The ideal placement for AFM (Air Flow Meter)
The AFM (Air Flow Meter also known as a MAF Sensor) may cause a few problems if it is placed too close to your turbo. But this is also related to how much boost you are running and what your BOV(Blow Off Valve) is rated to handle with regards to boost levels.If your BOV is unable to vent/release the back pressure caused from deceleration, then the turbo will be forced to turn back to allow the air to escape. When this happens, turbulence is created infront of the turbo and when the AFM is extremely close to the turbo, incorrect measures maybe made by the AFM. However this would only really be for a split second.
However – if your BOV isn’t up to the job and even if your AFM isn’t close to the turbo it is important to get a BOV to suit your boost levels. The life of your turbo will be directly related to this – forcing the turbo to spin in the opposite direction at high revs put alot of unnecessary stress on your turbo.
