Now my question is... does the fact that it's ported with a bigger carb benefit the supercharger performance more than it does with just a carb? This should've been done with everything stock but the exhaust.
Interesting, theoretically all 2strokes are supercharged the piston underside is a reciprocating air pump. But it sucks the air in at less than 0psig so if you pressurize the intake you could get more combustion air into the cylinder. I have never seen this done before but I guess it works.
That’s a pretty decent bump, shame though that the belts break left and right, then it’s replaced about half a tank if ran hard, maybe a tank or so if your easy on it, they need a v pulley and a harder belt, something made from like radiator hose material, rubber with rope reinforcement, or even a clogged police system
does work slightly your running super lean at idle to equalize top end with added air so slow take offs supercharger or turbo you need fuel injection and fuel maps to adjust the fuel curve during boost
Bob, I have a couple questions; first, isn't the the pressurized air coming in as the piston is going up on the compression stroke, and therefore you will have an overpressured crankcase dampening the piston during the ignition, at least until it moves below the roof of the transfers and the pressure pushes out the exhaust? Second, wouldn't you need a specially tuned pipe, since you have a change in the gasses leaving the exhaust port? it seems like the timing to bounce back and push the escaping air/fuel inside would be different. I was surprised you guys don't have pipes tuned for your superchargers. I might be interested in a 49cc version if you ever make one.
the pipe will accommodate any amount of exhaust and work, although a perfectly tuned pipe is definitely better...also the piston is slowed down, but not as much as it's helped downward by the harder combustion. If it weren't pressurizing due to the piston, he might see 50 percent increase
Thanks for the answer, I don't understand your last sentence though. Are you saying the supercharger would make a 50% increase except for the pressurizing?
Johnny Vorschilde yes, most likely they would be 50 percent rather than 30, but the piston compressing the fuel-air charge dampens it a bit. Assuming it works at all lol
Do you make this to fit a 78mm clutch on a gp460 engine running a had 223 carb I want to put it on a goped I’m sure I wouldn’t be the only one interested
***** Not when you consider power to weight ratios. yes 1 horse power for 300 bucks would be ridiculous for a real car but considering power to weight, that 1 horsepower for a hpi 5sc would be like 100 horsepower in a 2900 pound car.
Red Long This test is completely useless... In a real car we don't test HP out in the Crank because its worthless and completely useless.. ANY ENGINE with no load can gain shit tons of HP out of the most stupid modification shit even changing the filter can affect your HP that is why we do a Dyno at the WHEELS because it takes into consideration drivetrain loss and total weight of the car.. Unless this is done in a BAJA and Dyno the wheels they cant prove they gained shit... Its like buying a brand new spanking Mustang Shelby GT500 and then realize ford just specd out the Crank HP and in fact your supposedly "500HP" car only has +/-427whp a rather different number you see.. If you put that into perspective this S/C can only be adding .20HP at most and that isn't worth the 275bucks price tag.. You could probably gain more than that with just higher octane fuel.. And well "Adding" its a wrong word since S/C don't work on 2 Strokes to begin with.
31% gain in power divided by $ 275.00, is it worth it ?. Will this extra HP be usable to an average RC Joe ? Have you tried these engines running at sustained engine speed of 17,500 RPM, then you will see the difference. You have not indicated the engine temperature before getting the data and other atmospheric conditions. Just my insights....
pinoyeh you'd obviously go to a taller gear set and try to keep the rpm's where the peak power is (11,000-12,500 or so) rpm does. Ot equate to horsepower. As you can see, the power rapidly falls off after 13,700 so why you'd continue to rev it higher is a mystery to me.
The supercharger comes after the carb. Therefore an adjustment is not needed^^ it can help, but only a very little bit at max power, when the carb exceeds its usual airflow range
ok, i just found it weird, because if you tune a normal 2 stroke bike engine, then you HAVE to re-jet it, or it will run too hot and destroy the cylinder and piston...
do you do these superchargers for a marine .90 glow engine ( 15cc). i have a sc91 , so i am wondering what could the SC 91 reach without any engine mods and the addition of your supercharger..? at present the motor is around 2 bhp
I wanna see you do this test with like the weight of a person like if someone was riding a goped it has resistance i wanna see you dyno that and if its an improvement then well talk!
So amusing, the graph is shit, really, this is a complete joke, they let off the throttle and the line continues to go to the right, the bottom is RPM and apparently the rpm's still gain when you let off... All this system does is flood the engine with fuel and air and spilling loads more out through the exhaust.
+joshua arnott the graph is there to show potential customers of the 'power increase' which is complete bull, they are trying to sell a product fraudulantly.
You can make 2 stroke engine work with boost. only thing is you just CANT make it without modifications to carb and other parts. Allso if you "un boost" boosted 2 stroke it wont work without modifications.
