I just found your channel today. There's something about hearing that little jet engine rev up, that makes my eyes widen and I get a big stupid grin on my face. Well done. This is amazing.
I appreciate what is being shown here for its novel application of jet propulsion to the vehicle. Fifty-five years ago the older kids (budding mechanics they were) in the neighborhood adapted a huge West Bend two-cycle chainsaw engine to a lightweight go kart frame. That thing could outrun the wind. Even the bravest of the group wouldn't take it out for a second run. These guys had the brand new US Route 1 bypass that connected the northern terminus of the Roosevelt Blvd. to a distant point near Levittown, Pennsylvania, for their test track. That motor was screeching every time some young fool made a pass at 80 mph (estimated) with blue smoke trailing in their wake. The guys ended up putting a 5 hp side reel Tecumseh motor on the go kart which was enough fun to race around the park without someone facing certain death.
right, as a teen my brother let me have his cart for the summer. it was a blast, power sliding through a shell/ asphalt road. he said check the oil level every once in a while and you pay for the gasoline................. so, not a problem.
Oh PLEEEEASE tell me there’s MORE!!! That was so fun! I wish you had looked at the speedometer a couple of times, I couldn’t begin to estimate your speed. Well done Sir!
@@timjames2871 heck yes, I was stoked for the Cleetus turbo LS/jet car combo. I was bummed when he decided not to do it, but I completely understand the safety concerns and why he went a diffrent direction.
@@joshmanis9860 I don't think so. I have friends that can do 80kmh on a long board. So I think having a go kart with brakes doing that speed isnt so bad
Ever since high school when my shop teacher built a crude jet engine to explain to us how they worked, I always thought it would be cool to strap a couple to a go kart. Then you put a much more sophisticated engine on one. Way cool.
Definitely one of the sickest gocarts in the world. Can't imagine the feeling of driving that thing. Also, the sound of that jet engine is just incredible. I couldn't build this in my garage if my life depended on it. Kudos to you man, you're friggin genius.
Because the brakes aren't connected to the engine technically you can be full throttle on the jet engine and then be able to use the brakes and still slow down while you have full throttle on the whole time Because its not connected like a traditional piston engine would be and Because its not directly connected it has no rolling resistance and this combination with 70lbs of thrust would create an insanely fast go kark, amazing video loved it
Problem is that, with the power and wheels being separated like this, it's much easier to skid and understeer since a much larger friction force is required at the wheels in order to slow down. I would love to see this same setup with the addition of another jet engine and a foot throttle.
Pure badassery right there. Sweet build man, I agree with other comments, I'd love to see the difference in power the turbine could produce if you could get it into the airstream, maybe fab an intake duct to scoop air and dump it into the front of the turbine.

That's amazing! Great engineering and fabrication. The biggest issue appears to be the lack of instant throttle control, which must be unnerving approaching corners. Perhaps the next bit of fabbing could be thrust reversing shutters linked to the brake pedal? Not sure where you'd duct the thrust to though!
@@WarpedYT you will have to factor in the total frontal drag and also if your engine isn’t exposed to the direct airstream you won’t get any ram recovery. Maybe build a split inlet to single duct (like on a T-7 Jet Trainer) and that way you can force feed the engine air instead of it sitting in the relative vacuum that is the area behind you.
imagine walking down the street hearing a full-throttle jet engine and u start looking at the sky, then u see him cruising down the street in his jet kart 😂😂😂
I understand what you mean, but (and I'm not sure) I'd imagine is fine in its position for its use, I doubt there's that much of a low-pressure area behind the seat to restrict the inlet. Just my take though
Nice! I once attached a bunch of solid fuel model rocket engines to the sissy bar of an old bicycle. Banana seat caught fire and the thrust didn't last long enough to go fast, but I looked awesome going through that intersection crapping fire from a Huffy!
@@shadowopsairman1583 JetCat makes a turboshaft version. It'd be a lot more powerful but the throttle response would be super slow and the gearbox/freewheeling mechanism would be a pain to make.
