Not very fast from a roll. I had one messing with me on the highway earlier, he wouldn't stop riding my bumper. Finally he gets up next to me, doing about 70-75ish. He floors it, I was ready for him as I had it in 3rd already. I walked him pretty good, let out at 140 and he was about 4 or 5 cars back. I assume it was stock, and I heard it downshift so it was an auto too. Not very exciting, but I think I did alright. Mods in sig
