I know this is flogging a dead horse but where should the battery be on the car,is it along the same line as fuelcell position.And with that said how high is too high.

why do you have a max or 45% rear is that a rule or something anyway never put your battery behoind your seat if you don't have to for a couple reasons
1 safty just ask my uncle who had his mounted like that and he rolled and was hanging upside down knocked out while his helmet filled up with battery acid.
2 i have never seen a stock car that couldn't use more rear weight and the further you can get that 50-75# past the rear axle the more you can benifit from it .
right now mine is mounted in the trunk wherethe spare well is on a metric but next year i'm going to move the cell from the left to the center and put the battery on the left to keep from losing cross% when the fuel burns off

youve got the nova from columbus right??

racer 17 if your dad or any of your friends are spilling battery acid they must not be very good friends. I would think the way you offer advice on here on everything you would do the same in person and tell them that a battery goes in a spill proof container.

my battery is mounted behind the seat on the floor in a marine battery box. one of my buddies had a battery behind the seat and something happened with his cables, sparks started flying everywhere, he thought he was on fire. Needless to say his battery in his new car is mounted in the trunk. as mine will be next year. also how many of you have heard of this. one guy mounted his battery in the trunk on the right side and filled his old battery box behind the seat with lead and left it behind the seat. he says its like adding weight dirtectly to the left rear tire i told him to eat more.

Putting lead in a box is a good thing. But if your car is already above minimum why add more to the car to drag around the track.
I would rather mess with springs and air pressure than to physically add more mass to the car to get my percentages right.

Our rules say battery must be under the hood. So we built a box where the factory heater box would be. It's still under the hood, but just barely.

Why would you put a source of ignition (BATTERY) next to a source of fuel (FUEL CELL)? Seems kinds foolish to me, I don't htink that would be very safe at all.

I have mine mounted in a tray over the rear axle so I can move it left or right if I want to change weight at the track.

redneck, I agree but Ive only seen one car with their battery not in the trunk out of hundreds of cookie cutter IMCA cars.

Monkey see monkey do I guess!

posted October 24, 2003 01:46 PM
Rules say in the trunk for us, so that what this monkey has to do!

thats why you put a fire wall where the rear seat shelf is seen plenty of roll overs with batteries in the trunk but never seen them catch fire. only ones i have seen was where the fuel pump broke off and caused a fire

we run ours behind the drivers seat on the other side of the rear fire wall. we run a full tub like on a late model so everything is covered with sheet metal all around. i've been over 3 different times in three different carsall with the same placement and never had a problem.

personal opinion, the battery goes over the right rear wheel to help losen the car up. height really doesnot matter
