Ive got hooker long tubes, 3 inch y pipe, flowmaster muffler catback 3 inch. LT4 hot cam kit, Electric water pump, cold air intake, all free mods, deleted the power steering and all accessories. BBK underdrive crank pulley (aluminum). I am getting custom dyno tuning done on the car right now, shes a 93 with an auto. Wondering what this car should put down on the dyno?

 

Is the car an auto or M6? I would guess that with the mods you have done you would produce around 320 RWHP if there is not any head work done. Add about 5% to that if you have an M6. But let us know when you get the #'s!