OK, found the dyno vid. I would have like to have seen the fuel curved optimized on the base motor. If it was set up rich and the blower caused it to go lean it might account for as much as 20% of the increase. And not familiar with inertia dyno, automotive dyno measures torque, torque is what does the work, hp is just a computation based on torque and rpm. If they haven't spent several hundred hours on the dyno ans shredded a pile of motors its still backyard amateur time.
What engine was it tested on , as it can't work on our engines ,you need an exhaust valve system an inlet valve system , crank case induction not barrel induction (like ours ) the engine would be so modified that's it no longer an engine that would resemble a Baja motor , it can be done but only on special motor , some snow mobiles have them fitted but arnt a 2stroke in the common sence of what a 2stroker is ...?????
ExplitPlayer Yeah, I know. I'm always expecting each sentence to end with an "...in the world" with a deep, Mortal Combat "Finish Him" voice, for extra 'coolness' ;)
Yeah iy runs lean. And just makes the piston loose compression quick. I had one wasnt happy. But yeah it looks sweet installed lol. Now planning on getting a SC for my baja, but i dont know if its the same as a nitro engine. Since this one has its own ignition so running lean wont be a problem. But im more in if its going to gain hp.
how about you dyno a nitro engine? Also, the data input can be modified on a dyno run. IE, Ambient Air temperature, air pressure, and humidity. There's also a HUGE low end lag, one I wouldn't say it's worth it u less you ran a higher rpm clutch.
Is it worth getting or not? I'm looking at one for my savage k5.9, just to say it has one, but if it doesn't improve the performance, or drastically reduces the life of the engine, I won't be getting one
Hey Bob could I ask you a question buddy the supercharger is awesome man now the question is you have a two speed and a 3 speed transmission what is the biggest difference I know the other gear is that for speed and do you have any videos on that I want to build me a 5 B and I was thinking of getting either the two speed or 3 speed transmission I'm disabled in a wheelchair a lot of my friends do speed runs with 18 110th cars and I want to do something different with a 1 fifth scale build it up if any help would be appreciated Bob thank you very much been watching your videos for quite some time sorry I haven't subscribed until now I think you are awesome man and all your videos are great brother thank you very much you're good friend Roy
For superchargers driven by the crankshaft of the engine, it does not matter if the compressor is upstream or downstream of the throttle body. For a turbocharger where the compressor RPM isn't directly tied to the speed of the engine, however, the compressor should be upstream of the throttle plate.
Oliver Österlind on a setup like this, you have to put the carb upstream of the blower as the carb is acting as it's own fuel pump and requires crankcase pulses to actuate the diaphram in said pump.
As you can see the super charger is more inconsistent then stock imo it's not worth it if you want power gains get a bigger motor or port the intake and exaust get a bigger carb and bore it out
I def agree that they let off early on the non blown motor but the blown motor after. They let off the graph is still goin up because the inertia wheel is spinning the highest right before letting off.
Let me explain things to you people. A supercharger uses engine power to create power. It's parasitic power. In the end there is something connected physically to the engine that spins something else to create boost. Further more, any boost over atmospheric pressure is a gain. As long as the air fuel ratios are proper. That means this is real and it works. That is all.
You can't produce meaningful boost in an engine where the exhaust and intake ports are open at the same time, which is the case with all piston ported two stroke engines such as this one. Your BEST case scenario is you just push excess fuel/air/oil mix out the exhaust port. Any pressure gained from the supercharger is vented to atmosphere the instant the intake ports open, as the exhaust port opens first and closes last. If you want to boost an engine you need to be able to force more A/F mix into the cylinder than will naturally fill it when it's N/A. And you can't do that in a piston ported two stroke.
Maybe learn how a two stroke engine works and how that would negate using a supercharger or turbocharger. I love the conviction you spew your bullshit with, it’s kinda funny.
Something is out-of-whack with this video. The chart is wildly out of sync with the test. The L-R direction (X-axis) in the chart shows low-high engine RPM while the Y-axis shows HP output.... so, why does the RPM continuue to climb while the video clearly shows the engine revving then slowing? In my experience, most dyno tests need to be run over the course of at least a full minute to map power output over both engine speed and engine load changes. How do you "dyno" a motor without a dynamic load!?
+Grant Arnold its just the animation for the graph being out of synch with the audio of the video if you expect a real time readout [which it is not], but you can clearly see the the throttle is wide open the entire time the engine tone is ascending
+joshua arnott ... okay, that does make sense. the chart is the output of the test (not in sync with the video/audio) and it's basically charting the wattage at the flywheel as the motor revs to redline. the power increases are pretty amazing, in that case!
