lol...i like how youre so obviously an engine designer who knows everythiing..as far as the 2 mph thing in 14 years, there is not much to improve on that can get you that much faster than the 250 range without major mods to the engine. and as far as the first super car thing, america hasnt been in the supercar race since the z06 came out, and started beating lambo's, ferraris, and porsches.
and it didnt start beating lambo's ferrari's and porsche's.
the more you post the more i really think you're 14. You do realize cars are more than paper specs right?
