Our little engine is proving to be far more robust than I would have guessed. The only engine failures I have read about were due to mechanical over-revs due to improper downshifting in race like situations. I have read about our engines being tuned to rev to over 7.5K with moderate boost pressure with the stock compression ratio of 10.5:1 and (separately) handling the abuse of autocross without complaint.

I am curious if the 3a92 has a weak point. Not sure if I am wording this correctly but I am curious where our engines are likely to fail in stock form?