Dynamometers utilize a generator as a brake in how they're wired they provide resistance to the engine and by mathematical calculation in the software produce hp and torque readings. Same for motorcycle, atv, and auto dynos. I used to own one myself. You also have a delay from the signal through software to screen as well the video being synced. A couple milliseconds makes a difference but meaningless in the scheme of things. I'd say this is a pretty accurate depiction of their product. Yet in comparison to car Superchargers it would be considered very low quality but for an Rc car it's pretty rockin.
sadly supercharging only works with valved 2 stroke engines , so i call BS on this one : the graph is sh*t , because the rpm still rise when the throttle is clearly shut , so no actual information can be taken from it. the dyno would be nice , if you were to show it showing nubers , which you didnt , you put in a picture of a pc screen , so yes , BS
Turbo and supercharged 2 strokes has been a thing for decades, and does work. He'll diesel 2 strokes have to have a turbo or supercharger to run. Ski-do snow mobiles have turbo 2 strokes in them as well.
@@TheAmericanUhate Yes, of course supercharging 2-strokes is a thing, but only on 2-strokes with exhaust valves. the Diesel 2-strokes that youre talking about have inlet and exhaust valves and dont use the crankcase for pushing the gas exchange in the zylinders , they use a turbo or supercharger for that. theyre basically 4-strokes where youve put the inlet and exhaust in the same place, and thats inbetween the compression and power stroke at the lower deadspot. ive never had a look at ski-do snow mobiles, but eather theire diesels (like i explained above) or theyll have a rotary exhaust (and most likely also intake) valve making it possible to be charged. on a regular 2-stroke (like all 2-stroke model engines ive come across) charging would only have negative effects. you would be pressurising the crankcase, hindering the piston from pushing into it on powerstroke and when the gas exchange happens the over pressure would push straight to the exhaust port (which is open at the same time as the inlet port, most often even longer than the inlet) and because of fluid dynamics not even exchange the entire volume of the zylinder. theres a good reason why 2-stroke technology went away from a high pressure gas exchange to a low pressure slow flowing gas exchange using the tuned exhaust pipe
@@drache444444 At least they have the carburetor in the right place this time, unlike their older nitro engine kits! lol I asked them years ago how they could set it up as a "blow through" system, without the supposed "boost pressure" blowing the fuel right back through the needle valve and back into the fuel tank.... I never got a response. Can't imagine why... haha
hello cool guys. the first engine is ported.. the second one is not ported..... ported means more duration, a bigger exhaust port. when you file the port bigger the power in low rpm is gone away... my ears hear an engine without power in the bottom end. You always need some power in bootom cross motor power you want. not puch maxi effect or vespa ciaou the super charger must take away a lot of power when it's not working at low rpm. also because the transmission is not geared down but geared up. my experience learns me always gear down from crankshaft when you try to gear up..... the engine dont like it especialy two stroke's they need to run free groetjes uit nederland
Wrong! There are plenty of turbocharged (and some supercharged) 2 stroke engines ... i worked at a snowmobile dealership and we fabricated MANY turbo kits on 2 strokes ... all with massive gains. Tested with a water brake dyno.
Shoddy "dyno" Snake oil. I've tossed lots of customers "power adders" because they are just jewelry on tiny displacement engines. We always recommend carb, crank mods and juicing that work opposed to bling that removes power.
I would spend my money on a bigger displacement engine with the same foot print. Match a good tuned pipe. Like an OBR setup. An engine with this gear boosting power is just asking for 1/2 the lifespan. why bother.
Will proof is in the application. I bash with a Rampage and a 32cc engine. My buddy and I bought ours at the same time and when ever we drag raced they were equal. I put this charger on mine and it has much better acceleration at mid range and better top end than his. In 100 feet my truck is 10 to 15 lengths ahead of his every time we try. Is it 31% better, NO. Is it worth the money I would say YES if you like cool things to play with.
That is true, but your engines have no where close to the torque value. HP can be found with RPM's, which is why your 29,000 rpm .25 can see such high output numbers to begin with. Indy car engines could be thought of as example. They are extremely fast reving and make huge HP numbers with such a tiny stroke, but if you put that engine in your typical heavy framed grocery get'r, you wouldn't get two feet before you burned out your clutch or stalled the engine from lack of torque to get moving.
i like the idea of a turbo or super charge, but the idea it being on a rubber belt plus no way to oil the the turbo an due to the weight of the fan, an belt drive i dont beleave this would work , it prob would for a short time , i just dont think the belt is keeping up with the turn of the crank it slipping like crazy , an no way the chart is real
It is oiled by the intake charge being pressurized and containing oiled fuel...also the fan wouldn't weigh that much, especially since car superchargers are powered by soft rubber belts
+Strixx I'm not stating they don't. but let me just say this, legends such as Scott Finlay and Trevor Simpson are only just getting to the 8 HP mark with both reeds and PP.
