Granted, you have to beef up the tranny, and learn how to tune the stock compression pistons; but let's be honest - 10 or 11 to 1 is begging for a super or turbo charger. The reason people generally say you can't run high boost on the stock engine is because there are a lot more crappy tuners out there than there are good ones.

I have seen several well-tuned cars running 7+ psi break ring lands. In my mind, it's just a matter of time on stock pistons. My personal observation is that it takes about a year of daily driving for them to break.
