Grounding kits...

[Spades]

ok, past all the hype....do grounding kits really do ANYTHING? Other than look pretty that is.

The theory is that the better the ground the better the engine will run ect...but can someone please explain how a better ground to the engine can result in HP gains or a better running engine?

If it really is a noticable increase I would definately install one or fab my own, it just doesnt make alot of sence to me.

The theory behind the grounding wires is that it makes the whole electrical system, and thus, the ignition, more consistent, and allows for a more powerful spark- thus burning more of the fuel and air that mix in your combustion chamber.

Don't expect any huge gains, though- it's usually a 1-2% gain.

ok, got it, thanks for the help moose.

You can't feel the difference, but the logic makes sense so I'll leave mine in place.

[ChinoCharles]

Its a good thing to have for the price. 'Nuff said.

As always,in combination with things that net small gains add up to alot,you save your pennys dont you.
And Chino is right,for the money,its a must have.

If you absolutely have to buy one, get the cheapest one you can. please don't buy a "jdm" or blitz or whatever japanese brandname they try to sell you for 3x the price. just get the cheapo ebay kit for 20-25$.

they all do the same thing! you would be buying a sticker with the name of the "jdm" brand on it.

TRUE DAT!!!

Good for da sound.

BOom boom.

the current has an easier flow...less resistence across the circuit. This is the FIRST thing you should do for a sound system setup. The second thing would be to put a nicer battery in the vehicle.

Got one in my car, i have to say that it's really help, but maybe it's just in your head. But i'm satisfied for the price.

But my dome light kinda blinking when the doors open. Is this normal?

[Spades]

well, I made my own yesterday. fabbed a steel bracket that connects to the nagative battery terminal. I am using 4 gauge stereo-style ground wire. I am connecting the grounds to the rear firewall next to the ECU, the starter, a ground point next to the throttlebody, the alternator bracket, and the radiator support. The cost? 0 dollars. It was made using wire I had left over from previous stereo instalations, and the bracket was made from scrapmetal I had laying around. It probbly is not as pretty as some of the grounding kits I have seen, but I blacked out the bracket and stashed it on the side of the battery housing and I hid the wires so they wont be seen.

P.S. and yes, I count my pennies, I am poor, hence why now I drive a Yaris

EDIT: I am still on the fence about it helping my engine have hotter spark, but, I figure it is good since I have a stereo system and the added grounds will help my starter and alternator last longer.

I'm really interested in this, who makes a good one? (grounding kit I mean..)

Do grounding kits do anything to help with the rough idle while running the A/C? Is there anything to be done for that? It's not very pronounced, but if I could get rid of it, I'd like to.

Not hotter, just more consistent.

I may just have to start whipping these up. Should the distances between grounding points in the bay be the same for the Sedan and Liftback?

Should be- I mean, really, a grounding point is the same no matter what kind of car it is.

SOMEONE DO A DIY!!! please...

and will it help my 03 Corolla on that weird idling speed???

I just changed my plugs,cleaned MAF,replaced Tranny oil,flushed/replaced oil&filter with synthetic mobil1,cleaned and re-oiled the reusable filter, cleaned throttle body,ported polished and high heat painted header,raised the idle speed to 900rpm, and still it seems to go back...
Also I checked my battery,checked for engine code and alot more stuff....

[ChinoCharles]

I know, but I've been surprised by the differences in the two before. In theory it shouldn't be any different from platform to platform as long as it has the 1NZ.

[ChinoCharles]

For those of you complaining about the rough idle, I switched over to Royal Purple 5W30 full synthetic today and it was idling smoother. Just an idea...

[Spades]

well, from what I read in the DIY and what I know of mechanics/electrical, I would say good places to ground are firewall next to the ecu, starter,alternator, the throttlebody(its on the other side of the engine away from the ground on the alternator)or somewhere on the engine close to it,and maybe a couple places on the fenders or chassis.

I am really not sure if it makes the ignition more consistent as everyone says it does, but I know it helps the starter and alternator last longer, and helps if you have a aftermarket stereo.

Edit: there is already a DIY in the DIY manual from this site. really all you have to do if you want to make your own, is go down to a local stereo shop and ask if you can have or buy for cheap some of their scraps of wire they have laying around. then make a distribution block from some steel and you are set, all you need is some bolts and metal screws, some light gauge steel, and some 10 gauge+ wire...

prob not. all it does is provide a better current/less resistance to ground. which will probably not help your idle at all.

Exactly, and didn't Chris07LB sell his own homemade kits at very good prices?

[ChinoCharles]

It wasn't Chris, but yes, someone did.
