Grounding Kit for 370Z

Guard Dad · 10-03-2013, 06:19 PM

Was included with my G3 intake as part of a promotion. It's like chicken soup when you have a cold, it couldn't hurt.

But for about $30 and a couple h ours of your day you can do the same thing. Transmission response is NOT placebo though. AT shifts faster with ground kit.

Well the general consensus here is that this is snake oil with the exception of UNKNOWN370Z.

Guard Dad, since you have a 7AT, did you notice any difference with the shifting as pointed out by UNKNOWN370Z?

Yes, but to be fair I've never used one on an automatic car so I can't speak to that point.

I can't honestly say that it made a difference. But I wouldn't rule it out. Here is my take on it:

I have a great deal of respect for Stillen and their products because they are a "real company" with a track record and their products seem to stand up to scrutiny on the dyno and in the real world.

You wouldn't think that additional grounding would be necessary but if your factory grounding is anything less than perfect for any reason this should make a difference. With modern electronics once in a while little things can make all the difference. Perhaps this could be better thought of as a proactive measure to prevent problems as a much as one designed to solve them. If your car sees rain or road salt that might compromise the factory set up the grounding kit could be money well spent.

My car is for the most part a fair weather car that that has only 12k miles in 3 years so I can't talk about track performance and so forth, but my AT7 is a delight and the more I use the manual mode the more I love it.

I neglect using the m mode often because of having to replace the torque converter? I may be wrong but I think i read on here that someone needed to replace X part due to daily use of m mode?

I can't imagine there being any truth to that whatsoever. Most of the 7at drivers here live in manual mode. If it caused problems you'd have lots of guys with problems.

Yeah idk i could be wrong

You can hook up a multimeter and an oscilloscope anywhere you want on the car and objectively demonstrate that the grounding quality is unaffected by the installation of such a kit. You could measure shift time and demonstrate that as well, if you were so inclined.

There would have to be a staggering design flaw for a late-model car to benefit at all from a grounding kit. Modern vehicles have return wires from electrical components rather than remote ground to frame, and have nice fat wires with negligible impedance. Throwing another wire in parallel doesn't make a significant difference in your ability to move electrons.

Any difference that is "felt" is placebo. I'd be happy to lend electrical equipment to any who would like to experiment on their own.

I myself doubt that this item will do any of the claims I've seen across all the manufacturers. That said, I am currently in the process of making my own. I work around electrical components for my job and sourcing what it takes to build one was fairly easy for me. On top of that I believe mine is going to be better built simply because I'm doing it and it's for my car so I'd take more care to make it look nice than a big supplier would.

There is no such thing as "too much" grounding in any electrical power system. Only application I've seen exception to this rule is in some telecommunications applications.

I'd think that with very little research a person could build one of these in an hour and spend no more than $35-40 on it. For that money even if it does absolutely nothing if done right it will make the engine bay at least look nice, any power gains would be a bonus imo.

I'll post pics of mine when I get done with it.

"Too much" grounding doesn't (generally) create issues, but it also gains nothing.

it gains a sophisticated look....

I agree, I mean I'm an electrician and if a customer was to run a single 120v 15a receptacle then proceed to drive a half dozen ground rods in the ground it would drop ohm readings (marginally) but is not needed for the application. But if that's what the customer wants and they got the money to do it...more power to them.

like I said it wont hurt, but the return on the investment would be negligible simply because it's overkill. I feel the same way about this kit. BUT, if a car owner wanted to do it meh its their money. In my opinion it's money better spent elsewhere. The only reason I'm doing it is nearly all my under hood caps (oil, radiator etc.) are all red with silver Z accents so it would just enhance the look. Plus hell I literally can put my hands all the components for free, all I will have in it is my time.

If the gremlins in the motor decide they like the extra grounding and throw me a hp or two all the better.

I certainly wouldn't purchase a pre made overpriced one for what you can get from a dealer though.

Alright....resuscitating this thread for recent feedback and/or experience with installing the ground kit.

From what I've read here and along with other web searches, the majority opinion is that the kit has no effect on actual performance for AT. I already have AAM mid-pipe with short tails and Stillen Gen 3 installed and waiting for the FI HFCs I ordered. After the HFCs install, I plan on doing a dyno tune, so do think it's worth it to install the ground kit?

For the cost of some wire, terminals and heat shrink tubing, it's worth it. For the $100+ companies charge it's pretty obscene.
