My first question to anyone is... Is there about a 20% drop difference from flywheel to rwhp on our 05 mustang GTs? If so, then would these blowers, non-intercooled, claiming 420rwhp feasibly be considered 500+hp cars and top the upcoming shelby's 475hp? I'm only thinkin of not intercooling my engine b/c I won't be forging my internals, and I still want reliability in my daily driver (also save a little extra $ for body parts and paint). Third question... anybody hear any diffrences (quality, performance, etc) in the paxton v. vortech? All I saw was that the paxton wa running 38 lb injectors and the vortech runs 39 lb. Anything else I should consider? Thanks fellow tang lovers!
