I am not trying to sound like I have all the answers on this subject cause that is not true. I am facinated by engines and tuning challenges. I have been onvolved with forced induction engines (mostly turbos) for over 25 years. So, please do not take my earlier posts wrong. I learn as much from you guys as anybody. But the net is a source of truth, half truth and totally wrong statements, lol. Sometimes it is tough to sort the real information from all of the chaff.

My original post was only to point out that when determining the maximum allowable BMEP for any engine, it is not the same for N/A vs forced induction and even then it also depends on what the engine application is to be. Formula 1 or NASCAR or top fuel engines limits are not really applicable to street cars which we hope to drive for several years even if not a full throttle all the time. We should strive to keep more safety factor in our limits unless we want to be buying lots of expensive engine parts.