+Strixx oh and OBR dyno test with many different pipes but I think you'll find that there preferred company is VRC and along with being the most successful with 90% of "there" engines is the VRC pro pipe.
Trevo Simpson has been building these LONG BEFORE they were put into RC cars.. AND HAS WAY MORE EXPERIENCE than these fools. I know Trevor personally, he use to build all my motors when I raced GoPeds.. And yes, he has made 10 HP motors.. Maybe not G23-G28 s..
All I can say is that I run an OBR G340 Reed Valve Stroker motor in my Vekta.5 and that thing hauls ass. On all of OBR's Full Mod and Competition Engines they send a Dyno Sheet with their motor. I am very happy with OBR along with Turtle Racing, DDM, and Bartalone Racing. For $550 for a built engine that is tuned for 110 octane and has lasted me over 25 tanks of gas without 1 issue, I am happy. They also build custom 2 cylinder 57cc twin engines that put out around 20hp. Now I know there are other companies that build motors and do fine work. I am just happy with OBR. I have bought 8 engines over the last 8 years from them and love their work. OBR is probably the number 1 engine builder for 5th scale RC vehicles to my knowledge. My whole point was that a putting a Supercharger on a stock engine is costly and inefficient compared to buying a built motor to begin with. Now maybe putting one on a built motor may benefit some.
@@KalLanPIDT no he's actually smart enough to see that this is bullshit, meanwhile you apparently believe this bullshit so you're the one who should go back to school
You don't need valves to compress air. You just need restriction. If your compressor (supercharger) can push more air into the crankcase than can leave, then you get higher air density. It's not that complicated.
Oh wow, a supercharger, it must really kick butt! I'm sure you have a long list of national championship winners on your website that are using your products, I just can't find that list...
The percentage gain here is insane

It's difficult to tell if you let off the throttle too soon on both runs though... Still call BS on this.
You keep saying stock, but at the beginning you said it's been ported. Now my question is... does the fact that it's ported with a bigger carb benefit the supercharger performance more than it does with just a carb? This should've been done with everything stock but the exhaust.
Why does the dyno have a bigger pully on the bottom. shouldn't you have it 1:1 so the rpm is correct.
Interesting, theoretically all 2strokes are supercharged the piston underside is a reciprocating air pump. But it sucks the air in at less than 0psig so if you pressurize the intake you could get more combustion air into the cylinder. I have never seen this done before but I guess it works.
Yes, they can be used on any application using a standard 54mm clutch and CY or Zenoah style engine.
That’s a pretty decent bump, shame though that the belts break left and right, then it’s replaced about half a tank if ran hard, maybe a tank or so if your easy on it, they need a v pulley and a harder belt, something made from like radiator hose material, rubber with rope reinforcement, or even a clogged police system
Why didn’t you change the pulley size and run it with more boost to see what you would get?
does work slightly your running super lean at idle to equalize top end with added air so slow take offs supercharger or turbo you need fuel injection and fuel maps to adjust the fuel curve during boost
i mean rich at idle my bad
Its not about the size of lump its rpm it kicks out
Do these work on RC boat motors I have a Quick Draw 35CC would it work on that please comment back thank you very much for this video
Should I make any modifications first before adding supercharger?
Bob, I have a couple questions; first, isn't the the pressurized air coming in as the piston is going up on the compression stroke, and therefore you will have an overpressured crankcase dampening the piston during the ignition, at least until it moves below the roof of the transfers and the pressure pushes out the exhaust?

Not even half aa annoying as 90% of americans saying "uuuuum" every second word 😂🔥
Do you make this to fit a 78mm clutch on a gp460 engine running a had 223 carb I want to put it on a goped I’m sure I wouldn’t be the only one interested
So how many 100's of dollars does this 1 HP gain cost?
***** Not when you consider power to weight ratios. yes 1 horse power for 300 bucks would be ridiculous for a real car but considering power to weight, that 1 horsepower for a hpi 5sc would be like 100 horsepower in a 2900 pound car.
***** Its the same as a 300hp street car gaining 100hp it was 1/4 of the total hp so not that stupid
*****
It's $275
Red Long This test is completely useless... In a real car we don't test HP out in the Crank because its worthless and completely useless.. ANY ENGINE with no load can gain shit tons of HP out of the most stupid modification shit even changing the filter can affect your HP that is why we do a Dyno at the WHEELS because it takes into consideration drivetrain loss and total weight of the car.. Unless this is done in a BAJA and Dyno the wheels they cant prove they gained shit... Its like buying a brand new spanking Mustang Shelby GT500 and then realize ford just specd out the Crank HP and in fact your supposedly "500HP" car only has +/-427whp a rather different number you see.. If you put that into perspective this S/C can only be adding .20HP at most and that isn't worth the 275bucks price tag.. You could probably gain more than that with just higher octane fuel.. And well "Adding" its a wrong word since S/C don't work on 2 Strokes to begin with.
