BOV no noise?
BOV no noise? not trying to be a ricer... but i have a rps 50mm bov with the smaller spring installed and i can see it open but i still have compressor surge and it makes 0 noise....
i have it mounted right b4 my intercooler and have it referance at the same spot as the wastegate.
where is my problem?
thanks

You want your waste gate to know what the boost pressure is in the manifold no where else. Manifold pressure is the only pressure that matters. Taking a pressure line off the turbo or anywhere other then the manifold can give an incorrect reading to the waste gate till it catches up. If you take it from the manifold the waste gate can stay closed longer and reduce boost lag while giving it the most accurate pressure to do its job. Manifold pressure is the only pressure that matters. There is an area of high pressure before the huge restriction you call an intercooler between the turbo and the intercooler. that area does not matter one bit. It could be at 42 psi it doesnt matter as long as the manifold pressure is at the pressure you want it at which is why you take the pressure line from the manifold.

Iv used 3 different wastegates from 2 different companies and not a single one of them has caused a vacuum leak. Then again i didnt buy junk ones either. turbonetics and turbosmart. Both good gates no leaks. It would be pretty stupid if it did leak then it would be bleeding off boost. Thats not good.

Not true...Many setups reference the wastegate at the port on the compressor housing or between the intercooler and the throttle blade. This eliminates excess heat from the fact that your compressor is not compressing as you say to "42 PSI" for no reason. At 42 PSI the charge temps skyrocket and that heat would still enter the motor even if you were only seeing half that actual pressure in the manifold itself. You can reference your wastegate from at the compressor, before the throttle blade or after the throttle blade with three different results, not one of them wrong. BOV on the other hand must be referenced somewhere in the manifold between throttle blade and intake valve.
Like he said it might work but i dont think it is the typical way to hook it up. leave your BOV ref. to the manifold, "between the throttle blade and the intake valve. ref. your waste-gate to the compressor side of the turbo, right to the compressor will have the fastest response, but you can also ref. it anywhere between the compressor up to the throttle blade, i have found you will see a boost spike the further away you go from the compressor, delays the valve from opening.
