have you guys heard of this thing??

 

Yes.

And most likely no.

And next time search.

 

hahaa even if this did work, look at both pictures and count the fins in each. thats a top quality machined product right thier.

plus look in the first pic, the seam isnt even welded.

good people have such good scams to get rich.


nonetheless if anything this is an air restriction, and you will get worse gas mileage.

 

It's funny how everyone assumes these things don't work. Have you ever used one? Also check the feedback on that auction. There are several people that have bought this and they aren't complaining about it not working.

 

negative.

 

Airing up your tires will probably get you more gas savings than this thing will.

 

in my machine class we did a test on a 4 cyl v6 and v8, none of which benifited at all.. filled all cars up, drove on interstate till half tank w/ out the "toy" then did the same w/ "toy" installed and saw no gain, only a 4% loss at the most. stay away from scams buddy.

 

Popular Mechanics did a test of a buncha these gadgets recently and did a full write-up on them, including the vortex spinner thing. What a freakin joke. Think of it this way, if it was just that easy, to add a spinner thing, at least one production car out there would have it They don't because it is cheap and stupid. A scam. a piece of sheet metal with fins will not help atomization of anything. Ugh I can't believe we're actually seeing this thread.

 

holy sh*t. This guy makes a ton of money. He's not selling a votex thing. he's selling a how to get rich scheme.

 

I could make one of those with a beer can.

 

alright man, throw one in your intake and test it for us. actully, just hit a beer can with a lawn mower, then put THAT in your intake tube, its the same thing.

its and EASY 50hp.

 

my brother-in-law went to UTI in Charlotte for Nascar mechanics. He said they did a before and after dyno with one of these installed on a motor. I dont specifically remember what amount of horsepoer or TQ he said they lost, but it was substantial.

 

Right from popular mechanics... Mike Allen, September 2005 Issue
"VORTEX GENERATORS
These devices, which are usually installed on the upstream side of the mass airflow (MAF) sensor, use stationary vanes or, on some devices, spinning blades to make the inlet air between the air cleaner and intake manifold whirl around in a mini-tornado. This vortex supposedly mixes fuel more thoroughly with air, which means the fuel will, theoretically, burn more completely in the combustion chamber. Trouble is, there's a lot of intake tract downstream from these devices designed to maximize a smooth airflow. Turbulence, coupled with the restricted airflow caused by the device, can only reduce the amount of air sucked into the manifold. Less air means less power.

Again, we tested two devices. The TornadoFuelSaver is a nicely made stainless steel contraption, available in an assortment of sizes to fit most vehicles. We installed it on our truck's intake tract immediately upstream of the MAF sensor. We purchased the second device, the Intake Twister, on eBay. It was crudely handmade from sheet-aluminum flashing and pop rivets. It looked like something we could make in about 10 minutes from an old soda can. The staff at UTI was reluctant to install it: The bent sheetmetal vanes looked as if they might break off and be digested by the engine. The device is one-size-fits-all, and is simply bent into a curl to insert it into the intake duct.

THE DYNO SAYS: Both devices reduced peak horsepower by more than 10 percent. The Intake Twister increased fuel consumption by about 20 percent; the TornadoFuelSaver provided no significant change."

 

IMO I think the technology may still work, just not in the fashion to which it's presented. Putting these devises in the intake before the TB butterfly's would appear to break up any vortex these things may create. I always wondered how some small ones would work in the actual intake runners after the TB. The vortex wouldn't be affected and you may get an increase with better velocity and fuel atomization. I may experiment with the spiralmax inserts.

 

Those devices only help non tuned intake runnered vehicles, and have no place in modern cars except to make the people that sell them money. Most of those type devices actually lower HP and availble torque.

They do not make more power, because they do not change the emissions in the car. You can't make more power without raising or lowering emissions.

Thread closed.

Use some common sense.
