Jet Turbine Golf Cart Onboard Video

You might be able to use the stub output spline that came with the engine and have a shaft welded on by a good machine shop.  For the oil system, you'll need two electric pumps and two oil coolers. The pumps should suck oil out of the gearboxes through the drain hole and return the oil to the fill hole. I used a Tilton differential cooler pump from summit racing on the power turbine and a small electric fuel pump for the gas generator section since the power turbine gets a lot more heat.

Thanks and I'll let you know how I made out..you are very creative!

I bought a jfs 100 300 starts and would like to put it in a project too. I'll have to modify the throttle ..I guess...it does have the factory plunger throttle though. I got to get a shaft made from someone.somewhere? Any ideas about increasing the oil system?....I seen all your jfs videos so I can learn...Thanks for the info...it's very helpful and we appreciate it very very much...look foward to more projects and keep up the fantastic work!!

I was worried about the turbine wheel and now I see that you made all the safety measures...

If you check out my other videos, there's one of the engine being run on the test stand before I installed it on the cart, and you can see the output shaft well. Also, glad you liked the other video when I blew by my buddy on the other cart. That's my favorite part of the video too.

The engine does have an overhaul schedule based on the number of starts. The engine was 1/3 of the way to this when I got it, and I think it will take me a long time to get to that number. As long as the turbine is not subjected to excessive heat or speed, exploding turbine wheels should not be a problem, and the engine is run at lower speed in this application than on the airplane. I did add a 5/16 armor plate blast shield under the seat in the event that an engine failure did ever occcur.

The air clutch is a six-disc industrial clutch from Logan clutch. It looks similar to a clutch pack inside an automatic transmission. The clutch is engaged using 100 psi air pressure which is stored in the bottle on the back of the cart. There is a small electric air compressor inside the cart body which keeps the bottle pumped up. I bought the output shaft from a machine shop which had made them for someone else using the JFS-100 engine for a go-kart project.

also Joe, How did you make a shaft to engage the planetary transmission? is there any worry with total starts for these engines ..as to exploding turbine wheels for running on ground projects..thermal cycling? you can tell I like these lil engines..thanks

Thank you for the information.....I got everything but what the air clutch is. I'll tell you ..the video that shows you blowing by the camera and other golf cart made us laugh so hard ...I fell off my chair! =)

Thanks! The digital gauges are from Red Lion Controls. CUB5 digital counters for the N1 and N2 percent and the speedometer, and a CUB5TC thermocouple gauge for the exhaust gas temperature. Power is taken off the free turbine's output shaft and transmitted to the wheels through an air clutch and 520 size motorcycle chain turning a differential on the rear axle through a 2:1 reduction obtained by sprocket sizes. There is an 18.3:1 planetary gear reduction inside the engine.

really cool project...where do the digital gauges come from and how did you connect the power to the pavement?
