He said that sure weight has something to do with it, but wasn't clean on exactly how it effects the car. I still believe that running down a track will produce more power than comapred to a dyno.

I'll agree with you about the cooler air but that is also dependant on the conditions. A pull down the track in June or July may not yeild better results than a dyno pull in December.
