Contour Enthusiasts Group Archives Forums Modifications Duratec Performance 70 MM Throttle body.

I know I promised to stay out of this thread, but I feel compelled to touch on this latest topic.

The fact that Duttweiler used the stock TB is irrelevant. Aside from forged rods/pistons and a mild cleanup of the heads, the Duratec used in the "Beast" Focus was, for all practical purposes, a stock mechanicals SVT longblock. Assuming that the stock TB is good enough for that application is like saying that the stock SVT cams are ideal for turbo applications since they didn't do a custom grind.

BTW, Demon, I realize that you only mentioned this as a "FWIW" side-note and nothing more.
