Umm, what??

I don't know anything about anything, but that does not look right.

Its not a true supercharger. It is an "electric supercharger". Which means its running off of the battery. 1 it shortens your battery life. 2 it comes no where close to a real turbo or sc. 3. when its not being used its more of a restriction on your intake. I know your not buying it cuz you know it didnt sound right. Its along the same lines of the turbonator. Its cheaply made junk made just to make money not perform. For that much money you might as well buy a midget and have him blow into your intake =P

Electric superchargers can be done. However, they need some form of controller that watches the vehicle's RPMs as well as the airflow necessary to produce 2 psi. If you could control the speed of the electronic supercharger, it'd be actually useful.

AFAIK, most performance upgrades in the range of turbochargers and superchargers require upgrading the fuel and ignition systems. Even N20 kits run best as a wet shot, which I understand is fuel included with the kit. With older cars, that's not necessarily true. Carburators automatically add fuel in relation to airflow, but there's a market for the computer-ran MPFI or SEFI cars like ours...

Electronic superchargers have the potential to add the most horsepower a car can handle without overloading the fuel or ignition systems. 2psi would probably be the most a car could handle without the injectors locking up, and that's not including higher volumetric efficiencies. If marketed correctly, they could be a supplementary component to a car.

The problem with them, however, is the fact that you're directly converting electronic energy to mechanical energy.

In the most simplistic explanation, motors are used to produce energy. Automotive internal combustion engines do this by using hidden energy in fuel to produce pressure inside chambers to move components. In our piston motors, we require momentum to keep moving... not to mention overcoming inertia. This is why the car must idle at the speed it does; not doing this would put too much strain on the motor.

Turbochargers produce so much power, because it requires no extra electronic energy to produce power. Considering only 1/3 of the energy of fuel is used to move the motor, the other 2/3's of the energy is expelled... to turn the turbocharger. Some 210 kW in the form of heat energy is used in the highest performance applications of turbocharged Saturns, and it still takes about 100kw in common turbocharging applications.

Superchargers work, because they tap into the energy the motor is already using to make more power. It's still a lot of kW of mechanical energy to produce that said power. You can't make power without energy.

Nitrous simply uses potential energy to make horsepower. Most nitrous kits produce horsepower directly related to the shot size, as they simply and efficiently inject either nitrogen and oxygen, or the two of those with fuel at an optimum ratio to make horsepower. There's no need for an outside source for power. That's probably why it's so popular.

Electric superchargers fail to do what they say they do is due to the many factors that the companies fail to consider: the energy it takes to compress air, the strain on the battery or alternator, the required strength the electric motor needed, and the very science of forced induction.

If you could make an electric supercharger kit for 200~ and produce the boost you claim, you may have a market... but this one is very much fake
