View Full Version : grounding kit for an A4(2.8)?

02-26-2005, 02:13 AM
i was wondering, after reading the newest Tuner Performance Reports magazine, i was wondering if there are grounding kits for our cars, if so where can i purchase one? would it work well? i have a 98 2.8. [a4]

I think Audi designed the car well enough you wouldn't need something like that.

even if they didnt, you dont need a kit, you can just get some 4guage wire and make your own kit...

uhm, i've got to hear what the latest tuning fad is. what in the world is a grounding kit? is it so you don't spark your nos tank into blowing up?

Grounding kits have been around forever. It was much more purposfull when throwing a highvoltage ignition system on an older musclecar/truck thats wiring sucked from the factory. There wasn't a need for great grounding back then because not much was electrical and the ignition systems were weak. I'm pretty sure most kits just give you some fancy looking wires to re-ground your motor body and battery together.

^^^ yeh what he said

A4Shon1.8TQM: so you are saying that you get 4 gauge wire and ground it where tho? i thought it wasnt the body, some other source?

I wouldn't do it. the electrical system in your car is grounded well enough that you don't have to do this...save your money and do a real mod like a chip/exhaust/turbo upgrade...stuff like that.

i have seen them on ebay made by HKS NGK has a pair of them out there also i would get it

02-26-2005, 01:32 PM
can you provide links? i looked in hks website, ngk website but i found nothing.

02-26-2005, 03:09 PM
HKS doesnt make one for our cars in terms of grounding, and NGK making a ground kit...doubtful.

Why not just get a generic one, theyre just wires. Expect a .5hp gain though, if you're lucky...I doubt it'll do anything.

02-26-2005, 03:12 PM
yeah I am still not seeing the point in buying this grounding kit

02-26-2005, 03:23 PM
but did anyone actually tried it? im not really going for it for power, much rather for longetivity of the car and just to help the car in general. i mean it cant hurt the car tho right? maybe jazz up the engine bay a little with some colorful wires =P and plus they are not terribly expensive either.

but why?? spend your money on something else that the car will gain something from

I can see it helping if you have a big stereo
its called "The big 3 mod"
upgrade the wire from
alt. to pos of batt
alt to chassis
neg of batt to chassis

the thought behind it is if you have 4,1 or 0 gauge wire going to your amp but only 8 or 10 going from the alt to the batt the alt cant meet the demands

02-26-2005, 07:56 PM
ok in that case I MIGHT see why one would do this

My ricer friends all do this mod...

02-28-2005, 02:50 PM
because it helps a lot for hondas... i think they dynoed like a solid 5-8 hp increase in a civic del sol, just wanted to try it on the a4 tho. maybe i'll start a new fad...lol

02-28-2005, 03:46 PM
well, theres 3 main wires that usually get upgraded...

battery (+) to alternator

battery (-) to body

block to body/frame

edit** i did it on my truck and it helped out a good bit...

but i was running a pretty hefty stereo...

i dont know that it will help you... i know i wont bother until i do a stereo in this car...

i see...

I replaced the cables on my Jeep, but they needed it, one was all but rusted in half...

why not get a clamp CT for a multimeter and see what kind of current your running through the cable to see if you need one?

your headlights will get brighter. thats all that happened on my friends car.....

probably a more accurate test would be a voltage drop. Turn on as many accesories as you can(rear defrost, high beams, blower on high, seat heaters, radio) bring her up to 2k rpm and measure the difference between the neg batt post and eng block, body wherever you think you can mount your new wires. The check the alternator wires in a similar fashion.

More ground wires can't hurt. Except for the .5lb weight gain will decrease your 1/4 mi times. But the increase in electrical efficiency will negate this.[:p]
