This is the link to ski-doo where you can view the specs for your sled. Ski-doo. Ski-doo claims peak H.P. at 7850 rpm.
I have a 2002 mxz 800 and I run my max rpm's at 7900 - 8000. With the B.A.M. performance head kit, V-Force III Reeds and Reed spacers (a total kit I purchased from a local dealer here in Canada) the kit came with specs and dyno tests to show that my sled will now produce 152 h.p.(compared to the 135 stock hp)
So I also installed a heel clicker clutch kit and customized the weights, because I am now producing 135 hp at 7000 rpm, I have tuned the primary to run my sled at around 6000 rpm at 1/2 throttle, 7000 at 3/4 throttle and 7900 - 8000 at full.
It performs great when I squeeze the throttle and demand the power. This weight combination has allowed me to get extremely great fuel milage with my 800. The friends I ride with who have 600's and some older 650's cannot believe that if I ride with them at their speed (NOT full throttle down the lake for me to stay beside them) that I actually use slightly less fuel than they do.
Running a clutch setup to stay in the peak power band most of the time is alot of fun, however be prepared to pay at the gas pump for it.
