Battery Relocation Considerations For S13

Morning Gents and others...

I'm looking to relocate the batter to the boot in the S13 track warrior and I'm wondering what the ruling is on a battery in the boot when there is no partition between the boot and the cabin, as the rear of the car is stripped.

It's a standard Calcium hybrid battery, with vent holes in the little plugs where you can top up the distilled water if necessary.

In my head I think you have to have it fully sealed in the boot but with some ventilation to outside of the car, does this sound right and if so how have others done this.

Cheers

searched the CAMS manual but failed to find anything on the website version.

can a normal battery be mounted in the boot of a 32. It doesn't share the same space as the cabin so is that considered isolated from the cabin? reason I ask is that I have a batt box but it's massive and can't find a nice small one to fit neatly in the corner of the boot so wanted to know if I can just mount it in the corner without the box?

Sealed from the cabin is one thing but don't you have to vent a normal battery to the exterior of the boot space? Or is that only if there's no partition between the boot and cabin?

have a look at how R34 GTRs do it. they have a little vent tube that exits through a small hole (with rubber grommet) in the boot floor. with a battery like that you would probably not have to box it. places like battery world etc have those batteries. they are basically a normal battery that are sealed on top with just one vent for overflow or gas and it comes with the tube already attached. that's what I'd use. they are designed to be used in the boot space of cars (like R33 and R34 GTR etc).

ah ok. I was thinking I could get away with it as 33 and 34's have it basically sitting in the boot. Didn't know about the different kind of battery.

yeah 33s and 34s are sitting in the boot but they are sealed on top and have an external vent/drain pipe. it's just a little clear plastic pipe about 8mm diameter and I guess they've just covered the top of the battery with a plastic cover with just the single vent hole with pipe on it instead of little vents on each cap. they are easy to find and no more expensive than other batteries of similar size. not sure if you have battery world in melb but if you do go there and ask for an R34 GTR battery and you should get what you need.

cool. personally though I'd still buy one of the batteries with the vent tube on it. they are not really any more expensive than other batteries of similar quality and size and it's nice to have the knowledge that if it does need to vent it's not going to do so all over your wiring, or surge tank or whatever. :)

they look like this:

see the little picture of the race car on the battery? just above it is the point where the vent tube connects. most come with the tube too. any battery world shop will supply one.

edit:

found an even better pic. you can see clearly where the drain tube attached on this one.

Thanks mate. I will get one of them next time or maybe even a dry cell.

Seriously, juest get a dry cell. It depends on how many amp hours you think you want but it can save quite a few kgs.

This is just on Amazon. Proper Braille motorsport battery.

Braille Battery 11.5lb, 904 pulse cranking amps, 360cca, 15amp/hr 1yr warranty - Left Side Positive Terminal

Cost is $160 + freight.

You can get other larger capacity (amp hours) locally for not much more.

The one I got for the Silvia was from a local guy, $150, 780PCA, around 280CCA, weighed a kg or two less than what I had.

Perfect for a little 4 banger like mine. I reckon it'd start a small 6 easily enough too.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
