coolxr6t New Member 8 Member For: 7y 4m 15d Posted 26/11/20 04:50 AM Share Posted 26/11/20 04:50 AM Hey guys, I have a turbo side intake installed on my fg. I like the intake noise, but not so much the loud turbo flutter from taking the bov off. Can anyone recommend a blow off valve I can install in place of where the old one was that isn't too loud. Or if I can somehow use the factory bov. I don't want it too loud if that's possible. Thanks Link to comment Share on other sites More sharing options...

Any 25mm BOV can work depending on whether you want it to vent or recirculate but the stock one is fine if you don't want to spend the money. 1 Link to comment Share on other sites More sharing options...

(green = hose, blue = BOV) I'm using a GFB Deceptor Pro adjustable BOV but the stock one will connect up just fine in the same spot 1 Link to comment Share on other sites More sharing options...

Some change the sound (make it louder or high/low pitched etc) but they're all designed to be noisy if they change the sound, so the likely quietest is the stock BOV Link to comment Share on other sites More sharing options...

It doesn't sound to obnoxious at all really. Definitely nothing like a ricey one. I'm running about 15psi and seems to work fine for now. Not sure if it's even legal here in NZ but I don't really give a crap. The alternative tu tu tu tu tu tu sound is not for me. Plumbing back to the inlet with turbo side intake is not the look I want either, to much hose! Link to comment Share on other sites More sharing options...