I think that jet engine is air-starving because it is mounted behind the seat. Have you considered move it or build a kind of air intake tubes for the engine?
Not really. Look at jet dragsters. To scale they look about the same relative amount of space. My cousin's jet drag car the intake has a cage around it than makes a funnel shape towards the turbine but its like a wire fencing material and its within id say a foot maybe ten inches of the seat. The turbine ia right behind you
Ever since I saw one of those jet engines I've entertained the idea of using the exhaust of one through a diverter valve into a turbo-turbine and then plumping the compressor output to the engine intake of a car or tuck. Free boost, just actuate the diverter from atmosphere to turbine when ready. No excessive heat or back pressure on the engine either. Whadaya think? You already have have most of the key stuff right? I know that jet is the better part of $2K; but turbos are relatively cheap.
@@krotchlickmeugh627 You've already tried it? or are you just another smart-assed skeptic. There are videos of turbos being converted to jets. Do you actually think a turbo turbine would actually make enough back pressure on the jet to stall it or burn it up? I'm not incline to agree.
@@golgothapro lol sure bud. I am just a smart ass. Your statement was genius and youre a genius. Try it. Then afterwards. Headbutt a bullet i hear it makes you smart.

Hey there! I'm a part time watcher, love what you've done with the briggs, transparent heads, nitro, turbos, etc. I really enjoyed seeing the diesel kart too. In past lives I have been a Go Kart racer and a Gas Turbine mechanic. Seeing you combine the two tugs at my soul, watching this video, I had several thoughts I'd like to share with you... After pressure washing you should immediately do some maintence on your bearings to keep them in top shape. I noticed in the first shot of you rolling the axle that the brake disc is a little out of round. While I'm thinking about brakes, you should really consider adding front brakes, especially for stability in a straight line once you break 50 with that thing. Which leads into my next point, I'd recommend looking for a used AiM MyChron system to use as a GPS and date logger. I believe it runs on a CANBUS standard too, so you can add whatever sensors you like. I might get a little worried that the Aluminum brace you built across the back will elongate due to temperature and cause the chassis to bind up in the rear, then again, with enough air movement and surface area, it might be sinking the heat well enough that it's not a problem. You're going to be drag limited real soon, might already be. two easy ways to cut that are a nose and a steering shaft fairing. Past that, the battery is a boat anchor, there are much smaller ones that have enough power to do the job. So I want to throw down the gauntlet and make a challenge. Build a jet powered Kart that is safe for competition near others and can run for 20 minutes at a time. Ice cold tires were also a big factor in your spin, not to mention the lack of rotational mass on the rear axle to offset the braking torque, front brakes would have added a lot of stability and keep you under control long enough to correct the error instead of ending up like you did. Just an old racers thoughts. Keep up the good work! Love your channel!
Chiming in a bit late here. These engines are made to be in the air flow. They can compress better and produce more power if they get the air shoved down their throat. Like Ram air but way better. You sitting in front of it hinders the performance. The faster it goes the more air it has to swallow and the better it performs. Otherwise awesome vid!
@@bricaaron3978 absolutely the air flow is still same but the combustion rate goes up making the air fuel mixture not balanced and the combustion not good
@@parisgiovanos766 That's interesting. I was just wondering how much performance would be improved if the engine were left in place, but a duct were installed that curved around the seat so that the intake was exposed to the oncoming air. I know that many jets have ducts in front of the engines, but my assumption is that they are mostly straight-line, without any major bends/curvatures.
@@bricaaron3978 You can absolutely use ducting to improve airflow. Engines/turbochargers in high performance cars (while not exactly the same, obviously) are often fed by scoops.
@@pontifexinferno Thanks for the reply! I knew that, but I wasn't sure if things would be the same for a jet engine. I didn't know how certain factors like turbulence, etc. might or might not affect a jet engine and didn't want to make an assumption.
@@jasongrim2027 he could probably make a nice 5 gallon pressurized bladder tank to reduce the amount of sloshing going on.... how aerobatic aircraft do it.
