I remember on the BMWs i use to run the light weigh crank pully would gian you about 3-5whp as the udnerdrive would gian you 5-9whp
Both are safe. As long as you dont underdrive the crnak and run a lightweight flywheel. Its all good from there

www.kjrperformance.com has a dyno before and after with the KJR on it. You can expect approximatley 8 hp to the wheels with this pulley. Stock pulley weight is 6.4 lbs and the KJR is 2.02 lbs
