Might I suggest our 76mm Clutched pulley



or the 83mm clutched pulley

with the 76mm pulley I would recommend the Stage 2 cooling kit
and wether you decide to go 83mm or stay stock I recommend at least the stage 1 cooling kit. (updated bosch pump and split cooling)

Just out of curiosity, how does the 76 compare to the 77mm? I know you guys used to sell the 77mm. Just as safe as the 77mm? Comparable tunes? How much difference does .04" really make? Haha

the 76mm is equivalent to the 168-83 stack, so just one step up from the 77. 14.6 vs 14.4 lbs of boost. when stacked with a 168 the 76mm will give you similar boost levels to our 70mm clutched. so we just wanted to stream line combos across all of the upper pulleys. the pulley steps before were rather random.

168+83=76
168+76=70

OP PM me and we will get you setup

Boost is only a measure of restriction and will differ from car to car depending on the modifications.

Never thought I'd say this. But I agree with you
