Left Side %

[rubbinsracin]

will to much left side % keep the car from getting up on the bars?

[joedoozer]

Yes......but

If the weight was mounted high in the chassis it would still help the car "tip" over, instead of the weight being below the axle for example.

ic. well im pretty big guy. about 285lbs. the guy who had the car before us was about 175 lbs and he said the car worked best for him at about 54% Left % and with me in the car that gets up closer to 58%. should we be down closer to the to 53-54% with me in the car?

also, we have only one piece of lead on the back side of the car that is right behind the LR tire on the frame rail. we are thinking about taking that off and see what that does to the car. other lead is mounted high over the drive shaft.

always do your scaling and adjustment with you in the car. If it needs to be around 54%, move ballast until you get close to that. If you don't have ballast to move, look at things like relocating fuel cell, battery, etc to the right.

58% is pretty high regardless of the chassis. Unless you are getting a ton of side bite (which is hard to imagine with that much left), you won't be getting up on the bars very easily with that much weight on the left side of the car.
Assuming everything else is right with your setup (springs, shocks, bar angles, j-bar, etc.), the high left is likely your problem.
How does it actually handle?

I am almost the same weight as you. Move your battery on the right upper frame rail and also put weight/lead over there too. Us fat guys put too much low left in the cars so I found high right makes it work great. I like 54.3 to 54.8 left side percentage and about the same rear. All cars are different but my experiance is using my numbers will get you (not a nice word)(not a nice word)(not a nice word)(not a nice word) close. Your car might be heavy but it will drive better.

we have all the setup stuff exactly as it comes from Shaw. only difference is we are running a straight 3 comp/reb on the 5th coil instead of a 7-3

surprisingly i felt like the car handled pretty good, just didnt get up on the bars at all. im new to a 4 bar car(came from an old bomber class) so i give up some of speed because im still getting used to the way the car feels. i finished just 11th in my first feature. but the difference between the top 6 or 7 cars and the rest of us is they all run the 602 crate and they only have to weigh 2150 and we have to weigh 2475 with our 11-1 GN motor. so unless we really get this car handling, its going to be hard to beat any of them anyways.

[rubbinsracin]

our batter is already mounted to the right side of the car. so we will try moving some lead and the fuel cell to the right and see if that helps the percentages. were going to try and get closer to the 54% with me in the car instead of 58% we are at.

[MasterSbilt_Racer]

Move the engine right as well.

[rubbinsracin]

its as far right as it can be without relocating the fuel pump which we are not allowed to do as it must be in stock location.

[joedoozer]

If you don't run a lot of long races you can get by with a smaller fuel cell as well. Then you can slide it over to the right. I will be doing that in the off season. I have a big tear drop style cell, that I can't move. I don't know how much it holds, I can't afford to fill it. I know its the size of a gas grill under there though haha.

[rubbinsracin]

i have a 22 gal cell that i can slide about 8-10 inches from right to left. but yes we will probably be going to a 12 gal cell next year because the longest feature we run is 40 laps and the end of year special. and as long as we top it off for the beginning of the feature(if we make the feature) we should be fine. we should be able to move a 12 gal cell 18" or so each way if we get the skinny cell.

[4bangerhotrod]

if you cant get the ls weight down to 54% you might want to try to hang what weight you have mounted on the car weight up high on the chassis to help with roll over

[lovinlatemodels]

I would try to get the fuel cell about 2" to the left side of center or even centered that way there is very little effect of fuel burn off. To me never have the cell to the right of center you don't want the car gaining LS% during a race. I am also a 270 lb driver and what i got is my battery mounted high on the right side just behind the tranny. Now i also run 70 lbs over the rear between the shock mounts favoring the right side slightly. I still run 55% but with the weight that high in the car over the center of the rear it alows the car to move around. Also becareful not to get to much over the RR only as this could allow that part of the car get pinned down with to much weight hanging there. JMO

X2 on lovinlate's post, those are good points. the fuel cell moving was just brought up in a suspension class i went to. if you don't burn much fuel, then that's an option.
