Obviously there's no point in running an N54 to 7500 with stock turbos or even RB/VTT stock-frame turbos, but if you're running a single turbo or potentially stage 3 VTT's, would the engine have any trouble at 7500 rather than 7200?
If the motor can maintain 400-425 ft-lbs to 7500rpm, that would be ~590rwhp at a very conservative torque figure.
Even if the turbos aren't fully spooled until 4000rpm, 4000-7500 is a very broad power band, particularly if the response above 4000rpm is good.
Seems like all things considered this is a much lower-stress way to make the horsepower rather than trying to run 25psi @ 3000rpm and going for 650 ft-lbs of torque.
Considerations:
This will be slower off the line due to the lack of that 25psi midrange. :) Which is fine with me, I don't drag race anyway.
This will not need such extreme octane/fuel because it's never making over 425ft-lbs of torque (stock turbos make this much easily, even on pump gas. They just don't maintain it to redline.)
Will the motor hold up fine at 7500rpm? Anybody tried it? Any data at all?
Thanks
