Hello,
This is Geoff Knight, the designer and builder of my patented electric supercharger. I have seen several questions and comments on your forum and would like to address those. Also, this IS for real. Turbo Mag and Sport Compact are both doing multiple page articles on this awesome invention as they already know it to be real. It will completely revolutionize the industry as I am the only person to have ever developed this concept.
1--Why so expensive?
My cost on the first ten units--not the hours or patents, etc--only the cost of the parts was $2200 per supercharger. CNC cut gears, adapters, aluminum 6016 T6, etc are extremely expensive. I have since gone to 100 units per run dropping the cost by 35% and allowing me to wholesale to the public for $1995 (Shops also pay $1995) When I get to 300+ per run the cost will drop by another $15-20% and I may actually make some $$$ off of these.
2--how does it compare to a turbo?
On a stock engine which is limited to 6-7 psi the ESC will make 10-15% more power. A turbo does NOT make free hp like some may think. It takes backpressure to make boost, and street cars make double the pressure in the exhaust manifold compared to the intake manifold. The exhaust temps are also much higher.
3--how does it compare to a belt driven SC?
A crank driven blower takes more parasitic power as rpm goes up, and a typical SC running 7 psi takes 25hp @ 6000 rpm. My ESC will make 20-25% more power than a belt driven SC.
4--looks like an Eaton and starter motors.
That is what it all starts as, but the Eaton is fully race ported (VERY IMPORTANT)and powder coated and the three 4 hp motors are rewound to 6 hp (18hp total) on the basic model and 8hp (24hp total) on the race version. Basic model uses four lighweight 15lb racing batteries, and the race version uses six.
5-- why cant it be run continuous? This unit draws 1200 amps. The average alternator is 85 amps. You can almost make 1 psi from 85 amps--not 20 psi. Just like your starter, the unit draws current from batteries when needed, and a high-output alternator could recharge it in a few minutes. Electrical power is about 80% efficient during transfer, so an extra 40 amps from your alternator would require 36 minutes of charging to fully charge the batteries. That also assumes you are using 15-30 amps on your accessories--lights, wipers AC, stereo, etc all take a LOT of the alternators current. At night on a hot & rainy evening the 85 amp alternator may be all used up and the ESC batteries would NEVER charge. A 250 amp alternator assumes 200 available charging amps after accessories.
