That much cable is not cheap. Why do you want to do this again? There is not a simpler solution to prevent water from getting in? Seems a little drastic.

$100-150 for cable. Other than a snorkel out the side of a truck I don't see a better way. If I move the batteries I can move the airbox next to the firewall and hopefully draw air from the fender instead of from the bumper.
Well add another $150 for battery boxes. I don't mind doing this stuff as long as I can do it right.
Why not just switch the batteries and air box and put the batteries right on the core support like the super duty does and put the filter further towards the firewall now that the battery isn't in the way
Well when you put it like that, I don't know.
2/0 from the batteries in the toolbox tied straight to the starter and wherever the original ground strap ties to the frame. Should be more than adequate. Moving the weight back that far will be a bonus for the offroad gofast I would think also.
4/0
Why are you still here?
Because I enjoy pissing you off :flipoff2:
And I know a thing or two about electrical systems.

anyone can google, hotpocket. 2/0 is overkill, but that's what I would use.
That chart doesn't say 4/0 anywhere on it...
I couldn't imagine trying to snake 4/0 through a vehicle. I like sparlings idea.
Ive done it on old Southwestern Bell trucks when we were installing big inverters. It's a beeotch for sure. We installed two extra alternators on them, it was a pretty peemp setup.
Look up resistance per foot, figure amps required, calculate voltage drop
Take voltage drop multiply by amps required and that is the heat put out by the cable. If its too high to air cool resistance goes up compounding the heat generation and catching fire
Or take off the shop vac filter that probably isnt doing anything for performance or filtration and problem solved
