With nothing more than a stock 301 Pontiac(with beefy block), a mild .350 lift cam, 250 gross duration, crappy crappy heads with 1.75in/1.5in valves, a very poor designed turbo compressor outlet, a way too small turbo, 2.25in single exhaust, a total of 24 degrees mech timing, a 800 CFM Q-jet , and a old pellet tpe catalytic could make 210 hp. And with minor mods (K&N, but stock ar cleaner), upped timing (mech and initial) and cat removed, (yes, a pellet type) cold make 290 rear wheel hp with only 7.5 psi boost, imagine what can happen to a properly setup Cadillac 300 CID V8?!?!?!?Originally Posted by illumina
Heck, even an improperly one can make 300 hp easy!!!
Turbos respond to mods very well, sorta like a multiplier not just an adder!
