Racergo I would not bet that there is a whole lot more in AA/GL, maybe FL. We are running up against the aero wall with the frontal area size it takes to get over 500 cu in. Supposedly Seth has around 1050-1100 on gas I had around 930 one is going to have to get the total drag down as well as the frontal area--- I have not seen anyone doing all at the same time. I sure haven't, I have done some but not all.
