Cool Vmax 4, not 2 or 4 stroke...

THATS CRAZY!

I'm going to ask what everyone else wants to know: how much? And does it have electric start and reverse?

 

[steiner]

That's a lot of downforce on the front end.

does it have electric start

Hittade faktan på nätet. Facts Jetpower is built on a 1992 chassis from V-MAX Yamaha where the staff re-assembled the engine, fuel tank, control system, and instrument panel. We founded the name JET because we have installed a jet turbine engine from a helicopter. The engine is an Allison C 20 and performs at approximately 400-450 hp depending on temperature of the engine which can vary between 700 - 800 Celsius (1292 - 1472 F). Fuel and oil tanks are built together in 3 sections where fuel volume is 21 litter (5.54 gal), hydraulic oil 42 litters (11.1 gal) and engine oil 4.3 litters (1.13 gal). The power from the engine and hydraulic system controls together from a thumb handle which is on the original location of the snowmobile, through three regulators which is calculated between the different functions fuel control, governor and hydrovalve. The instrument panel exposes with an amp meter for turbine wheel N1-N2, temperature meter, engines temperature and hydraulic-pressure which can reach pressures of 500 bar. To handle all strains on a very high power level and high speed It claims very high quality on material and oils.

Cute......all show no go? Any video of it on a lake? Trail? Moving other then a parking lot?

Seems to idle high.

I would love to see it flying across the lake.

This sled was built in 1997 (i worked there when it was built) and has just been started again after years in storage.
This weekend is "Snowmobile day" in Northern Sweden so all dealers show all their sleds and accessories.
Nice to se it still works, i hope they will drive it and put up some videos.

Looks heavy!
Hahaha you knew that was coming.

 

[dmaxx]

Still to0 heavy and darts all over the place.

Where did you get a gearing reduction unit that could be used for a snowmobile?
I gather wound up that turbine would be spinning at +/-20,000 rpm. To gear that down would be a major challenge.

I have read in the Abram tanks the gearing reduction unit is physically much larger than the actual turbine engine that powers it.

Impressive. I bet the 21 litres of fuel goes quick. Being around some helicopters those engines are thirsty.

Great work.

Definitely post a clean run across a lake this winter , would love to see it.

Needs a 156 for the mountain and maybe we can talk cash.

That thing is sweet!
