all it does is put the air in your intake into a vortec which will send the air into the engine faster...so i say it would work but you prob wouldn't notice much, if anything at all imo

Add Up To 10 Additional Horsepower

At least they made it somewhat believable. Most of the time they claim +25hp.

Waste. Of. Money.

It does nothing but put the incoming air into a completely useless turbulent vortex in front of the throttle plate. If it was placed behind the throttle plate I could see it maybe causing a useful vortex. But where it is placed before the throttle plate it's useless. They don't do anything but make your intake whistle.

i would love to see one of those dyno'd to see if it has any affect

It's like taking one of those pinwheel things you see people have in their front yard, and putting it into your intake.

Silly silly, lol.

X2 its a bad location....
Throttle body spacers from most companies produce a vortex located behind the plate... that's a better bet for actual gains

Even that wouldn't have much use, since the air would just become a turbulent mess as soon as it hit the plenum anyway.


Just a restriction. It looks believable, though... which is why people fall for it. Especially these days, when money is tight, and people want to save on gas!

I've seen these tested before, they do not work!

Could you post the test results so everyone else can see.

Had it long time ago when I was a great ricer..
Not worth it to me..

[bcjammerx]

even behind the throttle plate I don't see a benefit...you've still got the runners to take into consideration.

there have been several magazines that have tested it and found a decrease in both performance and mpg's. One being consumer reports...not digest...reports. Very reputable/reliable/scientific group of folks.

it's what we call...snake oil there are many others.

here's is a link to another reputable mag...

Once the air hits the back of the valve its just going to become turbulent again if the tornado was after the throttle plate.

I'm going to start selling these for use in exhausts!

Yeah but what if you were to put a CCW rotation on the air? In theory that would force the air down into the left to right curved runners faster, would it not?

Can you show us just how turbulent the air becomes after hitting the back of a valve? wait a minute. If the spiral of air can get the air to the back of the valve faster than the sock TB & runner can it's already done it's job. Who cares about after that valve? This topic has nothing to do with air passing the valve seat, that's comes down to what type of valve job you have.
