If 370inj, top out at 12PSI on the BB, then why can RWD DET's run 1 bar boost on 370's???

from what I know they don't top out but they're running at a real high rate maybe around 90 % one thing wrong and I don't think I'd risk it, even though when I get my ECU I probably will anyway...oh yeah one question you replied in my Blow off valve question, what kind of noise does it make phssst...or what my friend put a volvo bov on his 13B turbo on his RX-2 and it whistles pretty funny when there are girls walking and he shift...

psssssssshhhhhhhh!!!!!!!!!!:D
