Well, in reference to the Mustang hp@50 (air resistance in HP to maintain 50mph... rises in resistance as a cube to speed) and vehicle weight, we *could* datalog a car in a gear (say 4th, since thats what Martix dynos in generally) on the road, and then try and repeat that curve by varying the dyno parameters. Then everyone could agree (heh... I know I know... I said "agree") to use those Mustang parameters in PPB.
Then everyone could then agree to forgo "flywheel estimate" numbers, and leave correction factors out other than to mention the temperature in the room.
OR, one tuner wiht alot of marketplace weight could begin by stating the hp@50 and vehicle weight (as a constant) and making all of their promotional "output" the same. Then maybe they could drag the community/marketplace along with them?
Wouldnt that be... hypothetically great?
