I am curious if anyone here is familiar with the Formula 1 cars that were banned for being too quick?

Why not use this similar principle to improve rear aero on your car but have a tube coming out of the center of the back of your car pushing air out. Has anyone tried to model this or tried it? Would something like this help to smooth out the aero on the back of the car?

I think it was Ski-doo or Bombardier snowmobile engines which were used to vacuum the cars onto the track.I had Paul von Valkenburg's (SP?) Race Car Design book but it was loaned and never returned (drat!) I believe,at the end of his book,he showed a Corvette with rear suction,and it did reduce the wake and drag,however,as BicycleBob has already mentioned,absorbed more energy than it saved,for a net loss in efficiency.People all over the place are still working to make this work,but the jury is still out on this one.
