Hi I got a 2006 REV 800 (150hp) with a broken motor and got an crazy idea to replace the engine with a gas turbine. I need some advice on what type of engine will fit my build the best, its a bit cramped in the engine bay as you can see.  I have around 40-50cm in length to work with and maybe a diameter of 25-30cm if I place the gas turbine in the same directon as the old engine.  If i place the engine with the intake facing forward, the engine can be longer but then i have problem with the steering colum.   Any thoughts on this project? I will get better photos and get more measurements. (sry for bad english) / Tommy |

Hi Tommy, there are lots of options out there, just depends on budget and if you want to build an engine or repurpose something else?
Cheers Ian...

Hi Ian I haven't set any budget yet, but of course i want it to be as "cheap" as possible. It will be a long project if I decide to go forward with this and collect parts over time. I have been looking on the web for a APU or something similar but haven't found anyone. What type of APU or similar engine is around 150-200shp and pretty light and doesn't cost 10k++? I do not own all the necessary equipment (lathe/milling machine and so on) and skills to build my own engine right know, maybe in the future. If I want around 150-200shp on a DIY gas turbine, will the size be around the same as Johansson got in his bike? / Tommy |

Hi Tommy!
An interesting project idea, there were some guys here in Sweden who fitted a Rolls Royce Allison helicopter engine in a Yamaha Vmax-4 chassis. I read about it in an old snowmobile magazine and their biggest problem was getting the power from the engine to the driveshaft.
They used a hydraulic system with a large oil tank to solve this, not pretty but it worked.
There aren´t many gas turbine engines in the 150-200hp power range available, and probably fewer still that can be considered cheap. That it one of the reasons (besides the fact that I enjoy building things) I built the engine myself for the landspeed motorcycle, another reason is that an APU would be way to bulky to fit inside a bike frame and probably a REV chassis as well...
I hope I haven´t dropped a turd on your birthday cake, just trying to point out the possible difficulties. If you can find a suitable engine then you are halfway there, hopefully someone here have an idea where to find one.
Cheers!
/Anders

My recomendation cause i Have My Hands On Both a gtp30-67 an a boeing Power turbine..
gtp would be harder to get to work because it is stuck in size an Shape of How It works.
a Boeing Power turbine would Be Easier To Manipulate in To Position.
but you would still Need To Figure Out A Turbocharger Turbine Build To Power The Boeing Power Turbine.. an The Sub Systems.
Like oil an Fuel systems.
the Gtp 30-67 on ebay Is Not Complete engine.. i Wouldnt Buy it if You want A Simple build Its Missing A Crucial Part The Fuel Governing Pump.
an i Know the Guy Decently Well Who Has The Boeing Power turbines on Ebay Trans Turbine
they are Good Pieces An would Be Ideal I think Because You Can Manipulate Your Build To Fit Better in Your Situation.
BUT You Would Still Need To Buy A Good Sized Turbo To Make a 100 hp.

Cheers! /Anders Interesting, you know what magazine? i have tried to google it but finding nothing. The power transfer will be little tricky but with angel gears and little fantasy I think its possible. I don't see difficulties, I see solutions  I need to draw up the engine bay in Inventor so I can see exactly how much room I got. Hope someone here have an idea where to find a suitable engine for this build. Hi Mark Yes i'm looking on Ebay every day, nothing there will get me aroused at the moment  My recomendation cause i Have My Hands On Both a gtp30-67 an a boeing Power turbine.. gtp would be harder to get to work because it is stuck in size an Shape of How It works. a Boeing Power turbine would Be Easier To Manipulate in To Position. but you would still Need To Figure Out A Turbocharger Turbine Build To Power The Boeing Power Turbine.. an The Sub Systems.

BUT You Would Still Need To Buy A Good Sized Turbo To Make a 100 hp. I think the 502 is way to big to fit in its original state, where can I find measurements on the 502 engine? drawings 2D? 3D? / Tommy |

This idea is a non-starter. Stop while you are ahead. Not enough room, and wouldn't be fun or practical.

Hi Tommy, Keep looking mate something will come up, as for that GTP- 30-67 that should be Ok to use  he has a vid of it running. You need to sit down and think how often will use the sled for or is it a experiment Owning a turbine engine is expensive. As for the Boeing Power turbine unit the output shaft spins anticlockwise as i have one and using it in my next project. Cheers, Mark. |

Yes i will keep looking, meanwhile I will draw up my own turbine engine. I will maybe use the sled 2-3times a year in a straight line. |

Ah, so it will be a drag race sled? If so another option might be a hydrogen peroxide rocket powered steam turbine, an idea I´ve been toying with for a couple of years but never gotten around to actually build.  |

Yes, a drag sled but want it to look as stock as possible from the outside. H2O2 steam turbine isnt a bad idea, crazy amount of power guessing it will be hard on the drivetrain.... |

Then I think a turbine engine isn´t really ideal, it´ll be cool no doubt about it but it will most likely be the slowest sled at the drag race. At least with a turbine engine small enough that it fits a REV chassis.  |

I think its a bit to dangerous for me and the spectators if something happens. Yes, a drag sled but want it to look as stock as possible from the outside.

At least with a turbine engine small enough that it fits a REV chassis. Tired of the ordinary piston engines, the sled has been on the track (hillclimbs) with the pro 800cc engine I got. If I put a turbine in it, I will be racing 1mile races instead. If I take away the "look as stock", then i can take away the gastank and build a new seat. Then I can put for example a 10/94 engine backwards under the seat and the gearbox/oil/gastank etc will be placed in the engine bay. / Tommy |
