Bogged the motor way down! Called Scott from competition products. Gave him all our specs and dyno sheet. Got an 8" PTC with 5600 stall now. Told him Jake drives the car to school everyday. He said shouldn't be a problem. We want the 9 sec run also. We had other issues besides. I think we have corrected them all. We are looking for a 9.87-9.93 @ 137 mph run out of his car. We will know soon. Good luck!

Steve- if your peak torque is 5400, that's around where the stall should be. Ours was 5600 peak torque & 6900 peak hp.

That thing is fast.

My car is very similar but 3700 lbs. still got full interior, power windows, power antenna and 4 mufflers. My buddy said it was one of the quietest cars going down the track.
