Anyone ever seen this in use?

[DR.Q]

I know someone that knows someone that has one and is pretty impressed with it. Although the 'private' feedback leaves one wondering a tad.

I think it was tested in one of the magazines along with the Tornado thing. Both are snake oil scams. They don't work. They said that the fan blows less air than what actually comes through the intake....so it's almost like getting one of those portable fans and putting it in a wind tunnel and saying "Hey, this portable fan is making a 20% difference in wind speed and volume"It's only $27 so I guess it's not a huge loss but why let this guy get rich by scamming people?

as a matter of fact, that device would LOWER your horsepower.

a VH45DE at 7000 rpm is pulling more air than that "compressor" can pump, creating a restriction, and lowering peak horsepower.

that compressor is rated at 350 CFM, meanwhile the VH is pulling close to 450 CFM at 7000 rpm.

Electric Superchargers have been proven to work. IIRC, most if them will create the equivolent of 1~2psi.

It depends on how you hook that thing up as to wheather or not it will create a restriction at redline. If you put it inline between the air box and the TB, it would probably create a restriction. Now, you could use the Electric Supercharger as an Add-on.

You would need to put a "Y' somewhere between the AirBox and the TB. This would allow the "supercharger" to add pressure down low (If it actually does anything), and not cause any restriction up high. It would probably compliment the vaccum that the engine makes at High RPMs.

Now, I doubt the the Motor actually delivers "350 CFM" like it is claimed to. And about the description saying, the faster you spin the motor/fan, the more pressure it creates. That is not really true. You will come to the point of diminishing returns. I would estimate the motor closer to 75~100 CFM.

If one has some engineering training, one can quickly run an energy balance and determin the mentioned electric 'super-charger, will, if it has 60% efficiency( pretty good and highly unlikely its that good), boost the 400 SCFM flow by about 1" of water. After allowing a minimum of 5" of water additional pressure drop for the inlet,exit, and directional changes, no realistic way it can ADD to WOT performance. It will probably give slightly better low speed throttle response feel though.
