Default 12 gauge or 14 gauge wiring?

Hi everyone...

I've been thinking lately about rewiring my car with 14 gauge wires. Most electronics these days are done with 12 gauge, but my old KO speedy had 14 gauge. I prefer the 14 gauge for general neatness, but if it's going to sacrifice overall performance, then I wont go down that road.

What are your thoughts? Any findings? any input?

Thanks in advance!

i went from 12 gauge to 14 gauge, and didnt notice any diff at all, i race in 27turn stock brushed, I think in mod it might make a diff since the more amp draw of the motors.



My theory for changing was based on the brushless sytems
as they all run 14 gauge and them still pull heaps of amps.

And if it was noticable i am sure the high end brushless systems would come with 12 gauge and not 14 gauge. correct?


also 14awg is lighter and easier to work with (providing you get the right brand)
, novak 14 gauge is called super flex but i think it is stiffer than deans 12 gauge.

I think Losi asnwered this above. To be fair you could go to 12 if your using mod as it will certainly transfer the voltage better, but to the point where you simply would not notice it.

14 is just easier to install as well and I have always found a neat car is easier to work on if you get a fault.

check around the pits to with the top drivers, see what they are running to

9 times out of 10, 14g will install easier and neater and perform flawlessly. I'd only use 12 for some crazy 14.4v tractor puller or something.

There should be no noticeable difference in terms of performance between 12gauge and 14 gauge wiring.

I used to use 12 gauge and switched to 14 when i went 5 cell to save weight.
With 5 cell didnt feel any difference, but with 6 cell and hot engines (3,5 and 4.5 BL) i did notice the wires got warm, wich didnt happen before.
Given this said, i didnt really felt any power loss.

For stock 12 gauge seems overkill to me.

Thanks everyone for your input. It's exactly what I thought... just thought it would be nice to have another opinion (or six!). Thanks again... 14 gauge it is! We'll see what happens from here!
