home built twin shaft gas turbine kart

This is a video of my bud Dave Rosenlund driving my gas turbine powered gokart. The engine gas producer uses a VT-50 turbocharger coupled to a JFS-100-13a power turbine assembly. The output shaft is run 2.6:1 via chain drive to a jackshaft driving 2 coupled centrifugel clutches which in turn drives the live axle at 6:1 (low speed gear) :). If there is interest shown in this video I have other (night time runs) video showing higher speed runs. Feedback or questions are welcome. Thanks for watching! Bryan Midgley

someone should make a mini turbine (like the ones on the airlines) and put two on a custom cart, if thats what he did i couldent see in the vid.

@piloty5

Turbine (Gas producer) was hand built. Only part of the power turbine section from scavanged from a JFS-100 and was not complete. So no.... no "mini turbines".

Awesome! i hope you don't mind about some questions: 1) Fuel Consumption? 2) Weight of the set of turbines (1st stage / 2nd stage) and all components (except Kart Itself) 3) Have you ever thought using a sort of CVT ? 4) 0-60mph in how many seconds?. Thank you for making this and sharing with us.

@tthhnnee

Fuel consuption is 2.5 MPG. Not exactly a Prius. The engine, including the engine sub frame is about 60 lbs. CVT - yes I have and did develope one. The initial (starting) torque was too high causing the variable pulley to seperate prematurely causing the belt to skip/burn. I tried to dampen the pulley halves but unsuccessfully. On a two stroke (e.g. snowmobile) the power band (peak torque) comes on much later after enguagement. 0-60 est 7-8 secs (with 1 gear.)

This is so freaking cooooooool. Dam! The engine sounds like the BatMobile. Awesome!!!! Does it burn gasoline? Or are you using nitromethane, kerosene, or jetfuel?

[bmidgley]

@jimmykong57 - anything that is fluid and combustable. Used oil and kero 50/50 ratio seems to make her most happy.

@bmidgley Great work! Check out my channel, I've built one almost exactly the same, using an ST-50. If you don't mind sharing, where did you manage to get the power turbine section? All those I've contacted about the jfs-100 parts have said the power turbine is either unavailable, or over $2,500.

Dude, i remeber this. When i next come over. I want to take a video!

JP8 is the jet fuel we use in the F15

Cool concept, but it would be nice to have a video that actually shows what you built. You might look for a semi-skilled videographer. The kart fills about 0.00001% of the frame, and is mostly backlit.
