"That which we don't/won't understand, we rail at"

I deal with Radio Frequencies all the time. Proper grounding is a MUST. What frequency does the ignition system operate on? Well I'll be darn, it RADIO FREQUENCIES.

 

I'm trying to explain it to you guys, don't rail it yet.

 

see edit above, your too fast...

 

Current spikes in the RF range due to ignition events are bypassed locally in the high voltage generation hardware. They HAVE to be since your big fat long power and ground wires running everywhere look like big fat inductors in RF land. But you know this, because you deal with RF all the time.

Let's entertain a hypothetical situation. Assume that for some reason that the stock system was so poor that there were differing ground offsets across the various engine sensors, and installing one of these hyper type R super racing grounding wire kits reduced or eliminated these offsets. Why should one assume that this will increase power? All you've done is changed the sensor output from that in which the car was tuned and calibrated by Infiniti. All one can say is that it will likely have random effects on power output, some positive, some negative. Although if such ground offsets existed, Infiniti would have quickly noticed this and changed the electrical system accordingly. After all, they have to warranty the car, and the last thing they want is an engine misfiring or running lean from bad sensor readings.

 

No hp gains are claimed for the G...

 

For the same reason that switching from a standard to a high powered ignition system will give you more power. Hotter spark, more consistant spark= more power. Just changing the plug wires on my Grand Prix made a difference. It wasn't missing, just forming corona discharges that bleed off power. A grounding system "evens out", if you will, the ground potential of the engine compartment.

All I'm saying is that you are one of the FEW that has "poo-pooed" it and you haven't even tried them. If you try it and still have the same opinion, then you can bitch.

 

Guys, you really need to listen to yourselves. "Grounding wire mod" is almost exclusive to these cars. I've been around, and modding cars most of my life, and this is a first to me. Don't you think this wouldn't have been brought up 10 years ago...5 years ago? How bout now? I am on several different forums currently, and this mod is non-existent, except here. Oh, and this is my fourth VQ, and this "magic mod" has never been suggested previous....

To me, this sounds like a marketing scam that someone is laughing about right now......I hope I'm wrong, but I doubt it.

Lick your wounds and get out....

 

Well it does sound a lot like the V1 vs 8500 debate. Some of us here are "Masterdebaters".

 

Hey Dave - I have nismo ground wires and notice a little difference in the shifting but nothing major. I'm a bit interested in some of your mods. Does the spacer do much, did the z springs lower your car more in front than the coupe springs in rear and how's the ride, would love to see some pics of your blacked out grill. Thanks man.

How about the responce in shifting MM? I'd have to press up and down two or three times to shift?

 

I was really skeptical bout the grounding wires too, but i decided to follow all the hype and get the 10 wire performance grounding kit. I had doubts about the grounding wires doing anything and didn't have any expectations either. I just decided to buy the kit just to dress up my engine bay a little bit, and if it does do something then great !

Well after installing my wires and resetting the ECU and doing everything else everyone says you should do. I started up my engine, and low and behold my idle drops like crazy not to 650 rpm like everyone else but just to around 850. This was from a cold start too, so I know the grounding wire kit had to be doing something...After seeing that happen I wanted to see if my shift times were more quicker and on cue like everyone else says. (BTW: I got a 2004 5AT). Well I took it onto the road and at the first light my car starts to shake like crazy......I'm guessing this was just because my ecu was readapting or something.. but like it stops so nothing to worry about. I then got onto the Highway so that I can test out these wires at WOT. Well the shifts did seem to shift a little quicker, but nothing drastic enough to claim that its almost instant. The number of the gear you are in on the display does change the instant that you push the transmission into the next gear though, but the gear actually still shifts like a quarter of a second after you see that number change.

So all in all, I don't know about all the other grounding kits out there, but gordgee's 10 wire kit does do something, but to me it wasn't as drastic as some other people have stated online. And personally I wouldn't go for that ebay kit, cuz I doubt its even the real NISMO grounding kit...If you were going to get a grounding kit, I would honestly just do it for the looks, since I doubt performance wise it does anything that isn't negligible, it sure does look nice in the car though ! ...just my two cents.

 

Unless your looking to improve you stereo system to a really high end setup I wouldn't waste my cash. My past grounding kit add to my old 03.5 G35 sedan and my friends 03 G35 coupe proves (too me) you will not get any significant gains with a grounding kit. So, for this subject I'd say if it ain't broke don't fix it! Unless you have extra money and time that is and want to dress it up!
The only mod that makes significant gains in HP and Torque is a supercharger or turbo setup. Otherwise you just get minimal gains from the typical CAI, z-tube mods most people have. It does sound better with these little mods though!
Totally up to the individual as to what you perceive as significant though.

 

It's not exclusive to these cars, and there WERE grounding kits available for other cars 5 or more years ago. It's a very common mod for a lot of cars and is in no way some clever marketing scam. If you don't see any reason to put it on your car, then don't; but don't shoot down a good mod because you've never heard of it.

That said, I'm ordering my GroundingGear very soon

 

I'm wondering if just a ECU wire and a TCU wire would help the shifting "times". I like the idea, but I hate the execution (wires running around under the hood??)

 

Yes...I have the 10-wire set w/ those 2 wires, and the net result is quicker shifts in Auto mode. I'm not very car saavy/technical and I was able to do the install myself without any problems.
