LMAO, it goes on...I asked the BMW teacher at my school about that system, just out of curiosity...and he said that it would'nt improve MPG significantly to raise average MPG, vs. a car that
is equipped with it.
"it was an idea designed to save the robbing of power during performance driving, so that people don't risk the bright idea, of underdriving the alternator with pulley kits"
"many E46 M3's came back withproblems that came of a result of aftermarket pulley's, that underdrive the cars charging system. Not always the brightest idea on a car, with more electronics than their home"
I am assuming that these people changed the pulley's back out and took the car back to the dealer and got work done under warrant. (Bastards)
Bottomline here is that it won't improve MPG (eg; 24mpg average vs 25mpg average) And thats all I stated.
