Popular Mechanics did a scientific test on these things and a few others, every one of them failed miserably (average loss was 25 hp)

vortexing might be beneficial, but I seriously doubt they would create any sort of usable difference. For one, depending on where it's placed, it could have a huge effect (right after the air filter) or very little effect (right after the 90 deg. elbow) IF DESIGNED CORRECTLY. however, there's some things to consider:
-swirling air inside the tube does not necessarily mean swirling air into the intake/piston. Careful tuning of the part would have to be done to ensure that the swirlin created high-pressure, non-turbulent air into the intake tract past the valve.
-Such highly- tuned parts would only be beneficial for a certain Reynolds Number (engineering speak for flow velocity, density, and viscosity settings.)
-If not operating optimally, it would introduce extra turbulence and pull energy out of the air (you want energy in the air for combustion.)
-possibly screw with MAF/other engine management flow meters.
Besides, do you really expect $1.25 worth of galvanized tin to actually help?sigpic89 M3Comment

please state your credentials and your ability to speak on this product with any knowledge at all. do you have one?? . i have this on my car and ive noticed a considerable improvement in mpg and butt dyno.
in case you didnt know, and its obvious you dont, its "the vortex" that creates more power and MPG, not to mention smiles per gallon
My credentials? 30+ years on dynos and flowbenches, national championships in SCCA and IMSA, races won in SCCA, IMSA, Grand AM, IKF Karting, WERA, AFM, and ARRA motorcycle racing, vintage car racing, successful runs in AMA and International motorcycle twins racing. From 1969 to present. My aero work on bodies first won in 1971. My mechanical and fab work in 1969. I have used flowbenches and dynos extensively since 1975. I OWN and use both. I also use outside ones.
I'm obviously not as smart as you, but I'd suggest you go: 1) use a flow bench for a few months at least 2) use a real ENGINE dyno 3) run some pro races 4) ask the top 10 at any big race if they use fan style vortex generation in an inlet tract. I'll guarantee you they don't. If the tract is well sized, putting shit in it hurts.
The DRAG, PARASITIC drag created by those blades is quite significant. Fuck the vortex, you are in the middle of a tract. The fuel is not atomized at that point, either, and your precious vortex is gone in the chamber, where it does matter.
A near identical part called a swarup was made in the 70's and tested by several motorcycle magazines, it always lost power.
Those of us who use flow benches professionally have stuck a lot of things in inlet tracts over the years, we have at least a vague idea what happens. At the airspeeds and densities involved in an automotive inlet, these parts are a joke. No, they are a DRAG.Last edited by mdok; 10-01-2008, 11:04 AM.Comment

Wouldn't the "vortex" be completely disrupted by the throttle plate?The Keystone Killers

If Billy Mays says it works, you know I'm buying...
The logic is along the same lines as "I saw it in a movie, it must be true!"
The Vortex is a joke...thats why you can buy it at the "As Seen on TV" Store...sigpic

Now send him a Pringles can of poop to voice your dissatisfaction of his superior knowledge.
This forum needs a sarcasm smiley bad, it would have saved the poor guy from typing all that stuff out.
