GT45?! lol! 25psi with a single GT40 is somewhere in the neighborhood of 700whp on my engine! Then a GT35 will enable it to put down mid 500's at a reliable boost level.

I'm good with a GT30 reaching full boost under 2,800 rpm's and still putting down 400whp around 1 bar then maybe run 1.5 at the strip if I have the tires.
