2. Accufab throttle body

3. BBK cold air kit

4. 2.93 (4) Lbs pulley

5.Predator tune for pulley

6. Aux idler (100MM) and the two (90MM) idler replacments

Dave~ I have similar mods (Borla exhaust, BBK twin throttle, MAC cold air, pulley, flash tune, etc.) and I'm around 460hp/430trq at the rear wheels. So at the crank (given an ~10-12% drive train loss) you're looking at over 500hp. Best bet is to get the car dyno'd and see what numbers you make.
