http://www.fast-technology.com has a air filter with a a turbine fan inside that spins 30,000 rpm's. I'm sceptical about these kind-of things,but it looks like it will work(and its dyno proven) I'm more than likely going to buy one because i need a new air filter any way.
but since the fan will probly run off the battery will the hp increase even out since its draining from the battery?
or does it look practical?Should i go for it?
