let see. How should I put this.

The tornado works. It makes air "twisted". But in cars' applications, it DOES NOT.

Here's why:

1. It placed at the beginning of the intake system.
2. The Intake Pipe's diameter is small, 3" is the max you'll see.
3. From the tornado's place to the Intake manifld is NOT a straight line,and a LONG line.
4. The intake draws air in at high CFM (cubic feet per minutes).
5. Air does circulate as STATE by physics after pass through the tornado.
6. However due to high CFM, air current path will bounce off the insidewall (due to small radius) of the intake tube so hard and fast that it won't remain the cyclone shape anymore. Because just like every other form (gas, solid, liquid, etc), the angle of refraction of each path - in this case is the air path - will be different, and thus in massive amount of collision, it'll affect the flow.
7. Also, when entering the manifold, it must go to a bent area, which will so dramatically reduce the cylcone air that the tornado's create.
8. Therefore, it WON'T WORK.

Have you hever see that they place the tonado in a long- 3" -bent tube and see that air actually circulate @ the end of that tube. NO. Because in both REAL LIFE and PHYSIC's CALCULATION, it WILL NOT work.


The sample water test that they show on TV is more affective because water's is heavier, the suction amount is much much lessen, and also because of water's buoyancy that they tends to stick together and forms a larger body and thus won't collide with each other like air does for an intake system. Also, their tube is MUCH MUCH larger and they placed the tornado in the middle of the tube.

oh yea, and it works for you because you FEEL it's different.

gas milage can be affected by many ways: Tire's pressure, weight, how hard you drive & cornering, road condition, what type of gas, etc. that the tornado won't even come close.
