I ran this aero recommended setup and it works very well. I actually moved to a slightly lighter pri spring and liked it even better. not sure the exact #'s on spring. I got 2200kms out of the belt before it started to fray. that's at 10 lbs boost. had a paragon on the last sled and ended up taking it off. my friend who talked me into the paragon also took his off. we both had different issues.The P-85 is a viable setup. I think Ken typically runs a P-85 and Paragon clutch. At Aerocharger we've had really good luck with the Ski-Doo clutches running stock ramps, 200/290 primary spring and a completely stock secondary. We typically also change the gearing, going up to a 21 or 22 tooth top gear.
