Shamless Plug!! Stupid Title to make people click it, then onto a Shameless plug.
thats just his avatar thingy mate
As for the question... i havnt seen anyone relocaten the battery in the boot on an a3/s3.
I did it in my old nova track car and my dad has his relocated in his 172 turbo, pretty simple thing to do really
I just didn't want to do it and it throw up a code or anything like that
i cant see how it would throw up a code. as long as you do it properly and use proper gauged cable and re-earth it in a good place then it should be fine.
I know it won't throw a code i wanted to do it right
There's was a chap in a stripped out 1.8T 5dr on our stand @GTI Inters, it was silver with black LM reps I think? He had the battery in the spare wheel well. Don't know his username though....
A few of the cupra boys have done it but not seen any a3/s3 guys do it.
Would be nice to do, the s3 engine bay is a right bitch to work on, its tighter than a nun's chuff, haha.
The reason i want to do it is to make a ram air for the air filer from the grill
I relocated the battery in the Polo that was at Bill's for a BT conversion...
Where did you get the cable from?
Bill ordered it in mate... no idea other than that...
The pictured A3 is indeed mine. Moving the battery to the boot is fairly straight forward (on a stripped out car anyway!)
I wanted better weight distribution, and also needed the space for an air filter. Any more questions, please feel free to ask me
Just want to know spec'c of the cables and pics if that ok?
Used 50mm welding cable on the Polo...
Thats easy and cheap
I just used some cable I had from an old ICE install. I *think* its 4 gauge. With a "fully laden" car, you might want something a bit more hefty though. Although saying that, I never seem to have any troubles with mine, it doesn't get warm or anything, but then again, there isn't really a lot in mine to power!
have you thought of relocating the washer bottle as well? Too a smaller bottle and chuck it in the boot too?
No why would i want to do that?
The reason for the battery in the boost is to clear a path way for some ducting from the grill, though where the battery used to live to the side of the air box
Well as you said you need ducting where your battery is then moving your water bottle isnt needed, just thought you was tidying it up And putting it on the rear left for weight distribution.

I'm doing it for better air flow to the filter not weight distribution
Its a S3 its a heavy car to start with
Plan is in action no as i've just got another airbox to replace my holly one and the rest of the stuff needed
All will be clear when i post pictures
I done this in my a3 i used, 2 X 4 gauge wires to the back for the power then re-earthed it again in the boot. I would also fuse it as well to be safe, i was told to fuse it in the front and the back but ended up just putting a fuse in the front.
if you do fuse it, which i would then its best practice to do it as close to the battery as you can otherwise the cable between the battery and the fuse at the front is affectively unfused and in the event of a fault could cause some major fireworks and even set the car on fire!!
in my mk2 20vt i fitted a 200 amp megafuse from vehiclewiringproducts
You could always just turn your battery 90 degrees n take closer to the middle of the car. Not sure If I've got a pic but I removed the old battery box n made a new tray out of aluminium. Not got as much space as if you moved it to the boot but it's a lot easier n takes about an hour.
or just buy one of those small batteries
Here's what I did: (ignore the horrible 3 pipes above the battery, temporary job)
i'm trying to keep the battery cover
I did concider this when i looked at fitting a new filter an putting a round hole in the side of the air box with ducting straight to the grill.
I was going to make some kind of bracket too to keep the cover where it is but then i toyed with the idea of an induction kit with just the ducting squezed in place of the old cold air feed
The battery cover sits over the top, this picture was taken before I made the bracket.
Lemon...you wana borrow my degreaser mate
LOL! Isn't the idea of moving the battery to the boot is to reduce weight up front? Lose the engine covers!!!
Yeah If you want to do it for me
tell you what, you degrease and i'l regrease sweetheart
I thought 4 AWG cable wasn't chunky enough?? After lots of conversations with motor factors and a specialist cable co. I concluded that 0 AWG was the right spec for my Ibiza which had its battery in the boot. You may well 'get away' with something thinner but I didn't want my car to catch fire.
Anyway, put a two post cable joiner where the battery used to be in the front (handy for jump starting!) and a length of welder cable of a similar gauge between the joiner and the starter motor:
And attached the battery to the boot floor with a couple of ratchet straps:
Not exactly the neatest way of doing it but it was only a trackday toy.
