Popping Sound Shifting Under Acceleration

christian370z

I was actually following your thread, I bet the car will feel a lot better with your upgraded heat exchanger and a little boost! I meant the 928 impeller, a member was selling a Stillen SC kit and had the blower modified and was making great power.

I'm just wondering why that popping decided to happen all of a sudden, and it happens when shifting quickly between any gear. It also is very loud and sounds like it comes right from the driver's footwell, it's just one loud pop like a speaker popping. Shifting a little more slowly at WOT does not produce this sound.
