Message	are capable of 220mph with their 750HP if allowed to go top end. But an F1 car should be able to do 240mph with about the same HP . Anybody verify this? I was an Indy time trial back in '91. The top car/drivers were doing around 225mph for qualifying. But this is on 2.5 mile oval that has no steep banks like a Nascar track to keep it planted. Recently in the news, this local guy claims he did 219mph (speedometer) in his Lamborghini LP640 on You tube. Wikipedia puts the top end of that car at 211mph. Some maganzine articles testing a Lamborghini not sure of the model but could not break 200mph. "Yes, I know more then JWT. Someone has to be the top dog, and it just so happens it's me." Nixit
