Well ive been looking at the Ground Fusion grounding kits for the tC and i was wondering... Does anyone own one of these?? I am sure if someone has one, and with the measurements we could all make our own custom ones (probably even better!)

Ive heard it makes a difference on the xB with shifting and lighting but does it do the same for the tC?

Is the grounding loop the same?

Body To Head..
Head To Coil Pack..
Coil Pack To Bat Neg..
Bat Neg to Body..

And lastly, this is a bit more technical but here goes... Will a 4 gauge cable produce the same effect, better or worse than the commonly used 8 gauge...

If the bigger the cable produces a better effect i might just go totally wild and overkill with marine quality -0/1 or thicker cable...Now thats BIG

Here is something else to think about...

Tranny to Bat neg (or body)

Thanks! If i do the mod il make sure so take plenty of pics on how i did it all

 

i ummmmmm have both.

4awg groudnfusion kit along with 1/0 big 3.

 

Do you mid snapping some pix for us? Maybe even explain how and what you did what you did...

Did you notice any improvements with the electrical system? or performance?? thanks for your help bud!

And by the way what do you mean the big three?

 

you will get zero effect outside of possibly helping your audio system a little. So dont go into it believing the "it will make your car run better" crap.

If you are going for high powered audio, you really just need one good ground for the amps. But if you just want to dress up the car and think the ground kit looks nice, then it really wont matter which size since you wont get any real benefit from it.

Now, from a purely electrical standpoint, regardless of actual benefit, a larger ground is always a better choice. Larger wire has less resistance per foot, and keeping ground potential low is what you need to do, which requires low resistance.

 

^agree

it in no way helped out anything witht he cars runnings. I got it for the audio system.

in that aspect is works quite well. A friend is running 1000 watts RMS between his amplifiers in his tC, and I'm running a tad more than 1400. His headlights and gauge cluster dims horribly when he turns things up. Me on the other hand, i get only slight dimming even when cranked up the entire way.

 

Looks good.... what are the grounding points??

(off subject but do the new tC's come with plug wires or are tehy individual coils?)

 

Coil on plug ignition. VERY good setup and comes stock with Denso Iridium plugs. One thing I would never change about this car short of buying a step or two colder if going FI.

 

all tC's are coil on plug, regardless of year.

i got the nology's just so i can say i have another mod (that and i got them for $50 brand new, so...)


grounding points for the big 3=

postiive-> alternator
chassis-> negative
block-> chassis

 

ok im definitely a noob at this too... so i have to ask... in Neo's pics... there are blue grounds everywhere...
does this do the same thing?

true story.

 

sorry to keep bumping this but... The xb guys have experienced better idle as a result of the ground kit and better shifts for the autos... i am not expecting an extra 100hp out of the mod but does it help out any with the idle or shifts on the tc??? Even the slightest minuscule (but noticeable) bit?

 

If you think it does, it does. Buy yourself 25ft of bulk wire and a bunch of ends, and go to town. So long as you feel it's worth the money, it is.

 

I put ground wires in after I got my stereo system put in and it didn't help at all. It actually messed up my electrical system. My windows wouldn't respond properly and I would quickly lose power when lowering them or opening/closing the sunroof. My passenger side window went dead too. I took off the wires and the car is fine again. So unless you have a really powerful amp or more than one amp, don't bother with the wires.
