I just installed a FMIC and 2" piping with a turbo xs bypass valve. It is recirculated. Now Im hearing a loud whistle, sounds like the turbo spooling up. It only happens when boosting while in the petal. Is this normal? I just want to make sure nothing is wrong. Also my boost seems low. I was boosting 7-9 with the top mount intercooler. now Im boosting 6-6.5. Maybe I need to drive it to let the ecm relearn??????? Thanks for any input..

well, Im hitting about 2 psi less at most. It is a cheaper intercooler. Maybe its restricted in the intercooler. I am pretty sure the whistle is the turbo spooling up. I did notice that when Im approaching 0 psi when its pulling out of vacuum it whistles. Or the bov is allowing blowby because the spring is too weak. Ill try swapping it with a stiffer spring since I know someone with one handy.
Is there any way you can trick the wastegate on the 3sgte? I know on the single turbo supra by putting a stack of washers between the wastegate and the turbo you could increase boost. I think the setup of the 3sgte is different. |
