No, but for $50, why not do it? I did, and have no complaints.

Did the e-bay kit match what CanZoomer shows, with one point to point and a daisy chain for the rest?
Were you happy with the kit's quality? |
I made my grounding kit for less than $30 bucks. If you got a little time, its cheaper just to do it yourself. Spent 15 bucks on gold plated connectors and 12 bucks on wire and 2 bucks on plastic shrinkwrap for electrical connections. Bought monster cable grounding wire. used 8 gauge wire....soldered the ends to the connectors and that was it. no big deal.

The kit sounds good, 4 gauge wire with gold connectors. Probably overkill, but if you are adding extra ground you might as well go all the way.

I did get just a little creative with the final routing of the wiring as opposed to the instructions provided. I must say that the instructions he included were really good. Were you happy with the kit's quality? Very much so. If I wasn't, I wouldn't recommend it. Actually, if I wasn't, I'd probably be "slamming" it, and the guy who sold it to me. :D What's that saying about "...the horse you rode in on?" -Doccable |

Another question for doccable..
The eBay kit (seller: z327) says the terminals are 5/16". Did you have to drill out some due to larger bolt sizes? See... https://www.rx8club.com/showthread.p...threadid=17339 |

Thanks! Great pic!

I made and installed grounding wires as per CZ's illustration. I used 4 gauge braided wire obtained at Home Depot and heavy duty connectors found at a local Ace Hardware. I made four individual wires rather than try to get two of the wires into a single connector. I figured it would be easier to put two additional connectors onto the various bolts than to get two wires into one connector.
Everything went fine until I noticed this noise. There is a clicking noise that varies in frequency with RPMs and increases in level with load. At idle I don't hear anything. Rev the engine and I hear a faint clicking. When driving, the sound level goes up as the load on the engine increases; if the engine is pulling and I leave off the gas the sound stops; step on the gas and the sound comes back. My first thought was that it was coming through the radio, but it's not. I removed the two grounding wires from connection A4 (left fender), connection A3 (engine ground), and connection A2 (right fender) and the noise WENT AWAY. The other two wires were in place. I put the wire back on between A2 and A3 and the noise CAME BACK. I made sure the wire wasn't touching anything that would transmit a noise from the engine to the body; the only thing the wire was contacting was the two connectors. The noise sounds like the noise a fan would make if the blade were hitting something. It also reminded me of a bad spark plug wire that was arcing to ground, but I don't think it is electrical. Could the noise be coming from the fuel injectors now have more travel because they are getting a better signal? The injectors would have a signal that varies by RPM, but would they get a stronger signal depending on load? After two days with no response, I've opened a new thread at Tech Garage on this subject. |

Noise after installing grounding wires
I made and installed grounding wires as per CZ's illustration. I used 4 gauge braided wire obtained at Home Depot and heavy duty connectors found at a local Ace Hardware. I made four individual wires rather than the layout shown. I figured it would be easier to put two additional connectors onto the various bolts than to get two wires into one connector.

I am not experiencing any issues with it, but you might want to check the the ground going to the engine is not hitting anything. Since the sound frequency increases as your rpms do, you might be hitting a belt or something. If you are still having problems PM me and I will post pics of my grounding install and highlight the areas I think you might be having a problem at.

So Doc, are you noticing any improvement in performance?
|
Not really, except that there was a noticable lag at 6k, then around 7.5k RPM. The lag is still there, but nowhere near as noticable. It's difficult to explain, but I can say that as far as a $50 mod goes? I can't complain. Now, when I finally get around to the stage 1 mod... I do expect a difference, especially for $750. :D

Here's the latest...I made a 5 inch long wire using some 10 gauge wire and two connectors. I connected one end of the new 10 gauge wire to the engine ground bolt (along with the wire that is installed there by the factory) and connected the other end into the original grounding wires that I made earlier.
The sequence of events were these: 1. With the four grounding wires connected as per the diagram in CZ's post, remove the connections at the engine ground. 2. Connect the new, 5 inch long wire and the factory installed wire to the engine ground. 3. Using a spare nut and bolt, fasten the new wire and the two grounding kit wires (removed in step 1) together. After doing this I no longer hear the funny noise described in my earlier post. My conclusion is that the heavy wire I'm using is transmitting the noise from the engine to the body and that the lighter wire doesn't transmit the sound. I feel that degradation of the grounding kit by the short piece of 10 gauge wire is minimal and plan to leave it this way for the time being. In the future, if I find a 4 gauge wire that is more flexible than what I currently have, I may replace the two wires that connect to the engine ground. |
IMHO - This why it is very important to use a high quality 100% OFC cable like you can get at a high end car audio shop or Ebay or Parts Express.
You won't get the same results and you may have problems like the one described here if you use cable from a hardware store or electrical supply. The company I work for designs and installs power supplies for central offices, Sun servers, Cray computers etc... When we do a large system install we always use 100% OFC high strand count cable. It has to have very low resistance and be very flexible. Its not the same as the audio stuff. Its much more expensive, but that is how I became aware of the type of cable needed for a grounding kit. |

Ok, well I installed my kit yesterday. Got the exact same one as Doc, so I won't post another set of pictures as it looks exactly the same. Coupla comments...

crf3629,
Don't know why no one has responded to you. Although, I don't have an answer, maybe no one else does either. But I'll try. Have you tried to remove your grounding cables and check for the noise? Then reinstall them. Make sure you keep the grounding bolts tight. Don't know the torque, but they seem to be quite tight. Maybe there is something incorrect about your home made cables. Don't know, just a guess. If it is, you may want to consider one of the kits mentioned on this thread. Good Luck crf3629. Al |
