I don't see an electrical section so I'll ask it here, about all the wiring you see is CCA, how much do you loose on long runs with this wire. For an example, say you need to run an 8 gauge wire to the rear of the car, 10 or 12 ft, how much drop will you see? Fans and fuel pumps would be affected more than head lights and such and I'm going to need several feet on this car. I'll get a universal wiring harness for all the normal stuff but I'll have 2 electric fp's and a big amp alternator which will have to be wired through the kill switch.

The rule of thumb for wiring using aluminum or CCA is you need to go one size larger than with copper. This will eliminate any concerns about voltage loss, or current carrying rating. So if you need a #8 you should use #6. For a battery cable from trunk to starter I'd use 2/0 CCA.

I was just curious. This was new to me. I found this article.

What you should know about CCA and OFC Wire

Copper Coated Aluminum (CCA) and Oxygen Free Copper Wire Purchasing wire can be confusing. In addition to gauge and insulation type, we are now seeing designations like “CCA” and “OFC” applied. This article will attempt to clarify a few of these....

That's some good info. You got to watch on some of this wire, you have to really dig through the description to see that it's CCA.

Agreed.

CCA is mostly used for sound systems in cars where they have large current draws, but want to save weight. But if sized properly it works well for remote trunk mounted batteries, and is better than plain aluminum wire.
