Doing 208 in a Mustang, not believing that.

For sure, mods could produce enough horsepower, but it would be very expensive, and where did the 19-year old kid get that kind of money?

Then there’s the problem of aerodynamics. I’m pretty sure the 200+ mph Hennessey Mustang (seen of ‘Jay Leno’s Garage’) has aerodynamic mods. There is HUGE aero difference between 170 mph and 208!
