I'll take a stab: 295/310 wheel with those mods. But for reals, unless you have emmissions concerns, I'd go O/R on that exhaust. Wakes 'em up!

I really want to get into a dyno shop, just havent had time yet.
NO EXCUSES!!! get over to the dyno and get it on there!!!


I JUST ran mine on the dyno today, about four hours ago. Stone cold stock.

Run 1: 90 degrees, 49.98% humidity and 30.08 in Hg
276.10 rwhp at 5,700
272.38 rwtq at 4,300
A/F was a little fat, running from 14.18 at 3G's to 12.04 at peak torque and 12.27 at peak HP to 11.84 at 6,400

Run 2: 88 degrees (?), 49.91% humidity and 30.08 in Hg
277.71 rwhp at 5,600
295.57 rwtq at 4,500 (somebody explain THAT to me!)
A/F was still a little fat, running from 14.00 at 3,000 to 11.93 at peak torque and 12.32 at peak HP to 11.71 at 6,300

So in round numbers, 278/296 at the wheel on a hot, humid day. All in all, I'm well pleased with these numbers as a baseline.
