Hello everyone.
I can now specifically report about the installation of a Stiffening cap and grounding in my E46.
Here is a list of what's installed:
a. 2x 4GA ground cables in the engine bay
b. 2x 4GA ground cables in boot for battery
c. 1x 1Farad capacitor across battery terminals
I can safely say that got not much diff in terms of performance but the car starts like it is on steroids... The starter just cranks like crazy and the engine kicks into life really fast.
So far i have measured the fuel consumption and there is no marked difference.
I have a feeling that for a new E46, the grounding does not give that much of a difference but for an older car perhaps there may be greater gains as the negative terminals may have some corrossion and such. When i measured the voltage drop across the chassis and battery terminal, the reading was <250mv when cranking before the cables. After cables, the losses dropped to <50mv so not really very exciting..... :|
So much so for now.....
