I follow Ron Silva and his journey of racing his Demon all over the country. He claims his car is getting faster and faster the more miles and passes he gets on it. I want to say I saw him mention some Demon owners getting together in Gainesville FL over the winter to try and duplicate the factory runs.

I believe Ron's car which is stock other than tires has gone 9.83 in good but not ridiculously good air. So in amazing air I don't see the factory claimed ET to be out of reach. What REALLY amazes me is if they really did that on the factory Nitto tire, it seems ditching those is almost required do get the car to hook at all.

Edit, 9.83@137.xx at 650ft DA, He also ran 140MPH @2500DA.
