I know almost everyone on here has a lot of audio/video in there car but never hear any thing about aftermarket grounding packages. I mean the kind you can get off of ebay and other auto stores. Ive heard they actually work to, better ground as it distributes the neg. charge better. I know a couple guys at diamanteowners have em but dont know if any one on the "other side" :bowrofl: has em. Talk to you later guys.

The aussie "performance buildups" mag a couple of months ago had a write up on a aftermarket 'earth' kit - which they incidently tested on a TJ Ralliart Magna. These guys are pretty serious performance tuners (both V8 aspirated and hi-tech), and stated that in the beginning they thought these things were a P.O.S (keeping in mind they were actually testing the 'performance properties' of such a system).

They dynoed the car, then fitted the kit, dynoed it again and had picked up 4kW. They then played around with different earth points in the engine bay - and managed to eventually pick up 8kW above the first dyno figure.

Needless to say I was very interested to read this - especially for the fact that these results were achieved on 'one of ours'. I made a mental note - and am considering at some stage in the not to distant future, taking the mag down to a local performance tuning shop and asking their opinion on the results - with a view to seeing if they can be replicated on my vehicle.

If enough ppl are interested - I'll consider scanning the article and posting up in this thread...... I hate using the scanner, so I wanna see some EOIs before I'll plug it in.

As far as what these kits do for a vehicle with heavily modified ICE - that's not my area of expertise, sorry.

I'm interested for sure :P


p.s make it X10 if no one else replies with interest lol

Was this just an off the shelve setup?? What brand, where are they available??

From memory it was called "black earth" or "sun earth" or something...... I'll scan the article this afternoon - cause I know it sounds unbeliveable. Check back in a about 7 hours....

you can get these things off ebay pretty damn cheap 2. And also not hard to install at all.

Install time is prolly an hour.

Interesting - did they give a reason as to *why* it gave a performance increase?

Would be very interested to see the article...

i dont really rate them. if it were that easy why wouldnt manufactures do it? plus i have tried and had to make custom earths for many cars, its definatly no merical fix for 8kw (unless you have faulty earths atm)

Okay - here it is....... my recollection wasn't entirely accurate, but I'll let y'all read for yourselves and discuss.....

If you found this article worthwhile - I recommend purchasing Performance Buildups magazine available from all good newsagents (not that issue tho....)

erm..


first image, middle column, bottom paragraph:

"Now hungry for power, we pulled the air turbo from the intake and ran it up again,..."

what's he talking about? air turbo?

oh, an earth kit is just a bunch of thick cabling like, 4ag or even 0ag cable isn't it?

I believe they were referring to the factory snorkel which funnels air from the upper grill to the airbox - there is a pic or two showing it removed from the engine bay. Hard to believe they picked up kW by removing it - I guess it would only work in a dyno environment with the cars bonnet up and the fan blowing into the engine bay.
