I just installed my BOOMBA bov and now I see why the boost reference adapter is necessary. The bov is nice and loud, BUT it randomly opens up and starts hissing down the road until you let off the gas. After one day it gets annoying and you want to return to stock. I loved the Boomba bov on the srt4 but not my RS, the random pshhhhhhh noise when your not even shifting is ridiculous.
WHy get a blow off valve though? What is the reasoning behind it besides the noise?
Unfortunately i have no clue what the VTA is. And a google search does not doe justice. lol So really its just the whoosh?The reasoning for getting an aftermarket valve (VTA/VTI/combo) is because the stock one is a cheap rubber piece held in place by a small spring.
The reasoning behind a VTA valve is because whoosh noises.
Edit: Personally, I replaced mine because I plan on keeping the car forever and am 99% sure that the plastic/rubber will degrade over time and many heat cycles.Unfortunately i have no clue what the VTA is. And a google search does not doe justice. lol So really its just the whoosh?
I think I saw the VTI one has like little screws in the middle that you can take out to make it more like a 50/50 setup so you get the vta sound just not as loud?
