1150 CPC clutching??

[Phat Cat]

Me and a friend put a CPC 1150 in his Kingcat chassis. He has CPC pipes and Carbs. He is running a 162 X 2.5 X 15 track. We ride between 5000 and 8000 feet in BC. Does anyone know of both primary and secondary clutching that works well for this set up? Any help would be appreciated!!!
Thanks, Scott

You should never clutch for claimed HP. Clutch for actual HP your sled will work much better.

REALLY I thought that common knowledge. I ask this and then take real world numbers into affect.

Hey MDS,
It has high compression domes in it. They clain 225 hp at 8200 RPM.
Thanks

69-70 grams, yellow white cat primary spring. 47-49 degree helix with red/white cutler spring or the green snopro cat spring in the secondary. That should get you awfully close depending if the motor has been ported or not. You might need a few extra grams for running it from 5-8K feet, maybe try 71's.

I ran 78s with my 1160 at 6-9000 ft.

Yep LHF, you are the fastest bestest everrrrr. Anyways, I ran 69's in my lowly 1150 at 7-10K with those springs and a straight 49 helix. Ran hard, shifted nicely and kept the belt pretty cool. So unless you have the fastest, lightest, most horsepowerest, turbo slaying sled on the planet like LHF here, that should get you pretty close.

I sure am glad I didnt buy an 1150.

I sure am glad I'm not a tool like you.

Yeah I could put a helix/spring set up in it that could pull 100 gram weights... or on the other end a set up that had 40 gram weights in it, and the sled would not even pull 6 grand... the weights are arbitrary to the helix/spring set up.

Cant believe I even wasted the time to get into this....
