Relocating battery to boot.

nice 1 guys

so why the need for a distribution block?

 

[Indy]

You can connect other electrical stuff just incase you decide to add more stuff...

Here's one I have installed and works fine:

As for the cable just incase anyone needs to get some here's a good deal:

Erm ... to distribute power that used to be attached to the battery???

 

[PhilW]

One power goes to the fuse pack and one goes to the starter motor.

i finished mine the other day... its strange how you do seem to notice a difference in handling. its worth doing if you ask me for that reason alone, i had other reasons to move so it was a bonus for me.

pics in here if you want to see. thanks for the helpful thread Rob

As we see, the relocation of battery and other items such as windshield washer bottle is recommended for better weight distribution

Which is the weight distribution on a stock Leon Cupra/FR with 20VT engine and FWD? Couldn't find data on the net.

The official data in the registration papers claim a load on the front axle of 955kg and 910kg on the rear axle, assuming a loaded vehicle with full fuel tank. However, this would lead to a front/rear weight distribution of ~ 51/49 percent, which is very close to the ideal and renders expensive modifications pointless.

If someone has data available, please post them here (for FWD Leon Cupra/FR in the first place, but for 4WD models would be also useful)

Thank you,

These mods are neither expensive or pointless, by moving the weight of the battery and water tank off the front axle, this improves steering response and turn in, the weight in the boot gives improved rear end stability. I couldn't care less what anything says on bits of paper.

Very unlikely a Leon has near perfect weight distribution.

I find it myself rather weird to have that kind of weight distribution in a modern hatchback, the Mk 2 Cupra and it's brother the Mk 5 GTI are quoted to have 63/37 percent or 62/38 at best, which is a very ugly thing

On the other side, a Mk2 Cupra owner quotes a pretty different figure:

pt. 14.2: Distribution of the mass between the axles:
Axle 1: 1019 - 1047 kg
Axle 2: 898 - 926 kg

pt. 14.3: Technically permissable mass on each axle:
Axle 1: 1047 kg
Axle 2: 926 kg

Now this would lead to a 53/47 distribution which is much closer to normality as we understand it, however the total weight of the car seems to be again for a full-loaded vehicle with a full tank, otherwise how on Earth would a Cupra weigh over 1900kg?...

[probee]

I think those figures are just for max permissble weight per axle and not weight distribution

 

[Nautilus]

Will a lightweight battery such as Odyssey PC680 (less than 7kg compared to 18-20kg for the original) yield similar results? I don't feel comfortable tearing up my floor trim for wiring to the boot

well clever boy! i actually knew that but just thought it could of been joined in a different way

 

[neil]

all ready to put the battery in the boot of my leon but unsure where to run the battery cable from the engine bay into the car , can some-one point me in the right direction please.
neil.

 

[jack-cuprar]

im with neil on this one

 

[RobDon]

I ran mine down the passenger side on the inside of the car under the lower trim panels (sill and rear arch plastic trim panels).

Hi mates,

I want to put my battery in the boot to. I found all the information, that I need. The only fact that I still don't know is, what kind of "inline" fuses did you use? 150 ampere?

Cheers,

Tobi

 

[Indy]

Its not a must to use an inline fuse.

P.S Make sure the cable that you use is nice and thick preferably a welding cable.

 

[DannyC87]

IIRC mine is 250amp

 

[tobi20v]

The cable that I used is 35mm² I think that should be thick enough.

Do you think 150 amp fuse is to weak?

Cheers

I think the cranking power required for the starter motor may blow a 150 ampere fuse.. only one way to find out tho!!
