"Electrocharger"?

Interesting concept.

How that concept is executed is another thing.

The supplemental power must be negligible since the toothed belt isn't going to deliver any useful torque without quickly wearing out. Also the gear ratio is not conducive to any torque increase (large gear on the electrocharger is driving the smaller engine crank pulley?). If this is going to work at all (with little wear on the belt), it would be at higher engine and vehicle speeds.

ELECTROCHARGER is the most significant advancement in automotive performance in the past 100 years

Sorry, when I see that kind of hyperbole, I stop reading....

Colin,
Gee, I was going to use that line on my next product. Now I have to think of something original. :-)

Sorry Sherwood. I have an MBA in marketing, and even I think that wording shrieks "BS!"

:D
