half-bridge motor with a t67 turbo. 96 a/r turbine housing with a 3in vband but Im a pretty sure the downpipe gets smaller to around 2.75-2.5 till the apexi catback which is 80mm.
Question is would this cause boost pressure to be high without making alot of power?
I have high comp rotors and it seems to have high boost pressure(25psi) without making that much power(330 rwhp).
