Are the pulleys you get with the kit are they the best because unorthdox racing sells a pulley for supercharged applications and is there anything higher than the 11psi pulley jackson racing sells.

I'd use the Jackson 4 inch blower pulley & the MVM stepper pulley. Jim has both of them @ Motorvations Motorsports. Give him a call @ 205-661-3600.

For what motor? The stock Jackson pulley for a D series is 3.8". Endyne sells a 3.25" which brings things up to 9psi. I wanted to do 10/11psi and the guys at Endyne suggested I don't do it without modifying the blower. Sadly Unorthodox doesn't sell an overdrive pulley for the D. Just an underdrive.
