With all of this talk about classification of various cars, if they are classed right, if they should be moved etc. I got interested in how cars are classed from the beginning. Then, I saw a few blurbs in GRM about NASA's system and was wondering how it works.

It appears that NASA classes cars based on weight and hp, at least in their V8 series. So, a minimum lb/hp and the hp is checked with a chassis dyno. Furthermore, apparently they can pull a car at any time and chassis dyno it on the spot to catch cheating.

This seems like a neat system in that basically do what you like but you must remain in the safety rules and you must meet the class hp/weight restrictions.

Anyone know if this works well and how they manage, or if they manage, to have a dyno at events to police things? Obviously, I don't know much about this but found it interesting in that at least there were hard and fast formulas that could be applied to classify cars and also to eliminate cheaters.
