This car did very well. This Whipple is the one that uses the stock throttle body. I really think that the stock throttle body is holdinging it back. We have seen stock vs single blade on these Whipples and the ones with the single blade make about 20hp more. This one made 628hp 621tq, but yet not to bad for 93 octane.
