Wing Inactive Members 1 Member For: 11y 8m 16d Posted 25/09/13 10:40 AM Share Posted 25/09/13 10:40 AM Hey guys this is my first post here!Today I installed a Process West street air intake to my FG xr6t, When I'm driving I can hear it sucking in air quite loud but as soon as I let go the throttle it causes a loud whistle sound like air pressure! My mate thinks it's turbo back surge but I had no idea just an intake could cause it, everything on the car is stock including computer.Is this sound normal, good/bad and how I can resolve it?

The intake noise potential is not in the same league as exhaust but up there nonetheless.To resolve, return to stock.

Since I lowered my boost to about 16psi I get less of it. I think it's just all the turbulance from the air flow in hitting the turbo wheel as the butterfly shuts and the pressurised air in the intercooler has to go somewhere.It was a lot worse when I had a stronger BOV or no BOV. Now I am back to the standard BOV which seems to work fine and make less back pressure/surges.CheersChris Link to comment https://www.fordxr6turbo.com/forum/topic/86356-new-air-intake-causing-surge-like-sounds/#findComment-1430062 Share on other sites More sharing options...
