1.62 on DRs and a stock motor. Our low 12 second GT40P car runs the same 60's off the rev limiter on slicks... Do tell more, thats a HELL of a 60'. Best I ever saw out of that type of set up was middle 1.6s on an ET Street, and the car was a 12.7-12.8 stock motor car!
ive cut a couple 1.8s on MTs stock suspension launchin at a conservative 3500rpm, bolt ons and 180k motor. Hopin to change that with some work this season.
