Better grounding?

Is there any good necessary reason to "shore up" your grounds? I have read some people have noticed improvements but I'm wondering if it's psychological.

 
There are published positive results from better grounding. Both on the web and magazines. Roughly 1-3hp dyno proven. Some people report no HP gain but do notice improved throttle response

 
I got a few powerful lessons in this, via welding, strange headgaskets, steel sleeved plug holes, no resistance in the copper wound insulated wires...

and the grotesque world we drive through caking via ionization to the suby aluminum boxer...

it is not even about horsepower.

just today, finally getting to the engine bay after the new headgasket, stuff from the disaster was still everywhere.. changed runtime right after cleaining engine.

hook up what they designed, and if it is still weird, get cleaning and flushing.. and if that don't work, try the steel sleeves, and step up ignition..

also paint in places, like the driveshaft is a huge move..or the tunnel.

I got a video of my sube getting hit by lightning off a metal street pole.. 2 months later the headgasket was fried.

looking back at advice in another forum... lightweight gasses inert was mentioned as a source... it was the truth. the headgasket had been seeping for more than a year.

amazing stuff, the electrical and a suby boxer. the self balance also has another precision we all have to work over eventually...and an awesome lesson to keep.

 
in a direct current system like a car the electrons flow through the ground, so making sure you have a sure ground will make everything run better.

I was just thinking of this, 3 degrees and snowing...

I found that on the old one (ea82) the driver side fires strong and content, and even handles what could be disasters.. passenger side can't.

deciphering I realized the alternator bracket, and distributor, and engine ground all bridge the head to peace, as well as 3 bearings on drivers cam casing, 2 on passenger making it even more weird....

I am goiung to fake a bracket, across the head to the block.. suby engines do next to nothing on the passenger side head, which is quite odd.. as linear to rotation favors driver side.. if to humor a gound, why not loop back to passenger to chassis?

is there a static bomb they know about, hence choosing the driver side for redundant ground?

anybody tried a cable from passenger head to chassis?

Grounding kit is what you're referring to. I have one on mine and it does seem to help a bit with low end torque/ throttle response. Just search Subaru grounding kit. I'm sure something will come up.

 
I had a ground mod kit on mine ever since owning the car, so it's hard to say if I noticed a difference or not. I guess the idea of it is that it will smooth out the power band. There is some good info on them over on NABISCO.

 
I did a custom grounding setup on my old car. It seemed to make a difference as far as cold weather starting, headlight brightness and radio performance. The most important upgrades in this area I would think would be connections between the battery to body and battery to engine block/head to ensure continuity of the entire electrical system. Stock connections can corrode over time, so this is especially important on older vehicles. Probably not a issue on your late model WRX though. Sorry if the article in the forementioned link says any of this, I didn't check.

 
In anyones opinion would just adding an extra wire from the battery + to the Alt + give me anything worth while?

 
FYI you can buy decent quality solid copper grounding kits on E-Bay for cheap. I bought one for my last car and threw out the funky attachment they had for the battery with all the bolts on it. I just ran every important wire to the battery connection and daisy chained the not so important ones.
