Has anyone tried putting a rotax tripple in a xp chassie?

No, but we can put a Rotax triple in an XP chassis
. Bring it over kid, I got a plan.
. Bring it over kid, I got a plan.Motor could be made to fit without to much trouble I believe...the issue would be the pipes. You have another option other than triple pipes and I think, if im not mistaken, that this is where daves plan comes in
Jake I would love to stuff a Rotax triple in the XP. I still have a soft spot in my heart for them and Tree Basher has one that runs damn hard. I don't think pipes would be too much issue, but I would wonder about the carbs. The engine would sit so low on the bulkhead there wouldn't be a lot of room left for carbs. The 800 twin is obviously cylinder induction and the carbs sit a lot higher than the case reed triple. When the carbs are on the triple engine the float bowls are almost level with the bottom of the crank case. I would like to mock one up to see though. Hell I'm still wanting to drop one in the M-chassis Cat.
I really like the Rotax triples too. They can really rock when right!! But can you make pipes fit and have them not twisted up to the point that they kill the output though?? I read one time that the difference between a straight pipe coming straight out of the motor to a bent up one on a 1000 skidoo was like 35 horsepower. And the difference between how a pipe is bent from a straight pipe to a 1000 stock and how much you would have to twist your already bent triples into an XP could easily be another 20 or 30 horse loss Im thinkin.

My riding buddy is stuffing a 1010 big bore Arctic Cat in his XP and is dealing with the exact same issue as you are talking about. The carbs have no room. Apparently there is a reed block that makes it work though. Ill let ya know when we find out.
For pipes I was thinking more along the lines of a 3 into 1 collector, single pipe and a turbo If you did that then you could roll the motor ahead to incline your case up and fit the carbs to it more easily. Just some ideas.

Good in theory but hard to make a triple turbo run, can be done for sure, but it would likely be easier for the twin or other motor. I think if a guy was to do it, a WC tripple would be what I would try and fit into the XP. That 1010 should be fun though!!!

My idea involves 2 engines cannibalized together to make a triple cylinder reed engine . If we can get some pipes to fit and work we should be in the 200+hp range. All on your dime, we can do it. My money and time = turbo. Cool factor for now would be the turbo for all the attention they are getting now, but after that wears off, I think it would still be cool to see a good old triple rippin' around.

Tree Basher you have a pm (private message). Sent you some ****.
This could be a fun thread to follow if it went forward into production. For sure post pics, it would be a sweet setup!!

Would be tough with the case reed plumbing while maintaining a decent cg.
I would go fuel injection with a plenum and one big throttle body so solve the intake issues. Pipes shouldnt be that tough. think about a 250 dirtbike and the hard 90 the pipes make on those.

I'm with Portgrinder on this one, the FI system would make it so much easier, the injectors could be run farther down on the intake and set almost dead infront of the rotary valve. Then all you need is a simple, even a slide throttle body and a narrow airbox.
Interesting concept, I love the old triples, and one wedged in a lightweight chassis like the xp would be a riot!
Another idea, what if you were to lean the motor forward? Rotate it around the crankshaft axis so that it would bring the carbs up, belt would be the same distance, then you just put a slight extra bend just after the flange on the pipes. Hummm.... sounds like a fun project!

My other advise to Tree Basher today when he was looking at the turbo install, was get rid of the stock chain case and run a Cat Diamond drive for the lack of a jackshaft. Maybe run an older style case that you could run the jackshaft through the bulkhead like the good old days and roll it enough to fit the requirements.
I don't think "we" will tackle this project. I'm sure after Tree Basher dumps the loud flipper on the XP turbo he will see the light. I would try the triple build, but just not enough time for everything. I'm the type of guy to focus on one thing at a time and I don't see a big market for triple XP conversions.

. I would try the triple build, but just not enough time for everything.

A one off triple XP would be cool, but not enough of a market for it compared to T-XP's.
That being said.....I have a big triple if anyone wants to donate an XP chassis to me....

I am surprised that specialty hasnt tried it yet,tilting the motor forward dose sound like a good idea.After looking at the chassie that seems to be the big problem is the carbs clearing.I think someone could do it but you would have to be good.

R+d turbo werx
Oh and by the way Dave,very nice and clean turbo install!

Kinda. Looks like a drag sled set up. Still in the mock up stages? Engine sure sits high. More pictures?
