Max Amps Pulled From Battery / Cable Gauge Required To Relocate Battery To Boot

I searched for a DIY guide on relocating the battery to the boot, and surprisingly couldn't find anything!

Can anyone advise on the minimum cable gauge required to relocate the battery to the boot? I have a heap of 8AWG cable (61Amp capable) which I realise is probably not going to be sufficient, but I am just wondering if I run 2 of the lines if it will be enough?

Cheers :cheers:

depending on the quality of the cable i recommend 2awg as a minimum preferably larger,

i measure a starter on a v6 commodore 160amps on cranking. which has lower compression so i assume less work would be needed to crank.

Cheer's for the responses :no: Looks like even 2 x my 8AWG wire is not going to cut it!!!

I think I will leave the battery relocation for another time.

2ga is more than plenty, it is also the same as the -ve line from a mig welder. Hit up BOC gas and just buy some welding cables, works out cheaper than 2ga audio cable :)

My Gtr had the battery relocated to boot, used 2gauge cable, never have a problem with voltage drop or any other electrical problems (apparently these cars are voltage sensitive)

6 Cyl Starter motors usually draw between 200-400 amps. No amplifier wire is going to cut it. You need minimum 2 gauge battery/starter cable. It's about $10/m at repco from memory

welding cable works out a tad cheaper if you have a trade account :)

Also don't forget your starter motor will draw more current in winter and also when the battery is lower in voltage. You need to account for these factors so you don't catch things on fire. Safety first :)

I used 0 gauge audio cable. And I ran both earth and positive. I didn't want to earth though the body. U can't go wrong with over earthing.

Cost alil bit, but I hate wiring probs so I just over killed it so there won't b issues.

What are people using for distribution blocks once they have relocated the battery? Having a bit of a look at options for such things at the moment.

stereo components really.. you just need a good ANL fuse & holder that that's it.. don't waste your time with anything else :)

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
