i wouldn't buy this cuz i could prolly make one in my garage. has anyone ever used it? does it really add hp and mileage? just curious, if the gains are signifigant i will probably give it a shot but if not i wont bother. any input is appreciated

Most people here tend to dismiss devices like that as simple fraud/obstruction in the intake/etc. As such, I don't know if one has actually been tested.

If you've got the money & time, it would be wonderful to actually read a review of one, possibly with dyno numbers & fuel economy numbers.

From the auction: If you are dissatisfied, return it within 30 days from when you receive,*for a full refund of final bid price. If it doesn't do anything, you're out $10 - the price of shipping. I think it might be worth trying. If it does everything it claims, you'd save money in fuel fairly rapidly.

Waste of time and money. Don't bother. Thread over. :)

but has anyone used it and can say wether or not it makes any difference?

i doubt even a rotary is an exception to this fraud device...

Yup, Consumer Reports tried out all these vortex tornado things and it does nothing for fuel economy or power. Heck, $30 for a bent piece of stainless steel...

EDIT: If something this simple, cheap, and easy to make improved fuel economy and power so much, every car would come with one from the factory.

i believe someone in the past posted their results of a small hp loss on the dyno due to the intake restriction.

get two and double your hp!!! :)

Hell, send me the money and I'll blow enough sunshine up your ass you'll think you're the smartest, fastest driver on the road! :rlaugh:

Oh, and PT Barnum is waiting for you in the after life.

yep

Look at the throttle body. There's 3 separate chambers. Even if it did work the "swirling" effect would get fucked up there.

May improve fuel economy, due to the intake restriction it will be. Similar effect could be had by covering part of your air filter, or shoving a tennis ball under your gas pedal.

These are useless, though one of them had a proven HP gain one one of chevy's VORTEC trucks!

I have never seen it do anything but waste money and loose power on every single other application I have seen.

Sometimes they come loose and turn sideways, causing some interesting sounds and effects.

Dont waste your time and money even reading about it :p
