I believe Greg studies each car and keeps a database of stock whp dyno figures for cars that he gives a dyno reclass to. I would think at this point the Dynojet whp of a stock F20 and F22 has been pretty well established.

Properly performed Dynojet runs should be within 1% from dyno to dyno, and that is why NASA uses it as their standard. If you can find a Dynojet that seems to read lower, then by all means go dyno your car there before you submit your dyno forms for your reclass.

Greg has some formula only he knows about for the weight, so there is no good in trying to guess. It doesn't follow the published power to weight ratios for the classes as he has some sort of modifier. The best thing to do is to just get the dyno done as early as possible and send the data to Greg. Then just react to whatever weight he provides.

The reclass I ran at Nationals in 2012 and at some events in the 2013 season was 215hp @2770 lbs, TTC base class. If anything, he's added more weight to the cars since then to try and even them out. I haven't applied for a dyno reclass for this season yet.
