[QUOTE="mlambert, post: 1816533, member: 23120"] Well the only thing I can tell you is that you're completely wrong. Forced induction is forced induction is forced induction when it comes to manifold pressure. The reason I state that 1.21 is used for NA cars is that is what dyno shops use for NA cars in high elevation (normally its anything from 1.22 to 1.28, way too high and results in inflated numbers and :bs: from newbies). They adjust for ambient temperature but not manifold pressure. A good rule of thumb floating around the 'net is 1.087 times the raw numbers for forced induction (if boost pressure is around 1 bar) and 1.175 for NA. It's still all synthetic though and the raw numbers are the real numbers you should be using as a baseline. If you're concerned about what kinda power your vehicle would make at sea level, go to a track at sea level and find out. [/QUOTE]
