It made 654rwhp on a cold pull with the 9.06” lower pulley. They are now replacing the lower pulley with a 9.65”. 625 seems a little low.

I guess 680 on the first pull in the morning. 650 or less after that.

I have Jannetty Terminator Cam, same headers, no cats, only a 8.650 lower/stock upper, JMS voltage booster, but a 95mm throttle body with a big gulp and put down 690 whp on a nice hot Florida day.
But I was also on E40. What fuel are you running? I would wager 650-660 range |
