Dyno & Bench Racing Forum - New intake hp guesses?

I put down 404rwhp n/a with my g5x3 and an LS6 intake w/ported TB. I'm picking up my new ported FAST92/92 combo tomorrow night and getting it installed this week. How much you think I'll gain seeing as how I'm still on stock heads? You think I can hit 420rwhp n/a with the ported FAST92/92?

My guess, 412 rwhp. It all really depends on how much of a restriction the ls6 intake/throttle body was for your setup.

Good luck.