@@StrelitziaLiveries Still less efficiency, plus you don't have suction at the front giving you extra force. If you have 2 jet engines you can easily set them on the sides, or for single jet preferably lift it upwards or have ducts on the side to smoothly allow air intake from the front (as a bonus you can filter debris as part of the design)
When building vehicles with jet engines, adding a secondary engine like a gas one should add more torque at the bottom end while leaving the jet engine to handle top end power... that would be interesting 🤔
That engine could produce enough for take off. he took off slow in the first run, second you can see he took off faster on purpose but he still didn't give it all it can do. besides adding another engine is increasing weight
You'll be surprised how fast that turbine engine could push that cart at launch. He was obviously being conservative with it. Adding more weight would hamper not make it any faster. Might as well just go all-electric for acceleration and top speed mixing the two would be pointless.
Great engineering and a lot of fun. I hate being a party pooper, but The Rover Company in the UK built a jet car in the 1960’s which they hoped might be the future for cars as it was becoming for aircraft, but they had all sorts of problems such as fuel consumption, fumes/heat dispersal, throttle response, braking as you are finding. The car did go well and reached 150mph in Belgium on a straight road. Douglas Bader, the WW2 British fighter ace, flew the Gloster Meteor after the war and he thought with 2 huge jets this thing is going to go like hell. When he gave it full throttle for takeoff, however, he said it trundled down the runway ‘like an old lorry’! I think it’s probably a case of ‘horses for courses’.
AWESOME! you built EXACTLY what I've been wanting to build, but I wasn't sure if the 67 lbs of thrust would be enough. You tested/validated all my design questions. Thank you! You might want to try foam in the fuel tank to suppress the fuel sloshing (and maybe a bigger tank) :D Excellent build man, you're living my dream!
@@joshuagoodsell5952 sorry for the delay. Catching up ... google chief aircraft, they have a couple different brands like Jetcat and others. Click 'Radio Control' on their homepage and then 'Jet Engines'. Enjoy
@@joshuagoodsell5952 Jetcat is a good bet buddy. You'd need one putting out at least say 20kg of thrust (200 Newtons - is how they'd be described). You can get other brands - like JetsMunt, King-something, Jet Central. You're looking at 'model jet turbines'.
Great engineering project. That jet engine deserves to be in sturdy Ultralight Airplane. Hight power to weight ratio. Use a lot of fuel but that can be controlled.
First I was thinking you might need two JetCat engines but then I thought about the flight wing and figured that might be too much. But this was awesome! Definitely want to see what the top speed looks like
That was awesome...however I cannot help but think of "uncontained engine failure" and how one micro-fracture in a turbine fan blade could cause that whole engine to blow apart at the speed of sound... I mean it's great because the metal fragments would rip your brain apart so quick you wouldn't feel anything, but I'd consider welding a nice piece of metal in front of the engine as a "just in case" measure if you're gonna keep this thing. LOL.
I like your knowledge, talent and was excited to see such a crazy project that I have dremt about since I was much younger. I really am amazed at your machined talent and equipment that you use to construct these projects. You are what I wish I could have done with my spare time. Thank you sooooo much for delivering the dreams of many in their youth. Great project, exciting to watch and imagine. I love the sound of the jet engine. There is just something about that sound that makes kids of all ages just SMILE. Thanks for the dreams.
@@eugene9852 i mean everything up to 200kmh wouldnt remotely be a problem. I think that think wouldnt go faster than the chassis can handle. Just needs a decent driver
Dam that jet sure sucks the fuel up! Lmao imagine the cost to keep your tank full if we all drove with jet engines! The price of gas is so high rn! It sucks.
@@WarpedYT 😂 gas was at a 1$ a liter. now its a $1.20 a liter for regular. N 1.45 for premium! I thank god I have and drive a Chevrolet spark rn! Cheapest car available! But great on fuel! 😂
Now you need to make 7 more so we can have a real race. You could name this event, Go-Kart Carnage! And each Kart will have special abilities. One could be oil shoots out at the back. Second one could be you drop land mines behind you.😶
How does it feel when steering, since the jet engine is always trying to push straight forward? Any plans to make the jet pivot (via cables or linkages) when you turn the steering wheel?
