I bought a HKS shortram intake, mushroom like, (used) it came with the pipe as well. When i was done installing i drove and during the shifts it makes a echoing sound that has a fartlike buzz in it. i took it apart and redid everthing. I did that about 3 times. finally when i was fed up with it i decided to put back the factory intake (stock). Once i was done, i test drove it AND IT MAKES THAT SOUNDS still. HELP what can it be from
it was not making this sound before i installed the new intake
You are describing the Blow Off Valve. It is releasing the extra pent up pressure from the turbo. Its a wonderful sound because it means your engine and turbo are working right and creating boost. SO put your new intake back on and dont worry about it
