Anyone have dyno numbers before and after for the Stillen crank pulley, yet?
I'm still skeptical and don't want to buy any unproven parts because my funds are limited and I'm saving my money for an electric supercharger. ;-)
It makes sense why the underdrive pulley increases dyno numbers, but not the lightened stock diameter pulley. My logic is that if SRM can blip the throttle from 3,000 rpm to 6,000 rpm in under a second, then a 6" pulley with a moderately lower moment of inertia shouldn't significantly alter the ability of the engine to rev from 3,000 rpm to redline over the course of a 25 second, fifth gear dyno pull.
