Tornado product
Has anyone installed the "Tornado" product on their truck? This is the product that creates a 'tornado' effect for the air intake? Apparently it saves gas, etc.
Im curious if anyone has installed this, or better yet, does anyone have it installed along with an air intake kit like k&N or volant?

I used one in my '01 GMC 3500 CC dually with the 8.1 gas motor. I kept good gas records and noticed a difference after a few tanks and a long trip. I went from 10.2 MPG to 11.3 mpg unloaded. Loaded down it didn't make a difference. You make your own opinion, other aftermarket companies(Airaid, motorvation) make their own version so I wouldn't think it was a total hoax. As for big gains I don't think I would buy one for my '04, but one mile to the gallon made a difference on my big block GMC.

Chances are very very small that the air would still "swirl" after going through the throttle plate and upper plenum of the intake manifold. If you've ever seen a cut away of an intake, you can see that a large amount of air enters the lower plenum. That is like a big vat for air, then the individual cylinder runners draw air from the lower plenum like straws. The air is drawn in by the cynlinder, not forced in by the intake. The air would not be "swirriling" by the time it hit the fuel injector.

I could see it helping a small amount with carbed air as it could help atomize the fuel, maybe. However you can buy intake gaskets with mesh installed that work better.

But the infomercial looked so good. What about when they put the "tornado" over the little cylander, and the little fan thing starts spinning real fast....then when he removes the "tornado" it slows down? Also they dyno'ed it and it added 20 HP.....and they had a guy there that was a highschool autoshop teacher and he said it worked.

Lets see, that piece of sheet metal can probably be bought for less than 2 bucks if you were buying 6-800,000 of them. If Ford or any other manuf could grab another 1mpg for 2 bucks per vehicle................dont you think they would??
I tend to believe the same thing about these high priced air filters and most of the other so called aftermarket improvements they sell. 5.4 at 300hp.. Add a dual catback exhaust = 10-15%, Chip = 10-15%, Airade induction =10%... If we figure 10% for each we're at 399hp....yeah right...
