even though you're making less power than the mp62's with the 3.0 pulleys, you'll still be out of fuel in the 6000-7000 rpm range, especially with the higher boost.

CX- I tend to agree... in fact, you're most certainly correct... I'm pulling it off with 440s, but I'm really pushing the envelope for them. To keep the duty cycle within acceptable levels and still leave a little room, 550s are probably a certainty. I'm doing a fuel system test here shortly playing with the stock fuel pump, 440s and 550s, which is why I even mentioned the 440s as being a possibility---even if a remote one
