If you go to the trouble of going FI than I can't really see the benefit of going beyond 8600. Accept for the fact it may sound pretty cool, why shift the powerband to the right and put that much more strain on everything? I guess the question is what is the purpose of your build? Any particular goals or something?
Good question. Having lots of torque is fun, but it upsets a car that is set up for the track. The car already suffers from wheel spin at higher speeds and I can't even imagine adding another 100 lb ft of torque through a high-boost LC build motor. Given that the motor already likes to rev high...and that the S/C could allow for a continuation of the powerband well beyond 8,600 RPM, it's possible to generate as much peak power. Sort of like an F1 car but of course won't rev that high.

I think the readings are incorrect, but all my 20+ dyno's show between 4.9 and 5.25 pounds of boost. It's the 96mm pulley so it should make 6.0 psi.
