I haven't seen anyone running, or needing to run an aftermarket clutch on their 800.

Has nobody reached the limit? Is 60-70 horse the max you guys are running on these? Is that at the wheels or a guess at the crank?

I've seen the pictures of broken pistons. The broken ring lands look pretty typical of a detonation issue, not necessarily power output. Anyone running any timing control? What kind of total timing are you running at WOT? Is everyone just running premium fuel? (As opposed to race gas or E85, but seeing the lack of fuel control I don't see E85 as a feasible option just yet, at least on fuel injected models)

I bought Mike's (Gundog) LJ Tech 800. Drove it around in front of my house and decided I should probably turbo it before I take it to the dunes. Runs just fine, I just don't have a lot of fun in stock Rhinos/RZRs;) Hopefully it will be back together and maybe to the dyno by tomorrow afternoon.

How could you NOT have a fun in a RZR?
There are so many mods that can be done to them..

I did say stock;) They are all fun, but if I can double my power fairly easily, I don't see why not. I just don't know what roadblocks I might find trying to get this thing where I want it. If I've gotta be the first one to huff a rod out the side of the block, then so be it:)

WEST COAST (a member on this forum) is down in OR and very good with the 800cc engines and turbos. I do not think he ever had trouble with a clutch, but he has blown out third gear in the transmission. Send him a PM or email and see what he can do for you.

I'll get ahold of him. I don't really need anything, just information that may or may not exist. The third gear breakage is a perfect example. Was that on a stock clutch or an aftermarket ceramic disc? How and when did it break? The middle of a pull or right after shifting when the tranny wasn't loaded? Those are the types of questions I'm looking to have answered.

I was hoping this thread would eventually be a good source of information for everyone, pms don't spread information very well;)
