scoob fae ork Posted July 13, 2008 Posted July 13, 2008 (edited) As above really. would they be any good on a 2004 UK STI ???? Edited July 13, 2008 by Scoob Fae Ork
st3ph3n Posted July 13, 2008 Posted July 13, 2008 You have to ask yourself - are you modifying now for modifying's sake? Is there anything wrong with the earthing on your current car?

Would there be any benifit to change it ??
st3ph3n Posted July 14, 2008 Posted July 14, 2008 I remember someone saying to me they were just snake oil and didn't really do anything at all.
emoe Posted July 14, 2008 Posted July 14, 2008 Earthing kits are great for older classic cars, mainly because the earth straps that connect the engine block Etc to the body and chassis, and the battery to the body can corrode over time and obviously corroded straps create more resistance. The school of thought is that more resistance crated a less-hot spark, and other ancillaries suffer. In my personal experience, racing and road, bad eaths cause the lights to be a little dimmer, or not fuction correctly, but unless your car is running like a dog BECAUSE of lack of adequate earthing, then youll notice NO difference, and its just for show. Your 2004 model should not need an earthing kit!!
iain_ogston Posted July 14, 2008 Posted July 14, 2008 I have a combined earthing and voltage stabilisation kit. Can't do any harm can it! Only noticable benefit is that lights are steady under all driving conditions.
emoe Posted July 14, 2008 Posted July 14, 2008 Thats your voltage stabiliser! Most Alternators have a Voltage Reg on the back of them and theres another in the car somewhere, (changes from car manufaturer) Standard VR's basically try to keep the volts and amps at a consistent level, to avoid blowing bulbs, and electronics, but their tolerances are +or - 3 volts or so. Most that we have tested run from 12.2v idle, to 11.5v with lights idle up to fluctuating 14.6 to 12v at 3k rpm. The amps are a bit better but that fluctuation is what you see in the lights, and the guages. Having a decent aftermarket one is a definite benefit, as youll see a good voltage consistent across the rev range, meaning the guages, the electronics and the lights all recieve the most stable voltage possible. So again, an earthing kit will do NOTHING, unless you have screwed up earth cables and badly corroded straps. Spend the money on a good aftermarket regulator.
scoob fae ork Posted July 14, 2008 Author Posted July 14, 2008 Thanks for your help guys thats made things pretty clear to me dont think al be bothering with that until the car needs it me thinks
iain_ogston Posted July 18, 2008 Posted July 18, 2008 My voltage sit at the same level irrespective of driving conditions/engine load. I've not seen the voltage move at all since the regulator went on (not even +/- 0.1v on the digital readout) Only wired up the grounding wires cos they came with the kit, wasn't expecting any real benefit from them since car is mint. One thing I have noticed is that car starts quicker. Fires almost instantly on key turn - hot or cold engine, hot or cold weather, doesn't make any difference.
