@@LogieT2K My ASS!! All my 2020 GTI has is (APR intake, turbo inlet, turbo muffler delete, Forge BOV). Turbo flutter starts around 15psi, and sounds oohh soo sexy. I was surprised at how controllable the sound is, makes the car a one-note musical instrument. Drive light and granny it, it's barely heard. Dog it out a little, massive flutter and hiss. An excellent addition for driver/car familiarity and engagement. As for drops in boost, it's barely noticeable. Kinda like the car is, WITHOUT a BOV on it 😉

Question is, iam interested in adding a BOV, should i? the only reason why i wanna do this is the psssshhhhh sound hehe. If i do, will this affect my fuel economy? The existing setup has the recirculating thing iam sure. Please share your thoughts. Thank you.

@T5_T-Rell 5 жыл бұрын
a correctly functioning blow off valve only opens when the throttle plate is closed and you lift off the gas....it doesn't bleed off boost or cause boost to take longer to build up. It just relieves the built up boost once the throttle plate is closed.

Is it normal to hear a little bit of air being released from the blow off valve while cruising at higher RPMs? If I'm driving on the freeway and am in or near my power band, I can hear a little bit of air coming out before shifting. Also, if I am going wide open throttle from second to third, I don't here any BOV noise until the RPM's drop down and I'm getting on it again. I just bought a modified 135i and am new to the turbo world. Not sure what is normal and not. Car is running great and putting down appropriate dyno numbers.
