Why would you want to mount the fuel cell on the right side instead of the left side or middle? Thanks Eddie

the reasoning i have heard is as you burn off fuel you add left side weight terminator does that on his cars

Thanks 17j so the right side would be the most favorable. Havent got that far with the new car yet but im thinking that that might be the way to go. Eddie

personaly i think the left as far as you can get it is still the way to go i only burn about 20# of fuel in my main so i don't see much advantage unless you run long races that burn up alot of fuel

Actually, the left side weight is not changing, the right side weight is decreasing, thus increasing your left side percentage. IMHO it is better to mount it in the middle so your weight percentage/handling doesn't change at all as the race progresses.

But, the % changes from front to back no matter where you place the cell.

your right 01 what i ment by adding weight was %'s i can't add ballast or use weight jacks so the only way to get a decent cross % was to mount mine to the left

actually myself included maybe running to large of a cell most feature races the most u may burn is 6 or 7 gals i am considering going to a 12 where i have a 22 now and able to put that 60lbs where it wont be floating !!!!

if its on the left when it burns off it will increse cross wieght

Steve Smith's theory is to run the fuel cell on the right side, so as the fuel load is reduced it will increase cross weight thereby tightnening the car up. This should work together with the track, as it dries out you generally need to increase your crossweight.

Having said all that I run my cell on the left side to keep my left side percent around 52%. Next car I build I would like to move weight around in order to be able to run the cell on the right and keep left side around 52%.

if the fuel cell is on the right side an it burns off fuel it will decrease crosswieght not increase

If it burns fuel off the right it starts coming closer to the left side weight ,thus increasing crossweight.Seeing that when you do crossweight it rf +Lr divided into total weight.Lower the overall and it makes the cross go up!!

put a car on a set of scales and add a piece of lead to the left rear or even just lean of the left rear quarter panel, it will decrease cross wieght, it will add left rear bite but it will DECREASE cross, i guarantee it, i scale my car almost every week, it was a suprise to me but it is true

ADDING WT SHOULD NOT EFFECT CROSS WT.

ONLY ADJUSTING SPRINGS, TIRE SIZE ETC.

ADDING WT ADJUSTS LEFT TO RIGHT AND FRONT TO REAR.

BUT ANY WT YOU ADD ON ONE CORNER WILL ALSO GO TO THE OTHER CORNER NEAREST ALSO.

Gotta jump on in here.You may see crossweight go up when adding weight to the right side of your chassis IF you aren't running a close split in the rear springs. If the rear of your car is (just for conversation sake) weighing in at 1800 lbs and both rear springs are equal in preloaded length and in rate, you will see the weight becoming greater on the right side when you add it to the right. But in a stock car which has a greater spring on the left rear and right front, MOST of the time you can add weight to the right side and you will see the right rear spring absorb the weight and the left rear sustain it--thus adding crossweight. I put my cells in the center and up more than most, hoping for as little change in chassis dynamics as possible.
Oh and Oppendike-The reason I never replied was that I thought you had misread my post. Getting in excess of 54% left side weight is asking the chassis to do too much work with the inside rubber--UNLESS you are on a highly banked bad fast tacky track.
