Hello all its been a while. My truck is running good but Like most I want more!!! First ? is does anyone use the Asp pulley on a SC motor? I would thing that if I put one on it would decrease my boost. The other is I already have a B&M
shift kit. Do you still use a servo or what? the truck bangs 2nd gear hard as a rock now. Any other mod recommendations would be good too. thanks all!

An ASP pulley will really slow down your blower. Since the ASP is 25% under off the crank your blower will go that much slower.

So... take your blower pulley size and multiply by .25 and get how much smaller you pulley will need to be. i.e. 3" pulley x .25 = .75. Then 3"-.75" = you will need a 2.25" blower pulley.

At least that I was I think should be done to compensate! lol.
