To quote Tom Turner, who has been racing forever and has a lot of insight of race car packages, he explains it very well on his post:

I thought the J Allen Sherman thread had ended but evidently not. On that thread, there was a fairly detailed discussion over a heads up race the J Allen lost (dumped). If you do the arithmetic; on the incremental s, he was on a high 9.80 pass. I think he can go as fast as he wants.....maybe into the 70's in good air. We will have to ask Billy but I know of no other team that is even in the same zip-code. This is a very stout effort; all HP factors aside. I will be surprised if he shows it all at Indy but I will bet you will see some of it....right up to the time for pictures.
