Heres a thread from Turbomustangs.com I thought some of you might like to see..It pretty much speaks for itself.
Eric (xlr8) and I went to the dyno today to do some tuning on his car. a brief run down of the setup is my old trick flow track heat intake, same box stock twisted wedge heads, stock cam (retarded 4°), stock block, and 331 cubic inches. the car also has a stock fuel system like mine with 42# injectors. it has a 190 intank and 255 inline. he made the turbo kit and it consists of t3/t4 hybrids - .82 A/R t3's with a T04e 50 trim compressor.
on pump gas and 8.5psi, it made 512rwhp and 626rwtq . we made several other pulls on various boost settings but with a decent bit of C16 mixed in for safety (overkill but still...). at 13psi, it made 601 RWHP and 702 RWTQ . what got me is the air fuel was STILL only 11.5:1 with the stock system and 42's. i figured for sure it would be going pretty lean at that point judging by past numbers on my car with the same stock tank, pickup, lines, and rails. anyways, just goes to show you, don't believe everything you hear about what folks say the stock stuff handles (i've tried to make that point with my car).
we had decided to call it quits at 550rwhp (due to the stock block) not knowing it would make this kind of power at such low boost levels so we went ahead for 600 and got it with only 13psi and did so with a TON of tq. got to love these simple setups...
