I posed this question in the GT500 tech section, equal drivers, and stock to stock. I think it will be a drivers race, but a dude in the other section thinks the saleen will get dusted by the shelby. I think not. As a matter of fact, I think the saleen is just as quick if not quicker with 5lbs of boost, and a 4.6 vs 8lbs of boost and a 5.4. Of course this is all based on the magazine #s I have seen. They say 0-60 in 4.5 to 4.9. 4.9? with 500hp? The 300 horse GT does that. 1/4 in 12.2 (by evan smith), to 13.1 in C&D. I have a new SC saleen and of course am partial, but am buying a shelby also. What do you saleen guys think?
