support mods needed to run Big 16g @17psi

[turbonawd]

is a 190lph fuel pump good enough to turn up the boost to 17psi?

or would I need 550s and safc also?


I'm only boosting 8-9 psi right now and I can barely hear the bov or the turbo spooling. Is this because I'm only boosting this much? It used to be louder with the T25 @12psi (stock boost).


will it get louder once I hit 17-18psi ??

I don't know about louder but it will be faster.

Your bow off valve if it's the stock one will not hold 17 psi.

Thats right. If you are still using the stock CBV, you wont be able to achieve 17psi. With an upgraded valve, you may get away with 17psi. But I would say 15-16 to play it safe, until you can get injectors.
