Something different Building for MPG.

I've noticed after trying about 6 different calculators that there are two distinct fomrulas being used. One that IMO is stingy, and one that seems to jive with the Moroso slide rules that always proved so accurrate at the track. Not surprising because it's just math and what order of operations is used can affect the outcome. One can only conclude that somewhere in the middle it the true output. I typically use the Moparts calculator because for my car, and several others, the results match the chassis dyno results we got. Or are at least within say 10hp of the result. The Wallace one (and the other similar "stingy ones" are coming up 60hp lower than the chassis dyno results. That's a little off IMO. In any event, Dave (dgc333) has always been a very straight shooter and not a grandstander. His car does run that well.
