Thanks for the reply! Are you using an Aster bracket? And is your bracket braced at the bottom? If my car ever makes it back from the dead, I'm going to try to make an 8 rib work on an F1R with this pulley. We'll see....

Any other Procharger guys make the switch? Bob, I'm sure you've sold a few. Have you heard about the results?

I'm already maxing out the D1SC with a 7.65/3.40" combo, or else I'd jump on the pulley and run it. I might anyways to get max rpm out of the blower earlier.

Wish there was a 10 or 12 rib option out there to run a F1R or X on our cars.

Procharger has 62,000 listed as the max speed, my math has you 2k rpm short so if you go to a 8.65" crank with a 3.7" blower has you at 62,303 blower rpm at 6,500. So more boost with more blower pulley belt wrap, and you could shift at a lower engine rpm too. Come on you know you want too

7.65" / 3.4" * 4.1 (internal step up ratio) * rpm (6,500 engine rpm's) is 59,962 rpm.

8.65" / 3.7" * 4.1 * 6,500 = 62,303 blower rpm
