I have the CRV pulley to give me 10psi for my JRSC gsr, but where do you guys recommend I get the stepper pulley? Unorthodox makes an alternator pulley for supercharged cars(and also meant for cars with added accessories like subs), will that be good or do I need to go through Jackson Racing? Thanks for your help.

 

I got mine through Jackson, Endyn might offer something also.

 

I would go through Jim @ Motorvations Motorsports in AL.
