You mean that you were actually able to make a full throttle dragstrip type pass on the chassis dyno?! I never would have thought that any tire would hook up well enough to a full throttle trans brake launch or clutch drop, on a heavy, stationary steel drum, that most chassis dynos use. Thats amazing. I had been told by a local chassis dyno shop that they didn`t like using drag slicks on the rollers, because the tires could get damaged doing so. Supposedly, since drag slicks grow in diameter, and the rear of the car is lashed down with straps, the slicks would see very high loads with the tire growth. One local shop has a chassis dyno that doesn`t use rollers, rather it has flanges that attach directly to the rear axles, via the wheel studs, with the cars wheels removed. With that setup, I would have to think that there could not be any wheelspin or slippage.
I`ve never had any of my cars on a chassis dyno yet, but if there was one in the area that could do a similar dragstrip run, I`d like to see just how close the results were to a real dragstrip, as well as see the relationship between my engine dyno sheets, and the numbers from the chassis dyno.
