There's not. Your engine needs the MAFS to know how much fuel to put into the engine.

And please, for the love of God, get rid of the electric superchrger. They don't flow enough CFM and are actually a restriction to your intake system at higher RPM.

Simply put, fans cannot compress air to the pressures necessary for generating large amounts of horsepower, the reason why superchargers and turbochargers are robustly built. A rough calculation has fans able to output less than 0.5 psi while the real stuff can boost pressures over 30 psi and more. Another way to look at this is that a fan is designed to move a volume of air without any appreciable amount of pressure behind it while the turbos and superchargers do both. Lastly no one has seriously done the R & D to develop an electric supercharger as this will be just as expensive as the others.From http://www.saturnfans.com/forums/archive/index.php/t-89320.html
There are many reasons why these things don't work. I'll try to give a few.

1) Those cheap blower motors are not designed to pressurize air and do a very poor job of it. These type of blowers were designed simply to move air, not create areas of higher pressure. These types of blowers are only capable of creating a very slight pressure increase if any in the cars intake.

2) Since they use electrical power they put a large draw on the battery and alternator which makes then usable for only short periods. In order to run it continuously you would likely need a larger alternator which would suck more power from the engine than what you would be gaining from running the blower.

3) Many of these cheap fans can actually reduce power at higher rpms because they can not flow enough air into the engine. At high revs the engine may flow more CFM than the cheap blower can provide.

4) These fans are typically made of cheap plastic and can break apart, sending pieces of the fan through the engine.

If you need more info just google "why electric superchargers don't work".
