Joe, I was wondering on my way home.....could this theory be true:
When I had the highest topspeed reading, was when my friend was slipstreaming me with his Porsche 911, in two or three other occasions the readind was approx. 10km/h lower, could it be so that BOTH cars have benefit of such a slipstreming?
My theory is based on that fact that a car has two air-related things to deal with, one is in the "front" , wedging the air with the sum of frontarea*cw , and the other is the "vacuum" cone and turbulence BEHIND the car..... Suppose now that someone "takes ower" that rear force from you (the car behind) , the result is that instead of 2 cars with 4 forces to deal with its 2 cars with only two forces......it would result in a higher speed for BOTH cars..!
I'm I totally lost in space...or...???
