This is really common sense. If you think of what happens to the air as it is sucked through the tornado, you will understand it was a good theory, but cant work. First the air travels through the intake tubing past the tornado causing ONE mass of spining air. it the hits the throttle body and is split as it travels into the plenum or manifold. Think about this, it has not even reached the cylinder and it has been split in half straight down the center of the vortex. Now that it is in the manifold, it is being pulled every direction possile by all of the 8 cylinders.
No it does not work. I have heard of many people geting them, mostly truck owners and they have told me that they noticed no power increase and actually a slight increase in fuel consumption.
if they could actually make is spin in each cylinder, it would work. they only purpose of this is to hel better the atomization better. The better the fuel is disspersed"atomized" the more volitale it becomes and the more intense the explosion....therfore more power is created. As I said, good therory but it was a poor invention at best.
Any time somthing says its going to add hp and increase fuel milage, do some research and try to find out how and why it would do that and if it is possible.
Try this for a test, Why dose Nitous Oxide increase horsepower. If you said because it is extreamley flamable, your wrong.
Nitrous Oxide is not even flamable.......... It must be magic or it just must pissss the engine off and raise its adrenaline.
The simple facts are that if you are reading this post, you obviously have a computer and internet access. You can learn anything you want be doing some research on here and the best part is that it is free and you can determine what will work and what is a scam and what will add hp and what wont do anything other than empty your wallet.
Many parts you can get are only as good as the stickers they put in the box .The leaf blower is a better idea, at least it make sense
