Left Side %

[rubbinsracin]

we burn about 8-10 gal of fuel during an entire night. we run a 8 lap heat and a 25 lap feature on most all nights. maybe 2 times a week will we run a B or have a feature that is 40 laps. seeing as the AV Fuel we use weighs at 6.75lbs/gal we burn off about 60-70lbs off during the average nights racing at the most. so should we move the cell so it is just about centered? or just a hair to the left?

were going to work on the car tonight. gotta pound out some sheet metal and and then we might go ahead and put it on the scales and play with it.

KEEP THE SUGGESTIONS COMING!

I would find center of car on scales then move the cell 2" left also if you can keep it mounted high to help the car roll.

[rubbinsracin]

we have it mounted as high as it goes. we are going to run it pretty much centered over the rear to get the fuel burn off to be as equal as possible. we got it down to around 54.6% left side with me in the car. and about 52% rear but we need to add 15 gal of fuel then we might need to add a little bit of lead in the center of the car to make it up to weight. we have to weigh 2475 and have no idea other than added weight right over the drive shaft as high as possible to get into allowed weight. because if i finish the heat and dont make weight we get parked for the night.

So how'd you do with the changes?

[rubbinsracin]

This is what we ended up going with.

Springs
LF 500 RF 375
LR 250 RR 200

Shocks
LF 5c5r RF 4c6r
LR 4c4r RR 4c4r

bars are all in shaw "stock" locations execpt the LR bar is 1 hole up on frame and on the bottom on the birdcage

jbar is just below centerline on pinion and second hole from top on frame. one hole above "stock" location.

all numbers with me in car

52.5 Left %
54.5 Rear %
cross was about 52% (if i remember correctly)
115lbs of LR bite

we are thinking about some different setup options for the LR still.

since i'm still a little inconsistent about being on and off the gas through the corner a guy that is successful that parked down the pit from us said to possibly just mount a gas traction shock in front of the LR. with about 125 psi in it. so when the car get up, it doesn't come crashing down when i get on and off the gas. seems like everyone is running a second shock on the LR but a few of us that are at the back of the pack.

should i just go ahead and mount that ahead of the LR without making any other changes? or should i dial back the wedge so it is where i want it with the gas shock on? i have heard both ways, but if i set my wedge at 115lbs or so and then bolt that shock on i will have way more than 115lbs if i understand correctly. or should i set the wedge with the traction shock on the car?

This might sound stupid but for me I make the throttle travel pretty darn long so it is harder to come completely off throttle. Also work on draggin the brake in combination with the throttle before going for other changes. JMHO

Scale the car with the traction shock on, set the bite(115#) or to what ever you want to start with. As it will add a lot of LR weight. Then take the shock loose from the bird cage and let it hang. After taking it loose, these are the numbers I write in my scale book. May be as low as 40# LR. This is the most consistent way I have found. With the LR front shock, nitrogen pressure, and how you settle the car will change the bite every time. Easier to just unhook it.
