[QUOTE="Bad Company, post: 15367110, member: 141815"] You're 100% correct. Now here is the only thing that I can think of that would make a difference if SC RPM stay the same for both pulley combinations, with the exact same drive ratios on the same engine. 1) both the lower and upper pulleys would be larger in diameter with an OD lower and a larger diameter upper for the same Supercharger pulley drive ratio 2)with both pulleys being larger in diameter for the same drive ratio. Each pulley has more of the SC belt surface area to contact around the circumference of both pulleys. 3)with each pulley having more surface contact around the circumference of each pulley with the drive belt. The chance of belt slippage goes down significantly. Especially while trying to accelerate the engine at full throttle in the lower gears of the transmission. Where the engine's RPM rate of acceleration per second increases significantly. The less SC belt slippage as the engine RPM sweeps through the engine RPM range, the more Hp and torque produced for the same exact SC pulley drive ratio. [/QUOTE]
