Very nice, you cut the run early too.It want's to pull to 7500rpm from looking at the graph/torque curve.

Actually thats valve float, not John's right foot!!

Just had a lengthy discussion with him and he will be changing up some of the springs and valvetrain components....plus talked him into running methanol as well. This deal will clear 900 RWHP with ease when some of these issues are sorted out.

Insane curve....cant wait till its really dialed in!!

Alot of Meth and the right springs will help alot. I've found on blower cars that is when you hit near 800rwhp you HAVE TO run meth or race gas or the heads WILL lift.

On another note we were running a F1R Stang yesterday on the dyno to 9000rpm.Damn it was loud

WoW....... NICE numbers bro. Thats nuts man i really cant believe 864 at the wheels all on 93 octane. I am kinda really suprised though like you said i would assume mid 700's but 864, thats a lot of hp for no meth or race gas on a 403. Not saying it didnt happen thats just crazy though especially at only 13 psi. All i can say is ls2 owners i think you found your new best bang for your buck set up! Cant wait to see what she does at the track, good luck man!