.
when I was younger it was al about how fast, now I think more torque is the goal
More torque lower rpm.
Would like a gas/nitro crawler but
Rpm too high
Torque too low !!!
Can't wait for the March RC Mag to come out......I'll finally get to see an actual, unbiased, multi-engine X-Dyno test of the 'charger.....
31% gain in power divided by $ 275.00, is it worth it ?. Will this extra HP be usable to an average RC Joe ?
Have you tried these engines running at sustained engine speed of 17,500 RPM, then you will see the difference. You have not indicated the engine temperature before getting the data and other atmospheric conditions.
Just my insights....
pinoyeh you'd obviously go to a taller gear set and try to keep the rpm's where the peak power is (11,000-12,500 or so) rpm does. Ot equate to horsepower. As you can see, the power rapidly falls off after 13,700 so why you'd continue to rev it higher is a mystery to me.
How long do we see the belt to last on these?
Did they jet the carb after installing the charger? If not, then they were faaar off the max output😐
The supercharger comes after the carb. Therefore an adjustment is not needed^^ it can help, but only a very little bit at max power, when the carb exceeds its usual airflow range
DerKrawallkeks For every power increase, you have to rejet the carb (or doesent this apply to RC car carbs?)
ok, i just found it weird, because if you tune a normal 2 stroke bike engine, then you HAVE to re-jet it, or it will run too hot and destroy the cylinder and piston...
Yeah these are alot different
thanks but I would spend the $400 on a bigger motor....and get more power....
Seriously.... $400?????? ouch
Johan Visagie yep way over priced
Ramsay i think this test is BS and i think the supercharger is BS and this is nothing more than a money scam
James Palmer agree
the Zenoah G320RC cost 299
Mostly an average is taken after 3 tests?
What modifications is need in carburetor when use this supercharger
do you do these superchargers for a marine .90 glow engine ( 15cc). i have a sc91 , so i am wondering what could the SC 91 reach without any engine mods and the addition of your supercharger..? at present the motor is around 2 bhp
Will this fit on the losi 5t 2.0 truck ?
I wanna see you do this test with like the weight of a person like if someone was riding a goped it has resistance i wanna see you dyno that and if its an improvement then well talk!
can i fit this to a 30cc motor ??
How muxh would it add to a 5 hp 35 zenoah engine
So amusing, the graph is shit, really, this is a complete joke, they let off the throttle and the line continues to go to the right, the bottom is RPM and apparently the rpm's still gain when you let off... All this system does is flood the engine with fuel and air and spilling loads more out through the exhaust.
***** ya the RPM rising to the right is confusing the hell out of me hahaha
joshua arnott lol... I would expect way more out of them.
+joshua arnott the graph is there to show potential customers of the 'power increase' which is complete bull, they are trying to sell a product fraudulantly.
prove it, bravo. they've proved their claims.
+joshua arnott well... anyone clever enough to make anything that works would know how to make a basic fuckin' graph...
I didn't know adding a supercharger added 2hp at idle
good point but it is possible that it would build some boost at an idle of 6k rpm
You can make 2 stroke engine work with boost. only thing is you just CANT make it without modifications to carb and other parts. Allso if you "un boost" boosted 2 stroke it wont work without modifications.
Would this work with rcmax and alx engines
OK, found the dyno vid. I would have like to have seen the fuel curved optimized on the base motor. If it was set up rich and the blower caused it to go lean it might account for as much as 20% of the increase. And not familiar with inertia dyno,
automotive dyno measures torque, torque is what does the work, hp is just a computation based on torque and rpm. If they haven't spent several hundred hours on the dyno ans shredded a pile of motors its still backyard amateur time.
whats the torque on these little motors?
What engine was it tested on , as it can't work on our engines ,you need an exhaust valve system an inlet valve system , crank case induction not barrel induction (like ours ) the engine would be so modified that's it no longer an engine that would resemble a Baja motor , it can be done but only on special motor , some snow mobiles have them fitted but arnt a 2stroke in the common sence of what a 2stroker is ...?????
the dyno remains accelerating due to inertia from the weight of the flywheel
They need a brake on their dyno maybe?
ExplitPlayer Yeah, I know. I'm always expecting each sentence to end with an "...in the world" with a deep, Mortal Combat "Finish Him" voice, for extra 'coolness' ;)
This is pretty awesome. A lot of people seem to be talking out of their ass about your products, though.
How long will the supercharge last
Wow... Can u do the test withe tuned pipe?!
