Does anyone know much boost the 2.5 engine can safely handle?

Really, I mean if you have proper fueling and cooling, you can probably hit pretty high (assuming you deal with fuel cut out at 14 psi(1 bar)). With say an MBC I wouldn't run more than 9-10 psi. The problem with adding more boost like that is fueling. You run the engine lean which is bad. At extended amounts of time that can be very bad. So a little is fine.
