On my 92 pump tune I have zero problems making, and holding about 10.5-11psi with zero creep on the BOV/MAC, And 13psi with zero creep on my E40 tune which is used 99.9% of the time after tuning the 92 pump tune. The BOV was loud when off throttle and at 2.5k+ rpm, so I made a silencer can’t even hear BOV now except immediately off throttle at high rpm, and also routes the air opposite side of filter, possibly helps temps overall not dumping hot charge air all over everything

I have a g37 so a little different possibly but I got a 90 degree elbow and routed the filter behind the front grill right above the intercooler. l get all that direct cool air.
I have zero IAT/charge temp/heat soak issues, coolant issues etc… doing multiple high speed pulls back to back in hot weather.

I routed the exhaust from the BOV to dump under the car but it is still pretty noisy. What is the silencer you mention?

I've considered using the brake duct cutouts on my front bumper to allow additional direct cooler air flow to the filter..

So far no overheating issues on my setup.

I got a 1.5" to 2" coupler to put on the end of the BOV, then a 2" to 2" coupler joint, then a 2" to 2.5" 180 degree elbow. then got a 2" ID PVC pipe approx 9" long, that goes inside the end of the 180degree elbow, capped the end of it. Drilled about 120 or so 1/4 holes in it (none aiming down at the IC), Got some 3" length x 2.6" OD with a 0.8" OD internal hole aquarium sponge filter that I stuffed inside the pvc pipe and then ran some zip ties through to keep them in place. and then I placed a 6.5" KN cone filter over the exposed end of the PVC to clean up the appearance and keep debris/water etc... off of it.

Now I honestly forget it even has a BOV. Probably 80% quieter vs without. Before it was so noisy and annoying in typical city driving, sounded like a jet 24/7.

I got some pictures up on the G forums someplace.
