To me it seems that the 3 most cost effective ways to even things up
are weight,restricting induction and tires. Weight is pretty easy as 5 lbs. = 5 lbs. In Ca ,Spec Sprints must weigh 1700 lbs, so many teams use steel for floor pans,side panels,motor plates, ect. Not only cost effective but likely safer as well. Induction is a little tougher. As Mr. Moore stated, testing would have to be done and there is the rub. There would be a lot at stake for the motor builders and some (or all) might be inclined to slip in a detuned unit for said test. I ain't sayin' ....... I'm just sayn':2:. So, if a particular Engine Builder was a major series sponsor.......uhh. Which brings us to the biggest political Football in Motorsports, Tires. Believe it or not the MG-7.8 came about because of BCRA. I was on the Board in 2002 and we found out that WMRA was running the MG-8.0 as their Spec R/R. It was hard and had good repatability with most teams getting 2-3 programs on it. As I recall, the 8.0 was no longer being produced so at the 2002 Promoters Workshop in Reno, BCRA, USAC and Hoosier got together and came up with the 7.8. From our perspective, the tire did it's job with the difference in lap times between the top cars and the lower dollar teams shrinking. Having said that, just because there is a number stamped on a Tire, that is no guarantee that all Tires are equal. I will leave it at that except my opinion is that the only numbers that matter come from a durometer and the number of "winds" (nylon/rayon) .inside the tire.
