Default CRANK PULLEY

Anybody have any dyno numbers or e.t. reductions/mph increases with the use of an ASP or similar crank pulley?

From what I have seen, .08-.10 in the 1/4 seems around the norm. Maybe someone who has timeslips could confirm this

CHP put an ASP pulley on a lightly modded 99 Z and gained 7 rwhp so I would say you would gain maybe a tenth at best
