I will say that my BBX fukin RIPS at 33psi but I really really don't want to push it so ~30 is all it'll see I think, I want to keep it together and healthy for a long time.

Well this time I will make a TON more at say 30psi as I now have 2.2L and 10:1 compression coming. I was honestly planning to run around 25-26psi and see where that gets me. I just wanted the external gate on the downpipe for if, probably when, I want to go crazy on E98 and max the setup out.
I am now a member of the I want a car that works for a long time and I can more or less beat up because I am not on the ragged edge.

Hmm, well my internal gates wastegate pressure is 21-22psi so i am guessing I want at least that. I'll have to consult with Shane.
