Actually....

This electric blower... well...

Try this, a turbo vane, spins at about 60k rpm(more on some), with an extreme pitch, which is why they dont make boost until the the velocity and pressure build in the exhuast...
My thought, HUGE electirc motor, with a METAL compressor fan.....

My thought, POS, waste of money

On most alterntor systems, it is not myth that they reduce power, as most now a one-wire, and draw directly from the battery, thus causeing more power to charge the battery.

NOW, why do race cars still use alternators right?

Well, some dont...BUT, they are running HUGE deep cycle bats..or they are running totally nehcanicla iginition (magneto) and the electronis themselves dont draw enough power to affect anything.., but these are alcky and nitro motors..

regular bracket racers use alts, because, the ignition and other components, draw power, and as the power increases, it drops the voltage, and iginiton etc start to lose power..

So... yes, more power draw(electrically), more load on the engine/alt..othewise, like was stated, perpetul power...

I say go with a small homebuilt turbo set-up...or a centrifigal charger(non roots or screw)..thise are THE most efficient power adders..(except nitrous, adn no one wants to touch that one), the turbo being the most efficient...

Again, improve the exhaust, adn the airflow in...larger tubing, less bends less restrictions...

More exhaust out, the more you can get in, and if you improve the intake...

From there, you are getting into mechanical, or computer mods...

Anyway...
