I've swapped out my starter to a mini CVR hi-torq unit. Also relocated the battery to the trunk (Optima battery and BMR bracket).

Just wondering what gauge wiring I should use to run from the starter to the battery.

I was thinking of using 10 ga wire.

What do you suggest? Do I need to go this big with the wire?

 

0 gauge

 

Why such a big gauge wire for a starter?

 

Starters pull alot of current.

 

yep

 

if you run a 10 wire for the starter you better have a fire extinguisher handy
you can run a 2 gauge wire if you are woried about weight if not use a 0 gauge wire

 

0 ga it is...thanks guys.

 

I use welding cable
holds up to heat, and weather plus its very flexible
and can be bought at any welding supply and the usually have the ends youll need
also I solder the ends on
the way I do it is lock the end in a vise heat it with a small torch and feed in the solder when you have filled the end up about 3/4 of the way remove the heat and stick the wire in and hold untill it cools then shrink wrap the end

 

I understand why you would use welding cable, but why would flexibility matter in an application like this?

 

I use it and it works well

 

due to temp changes that the car goes threw and the flexibility of all cars the cable will always be moving a little bit each time the car is driven.

 

Ok, fair enough.
