Default Ducted fan electric supercharger brushless motor?

I understand that the cheap electric supercharger units on ebay don't work. I am assuming they use cheap standard inefficient brush motors. What if someone built one using a high quality R/C brushless motor?? Here are fan units and motors. Parts will be pricey....

Scroll to the bottom to see the largest fan unit.

These are the recomended motors to use with the above fan unit.

Someone try it and tell us if it works!!

well they look like nothing more than model airplane motors . . . not designed for car use or anything of the sort.

the basic principle is the same as a super charger, but realize that supercharger kits are expensive for a reason . . . R&D

You must first understand why the electric "superchargers" on ebay don't work.

A. They are not powerful enough
2. They are not able to draw enough power from the electrical system to effect performance because they are inefficient.

These brushless motors are much more effiecient then standard brushed motors. Brushless motors are the motors they use in electric cars (real electric cars, not toy cars). The entire principle behind FI is efficiency. If it takes more power to spin a turbine then the amount of power the spinning turbine creates by compressing the air, then of course the device is pointless, be it a belt driven supercharger or exhaust turbine.

If somebody did the R&D on brushless motors and ducted fans they could in theory work just as well as any of the conventional methods of FI available today.

That is why I put this post up.

Take a look at these, they also produce brushless motors for industrial and military aplications.

Perhaps bolt one of these to a supercharger unit. With the lower current draw, it could be ran all the time...

I've already spent too much on my car...that is why I am trying to dupe someone else to spend the money to try out my brainchild.
