I bought the gfb and put it on 50/50. I have a 4eat WRX. I cant even hear this thing at all. Ill floor it and the auto will shift on its own and no sound whatsoever. Only way i get sound is if i put it in neutral or park and rev then i can hear it vent. Car runs great and turbo actually spools faster since the install. But i want the noise damnit. Im thinking 100%. Any suggestions?
Doesn't look like anybody paid attention to this one, but since you're automatic and keep your foot to the floor during shifts, you will never hear the BOV. As far as I can remember from DSM's, the BOV opens when the air in the intake goes from boost to vacuum....which only happens when you take your foot off the gas and close the throttle plate. That's what BOV's were meant for....when closing the throttle plate, the boost has somewhere to vent instead of backing up and trying to spin the turbo in the other direction. That's why you only hear it when you're in park or neutral and revving.
