You guys will get a kick out of this. Most of my bigger power customers we put on a chassis dyno because of traction issues / having to do pulls at such high speeds so the tires dont spin. This is a car with a decent size turbo and you can really see here how each pound of boost can really add on the power. it was tuned for peak power at 26psi and peak at 38psi. 26 psi the car went 142mph (evo8) in the 1/4mile.
just to show with the right data and the right road you can have good dyno info to compare with.
