400-450whp should be able to get an STI or evo fairly close to 180mph in the standing mile, in the quarter they are already at 125=130 or higher I'd imagine. 190 probably took some work, 550whp+ I'd bet.
24xmph on the busa is no joke Ben, especially in 1 mile. What does a stock busa run in the standing mile, 170-180 or so? I can't really tell from the picture, are you turbocharged or just running 6 gallons of nitrous a run?
