Ok so as the subject states has anyone done this? I've been flirting with the idea for awhile now about transfering the battery to the trunk area of my wagon. Reason being is that I eventualy wish to make a custom CAI for the wagon and the batter is just well in the way. Not to mention the small weight savings up front. I know I'll have to spend some money on the kit but well no harm in asking right? Oh its also a NA Wagon.

 

People have done it. I don't think it's necessary. Just get a smaller battery and put it long ways in the same spot, opens up a lot of room and saves a lot of work.

 

People have done it but CAI on an N/A won't give you the same results as if it was a Turbo. You can still do it, but for the small amount of power you will get, it 's too much work. As far as weight savings, you drive an 850 wagon. It's heavy enough from the getgo that a battery is nothing to displace.

 

I know I wont be getting gobs of power out of the CAI if anything I'm doing it in hopes of increasing my gas mileage. For me I get bored easily so lil tinkering here and there keeps me outa trouble lol.
Also does grounding in the 850 produce any positive effects? Some of us did it in our Rx-8's and noted better start ups and some minimal performance gains.

 

Ok well since you put it that way...Mod. away then!

 

When I get to it I'll be taking photo's and whatnot. Thinking of buying some gold reflective tape to put around the outside of the box I make to shield it from heat. If I get atleast 10% increase in gas milage (about 2mpg with what I get now on avg) I'll be a happy damn camper!

 

well ill tell ya what. i have the rear ripped apart in a wagon right now. and i have a spare standard size battery laying around also. let me see where it fits best.

ill let you know shortly here.

 

Sweeet. I noticed once there is a odd dip on the drivers side but its to small to fit any sort of battery in.

 

ok it looks like the best rear re-location spot for an 850 wagon would be on the driver side below the window. the only issue with this is that it will interfere with the cd changer if you have one installed there.

but the battery fits in perfectly and snug. sticks up about 4-6 inches (i didnt measure it, i can if you would like).

 

No need and thank you. I dont have the CD changer so it should be fine

Once I get a few things fixed on the car this should be a very interesting project needless to say. I was very shocked when I first took apart the airbox and found that it sucks air from a slit that is about a inch tall by 6 (or so) inches long and feeds it down into the box which sucks it up then over to the engine. To me its just very restrictive and again be a interesting project to keep me outa trouble.

 

Dont put it on the driver side... The whole point of moving the battery is to shift the weight balance to make it more even driver to passenger side. Moving the battery to the rear of the car is like moving the motor closer to the firewall ~10"! which is what you want for better handeling....
You can do it fairly cheap also...
Just go to the junk yard and find a 90's+ BMW 540. pull the battery cable. it should be perfect lenght.

If anything, get a lightweight racing battery.
