Ground Wire kits

[CRE]

how much current is being passed on a lightly modded car? or stock for that matter? I want proof. Big being a relative term, what enhancements can i expect to see on a electrical system that the stock gauge wiring is used, if,in good condition? I will end this with we agree to disagree.

Oh, Stock guage wiring will work fine on a stock car if it's in very good shape.... but, under certain conditions it will act as a bottleneck (such as running the engine at high RPMs). Yes, 4GA is overkill, bigtime, but you're less likely to need to replace it. Even if a cable is capable of handling a certain load it doesn't mean it can handle rapid changes in that load efficiently. The thing is that any length of wire has a specific capacitance and response curve, just like capacitors, beyond those parameters the flow is disrupted and slowed. Personally I'd rather have grounds which can handle more than "normal driving conditions".

At anyrate, I did have some bad grounds and opted for the overkill option when replacing them. My car is more responsive, and my headlights no longer dim at idle.... good enough for me.

bump, yup recycling....

Has anyone purchased the type of kit that was originally posted about?

Wondering if it is worth the $25 or so and hear from people who have tried it.

A friend of mine bought a similar kit for his Tiburon. Personally, I honestly didn't notice much of a difference. I believe that if he had done his own ground kit, it would have worked out much better. The only difference was that the sound system sounded a bit better. Personally, I still didn't like the quality of the kit he bought.

trying to gain performance by using a grounding kit is like an obese person drinking diet soda.


However, they are EXTREMELY beneficial if you have an upgraded stereo with high amp draws.

Make your own ground cables. If you're going to spend money it, do it right.

 

[starscream5000]

The three main grounds that you should do are:

Chassis to negative
Block to chassis
Tranny to chassis

Like ^ he said, redo your "Big 3", those are the most important ones.

werd.

redoing the gnds is especially important on a car as old as the MKIII....

i'm not a fan of a brazillian grounds.....stick to the stock locations, etc. with a large gauge and clean mounting points.

i have an issue of turbo magazine where they dyno test a ground kit on a 350z and it made a 5hp increase across the board I'd buy a ground kit just to improve my ideal lol

bah you bum

quit being cheap!!

 

[theDon]

time is money, more than $25 to me doing it by hand hehe. I'm going to do it custom as suggested though, gotta make wires to reach my odyssey battery.

I was tempted by some nice Taylor racing pre-made lines on Summit but they won't work with the stock wiring out of the box.

how you clean up your grounding points..?

lightly sand the surfaces or what..?

 

[AGlobalThreat]

Yes just general cleaning, I use a wire brush. Make it shiny!

 

[RazoE]

oh fuck it then, I have a few of those things that came in my tool kit..

I'll do it tomorrow, before work..

 

[Wendigo]

Holy Crap Lazurus thread.....I ended up getting a spool of wire and some different sized terminal ends and replacing many of the original grounds....And had plenty of material to make others in the future. Cost: <$10

 

[figgie]

Military use TefZel wire all over the place

 

[Wendigo]

Tefzel?

 

[CRE]

Yup, Tefzel. I've never used it in anything other than wire-wrap applications, but I like it... I don't think I've seen it on any wire larger than 28AWG. Handles heat like nothing else.

We're likely talking about about Mil 22759/16 here, although it's pretty much been superseded these days, at least for aircraft use. I have tons of the stuff lying around. In fact I recently rewired the headlights on a car with new relays and 22759. You can get it in larger sizes. I have spools of 8 on up to 24 awg in my hangar. Come even larger than that. I've seen it in 2 awg.

Fwiw Toyota uses a special kind of bolt for body grounding that alleviates the need for cleaning. I suspect more than a few have long since disappeared on many cars. Also, all but the main and ECU grounds are redundant (multi-point).

As for aftermarket ground kits all I'll say is "There's one born every minute"...

 

[Doward]

I actually changed my grounding points -

Battery -> Block
Block -> Firewall
Block -> Chassis

and of course, one little ground (14ga wire) running to the coil pack bracket.

I prefer to ground straight to the block, myself.
