I know you are right.I have lived through it myself.Only one small thing is,and if you have a tach you can see it,when you are running flat out it pulls you down going up a hill and you loose some RPMS,going down the other side you will gain some RPMS.It would be hard to keep a constant speed unless you were on flat ground like the salt flats.So the ones talking about a speedometer have a point in that its not perfect,but your calculations are better than a speedometer if you have a tach.Back when I was a kid thats the first thing we did to a car was put a tach on it.My Impala SS had one from the factory in the dash.Thats how I figured how fast it would go,rpms,tire size,and rear end ratio.It might not run exactly that speed,but it would be close and might even be faster than the calculations because everybody reads a gauge different.Plus the tach could be low a little,or high.Anyway,I know you are right,they are not going to "get it"even if you prove it to them. Its pretty cheesy for a guy to say a car wont run that fast because of aerodynamics,and you proved it could with mathematics,because if its turning that many RPMs,its going that fast.You might fly in a lighter car,but when I was a kid we jacked up the back of the car and I know that helped hold the back end down.My Chevelle with air shocks in the back,I jacked it up to where L60s wouldnt rub and you felt like you were sliding out of the seat.Aerodynamics is just another tool of running fast.You want more air to go over the top of the car,so raising the back would lower the front,and get more air on top of the car.The angle would increase the pressure on the back tires.You can still get airborne though.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
