Why? Its already been talked about into the ground. Heck, the "What CR for high boost?" thread I started forever ago is STILL being discussed. Nothing is new. High CR, and high boost = There are those that get away with it for a short period of time without problems and they think its a great combo until they end up like everyone else who did it and ended up in a re-build.

whats the difference u'll still end up with the same cylinder pressure..i have 6.0 heads on a stock motor 9.4comp and have to run 12psi to make the same power as a stock head and motor. you have to run good gas at some point..but gas and boost alway end's up as an excuse for somthing

It has only been beat to death with what people "feel" is right and most just follow the norm and dont actually have a boosted setup. The only guys that showed any real world proof were running higher CR and high boost. Only a few people have pushed the limits of their setups and unfortunately most of them are not in this debate because it is ridiculous. I mean look at people that are pushing their srock LS2 and LS1 motors which are high compression. A lot of those numbers are equal to people with 8.5:1 CR motors running lots of boost.
Also the thread title is max boost for compression. Not max longevity for a given compression and boost.

AGAIN, it has already been beaten to death. There are those that think like OhGTO and end up in a re-build (like my former boss who ran only 7#'s of boost through his stock bottom ended LS1 which was intercooled, well tuned, and had a good fuel system and ended up frying a piston at 2500 miles), and there are those that run low CR and high boost and last 100,000+ miles.
