Ok, so I have a history of being a little happy on the gas and a little early on the clutch during all-out acceleration. That said, I did it in my 06 zx3 and there was this huge "boom" that sounded like it came from under the hood. It does this every time. Anyone else experiance this. And please, no comments on my shifting, I know, it needs work, used to a saturn, just got this thing. Anyway, could this be the motor mounts completely collapsing? It doesn't sound like wheel chirp. Wheel hop? All I can say is it's reall loud, and I had some people listen to it and they agreed that it was alarmingly loud.
