Yeah 500rwhp is not terribly hard to get. Of course you'll have to use at least drag radials like bernie pointed out. And remember its all about the driver. The race is over pretty much in the first 60'. Check with Gyro he will give you the recipe for 500rwhp...you don't have to use the jwt turbos. His car also dynoe over 500 to the wheels on stock motor. Sparkie actually made a little less and still ran 12 flats with traction problems I believe.
: is still a question on if it will get in the 12's?
