Message	additional horsepower does it take to go from 200mph to 220mph? I am guestimating it will be an additional 200hp to get the extra 20mph. This is for a car that has drag coeiffiecent similar to our cars, corvette, Lamborghini. "Yes, I know more then JWT. Someone has to be the top dog, and it just so happens it's me." Nixit
