I know the pp-SHO will go 140 stock because of the speed limiter. With LMS tune they remove the limiter so aerodynamics are the limiting factor. Does anyone know what the top speed would be with a tune? I tested the car in Forza 4 which is supposed to simulate stuff pretty good and with ~430 cHP it could hit about 180. Do you think the car would fall apart at that speed? Is it faster/slower than that? Just curious to see how the game correlates to real life (without maxing my car out on the road).
