Tornado....Does it work?

[bigred_stroker]

Everyone has heard of or read about the Tornado fuel saver product. My question is, on the 7.3L does it make a difference or not?

I tried one on my old truck('02 F-350, gasser) and when you started it up it would sputter and stall out. Talked to a tech and he said that they don't work w/ vehicles that have MAP sensors. But that's just my experience

ON A 7.3L IT WONT DO ANYTHING YOU HAVE A TURBO.

i had one in an old beater car when i bought it...i took it out and the car ran better and got better milage...but to answer your ? what it does is puts the air into a spinning pattern...once it hits your turbo that is destroyed anyway, its useless to you even more then any naturally asperated car

Yeah we had quite a conversation about this on here last year. The consensus is that if you have a turbo or otherwise forced induction this is useless. Also a good point is that this is made out of thin sheet metal w/ pop-rivets. Not good things to be going through your engine in case one of those rivets decides to work loose. Now I will concede that I DO have one in my wifes car and my Dad has one in his ranger 4-cyl. He claims it helped his a lot as he has to go up the same hill everyday to work and he says w/ this tornado he can pull it in 5th gear where before he had to downshift. I really did not see much difference in my wifes car to be honest. I'm gonna take it out and see if anything changes.

I think it'll only help significanly in carbed cars. Put one in my 99 4.6L expy and it did nothing at all. The 70-100 bucks is better spent on fuel if you ask me. Turboed it does nothing.

Throttle body spacers work on the same idea, tried that too in the 4.6 and it lost milage and a little less power too. Garbage.