When you think about it though, that’s essentially what a rear wheel drive vehicle is trying to do. Push straight forward and let the front wheels direct it
@@Trackpad_W4rri0r And a real jet also doesn't pivot the engines. The ailerons are moved to direct the air and turn the aircraft. (And rudders for on the ground).
I could mow my grass so fast with something like this! Sure would like to know what your top speed was, this was amazing! Congratulations on making this!
I believe this little guy has a fairly high bypass ratio, so an afterburner wouldn't do much at all for it. Plus you have the added complexity of designing a variable geometry nozzle out of inconel or similar exotic alloy and getting it to pair up with the gas generator so you get the most out of it without choking it too much...that's a whole lotta work man.
@@jb4661 All jets have some degree of bypass, as it's a fuel lean engine (meaning it consumes more air than necessary for the fuel it burns, and that's critical for an afterburner to work). Most jets these days have a first stage fan (sometimes more stages) that allows some air to pass over and around the engine underneath the cowl, rather than being sucked into the rest of the stages, mixed with fuel, and burned. High bypass means a whole lot of the air sucked into the inlet is actually passed over and around the engine rather than being burned. There are also low bypass (most of the bypass air is used for cooling rather than thrust) and zero bypass engines (pure turbojets, which are very inefficient and identified by lots of black smoke), though they're not very efficient and rarely used these days. They were the first jets, and most Korean war era jets didn't have much of any bypass to speak of. Airliners have high bypass turbofans, as well as the A-10, while most military fighters use a mid-bypass design. You get more thrust from an afterburner if you have relatively low bypass, and with high bypass turbofans an afterburner isn't practical since you're developing better thrust using the fans. The reason why it's impractical is that the operational speed is a big determining factor for the bypass ratio...high bypass being subsonic flight, mid bypass for transonic and low supersonic, and low bypass for strictly high speed. Fans become sort of a detriment at at higher speeds (lots of cross sectional area to contend with, compare these to ultra high bypass fans which are basically turboprops), while afterburners become more and more viable to temporarily reach high speeds. Now, there are exceptions for this, but it's all in how the engine was designed. A VCE (variable cycle engine) is sort of the best of both worlds, as it uses bypass air in subsonic and transonic flight for optimal thrust, then it converts that bypass air into a second burner section when in "afterburner" mode, in which fuel is dumped between the bypass fan and a set of power turbines behind it, so you actually harness more of that power for additional thrust. As for the variable geometry nozzle, that's another hurdle to overcome. The nozzle is painstakingly engineered to have the optimal NPR (nozzle pressure ratio) for the best thrust generation over the expected operating conditions and speeds it might see. An afterburner is going to alter that significantly by increasing pressure inside the engine. This could cause a number of issues, from overheating to developing so much pressure that the engine stalls out from too much restriction. That's why you see nozzles on military jets open and close during takeoff and whatnot...they're controlling the NPR on the fly to give the engine what it needs to be most efficient. At full afterburner, the nozzle is open to its limit, designed to be the perfect NPR will all of that extra pressure and flow, but without afterburner, it chokes back down because otherwise you're losing all sorts of thrust. You could design a fixed geometry nozzle to work with an afterburner, but when you're not using it, you won't produce good thrust. The biggest takeaway here is that if the engine was never meant for an afterburner, it's gonna be tough to get one not only to be functional, but worth the effort to do so.
@@chee6916 I am aware but you won’t use much runway whilst spooling up the engine lol 😂 I know this because as a pilot, we have to do that on short runways so we release the brakes with engines already at max power. It means we can utilise as much runway as possible 😌

I think I speak for everybody when I say I want to see you take this a test track.
Yes a track with banked curves like indy 500!
