We actually hired/trained two more people that will be active on the forums for us along with Kent because I may be off doing R&D on new stuff!

While true, you can at least get a good feel for crank HP from a dyno. Our modern Mustangs lose about 12% hp from crank to the wheels with a manual trans and about 15% with an auto.
A better performance indicator is trap speeds from the 1/4 mile timeslips. That is based on pure physics (a known weight moved over a known distance at a known terminal velocity).

Then you have to assume the dyno operator knows what they are doing ( rare ) and what correction factor was used.

The only way to know for sure how much loss you will have from the flywheel to the rear wheels is to compare the same engine run on an engine dyno then a chassis dyno. Even that depends upon getting the engine dyno passes setup as close to what you would see on the chassis dyno as possible (mainly accessories and exhaust). Very few have actually done this (chassis dynos easy to do, plentiful, and cheap to use....engine dynos are none of the above).
The % formula's are a decent first guess, but shouldn't be taken as ground truth.

The whole "15%" thing is a bogus # based on what people GUESS from Dynojets. It is accurate to the tune of +/- 25 hp. If a 50 HP range is "close enough" for you then keep doing the 15% thing.
