APBA legal need to check? Will not give a speed advantage ;-)

Awaiting results. I assume you will have a test on stock engine up to standards made on the new dyno to compare broke in +20 and +30 to and note all tune differences? Will you convert all results to same standard base conditions for relative comparisons?

Yes they are additive in the X direction components and they are additive in the Y direction components.
Based on water vs air density at 80F at sea level the water is about 840 times more dense that air so all else being the same water drag is 840 x more than air drag.

Very aware of air and water drag components and density difference of air and water. And of course at the speeds stock boats go water drag is way more important due to the density difference relative to air. In my example above #41.1 I was only focused on water drag (should have stated...

Interesting approach with several of the many variables.

That formula is derived from the drag relation of Drag (Force) proportional to V ^2 and it follows that Power being proportional to Force x V results in Power proportional to V^2 x V or V^3.

If Power...
