I hear a lot of excitement about the PT method of classing cars, but let's face it -- once a national championship is on the line (this year), people are going to start taking those races much more seriously, and then NASA is going to have a serious problem with policing those classes. How is anyone to really know if a competitor's car is classed properly, when basically an infinite number of modifications might be made to it?
Same thing with the power-to-weight classes. I can bring a dyno sheet, but who says my car is in the same configuration as it was when it produced that dyno sheet?
Neither of these classing strategies meets the bar of being enforceable, and as such, are really only going to work for "recreational" racers who don't much care about winning and losing. But NASA seems to be trying to go head-to-head with the SCCA with the addition of their national championship, and it would seem they are headed for an internal collision if it turns out that someday, winning a NASA National Championship holds any significant value.

VERY well put. When the PT thing first came out, I said it was a nightmare of epic proportions trying to figure out WHICH mods worked on WHICH cars that "beat the curve" and which mods didn't work on which cars....finding the right combo, or sweet spot was a challenge of nightmare proportions, and probably needed a Cray supercomputer, (plus a lot of hard data) to spit out a definitive answer.
Then....once you have the answer, and buy the right car, and put the right mods on it, you then need to figure out IF the other guy is telling all, and you need to determine if he should be as fast as he is, with the mods he claims. Of course, you might have no way to know what mods he has!!!
Jeeeez...just typing it makes my head spin!
A cheaters paradise, and an enforcement nightmare.
The dyno thing is interesting, but when it comes right down to it, using a dyno to enforce class equity is a very difficult task. Very difficult.
However, NASAs PT class is genius in that it gives the HPDE guy an immediate place to race, while demanding nothing from him in terms of prep. No matter what he's done, there's a place to play.
Sooner or later, it will dawn on some that there is still a magic combination that "beats the system" better than other combinations, but for the guy looking to step up and get his feet wet in wheel to wheel racing, its a great next step.
