Didn't you and Jim both try that already? :D

Ha, yea. Over 11,000 didn't work so well.

I was kinda disappointed. Several "what if's" and no real world horsepower curve data for any specific engine. As far as a performance engine goes, the 4G63/4's are still in their infancy on a large scale. I'm sure the bigger name guys like Buschur, Shepard, etc., have their engine programs in full swing, but for some reason it doesn't seem like much of it has trickled down to the masses.

I don't think Buschur has any real tricks up his sleeve, he never made that much horsepower. John and Brent definitely have some tricks though.

It's called methanol and 60psi of boost.

It's not as simple as throwing boost and methanol at an engine. Shepard has an engine program that is trying new things, very successfully I might add, and overcoming the pitfalls along the way. The part that's even more amazing is he's doing it with a manual transmission when most DSM's can't even get out of the 10's with 600/700 horsepower at the wheels.
