F1A

I think he just means compressor curve, which is probably right but not what I really meant to ask.

At the end of the day I'm only looking for 800-850 at the wheels with a gt350 and I am not sure if the faster ratio will fatten the mid range, or if it will just introduce more parasitic loss.

My D1 made 644 / 532 with a 4.10 pulley at 12 pounds of boost. This was a 6 rib stage 1 kit.

My F1A made 736 / 580 on 15 pounds with a 4.75 pulley and stage 2 8 rib kit.

This was on 93 octane, ID1000's and a boost a pump.

If anything a steeper ratio on the blower will allow the motor to overcome the drag of the blower by seeing boost earlier.
