Blower pulley questions....

I'm going to call ATI monday, get info from then and then call ASP to have the pullies made...

I just want to get an idea of what I'm going to have to ask them...

The motor setup will be a 372c.i. 9:1 compression motor...w/the ATI D-1SC procharger on top of it...

I will be running on pump gas, I got enough fuel to support it so thats why I want to shoot for about 12psi for a nice street setup...

Now I've heard that you want to max out the RPM's of the blower, so different pully sizes will achieve the certian amount of boost?

I'm going to run a 7.85" crank pully (8 rib), but I'm not sure as to what size blower pully I'm going to need to run..

Anyone have a lot of experience on this stuff that can give some insight on all of this...

Thanks,
Bos

Re: Blower pulley questions....

dude I told you to get to about 2,000 rpm from the max because that is where the blower is the most efficiant. I also told you to call and talk to sergio or matt or jeremy or eric at ATI and they will tell you what size to get. You cant base it on boost because you have no idea what your loss will be with your motor. On my motor a 14 psi pulley only made 7 psi of boost. so go by rpm of the blower not boost level.
