Not necessarily......the Cobra just needs a little more help in the suspension, drive train and traction department. The guy that sold me my blower made a little over 550rwhp with his Whipple blown 3,900lb, 4R70W equipped, fully loaded, full weight T-Bird and ran 10.8X@127mph. He’s since dropped the pulley size a little and has run a best of 10.5@130mph. ....That was in a boat of a T-Bird, not a Cobra. Getting the power to the ground seems to be the Cobra’s problem, not making enough of it.
