computer fan turbo?

[lunarhighway]

i was thinking about useing a computer fan as some sort of cheap small electric turbo.

while i was looking for information i found this reader response on autospeed.com

"Airflow Fan

I stumbled across your article on the Turbo Zet and, while your power draw claim is accurate, it doesn't make electric supercharging completely unpractical. Your conclusion is that it would take over a thousand amps to power a 'real' supercharger electrically. However, a high-powered 12V computer ball-bearing cooling fan will run 131.5 cfm while drawing only .66 amps - only 7.92W in total. At that rate, you could run several computer fans in parallel and not even impact the alternator. These fans are designed for continuous use, as PCs usually stay switched on for years straight. Your thoughts?

Computer fans are designed to run in a virtually 'free-air' environment - in other words, they operate with barely any airflow restriction on their inlet and outlet sides.

The output air volume of a computer fan - or any electric fan with such a small current draw for that matter - falls off dramatically when it's being 'loaded' due to a flow restriction.

this would sugest it's not possible, but than i was thinking, what would happen if a few small fans where set up inline with eachother?

wouldn't this produce a multi stage effect where each successive fan would both help accelerate the air and deliver it to the next fan? this might not increase their total air-ouput, but it might distribute the load over several fans makeing it possible for these little fans to get the job done


i might get my hand one some used fans for free so that's why i'd be interested in useing them as an economy boost... i'm not looking for a real turbo conversion though
