Here's the deal man, the reason everyone is laughing is because this idea has already been capitalized on, search "electric super charger" on Ebay. And it is a SHITTY idea, those fans don't push NEARLY enough CFM to make any power. It's bullshit.

Sorry to ruin the fun everyone.

Ps. The rock thing was because it's so amazing that you've never heard of these thing, ESPECIALLY being a car person.
