this usually works for me on the corky--
(written for analog)
--at the top of the hill, just before you lose traction from the jump, tap the brakes twice, under 120mph.
--brake to 53mph.
--take the turn rolling, very little acceleration.
--halfway down the screwer, begin turning slowly.
--3/4 of the way down, floor it in a car with less than 400hp, half-gas otherwise. turn almost all the way.
--at the bottom of the turn, floor it. (you may need to correct some oversteer.)
