Hyper Ground setup`
I am starting a new thread regarding the extra daisy chained grounding setup for our cars. It was brought to our attention by Bubba966 and I thought I'd give it a shot on my 540i.
I used the scrap 8 gauge wire I have laying around and started to install it. I initially thought the valve cover bolt/nut should be enough to do but I was wrong. The nut itself is not conductive to electricity and was proven with my multimeter. In fact, there is not many places where we can get to actual grounding easily on the 540i.
I ended up just grounding from the last coil pack bolt on driver side to the power steering nut. Outstanding contact there. There is two grounding points on the driver fender as you can see all those brown wires. I didn't hook it up there because of my short scrap wire.
Some thing I noticed upon starting up. First of all, it starts up quicker... almost instantaneous... it takes a couple of seconds to start my car from cold.
As the engine warms up, it got smoother and smoother. Our V8 are notorious for those rocking due to the cams that are on our car... but boy... it really knocked it down alot. The revving is quick response... before it seems like there is a lag.
In any case, I need everyone to collaborate on this simple project. Where is easy grounding points on our V8? The coil packs thing does affect the way our cover sits... right now it is propped open a bit by the 8 gauge wire.
From the info Bubba966 showed...

There has to be 5 or 6 points of grounding... so let's try to get it right for our car. I am also doing three subthreads for Inline 6 M50 and M20/30 and the V8...

The V8 Ground project... This thread for the V8 owners...
The valve cover is definitely not a grounding point... it is a very poor contact due to gasket and the non-conducting nuts they used. The studs however are good grounds.
Right now I am using the last coil pack nut as grounding point.

The M50 Group... I think these group have just as hard as the V8 to ground the engine.

The M20/M30 Group... I think you guys got the easiest grounding project. However, I think it is important that you also include your coil pack as a grounding point... so don't forget about this part.

Seen this awhile back, think it might help for a clean install:

Maybe talk them into doing a group buy

1 Directly from the Battery to the "Distributor" (Might be a bit tricky for the battery under the back seat)
I would assume the critical components:
Engine Block
Transmission
Alternator
Intake Manifold/Throttle Body
Ignition Coil
Another Engine Ground or something else

oh jesus. it has infected you too? what's next, rotary exhaust tips to improve throttle response?
They don't do anything unless your factory grounds are worn/corroded/defective, in which case simply correcting or reinforcing the engine to chassis ground would do the same thing.
