Anyone here with a grounding kit, either black betty or homebrew...
I hear claims of better throttle response, a louder sound-system, faster transmission shifting, possible power gain or feel, maybe more benefits?

Is this for real, not in theory, but are you guys really experiencing a difference on a new G?

Just wondering if the kit is worthwhile.

Thanks guys

 

Yes to everything except the power gain. And I am a skeptic by nature

 

I have Black Betty's GW and here is my short take on it:
1. Better throttle response: Yes, especially in D, less in DS and M mode
2. Louder sound-system: No, I did not notice
3. Faster Transmission Shifting: Yes, especially in M. Shifts b/w 1-2 and 2-3 are quicker
4. Power gain: No, grounding kits are not designed for that purpose
5. Other benefits: No, I did not notice

Plus under G35Robby's post about the Black Betty GW, there are a ton of reviews embedded in the thread

 

pretty honest answers.

 

heres my review:

Louder system, I say its very possible because you are improving current flow.

Shifting better? My guess is the TCU being grounded.

Power gain, not possible. All you are doing with a grounding kit is ensuring proper, good, and better flow of current to the electronics in the vehicle. Something as simple as scratching off the paint and having direct metal to metal contact will also make a huge difference.

 

^im going to be doing that, because its still over the paint.

Also, it is true and i have said it many time.
This does not give any power. Now even 0.1hp, NOTHING.

The shifting does get quicker and smoother but it doesnt mean the car is faster. Might feel like it to you but thats just you lmao

 

Thanks guys, appreciate the feedback.

It's not that I'm cheap or anything, but I hate to get excited over something, put it on, and then feel like I wasted my time.

Thanks Robby, your thread pretty much says it all.
On that note...
Does anyone also have the throttle body grounding kit, is this going to help any?

 

I just put on the kit on my 08 G and the kit had the grounding wires and the throttle body wires. The throttle body wires help the throttle response and I've also have had all improvements listed above. It was a good investment in my opinion.

 

I bought one, installed it, zero difference. It's gone.

 

I had one done from a member on here and just noticed the copper wire inside was turning black. As far as gains I think it overall made my electronics better. I went with a second battery for my system because it was affecting my car's transmission when it hit the lows.

 

heres mine

so whatever one you get it will help out.

 

these types of mods make me laugh

 

The ring terminals? I'm guessing oxidization? I use tinned copper (not to be confused with copper plated) just so that it protects the copper from oxidizing.

 

Have you ever done them? I can GUARANTEE you that it makes the electronics much better, especially if you have an audio setup. Lots of audio guys do this, however its only 3 wires and it's known as the Big 3. You run a wire from the battery positive to alternator positive, battery negative to chassis, and battery negative to engine block.

Many people use 1/0, but it's actually not necessary. 4 awg is sufficient. It definitely helps with voltage drop and is the FIRST thing to do as far as an electrical upgrade with doing an audio setup.

The next thing depends on how severe voltage drop is. You can either get another battery such as an Optima, Kinetik, Odyssey, Powermaster, Deka, Northstar, etc... I prefer Odyssey, or you can get a high output alternator. If you're going for a system that needs lots of power, around 2k, maybe 1.5k rms or higher, or using amplifiers that draw a lot of current, both would be best to go with.

The final thing to do is add another battery or several batteries in the trunk.

Notice how I didn't mention a capacitor...that's because they don't do anything. It's a bandaid and if your electrical system is not up to par, it's actual an extra load on your electrical since it doesn't charge fast enough to discharge, that's why a battery is better. The only purpose for them is for looks or if your electrical is already good, but if it's good, why waste money on it?