Al Uncer has a go cart track in Denver
Hit up cletus in florida
@@neilwinterz6994 take it to bandimere haha 😂
your welds are pure perfection "chefs kiss"
this was simply amazing,at one point you tore through the fabric of reality
Ever since I saw one of those jet engines I've entertained the idea of using the exhaust of one through a diverter valve into a turbo-turbine and then plumping the compressor output to the engine intake of a car or tuck. Free boost, just actuate the diverter from atmosphere to turbine when ready. No excessive heat or back pressure on the engine either. Whadaya think? You already have have most of the key stuff right? I know that jet is the better part of $2K; but turbos are relatively cheap.
Thats a great way to blow up a turbo and a jet engine.
@@krotchlickmeugh627 You've already tried it? or are you just another smart-assed skeptic. There are videos of turbos being converted to jets. Do you actually think a turbo turbine would actually make enough back pressure on the jet to stall it or burn it up? I'm not incline to agree.
@@golgothapro lol sure bud. I am just a smart ass.
Your statement was genius and youre a genius.
Try it. Then afterwards. Headbutt a bullet i hear it makes you smart.
"I love how light and quite it is".....until you start a freaken Jet engine up in the car park and the people in the building think there's a jump jet landing outside
I had autocaptioning on by accident when I watched this. As you are flying around the parking lot, it puts up the caption "[music]" Perfect!
this is literally the coolest video/idea ive ever seen
Hey there! I'm a part time watcher, love what you've done with the briggs, transparent heads, nitro, turbos, etc. I really enjoyed seeing the diesel kart too.
In past lives I have been a Go Kart racer and a Gas Turbine mechanic. Seeing you combine the two tugs at my soul, watching this video, I had several thoughts I'd like to share with you...
After pressure washing you should immediately do some maintence on your bearings to keep them in top shape.
I noticed in the first shot of you rolling the axle that the brake disc is a little out of round.
While I'm thinking about brakes, you should really consider adding front brakes, especially for stability in a straight line once you break 50 with that thing.
Which leads into my next point, I'd recommend looking for a used AiM MyChron system to use as a GPS and date logger. I believe it runs on a CANBUS standard too, so you can add whatever sensors you like.
I might get a little worried that the Aluminum brace you built across the back will elongate due to temperature and cause the chassis to bind up in the rear, then again, with enough air movement and surface area, it might be sinking the heat well enough that it's not a problem.
You're going to be drag limited real soon, might already be. two easy ways to cut that are a nose and a steering shaft fairing.
Past that, the battery is a boat anchor, there are much smaller ones that have enough power to do the job.
So I want to throw down the gauntlet and make a challenge. Build a jet powered Kart that is safe for competition near others and can run for 20 minutes at a time.
Ice cold tires were also a big factor in your spin, not to mention the lack of rotational mass on the rear axle to offset the braking torque, front brakes would have added a lot of stability and keep you under control long enough to correct the error instead of ending up like you did. Just an old racers thoughts. Keep up the good work! Love your channel!
Chiming in a bit late here. These engines are made to be in the air flow. They can compress better and produce more power if they get the air shoved down their throat. Like Ram air but way better. You sitting in front of it hinders the performance. The faster it goes the more air it has to swallow and the better it performs. Otherwise awesome vid!
Do you think that ducting would detract significantly from performance if it was curved?
@@bricaaron3978 absolutely the air flow is still same but the combustion rate goes up making the air fuel mixture not balanced and the combustion not good
@@parisgiovanos766 That's interesting. I was just wondering how much performance would be improved if the engine were left in place, but a duct were installed that curved around the seat so that the intake was exposed to the oncoming air.
I know that many jets have ducts in front of the engines, but my assumption is that they are mostly straight-line, without any major bends/curvatures.
@@bricaaron3978 You can absolutely use ducting to improve airflow. Engines/turbochargers in high performance cars (while not exactly the same, obviously) are often fed by scoops.
@@pontifexinferno Thanks for the reply! I knew that, but I wasn't sure if things would be the same for a jet engine. I didn't know how certain factors like turbulence, etc. might or might not affect a jet engine and didn't want to make an assumption.
You really cracked the ceiling for the best sounding go kart of all time🤣🤣🔊
....now just to work out ‘in flight refueling’ so you don’t have to stop.
