Truthfully it sounded like I had sucked something in and damaged the turbine blades, would boost uneven and was very high pitched almost whistle like. I bought a 2G gsx Eclipse with a damaged compressor wheel that had a very similar noise just not the uneven boosting(by uneven I mean it would boost up then while in boost drop off a bit then back up all while the pedal did not move)......The Mazda tech said he had seen this before and new exactly what the problem was, sure enough the compressor housing had a small crack that leaked into the cold side and also slowly leaked out and down. The shaft had been super heated and warped causing a unbalanced state and the compressor wheel under high boost would rub slightly thus causing it to catch and give the uneven boost. It was f...ed. Glad it did not self disstruct and make its way in the intake:eek:
Talking about these cars and trying to figure them out is the only way things are gonna progress.
