I love superchargers.
Thank you, I really wanted to understand it's function and now I grasp it perfectly...its what happens when a turbine has unprotected relations with an air compressor.
Can you make a video on how to increase performance on a N/A?
change camshaft, header, exhaust, add cold air intake
@@colinleder5683
Is camshaft a good thing when having a variable valve?
@@UltimatumDemon Cant help more im not a mechanic ;)
Pretty much dump more fuel (up to a point), then fiddle with ignition timing and compression(?) .Change camshaft. Also make sure things like air filter,egr, exhaust work properly. Source: Automation (game about building cars)

Wow, the best supercharger info video ever- great graphics!! 👍
This just helped me figure out which pulley I’m putting on my Mini, thanks 👍
Waow fidget spinners 0:39
Lovey cam fidget spanners
Thicc fidget spinners
Great and informative video. Great job chaps.
Beautifully explained
excellent video
So when specing a root supercharger do you size pulley based on engine size displacement and boost target taking in valve overlap etc? or would you also factor in the low VE of the engine (say is has 2 valves per cylinder and is old).Would your calculated 8psi positive pressure based on the full engine displacement turn out higher because of poor VE? IE if the engine had a VE of 80% would you meet in the middle and calculate it at 90% engine displacement because of the old design\low valve count?
Can someone tell me what brand to look for I want one for an 86 f150 with a 351w
I guess instant power delivery would be way more favorable over revving the nuts out of your engine, just to squeeeell the tires and losing the boost when shifting in a turbo car
great man superb knowledge
Thanks for this video. You're the only one used numbers. And the best is your numbers are right, found this in expensive books too. Many commends here asking how to get 102%. Please tell them how a BMW M5 V10 makes 105% cylinder efficiency filling. The air dynamic is the key. Borg Warner says the maximum efficiency of cylinder filling is 270% with charging. Have seen little VW 1.0 tsi, 3 cylinder, with 263NM. 300NM per Liter is the new future for high performance, means a 5,7L small block should reach 1710NM, but he didnt. My question is makes a doubled filling efficiency double NM one to one? Means a 200 Nm NA engines, doubles AF filling with boost, makes 400NM? May less ore more torque when you burn double fuel?
Just found you…. Excuse me while I watch every video
Thanks for this channel !!!
The only thing that could make this channel better is if you had a texas accent , haha
Love from Dallas !!
Ive a tsi and thats really good to know
Hence the installation of aftermarket superchargers is easy, can I add a supercharger to already turbocharged cars, in a way to marriage both of them in order to prevent lagging and to gain better performance, in another meaning the best of both in one(We usually hear about 2 in 1 or whatever in one in most good products, but can this type of marriage work on cars). Has anybody thought about this before?!
Does anyone know where the clip at 00:21 comes from and if possible the owner of that car
@Random Boiii _ the short vid of the car
Does a supercharger make your car less reliable since the compression should be higher?
Does anyone know where the clip from 3:33 comes from?
Is no one going to bring up that fancy ass chair the dude at the very end of the video was on? It was like a robot arm connected to a chair
These are the things that really make that v8 zoom
The only way a v8 goes zoom
And the fuel
@@Wabeeninc false. A stock V8 can easily go zoom
If the h22 can reach 102% ve does it means it's kinda has boost even tho there isn't forced induction ?
No, because engineering and physics.
IMNOTA
Technically yes as boost is pressure above ambient as a result of resistance to flow however it would be very difficult to measure given it's so slight, fast, and occurs in the cylinder as the air "stacks up" and compresses ever so slightly before the intake valve closes with just the right resonance.
Though it's quite debatable if this really qualifies as "boost" or not. It more like the "elastic" nature of air.
Pls do video of vacuum operated supercharger bypass valve vs operate by wire type of supercharger bypass valve control by ECU.
Is vacuum operated supercharger bypass valve continuously self regulate to maintain a minimum delta p?.
Example 1: manifold air intake pressure at -1 psi and bypass valve in modulating mode for +2psi at supercharger discharge. Manifold throttle body 30% open.
Example 2: manifold intake pressure at +2psi. Bypass flap further closes a bit for +5psi at supercharger discharge. Throttle body >35% open.