Step one get another gokart with two separate tanks
@@jasongrim2027 he could probably make a nice 5 gallon pressurized bladder tank to reduce the amount of sloshing going on.... how aerobatic aircraft do it.
1:49 the most badass camera stabilization i saw.
The only issue is the air intake, jet engine air intake should be free of any blockage.
Well there doesn't seem to be any signs of compressor stalls so i dont think its an issue
@@StrelitziaLiveries Still less efficiency, plus you don't have suction at the front giving you extra force. If you have 2 jet engines you can easily set them on the sides, or for single jet preferably lift it upwards or have ducts on the side to smoothly allow air intake from the front (as a bonus you can filter debris as part of the design)
@@jakegarrett8109 I like your thinking.
Daaamn every time when I hear a jet engine gets ready my ears are blessed.
When building vehicles with jet engines, adding a secondary engine like a gas one should add more torque at the bottom end while leaving the jet engine to handle top end power... that would be interesting 🤔
Something I assume would be an issue would be space for the engine and the gasoline
That engine could produce enough for take off. he took off slow in the first run, second you can see he took off faster on purpose but he still didn't give it all it can do. besides adding another engine is increasing weight
I'm thinking this, but an elecric motor with regeneration breaking instead of gasoline
@@LazySpaceRaptor or have the engine run a generator to a battery like a jetliner
You'll be surprised how fast that turbine engine could push that cart at launch. He was obviously being conservative with it. Adding more weight would hamper not make it any faster. Might as well just go all-electric for acceleration and top speed mixing the two would be pointless.
That was sick as hell dude! Keep doing what you're doing, I'm wanting to see more of what you're doing..
LOL that's a lot of thrust for that little engine. I would have never thought that it would have pushed you around like that
They spin at 100,000 rpm at idle bud.
@@krotchlickmeugh627 100,000 at 100%
Its a jet engine 🤣
Great engineering and a lot of fun. I hate being a party pooper, but The Rover Company in the UK built a jet car in the 1960’s which they hoped might be the future for cars as it was becoming for aircraft, but they had all sorts of problems such as fuel consumption, fumes/heat dispersal, throttle response, braking as you are finding. The car did go well and reached 150mph in Belgium on a straight road. Douglas Bader, the WW2 British fighter ace, flew the Gloster Meteor after the war and he thought with 2 huge jets this thing is going to go like hell. When he gave it full throttle for takeoff, however, he said it trundled down the runway ‘like an old lorry’! I think it’s probably a case of ‘horses for courses’.
Looks like great fun, would love to try this!
This is one of the coolest things I’ve ever seen. GOOD FOR YOU!
Dang I wish you had a nice straight track that went on for miles so you could do a top speed run.
Either way that things AWESOME!!
I put that wee camera on all my rc planes and cars. The ability to edit is pretty nice and honestly it's an amazing wee thing
AWESOME! you built EXACTLY what I've been wanting to build, but I wasn't sure if the 67 lbs of thrust would be enough. You tested/validated all my design questions. Thank you! You might want to try foam in the fuel tank to suppress the fuel sloshing (and maybe a bigger tank) :D Excellent build man, you're living my dream!
Where do u get a small jet engine with that much thrust asking for a friend thanks
@@joshuagoodsell5952 sorry for the delay. Catching up ... google chief aircraft, they have a couple different brands like Jetcat and others. Click 'Radio Control' on their homepage and then 'Jet Engines'. Enjoy
@@joshuagoodsell5952 Jetcat is a good bet buddy. You'd need one putting out at least say 20kg of thrust (200 Newtons - is how they'd be described). You can get other brands - like JetsMunt, King-something, Jet Central.
You're looking at 'model jet turbines'.
That is ABSOLUTELY fantastic!! Enjoyed every minute of this video. Thanks for the entertaining post😁
Haha AWESOME! Thats looks like fun man.. Too bad those engines cost 4 grand.
Great engineering project. That jet engine deserves to be in sturdy Ultralight Airplane. Hight power to weight ratio. Use a lot of fuel but that can be controlled.
