    Has any body tried the new Tornado? yah , it's a thing that is said to give you more power and gas mileage, by twirling the air around ? or is it just a gimmic?

    Vortex generators have been found to help some TBI systems, but will absolutely screw up a carbureted system. Some information on vortex generators can be found in David Vizard's book on carburetors and intake manifolds.

    It'd be a total waste of money on a carbureted system. If you have a Quadrajet, tests done by a LOT of different sources show that the best arrangement to have above the Q-jet is a stock factory air cleaner. Any other additions inside the air cleaner decrease the efficiency of a Quadrajet. It seems the engineers knew what they were doing. If you have a square-bore Holley, some slight performance gains can be realized by using a "stub stack."
