What is the strongest 3" 12V ducted fan combo?


Just looking for a basic idea here.
Don't have a jet in mind yet.
Just want the ducted fan/motor combo that moves the most air.
Weight is not an issue. I'm thinking a 24000 RPM motor? Is there faster in this size? I guess even a four inch one would work too. Thanks for any recommendations.

Also, is there any way to convert Newtons to CFM (cubic feet/min of air?)

Thanks,
-Chris

Man, is this thread old...

Electric superchargers DO NOT WORK. Don't waste your time with them. Dusted fans generate flow, NOT pressure.

READ ME

An excerpt from the above post:
Short and sweet why electric superchargers aren't practicle:
Figure a smallish blower(like mine) takes 30 HP to spin fast enough to generate 15 psi of boost. 30 HP is 22,371 watts, at 13.5V(nominal automotive system) thats 1,600 amps.

Well, if you point it down you won't have a VTOL but it might reduce the weight a enough that the Prius will go faster.
