Falls on the 70% line and makes more power on the way to 7K than the other pulley at 7500.. I shift at 7 and have more HP and torque sooner.
I like it and have over 25K miles on this set up. All based off a dyno tune done at Z1 on another car with a 88mm pulley making 517 RWHP boost at 11 PSI.
current set up, GTM 1.5 kit 750cc injectors and some day digital NOS.
