They get their awesome 1/4 mile speed from launching... once they are rolling they are just about as fast as a stage 3 ZTT. Syclones and Typhoons are like that but more to the extreme... they get great launches and do great in the first 1/8 mile but the second 1/8 mile isn't anything special...(talking stock cars/trucks here). So if you go from a roll at high speeds (50+) you have a good chance if your a modded ZTT when racing a 993 Turbo.
