To put in perspective, back in 1969-1970, it took 620HP in a Dodge Daytona (which was very aerodynamic for 1970) to go 200mph and now it only takes ~450hp to go 200mph in a latest NASCAR speedway cup car.

Jay, the aero only matters on the road course it's not really a factor on the auto-x or speed stop.
