Anchor2,
I can't answer your question positively, but I have a couple of friends who race Daytonas and they have 700+ horsepower engines in them. Both told me when I asked that they had been as high as 182 and maybe if they had a long enough straight stretch and enough nerve their cars might hit the 200 mark. I think for a street version that is actually driveable on the street to hit 200 would be a stretch. I am not saying they won't do it, but I don't think I would want to be driving the car if it does do it.