First I was thinking you might need two JetCat engines but then I thought about the flight wing and figured that might be too much. But this was awesome! Definitely want to see what the top speed looks like
The moments of force on where the housing is attached to the axel must be absolutely enormous.
That was awesome...however I cannot help but think of "uncontained engine failure" and how one micro-fracture in a turbine fan blade could cause that whole engine to blow apart at the speed of sound... I mean it's great because the metal fragments would rip your brain apart so quick you wouldn't feel anything, but I'd consider welding a nice piece of metal in front of the engine as a "just in case" measure if you're gonna keep this thing. LOL.
What a genius! mechanic, science and engineering plus lot of fun with go-kart!
If you make a aerodynamic capsule just like a "recumbent-bike" you will go even faster lol. Maybe in a future project? :) glad to see that happen.
Plus the wind rushing over it wouldn't be doing insane things.
Just imagine two jet engines mounted?? This was sweet!!
It would be a VERY short drive. It would either end in disaster or you would run out of fuel. One of the above would happen within seconds....
imagine doing that and putting wings and a tail on that
Reminds me when Herman Munster was driving the go-cart he and Grandpa built for Eddie
That was a classic episode, i remember it well, we are giving away our age lol 👍.
I like your knowledge, talent and was excited to see such a crazy project that I have dremt about since I was much younger. I really am amazed at your machined talent and equipment that you use to construct these projects. You are what I wish I could have done with my spare time. Thank you sooooo much for delivering the dreams of many in their youth.
Great project, exciting to watch and imagine. I love the sound of the jet engine. There is just something about that sound that makes kids of all ages just SMILE. Thanks for the dreams.
I would like to see what that would do on a straight run!
Yes!!! That is what I am wondering lol.. Would be so fun.. He needs a runway lol
@@DanielDartez And good life insurance 😏 A go-kart isn't exactly built to be stable at high speeds.
Take it to Bonneville salt flats.
@@eugene9852 i mean everything up to 200kmh wouldnt remotely be a problem. I think that think wouldnt go faster than the chassis can handle. Just needs a decent driver
Dam that jet sure sucks the fuel up! Lmao imagine the cost to keep your tank full if we all drove with jet engines! The price of gas is so high rn! It sucks.
I was think about that..lol.
@@WarpedYT 😂 gas was at a 1$ a liter. now its a $1.20 a liter for regular. N 1.45 for premium! I thank god I have and drive a Chevrolet spark rn! Cheapest car available! But great on fuel! 😂
@@WarpedYT and it drives like a go kart to! It's actually a fun car to drive!
@@sinewave3323 I live in Norway, and the gas here is $2 a liter for regular
@@mastermachineman1462 wow ay! That sucks bro!
Now you need to make 7 more so we can have a real race. You could name this event, Go-Kart Carnage! And each Kart will have special abilities. One could be oil shoots out at the back. Second one could be you drop land mines behind you.😶
I love that winter day light 🕯️
How does it feel when steering, since the jet engine is always trying to push straight forward? Any plans to make the jet pivot (via cables or linkages) when you turn the steering wheel?
Epic idea
Could it drift?
When you think about it though, that’s essentially what a rear wheel drive vehicle is trying to do. Push straight forward and let the front wheels direct it
All you have to do is have an exhaust tube that pivots
@@Trackpad_W4rri0r And a real jet also doesn't pivot the engines. The ailerons are moved to direct the air and turn the aircraft. (And rudders for on the ground).
I could mow my grass so fast with something like this! Sure would like to know what your top speed was, this was amazing! Congratulations on making this!
1: technically that is also an engine. Albeit a jet engine, instead of a piston engine. 😁
2: You know you gotta put an afterburner on it, right? 🤔 Lol
I believe this little guy has a fairly high bypass ratio, so an afterburner wouldn't do much at all for it. Plus you have the added complexity of designing a variable geometry nozzle out of inconel or similar exotic alloy and getting it to pair up with the gas generator so you get the most out of it without choking it too much...that's a whole lotta work man.
