it doesn't sound bad per se.. centrifugal blowers can sound anywhere from a high pitched whine to virtually silent.. a lot of it depends on the cut of the drive gears. Straight cut gears provide more noise than helical...

considering the location and size of the procharger, I wouldn't say it sounds wrong... but only procharger could say for sure.

other than that, your idle seems to be really uneven. is that just a tune issue?

[edit] meford has a point, but I would need to see how quickly mine shuts down to say for sure.... [/edit]
