Anyone tryed these http://www.groundingkits.co.uk/ are they any good. Possibility of a group buy if they are.

You really don't need to use the poncy audio-style cable that he's used, but the idea has some sound principles.

Not really, for the main engine block earth.
The thicker the cable, the lower the resistance which, is what your actually trying to improve one. Electrons flow over the surface of a cable so, the higher the surface area, the lower the electrical resistance will be. And 30 amp cable, isn't very heavy duty. It's maybe 16 AWG, about as thick as the mid sized cable under the bonnet and certainly nowhere near as thick as the alternator, starter motor or main earth cable !stumo said:
Yep, we've been through that !stumo said:
As above, it's the resistance between the component and battery you're trying to improve on.stumo said:

So why not just use massive wires....the earth will spin smoother and your car will make 400 more HP....
All you're trying to do is to create a level playing field where the difference in voltage between the various earthing points around the engine will be in millivolts not volts, the current will be negligible. you don't need a big wire for that amount of current.

Didn't take long did it.... Can you ever post a reply without something idiotic and worthless in it ?stumo said:
And there's no need to use 'massive' wires as, we're only talking about 14.4 volts, and fairly low current !
Actually, you're trying to drop the voltage difference to 0 volts. Millivolts will still cause issues. Although, of course with the age of all the cables on the GTiR, that will be nigh on impossible. So, ultimately, the least resistance between the electrical components and the battery, the better !stumo said:
Nope, it's the Earths core and magnetic forces that make the world go round ! ;-)stumo said:
And I don't think 30amp cables are 'huge' ?!
Once again, because the thicker cable presents a lower electrical resistance. Exactly what you're trying to achieve by reinforcing the earth bonding. And 30 amps isn't exactly high current, is it ?!stumo said:

I've got a spare grounding kit with gold connectors if anybody is interested.

So if there's a potential difference of millivolts between two earthing points ( for instance one on the plenum and the MAF) do you really think that using a 30A wire will make any more of a difference than a 5A wire?
Don't forget, we're talking about a PD of millivolts.
30A current is quite big on a car, it's certainly capable of melting smaller wires and flattening your battery pretty quickly. Have a look at your fuses, how many are rated at 30A or higher? not many....

Of course not. But, we're not just talking about the lower current draw components, we're also including the alternator, starter motor and lights etc...stumo said:
a 5amp current could also melt lower rated cables, and drain the small GTiR battery fairly quickly ?!stumo said:
Again, I'm not saying that the cable will need to carry 30 amps, in all cases, just that some components you will be reinforcing, will !
