Stop in for a cup of coffee

I didn't realize how much drag is behind the car at high speeds. Enough to make a big difference for sure. and the front end as well.
hp to overcome drag goes up exponentially as speed increases

for example - if it takes 500hp to make your car go 160mph. Then it will take ~ 750hp to go 180mph and 1000hp to go 200mph if the car is unchanged in any aero
