Head grounding on the AAN

Draky · Post by **Draky** » Sat Jun 06, 2015 2:13 am

I have been doing some research on ways of making an engine more efficient and read how some people are grounding their heads to a ground point directly. The thought behind that is the spark plugs ground to the head, why not have an extra ground there for efficiency? Makes sense so I was wondering if it was even possible on the AAN using what's already there and/or if it was if anyone could point out a good way to do it?

If it's not feasible then is there another place on the AAN someone would recommend?

Thanks guys for the help

Run a strap off any bolt on the head, valve cover, intake mani.

Thanks for the help Scubagil, I was just curious if anyone had any advise that maybe they did... ran from this bolt here to ground to there. But that's cool, I'm thinking of running a ground from the valve cover (the ground where the 2.0T coils are grounded) and then maybe the other side of the engine as well just for overkill on the grounding. I figure you can't have too much grounding.

Its a good idea, I've heard the factory grounds are pretty minimal.

Had a thought, one ground from the valve cover where the coils are grounded to and the other from the alternator bracket.

I also was looking at the alternator today and saw the cable going to the battery was pretty thin. Would anyone recommend running a 0 gauge? I have about 50 feet right now and I'm thinking of running the 0 gauge from the alternator to the battery. I'm actually pretty surprised that the power cable is as thin as it is.

I had a no start caused by a bad engine block ground (the one near the starter) about a year ago. Since I'm lazy, I just grounded one of the studs for the heat shield above the exhaust mani to the strut brace. Fixed the no start. Then I had the car dyno tuned at EFIx.

I had the engine out a month ago and replaced the bad block ground and lost the extra ground. The car started, but I had an ignition break up at high rpm/boost. When I added the extra ground back the miss went away, no oth r changes.

This is more likely due to other failing grounds than a design flaw, but again I'm lazy and it worked.

The mule is revving to 8500 on stock grounds. Although sometimes the tach bounces around a little weird around 7500-8500.