It's not a stock engine. The first thing he said was it's ported with a 990 carb. So that engine should be making more hp than that stock.
ts the same engine in both tests douchebag
+Tim Braithwaite clearly you can't read. I didn't say anything about there being two different engines.
it wasnt a test from stock. it was a test to see power increased with a supercharger
THE BELT is sapping loads of power. a direct drive is needed
And the belt has stretch so will slow and load down when revved up. Total crap.
Hey, I have a turnigy 1/16 nitro buggy with a 0.7 upgraded motor do you have a supercharger I could use for that type of motor?
You don't want one... Just makes the engine run lean. The engine already sucks in as much air as it can get... Not worth the money
Yeah iy runs lean. And just makes the piston loose compression quick.
I had one wasnt happy. But yeah it looks sweet installed lol.
Now planning on getting a SC for my baja, but i dont know if its the same as a nitro engine. Since this one has its own ignition so running lean wont be a problem. But im more in if its going to gain hp.
how about you dyno a nitro engine? Also, the data input can be modified on a dyno run. IE, Ambient Air temperature, air pressure, and humidity. There's also a HUGE low end lag, one I wouldn't say it's worth it u less you ran a higher rpm clutch.
+Do M ambient air pressure doesn't vary by 32%, its more like 5%
Where I can buy it? Supercharged?
I got a super charger on my rc 5.9 nitro had it tested out.and.it holds 25psi thats more boast than real turbos work.that out.
Much lower cfm required, so it makes a higher psi easier
Benefits of a tiny 5.9 engine I guess
Is it worth getting or not? I'm looking at one for my savage k5.9, just to say it has one, but if it doesn't improve the performance, or drastically reduces the life of the engine, I won't be getting one
From what I’ve been hearing about these, don’t
Should of took both tests at the same rpm. NA / Force Fed
Where did you get that dyno?
Hey Bob could I ask you a question buddy the supercharger is awesome man now the question is you have a two speed and a 3 speed transmission what is the biggest difference I know the other gear is that for speed and do you have any videos on that I want to build me a 5 B and I was thinking of getting either the two speed or 3 speed transmission I'm disabled in a wheelchair a lot of my friends do speed runs with 18 110th cars and I want to do something different with a 1 fifth scale build it up if any help would be appreciated Bob thank you very much been watching your videos for quite some time sorry I haven't subscribed until now I think you are awesome man and all your videos are great brother thank you very much you're good friend Roy
What % is the 4:1 pulley make ????
will this work on the Rovan 5b?
am I the only one who thinks that the carburetor is in the wrong place? should not superchargen sit last? if you know what I mean.
Oliver Österlind Prob mix the air/fuel well though
For superchargers driven by the crankshaft of the engine, it does not matter if the compressor is upstream or downstream of the throttle body. For a turbocharger where the compressor RPM isn't directly tied to the speed of the engine, however, the compressor should be upstream of the throttle plate.
Oliver Österlind on a setup like this, you have to put the carb upstream of the blower as the carb is acting as it's own fuel pump and requires crankcase pulses to actuate the diaphram in said pump.
I wish you guys created 80cc superchargers
My Enya 80 in my Copter wastes that! But its a glow thing!
shldnt the turbo install on the exhaust of the engine why install at the input?dun understand y..wat ur showing is pumping more air into inlet..
As you can see the super charger is more inconsistent then stock imo it's not worth it if you want power gains get a bigger motor or port the intake and exaust get a bigger carb and bore it out
I def agree that they let off early on the non blown motor but the blown motor after. They let off the graph is still goin up because the inertia wheel is spinning the highest right before letting off.
Does It Work?
No
Let me explain things to you people.
A supercharger uses engine power to create power. It's parasitic power. In the end there is something connected physically to the engine that spins something else to create boost.
Further more, any boost over atmospheric pressure is a gain. As long as the air fuel ratios are proper.
That means this is real and it works.
That is all.
Lel no, you act like you know what you're talking about but you have no clue
You can't produce meaningful boost in an engine where the exhaust and intake ports are open at the same time, which is the case with all piston ported two stroke engines such as this one. Your BEST case scenario is you just push excess fuel/air/oil mix out the exhaust port. Any pressure gained from the supercharger is vented to atmosphere the instant the intake ports open, as the exhaust port opens first and closes last.
If you want to boost an engine you need to be able to force more A/F mix into the cylinder than will naturally fill it when it's N/A. And you can't do that in a piston ported two stroke.
@@TestECull ^^
Maybe learn how a two stroke engine works and how that would negate using a supercharger or turbocharger. I love the conviction you spew your bullshit with, it’s kinda funny.
I'm confused is it ported or stock? because stock isn't ported LOL! ohh gezusus!
