Hey guys I was wondering where I can order a smaller pulley for my supercharger? I have read that whipple only makes down to 3.25", I was curious as to what psi that is equivalent to, I was looking for around 12-14 psi, about what size of pulley would I need? I also heard that asp makes pulleys but I cant seem to find them on their site, do I just call instead? thanks guys, I know they are alot of question and ive been searching but cant seem to find an exact answer... once again thanks in advance

call whipple. they will hook you up

 

southflorida is a good bet.. terry gets right back on ur emails and get things sent out the same time you pay.. great service!

 

I have a 2-3/8" pulley on mine. So they make'm smaller for sure.

 

Its cool to pulley down for alittle more power but consider changing the inlet and intercooling.I will be posting some results of my setup soon once the bugs are worked out..
Blow through+intercooled+redesigned inlet for 90mm throttle body+2.9 pulley=17psi real fast and cool.

 

what do you mean by blow through? interested in hearing more about this setup.

 

Like blower blows through the maf.I moved it to help with restrictions in the system.It has a blow off valve now.Unfortunatly it is too small.This thing builds boost like a radix on roids.