Case 3. Air intake manifold pressure at +7.5psi vs supercharger discharge also at +7.5psi. Bypass flap in closed position. Throttle body >50% open.
Example 4. Manifold air intake at -5psi. Bypass flap in fully open position. 0psi at supercharger discharge. Throttle position 23% open.
It is possible to change a ECU operated bypass valve, in a supercharged Mercedes, to vacuum operated bypass valve to try the type able to continuously self regulate for a slight DP before intake manifold pressure get above -1psi?.
Fyi, idling at 750rpm to the manifold intake pressure is at -7.5psi with throttle body at 17.2% body. MAF at 5.4g/second. Very very slight positive pressure of +0.14psi at supercharger discharge.
Regards.
What’s the crack with pro chargers?
Is that a combination of turbocharger compressor but powered via belts?
It's a centrifugal compressor.
@lawnmowerman127 These are centrifugal superchargers created by the company "ProCharger"
Oh I see!!
Thanks for help 🤙🏼
1:54 Fidget spinners 😂
I only clicked on this video to see if someone commented this 😂
The OG fidget spinners
What do you call the third forced induction 2:34
Im also curious
anyone making a cvt supercharger pulley setup yet?
Bro that’s crazy just learned more in 4 minutes then I did all school year in math
can anyone tell me best video editing software and plus it should be easy to work on!
plz
Davinchi resolve is great, but you need to have some experience and a bit more powerful pc
Mārtiņš Indāns ok thanks 4 telling

The section in this video on Volumetric Efficiency is conceptually incorrect. VE is not a volume ratio, it is a mass ratio. A piston engine is a positive displacement pump, it always pumps the same volume of air no matter what the conditions.
And as other VE videos are wrong, there is no such thing as "Wasted Space" in the cylinder. Air in a continuum does not act that way.
Doms 1969 Dodge Charger ‘s supercharger is so beautiful
0:52 which engine is that?
S52B32
I like superchargers over Turbos, is that just me? I mean, Turbos can create more horsepower over a higher RPM, but superchargers are more consistent and I feel would be greater to control the power on tracks.
I agree with you on that part but I personally like turbos for the sake of economy in daily driving
@@christophercervantes5346 Yea I agree too. Turbos though are very efficient.
And they don't fail as often, turbos are way more sensitive. =Superchargers are cheaper
why do you say supârcharghărs instead of supercharger?
He is British, as you can tell...
Lepsze niż miłośnicy 4 kółek, że tak pozwolę sobie zażartować 😂
How is the background music called?
song name please!
Now do the same for turbochargers
Please.
Aka fidget spinners that's actually an air compressor
What causes superchargers to whine?
They're straight cut
There devil's that love to cry 😈
Wassup guys how is everybody doing❤️
How about both? 😏
It's all 'bout that air ya'll...
I spy a classic Mini 2:33
Yes, that video is around there if you look for slide throttle bodies in youtube
That's why Supercharger >>>> Turbo
Sandro Sobreira no
No
why? i heard no reason why its better
No Twin charger>>>>>>>Super charger
Imo supercharger vs turbo is a very subjective preference. Personally i prefer the superchargers, the bigger roots style ones, as the sound the make and the linear power delivery the help to achieve is orgasmic.
I swear that's a fidget spinner in the thumbnail
Learned more then in school
Fuck me
Came here because I wanted to know how Mad Max's car worked.
All you need to know is that there's no replacement for displacement.
Your graph is wrong at 1:08
The volumetric efficiency explanation is not 100% correct. An engine pulls air with negative relative pressure, that's why the air enters the cilynder. But the fact not 100% of the displacement is considered is because the final pressure at the intake stroke is lower than atmosferic pressure. So it means you have 80% e.g. of volume at ATMOFESFERIC pressure. But obviously the cylinder gets fully filled , just at a lower pressure than atmosferic.
Yeah exactly
First
Donut media science garage did it better
This covers more of the math and numbers side, which is a welcome change from the kindergarten level tone that science garage uses
Too much talk
I wish this video had constant, pointless, repetitive, monotonous and distracting music..preferably something infantile.
I love superchargers.