夢があって良いけど２サイクルで加給機使えるのはディーゼルの様に直噴出来る
構造が必要。
Something is out-of-whack with this video. The chart is wildly out of sync with the test. The L-R direction (X-axis) in the chart shows low-high engine RPM while the Y-axis shows HP output.... so, why does the RPM continuue to climb while the video clearly shows the engine revving then slowing? In my experience, most dyno tests need to be run over the course of at least a full minute to map power output over both engine speed and engine load changes. How do you "dyno" a motor without a dynamic load!?
+Grant Arnold its just the animation for the graph being out of synch with the audio of the video if you expect a real time readout [which it is not], but you can clearly see the the throttle is wide open the entire time the engine tone is ascending
+joshua arnott also, my guess is they used a generator as a dyno and measured the wattage coming out of it
+joshua arnott ... okay, that does make sense. the chart is the output of the test (not in sync with the video/audio) and it's basically charting the wattage at the flywheel as the motor revs to redline. the power increases are pretty amazing, in that case!
Dynamometers utilize a generator as a brake in how they're wired they provide resistance to the engine and by mathematical calculation in the software produce hp and torque readings. Same for motorcycle, atv, and auto dynos. I used to own one myself. You also have a delay from the signal through software to screen as well the video being synced. A couple milliseconds makes a difference but meaningless in the scheme of things. I'd say this is a pretty accurate depiction of their product. Yet in comparison to car Superchargers it would be considered very low quality but for an Rc car it's pretty rockin.
Grant Arnold genius...the graph shows the power curve from idle to peak rpm. No engine makes peak hp at redline.
This guy sounds like Owen Wilson..
sadly supercharging only works with valved 2 stroke engines , so i call BS on this one :
the graph is sh*t , because the rpm still rise when the throttle is clearly shut , so no actual information can be taken from it.
the dyno would be nice , if you were to show it showing nubers , which you didnt , you put in a picture of a pc screen , so yes , BS
drache444444
Clearly not
Turbo and supercharged 2 strokes has been a thing for decades, and does work. He'll diesel 2 strokes have to have a turbo or supercharger to run. Ski-do snow mobiles have turbo 2 strokes in them as well.
@@TheAmericanUhate
Yes, of course supercharging 2-strokes is a thing, but only on 2-strokes with exhaust valves.
the Diesel 2-strokes that youre talking about have inlet and exhaust valves and dont use the crankcase for pushing the gas exchange in the zylinders , they use a turbo or supercharger for that. theyre basically 4-strokes where youve put the inlet and exhaust in the same place, and thats inbetween the compression and power stroke at the lower deadspot.
ive never had a look at ski-do snow mobiles, but eather theire diesels (like i explained above) or theyll have a rotary exhaust (and most likely also intake) valve making it possible to be charged.
on a regular 2-stroke (like all 2-stroke model engines ive come across) charging would only have negative effects.
you would be pressurising the crankcase, hindering the piston from pushing into it on powerstroke and when the gas exchange happens the over pressure would push straight to the exhaust port (which is open at the same time as the inlet port, most often even longer than the inlet) and because of fluid dynamics not even exchange the entire volume of the zylinder.
theres a good reason why 2-stroke technology went away from a high pressure gas exchange to a low pressure slow flowing gas exchange using the tuned exhaust pipe
@@drache444444 At least they have the carburetor in the right place this time, unlike their older nitro engine kits! lol I asked them years ago how they could set it up as a "blow through" system, without the supposed "boost pressure" blowing the fuel right back through the needle valve and back into the fuel tank.... I never got a response. Can't imagine why... haha
@@billymanilli Oh wow, so that absolutely confirms my opinion of these "dyno tests" of RB "innovations".
they just lie.
Im just stunned people still run nitro. I guess its a 1/5 scale thing. You have to have a bigger RC than everyone else. : /
Nitro is very popular in 1/10 and 1/8 scale...this however is not a Nitro. Its a 2 stroke Gasoline engine.
hello cool guys. the first engine is ported.. the second one is not ported.....
ported means more duration, a bigger exhaust port. when you file the port bigger the power in low rpm is gone away... my ears hear an engine without power in the bottom end.
You always need some power in bootom cross motor power you want. not puch maxi effect or vespa ciaou
the super charger must take away a lot of power when it's not working at low rpm. also because the transmission is not geared down but geared up. my experience learns me always gear down from crankshaft when you try to gear up..... the engine dont like it especialy two stroke's they need to run free
groetjes uit nederland
Lude Boukema they're running the same motor. Even with the port timing raised forced induction does work.
Lmao they should be sued by someone with any sense
You can't supercharge a two stroke, it blows right through. If it was a four stroke, it would definitely work.
Wrong! There are plenty of turbocharged (and some supercharged) 2 stroke engines ... i worked at a snowmobile dealership and we fabricated MANY turbo kits on 2 strokes ... all with massive gains. Tested with a water brake dyno.