@@Skinflaps_Meatslapper As an engineering student, would you mind explaining what a bypass ratio is? Just curious, thanks
@@jb4661 All jets have some degree of bypass, as it's a fuel lean engine (meaning it consumes more air than necessary for the fuel it burns, and that's critical for an afterburner to work). Most jets these days have a first stage fan (sometimes more stages) that allows some air to pass over and around the engine underneath the cowl, rather than being sucked into the rest of the stages, mixed with fuel, and burned. High bypass means a whole lot of the air sucked into the inlet is actually passed over and around the engine rather than being burned. There are also low bypass (most of the bypass air is used for cooling rather than thrust) and zero bypass engines (pure turbojets, which are very inefficient and identified by lots of black smoke), though they're not very efficient and rarely used these days. They were the first jets, and most Korean war era jets didn't have much of any bypass to speak of. Airliners have high bypass turbofans, as well as the A-10, while most military fighters use a mid-bypass design. You get more thrust from an afterburner if you have relatively low bypass, and with high bypass turbofans an afterburner isn't practical since you're developing better thrust using the fans. The reason why it's impractical is that the operational speed is a big determining factor for the bypass ratio...high bypass being subsonic flight, mid bypass for transonic and low supersonic, and low bypass for strictly high speed. Fans become sort of a detriment at at higher speeds (lots of cross sectional area to contend with, compare these to ultra high bypass fans which are basically turboprops), while afterburners become more and more viable to temporarily reach high speeds. Now, there are exceptions for this, but it's all in how the engine was designed. A VCE (variable cycle engine) is sort of the best of both worlds, as it uses bypass air in subsonic and transonic flight for optimal thrust, then it converts that bypass air into a second burner section when in "afterburner" mode, in which fuel is dumped between the bypass fan and a set of power turbines behind it, so you actually harness more of that power for additional thrust. As for the variable geometry nozzle, that's another hurdle to overcome. The nozzle is painstakingly engineered to have the optimal NPR (nozzle pressure ratio) for the best thrust generation over the expected operating conditions and speeds it might see. An afterburner is going to alter that significantly by increasing pressure inside the engine. This could cause a number of issues, from overheating to developing so much pressure that the engine stalls out from too much restriction. That's why you see nozzles on military jets open and close during takeoff and whatnot...they're controlling the NPR on the fly to give the engine what it needs to be most efficient. At full afterburner, the nozzle is open to its limit, designed to be the perfect NPR will all of that extra pressure and flow, but without afterburner, it chokes back down because otherwise you're losing all sorts of thrust. You could design a fixed geometry nozzle to work with an afterburner, but when you're not using it, you won't produce good thrust. The biggest takeaway here is that if the engine was never meant for an afterburner, it's gonna be tough to get one not only to be functional, but worth the effort to do so.
@@Skinflaps_Meatslapper Couldn't have asked for a better response, thankyou!
@@Skinflaps_Meatslapper dude. The internet loves guys like you. Cheers
This was awesome! 😎
This is so insanely cool, I now want one! Maybe a double jet engine cart.
Wouldn't be practical. They eat a lot of fuel.
@@bradleyj.fortner2203 Yeah I know. Still would be cool to have one though.
Looking forward to a second video maybe with a second engine, two would be twice as cool.
Need a baffle in the fuel cell to eliminate the splashing.
Or a true racing fuel cell that has foam in it. They are designed that way for dragsters(high G forces).
If you were trying to make a very slow go cart.......you nailed it.
"I'd like to see that cheeky blue shell catch THIS bad boy!" -crazy jet cart man, probably
Haha
You should find an unused runway or something and just hold the brakes on as fully as you can, rev the engine to 100% and let go of the brakes :D
its a jet engine lol, even without brakes it starts off slow at full throttle
@@chee6916 I am aware but you won’t use much runway whilst spooling up the engine lol 😂 I know this because as a pilot, we have to do that on short runways so we release the brakes with engines already at max power. It means we can utilise as much runway as possible 😌
@@itsjubear Ohh ok, sorry bout that mate, theres only one way to find out tho :p
@@chee6916 Don’t apologise, I was just informing you of my reason 😊
