Slingshot pass
OK, here's where things are wrong. By the way, I'm an MSc Aerodynamics student.


 * "This is an area where there is absolutely no air resistance at all" - Air resistance, commonly referred to as drag, applies to a body moving through a fluid, not the fluid itself. To say there would be "absolutely no air resistance at all" is also wrong. Pressure drag would be reduced, not eliminated, but skin friction would still be there.


 * When you say the air is "moving around", just refer to it as being turbulent.


 * "This creates almost like a vacume." - No. There are still air molecles everywhere so it is not anything like a vacuum. However the pressure in the wake region is reduced meaning the drag component caused by the pressure gradient across the car is reduced.


 * "This is when the hot and disrupted air (caused by the air being forced upward by the cars wings to achieve downforce) comes back down and is moving around violently." - Wrong. The turbulent air is caused by the tip vortices from the rear wing and the separated turbulent boundary layer.


 * "This is possible as his car is not experiencing air resistance" - Wrong. Air resistance is always being experienced. It is reduced, not eliminated.


 * "Due to the fact that you are moving with less engine power, you can brake fractionally later." - I don't see how this follows. You're still decelerating from the same speed to the same corner entry speed so the brakes are doing the same work.


 * "A motor racing cars aerodynamics is not designed for such manouvers" - Also not correct. Whilst primarily they are designed for running in the freestream, F1 teams do wind tunnel tests to reduce the negative effect of running in another car's wake.


 * "it will immediately slow the car down as the aerodynamics start working." - The car is always generating aerodynamic forces. They don't ever turn off.


 * "the aerodynamics come to full effect." - This makes no sense at all. What is full effect?


 * "A sudden increase of oversteer will effect the car which could, but rarely, lead to the driver colliding with the car in front leading to an accident." - You're assuming the car is generating a lot of downforce to begin with. If the car has no aerodynamic devices per se then the only effect will be that drag is suddenly increased.

One other thing - it's a very technical article yet you have cited no sources at all. You need to cite sources otherwise it is termed original research, which is not allowed. Readro 12:31, 1 August 2007 (UTC)
