Hey Tim,
What boost will you need to run to get this power ??
I'm guessing 6 to 8 psi ?
Thereabouts, probably peak around 10 depending on how much timing it gets in it. Knock isn't really a concern so much as peak combustion pressures. I'm not too fussed if it's a bit lower - lower is safer, not stressing the motor so badly until the new one is assembled.
