Wow!I watch the Goodyear formula drift event recently and one word.....AWESOME! the sound from Mad Mike's FD that is.It sound just like a superbike and i heard it's a merge or 2 13Bs.And on full throttle....orgasmic.
Have a myvi with BOT using YRVT manifold, turbo, intercooler etc.. it comes with this bosch pbv, the vacuum hose runs back to the intake manifold but somehow when boosting even as low as 0.1bar i hear a whoooshh...
Can anyone advice me on this matter? I’m not sure will it make my car lose horsepower or not. I myself once experienced the power loss of changing 4” outlet...
