Well I upgraded to a VR4 Supercharger (1500cfm @ 14psi):D :D :D
What a PITA, but its finally done.
I had to change to a 8rib belt setup and a 4inch Intake setup,
and find a place to mount the BIG A$$ filter (round 7in X 14in) that would flow 1500cfm.
Now need to start some tuning.
BTW it blows the spark out at 12psi, had to regap the plugs to .030 so I could get over 12psi and 6000rpm out of the motor.
Check the Classifieds for my old parts that are for sale.
have pics of old stuff there.
