Well that seems to be a delicate subject on a couple of other boards I frequent, but with a good tune I will be dissapointed if it puts down less than 370 RWHP, 420 RWT and runs slower than 12.20's. Thats with a 2800 stall in a 700R4 A4. The key will be the intake, not sure if it will support the heads.
It made 300 RWHP and 360ish RWT with an A/F ratio over 15 / 1 with the last settup. I am swapping out the old Twisted Wedge Trick Flow's for a set of AFR 195's and the old Crane Cam HR 276-2S-12 IG, .488I, .509E, 214I , 222E will be replaced with a new Comp HR, 112 spread, 108 intake centerline, I .567I, E.584, 224I, 230E duration.
