Ah, the old 12V bilge fan strikes again. It'll be great when one of those cheap aluminum fins breaks off and jams the throttle plate wide open.
Actually there's a screen to prevent that from happening according to the faq. The faq also states a 7% gain in peak hp. It doesn't even have to provide any boost to achieve this, it only has to increase the engine's efficiency to nearly 100% by improving airflow at WOT...

Can't work. I thought you were being ironic, but if you actually believe this, I have a bridge to sell you.
The wires on that fan can't pull more than maybe 10 amps, and there's no way that little DC motor can move anywhere near the air a 2.8 would need at WOT. The fan itself will be a restriction to airflow. There is no way a spinning fan in a tube can produce boost. It will reach a maximum airflow and then it will just stop moving air because physics. Now, with a more powerful fan - maybe a leafblower - you could possibly overcome the pumping losses on a small displacement engine and gain a couple of HP from not having to physically suck the air in. Maybe. You still won't produce boost. Put your hand over the output on that little fan and the airflow will stall. It's not a compressor.
There are real, working electric superchargers, but their amp draw is ridiculous and they can only run in short bursts from a separate electrical system. This thing is Total BS. Even their claim that it doesn't use any power is BS. Any draw on the alternator will make it harder to turn, thus robbing power from the engine.

But in reading the faq, it says everything you are saying. It only turns on at WOT for expected short bursts. Comes with a 50amp fuse. It's not an 'always on' SC. From reading about it, I just expect it to compensate for poor intake design...again increasing the engine's efficiency to closer to 100% but not exceeding it. If it adds 10hp, it's more cost effective than a lot of mods...
I find it difficult to believe that people still fall for this nonsense. Then again, the producers of these useless devices prey on a sufficient number of folks with no grasp of basic science and physics to apparently make it worth resurrecting these scams from time to time.
Just add one of the "copper coil fuel ionizers" along with this fan and you too can miraculously gain 15 HP *and* 8-10 MPG...Order NOW. Supplies are limited!

Good marketing. Utter bovine defecation. 50 amps would incinerate those wires and there's no way on earth that an axial fan can move enough air to overcome the static air pressure already in the intake tract. Your engine simply CANNOT take in any more air unless it's compressed. There is nowhere to put it. Take a coffee can and attach this fan to the top of it, seal the joint and turn it on. No matter how fast it runs, or how many CFM it can move unrestricted, if there's nowhere for the air to go, the fan will just sit there chopping at the air already in the can. It will not compensate for a poor intake design, it will make it worse. But, go ahead and dyno the thing. It's been going around since 2006 at least.
IN THEORY this could work. Just like communism. At its basest form, it doesn't matter HOW the air is pumped. IF you were able to get a powerful enough electric motor, and IF you were able to provide it adequate electrical power, you could produce as much boost as you want. In fact, it could potentially eliminate ALL the negatives of current turbo or super charger systems. No lag, no drag on the engine, much simpler/cheaper installation, and very precise control of boost curves.
HOWEVER
The current reality is that existing technology will not support it, particularly in power delivery. Motors designed for RC aircraft applications are getting close both in terms of RPM and peak power, but they take a LOT of power to run. We're talking 44+ volts and multiple AH worth of power to run. This would put a huge load on a car's electrical system if you were to try to come up with some sort of transformer/capacitor arrangement. Now you're looking at an independent power delivery system (batteries) which add a lot of bulk and weight very quickly.

Your problem with a working electric turbo/super charger is the battery. Until "they" solve the problems of capacity, size/weight, and output this idea will never be truly possible. The paradox is that once the battery problem IS cracked, the question will then become why would you bother powering the car with an internal combustion engine when you can run it off of that new battery?
A turbocharger uses about 40+ hp to push one atmosphere of air pressure (14.7psi boost). Even just aiming for 3 psi boost would require a massive motor.
I enjoy comedy so I watched the vid. At about 7:15, you can hear the test dummies complain that the dyno was broken. THERE'S the problem! Had the dyno been working, it would have clearly shown that the electric supercharger added a massive amount of horsepower.

Again, no different than the E3 BS claims of more power.
And fierosound and Thunderstruck GT win the award for not watching the whole video... LOL
Try again, starting at 13:30...
These guys were obviously poking fun at the people who believe the claims, not trying to scam anyone.

The irony of people on this forum complaining about extraneous nonsense in a video on YouTube is just a bit… je ne sais quoi.
Though if it was some redneck doing the same thing with a Geo Metro, they probably would have watched the whole video. Oz accents and foreign cars is a bit too much to take in perhaps.

You can suck it Dobey...
Although, I haven't been active on here in close to 3 years because of the the issues you are most likely alluding to...
Edit: And that was a Geo Metro...

In theory this could work, but the extra belt driven alternator you would need to support it is going to make you wonder why you didn't just go with a real belt driven supercharger.

To make claims that this little fan could give an 80 horsepower boost is false and misleading advertising. This is a scam for the purpose of theft. It is stealing from the gullible and is wrong. These guys need to remember "what goes around comes around". Here is one that might produce some boost as it draws 124 amps.

You guys are blowing this out of proportion. It doesn't have to make boost to make power. Most intakes aren't ideal, and it's why N/A engines are generally only 80% efficient. If they become 85% efficient with a little extra push of air, then you'll see the 7% gain that the FAQ actually claims.
For instance, in the Mythbusters video, the car actually gained 10+% more power because the car ran so poorly and you saw the a/f ratio go from 9.x:1 to almost 11:1 ... Again, I don't look at the advertising claims. If a 2.8 can gain 10 rwhp from this, then for $175, it's the cheapest 10hp you'll ever buy.

Depends on your definition of efficiency. If you mean the energy content of the fuel that ends up as forward motion of the car then you are talking about less than 40%. I doubt this bilge pump can even break even and instead acts as a restriction in the air inlet.
The AUDI uses two exhaust-gas powered traditional turbos, one small and one large. The 48 volt electric supercharger takes about a quarter of second to activate and quickly spins the small turbo to its effective 70,000 rpm level. The intervention of the electric supercharger lasts for 2 to 3 seconds. It's job is just to reduce exhaust driven turbo lag.
The Porsche is a similar 48 volt system with an "always-on" system. No other details are given. But this ain't no 12 volt bilge fan.
