ASP Pulley Question I finally got my ASP pulley installed on my M6 2002 WS6 and I had few questions. The car revs way better then it was before. Its like I have got much better low end now.
The two questions I have are that
1) When I take it to redline in 1st gear and then shift to 2nd, it feels as if the pulley was revving too fast and as I come into second, the rpm hardly falls like when it fell when I has stock pulley. Its like from 6K rpm in 1st it goes down to 5200 when I hit 2nd. Although that is good but do u guys with ASP pulley feel the same thing that tpm does not dop as much comaperd to stock pulley when shifting WOT from 1st to 2nd?
2) Also, howcome ASP pulley gives more hp....it only allows u to rev faster and get into rpm/powerband faster?
Thanks,
Adnan K

Re: ASP Pulley Question An underdrive pulley essentially slows down the rate of travel of the serpentine belt. This results in slower turning accessories, and thus, less drag on the crank. The net result is a reduction in the amount of parasitic losses caused by the accessory load.
The reason your revs don't fall off as quickly is because the belt is experiencing less drag. This is definitely a good thing. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
