The lingenfelter would smoke the 800tt. Here are the facts. lingenfelter henessy 0-60 1.4sec. 2.4 0-100 4.3sec. n/a 1/4 mile 9.2sec. 1/4mile 9.99sec. topspeed 240 or higher 230 So there you go. By the way if you think my 0-60 facts are wrong on the lingenfelter, go to lingenfelter.com and see for your self. On motor trend they said it was 1.9sec., but they also said that they had regular street tires on not grippy tires. I'd like to see a jap. car do that. Jap cars don't suck they just aren't as good as american cars. American cars are by far supirior to jap. cars,but jap. cars don't suck.
