Could anybody tell me how much bhp per psi the stock fd twin turbo's deliver?



Cheers

From what I've read, it's about 6% per psi. So, 255 HP @ 10 psi would be about 60 HP more @ 14 psi. == 315 HP



That may seem a bit much, but assuming you have the DP, MP, and CATBACK to handle the flow, it's probably close to that.

Much appreciated, asked this question many times in the UK forums to no avail!
