I have a highly modified Grand Prix GTP that has never seen a dyno until yesterday and I was pleased with the results. I made 389 wheel horse power and 376 torque of of just a little 3800 V6. BTW I just use M1 5w30 lol.
Why are you only showing from 4500rpm up? My 135 makes full torque at 1200RPM. I'd think yours would be real stout down low. We're not looking at Hondas here.

There it is ladies and gents. Good MPH.
Yes, and that is a pretty quick e.t. as well for a HEAVY, powerful FWD ride as well, and WHY I was asking what diff (as well as what half shafts to quell the torque steer) he has in it to get those results.
