DIY: Grounding kit Install - Page 2

My wire manufacture says 100% Copper content! Oxygen Free Cable, the jacked is able to with stand the engine heat, as i have had no reported problems, with over 80 kits that i have sold. =) YS those are great grounding points.

can we use ordinary ground wires from sound systems like monster cables

nme3 · 06-30-2003

what kind of hp gains did you all notice, if any at all?

YS · 06-30-2003

that's what i ued .... Monster cable. I got a left over from installing my sound system. 4G and 8G cable

happies713 · 06-30-2003

I could use monster cable but, i that would make the cost, higher, than i would like it to be.
I want the kit to cost as much as a DIY kit, but good quality. Im trying to save you some time, by not having to source the items and crimp the connections and cut the wire. =) Install is about 45 min.

ys the ground in the valve cover? do we need to scrape the paint of the bolt? so we can get a good ground , coz the direct coil cover is made of plastic right? so the contact is just the bolt holding the coil system?

i did

happies713 · 07-01-2003

i havent dynoed a civic, but on a toyota matrix, it did show a gain, not sure how much.

i have recieved numerous comments on how the shift from 2-3 feels stronger, in many celicas, and toyota matrix.

Hey -

You have to be careful what is grounded. Honda grounded certain parts / locations for a reason. If you just start running ground wires everywhere you're going to have eddy currents and you might just f#ck something up. Technically if you re-run the factory ground wires you should be fine - but I really wouldn't mess with it beyond that! Take it from an electrical engineer.....

YS · 07-02-2003

so which part can we grounded????

opto_isolator · 07-02-2003

Well, I personally wouldn't touch anything, since I really don't see how this could give you any gains. If the factory grounds are corroded or loose, that's a different story. However it rarely happens that they become loose, possibly corroded.

So if you do change things - just replace the factory ground wire from the battery, plus the one on the transmission and engine block. This may help with current flow to and from the battery, but there is also a ground wire on the alternator as well if I'm not mistaken - this would also have to be changed if you are going to start playing around with the other wires.

Other than that - I wouldn't mess with anything else. Not to rag on the guy who did any of this, but I really doubt that you saw any "real" gains from this - possibly noise in the radio was gone, but better shifting? More power? Highly unlikely.

Please dont Knock Grounding until you have tried it. For a fact i stated that does work, if my grounding kit did not "gain much" or improve much anything, i would not have sold 80+ kits.
Look at 350z owners, they are equipped with grounding kits all the time. www.my350z.com
check out matrixowners.com, or newcelica.net every single car that has the kit has reported a small gain if none, better throttle response and increased MPG, brighter head lights.

Why does NISMO offer a grounding kit to 350z owners? Why does Mitsubishi offer a grounding kit as an option on their Lancer Evolution? Why did Import tuner test a Suzuki aero with a gain of 3-4 hp on the dyno? Because they work. =) its simple easy and effective.

More power = very doubtful unless there is alot of resistance within the old wires.

What size wires are they?
Do you have a wire that goes from the Batter to the alternator?

opto_isolator as for running more ground wires. you should know this if your an electrical engineer. electricty takes the path with the least resistance. more possible ground points the better. (granted too many it just starts to get rediculous.)

profurious · 07-02-2003

this grounding stuff is for real, no doubt you will gain some good performance #'s from it.

Yes - but there is more to it than that! Eddy currents (ie circulating currents) are caused by voltage differentials. You have the possibility of creating voltage differentials when you have ground loops. Ground loops are more common (and notorious) in home audio equipment, as the humming you hear coming from the speakers. They can and will damage equipment if not dealt with properly. When you start running ground wires all over the place you do two things:

You create the possibility of ground loops, and you just waste more time and money.

Why do you think that the negative of the battery is run to the car body? Because it is the best ground available (its everywhere). And due to material properties of the metal - its continuous, therefore voltage differentials should not exist. This is why all of this quackery with grounding kits (IMHO) is just plain malarky! As long as there is a place for current to flow - through the body or the factory wires - than you are just wasting your money. Its called the placebo effect.

The only positive thing I can see from this is if the joints where the frame is welded together are rusted, corroded, or weakened. Quite possibly another thing that I can see changing the ground wire out is if you are running a high output alternator / battery system. Than I see the possibility of this helping since there is an increased current output. Other than that the cables provided from the manufacturer have more than enough ampacity to handle the factory current returning to the battery and than some.

This does not prove anything. There is no statistical data which shows this. This is purely a subjective statement. I can claim that my "internal antenna" for my cell phone works as well just by saying that I've sold over 100 of them. But everyone knows (or should know for that matter) that it is a hoax (subnote - in fact the company who manfactures these devices has been sued by the FTC for misrepresenting their product).

Just more uninformed public. Look at lemmings, they all run off of a cliff too, following the first one. Why? Because they don't know any better.

I'm not ripping on your product (or trying to start a fight) - this thread was started in the "tech" section of the forum, not the GB section. I am trying to inform the general public (ie readers) that there simply is no need to do this (unless they have updated the charging system of their car - and even than only the factory ground wires).
