I was pulling 9 psi very strong that day with excellent weather and low humidity. I would say the power was 280 FWHP if not more that day. With quaife and slicks you should pull good sixty foots and result in even better 1/4 times. My 1/8th mile was 9.2 @ 81 MPH.
I did later put Nitto drag radials on the car with my stock drivetrain and grenaded the stock dif, stripped half shafts, and grenaded the tranny. So Quaife is a deffinite safety if you don't want to fork over $3,000.
