X2. Say you have the typical 330-340 cfm E- head out there available from a lot of people.
13.5 psi of boost will make 850 hp on a very basic 455 type engine. Luhn Performance proved that deal.
Many Years ago there was a guy named Doug Hess who ran 8.40s with his heavy Camero with a 350 cid engine. Article by Woody Hatten in Super Stock magazine.
So Doug put a single dominator on a new car (Monza body - same engine) and TURNED UP THE BOOST and ran well into the high 7s. HE WAS RUNNING TWIN TURBOS SO THAT WAS EASY TO DO. many years later, as you said v869tr6, that still is the way to make big hp, and not so much on the cid and head flow side of the deal. Only reason why you need the head flow is if the class restricts boost and engine displacement.
