Hi just wondering what boost I should aim for. My compression ratio is going to be around 8:5 8:6 and I my aim is for 130bhp.
Thanks

Really depends on your setup, control and usage. But 12-14psi on a T3 would probably get you there.

I think its a T2 not 100% sure as I got it part of a kit with mirage manifold.

Different rolling roads will give different results. They're just pub figures as you rarely operate at the peak BHP anyway. As long as it's fuelled and mapped correctly, and your gearbox isn't made of cheese, you can run around 15psi without any struggles.

Cheese would be an upgrade for the gearbox lol

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will
