This would get it done and seems for the price a great deal. ?? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200562225892&ssPageName=STRK:MEWAX:IT thoughts?
That would be great for an amp but for your starter (drawing up to 250 amps) you are going to need some 0 AWG or 00 AWG cable. I opted for the larger 00 AWG cable so I am sure there is no appreciable voltage drop in the cable. (less than 0.5VDC when cranking)
Internet fantasies... I've had 4 AWG in my Buick GN powered S-10 swap since '03 and it never gives me any problem starting. Of course, that's only a lowly 6 cylinder. Running 24 PSI boost. Pulling 12.0's @ 3750# on street tires.
I seem to remember something about using welding machine wire from some post as an inexpensive alternative. Just a thought
My company makes automotive battery cables, just about all of our customers specify welding cable because it's so flexible. I, too, would use 2/0.
Reason welding cable is better is because it has more strains than battery cable when both cables are the same gauge. Same reason you wouldn't use a single solid wire
X2 on the welding cable. 2ga, stock 93 mustang gear reduction starter. has worked fine since 99, daily driven. X2 on the strand count. it's easier to work with and less likely to have significant voltage drop under load. the welding wire insulation isn't as chemical resistant as automotive wire but as long as you don't let fuel or oil sit on it, it is just as good as anything else.
More strands does NOT make the wire more conductive, just more flexible. The conductivity is determined by the volume of copper not the number of strands. A solid copper conductor would be smaller than cable simply because there is no gaps between multiple conductors. Welding cable is slightly more bulky than normal cable but the jacket is softer and the extra (smaller) wires makes it flex easier and into tighter bends.
Sorry, I mis-stated that. What I meant was that a 2ga fine stranded wire will carry more current with less voltage drop that a coarser stranding of the same physical size due to the fact that there is a greater volume of the conductor in a given wire cross section.
so go get 2/0 which is 2 awg wire from a welding supplier shop? Anyone know how many feet I'll need roughly. Best mounting location? I would think center behind the backseat would be best but routing could make that a problem.
That's where mine is. the positive runs the rocker panel inside the channel that the wire loom on the other side goes, the negative goes through a hole and grommet in the trunk and follows the side of the tunnel to the starter bottom stud. 2/0 is actually 00, much larger than 2ga.
