it would be a saleen 351 (351 windsor engine + supercharger). they run like a 12.0@~122. saleen also does a lot of suspension mods. there are also saleen 281 and 281 supercharged (like the other guys have mentioned), but they arent all that quick.
his could also be a fake saleen; a lot of people like to get the body kits and pretend that they're saleens.
