620 was the highest I have seen, actually it was 619, there are however numerous cars that are pulling 600-610s rwhp. It really is amazing and I suspect Ford under-rated this car a bit. These cars are also trapping as high as 127 mph stock in cool weather, which backs up the dyno numbers. I think it's safe to assume that the 500 is producing every bit of it's advertised hp and then some.