Very Nice vidéo . Up . Up
Shoddy "dyno" Snake oil. I've tossed lots of customers "power adders" because they are just jewelry on tiny displacement engines. We always recommend carb, crank mods and juicing that work opposed to bling that removes power.
I would spend my money on a bigger displacement engine with the same foot print. Match a good tuned pipe. Like an OBR setup. An engine with this gear boosting power is just asking for 1/2 the lifespan. why bother.
Lol it's a 2 stroke your "power gains" are from it leaning out
dyno test lrp .30🤔
Why lie to us?! it simply will not work on a 2 stroke engine
@Chris & Kristin Olson Its a zenoah engine the exhaust and intake ports are open at the same time for about 5d.
Will proof is in the application. I bash with a Rampage and a 32cc engine. My buddy and I bought ours at the same time and when ever we drag raced they were equal. I put this charger on mine and it has much better acceleration at mid range and better top end than his. In 100 feet my truck is 10 to 15 lengths ahead of his every time we try. Is it 31% better, NO. Is it worth the money I would say YES if you like cool things to play with.
centrifugal superchargers aren't screwtypes used in cars. I am guessing less efficient at lower rpm.
stupid, when you let off the throttle the RPMs do not keep rising......
My 1/8 has 7 hp electric , and my savage 25 has the same as that lol
That is true, but your engines have no where close to the torque value. HP can be found with RPM's, which is why your 29,000 rpm .25 can see such high output numbers to begin with. Indy car engines could be thought of as example. They are extremely fast reving and make huge HP numbers with such a tiny stroke, but if you put that engine in your typical heavy framed grocery get'r, you wouldn't get two feet before you burned out your clutch or stalled the engine from lack of torque to get moving.
Tuffenough4u Indy cars are also methanol
i like the idea of a turbo or super charge, but the idea it being on a rubber belt plus no way to oil the the turbo an due to the weight of the fan, an belt drive i dont beleave this would work , it prob would for a short time , i just dont think the belt is keeping up with the turn of the crank it slipping like crazy , an no way the chart is real
It is oiled by the intake charge being pressurized and containing oiled fuel...also the fan wouldn't weigh that much, especially since car superchargers are powered by soft rubber belts
+gundorethemighty if it were a suck-thru carb setup you owuldnt have to worry about it considering it 2-cycle fuel
or you could buy a OBR Reed Valve G340RC engine that puts out 9.4 H.p for probably cheaper.
+behemothfan666 given that OBR Dynos there motors with Bartalone pipes and a loaded Dyno, yes it puts out 9.4 HP.
+Strixx I'm not stating they don't. but let me just say this, legends such as Scott Finlay and Trevor Simpson are only just getting to the 8 HP mark with both reeds and PP.
+Strixx oh and OBR dyno test with many different pipes but I think you'll find that there preferred company is VRC and along with being the most successful with 90% of "there" engines is the VRC pro pipe.
Trevo Simpson has been building these LONG BEFORE they were put into RC cars.. AND HAS WAY MORE EXPERIENCE than these fools.
I know Trevor personally, he use to build all my motors when I raced GoPeds.. And yes, he has made 10 HP motors.. Maybe not G23-G28 s..
All I can say is that I run an OBR G340 Reed Valve Stroker motor in my Vekta.5 and that thing hauls ass. On all of OBR's Full Mod and Competition Engines they send a Dyno Sheet with their motor. I am very happy with OBR along with Turtle Racing, DDM, and Bartalone Racing. For $550 for a built engine that is tuned for 110 octane and has lasted me over 25 tanks of gas without 1 issue, I am happy. They also build custom 2 cylinder 57cc twin engines that put out around 20hp. Now I know there are other companies that build motors and do fine work. I am just happy with OBR. I have bought 8 engines over the last 8 years from them and love their work. OBR is probably the number 1 engine builder for 5th scale RC vehicles to my knowledge.
My whole point was that a putting a Supercharger on a stock engine is costly and inefficient compared to buying a built motor to begin with. Now maybe putting one on a built motor may benefit some.
Nice
These comments still complete me
More lean more hot more damage more money for absolutly nothing will just be more quick to destroy it 👍
I could buy so much more with $200 than just some better airflow
This..this makes no sense.
Go back to school then
@@KalLanPIDT no he's actually smart enough to see that this is bullshit, meanwhile you apparently believe this bullshit so you're the one who should go back to school
You don't need valves to compress air. You just need restriction. If your compressor (supercharger) can push more air into the crankcase than can leave, then you get higher air density. It's not that complicated.
“Hurr durr reed valves are as weak as my feelings because I said so guise”
ok lets get going here use a 26pum engine i have a QJ motor
