ahhh, finally got the spec sheets and trim sizes on all the Squires Turbo/STS systems....average power and torque increase is 40-70% at only 5 to 7psi (non-intercooled).

Trying to compare displacement and everything between the applications to determine what would work best on a 540i's M62 4.4L V8?! Intercool it and increase the power another 15-20%(guessimate from their numbers/dyno tests)
On paper it looks good anyways?! [I think] feasibly a 50-60% power increase could be made on a stock engine with 6 to 7psi...sure, i'd be happy with 450hp/500lb.-ft. torqueBUT If the engine was mildly built maybe 10-12psi with 550-600hp?
