Re: Tornado Under the HooD!! blah blah
Waste of money! What you would want to do is straighten the airflow in this area to maximize flow through the venturi's, not swirl it around. Combustion chamber swirling is a function of head design and would in no way be enhanced by this product. Some turbulence in the intake runners can be good in low rpm torque engines as it can help keep the fuel suspended in the air, but too much leads to puddling and inconsistent fuel delivery. This product would not provide any help in the runners either, could actually hurt air/fuel flow. Just another in a looooong list of worthless gadgets marketed to the automotive world. I almost wish I had one to run some dyno tests on several engines/intake configurations and prove this thing is junk, but that would be too darn much work for nothing.
