Setup ?

[RACR_73s]

I am having trouble getting correct %'s on 05 grt
Left 53.5...should be 52.5
Rear 56.4...should be 55
Bite is 149#
Battery is on left side next to cell and can be moved to the right side but my ? is what does having too much left do to the car? What about too much rear?
Weight is on right side in middle under deck 100#

Rear % How big a fuel cell and how much fuel?..

Make sure jbar is the correct length and position and the wheel offsets are correct, the position of the rearend left to right can have a big effect on left side weight, might want to also check wheel base, if your a bit short you will have more rear. Just a couple ideas?

30 gal with 20 in it like GRT says. Normal feature is 15 laps in my limited division and if I ran super it probably wouldnt be more that 30. ~Thanks~

Panhard is 19 1/4 like GRT states, not sure I have the angle correct as both my mounts are adjustable and dont have holes as they state for a starting points. Have not checked wheel base as of yet, but is set to GRT lengths as to being square in the car...have not dropped the RR back a 1/4-3/8 like GRT says as of yet...undecided if I was going to do it as I like a tighter car and do not like the tail end hanging out...also dont like alot of stagger for the same reason. ~Thanks~

Too much LS% you will loose side bite on a car not knowing a GRT or weather your numbers is with or with out driver for me 53.5 with driver should be OK. And a heavy R% can be good on corner exit for drive but will hurt on corner entry making the car loose 56.4 is alittle much i think i would try moving your battery foward and right. We actually ran are's just behing the motor plate on the right side of the car and this was with a all cast iron motor and still had 54 LS and 54.5 R.

When the track goes slick, move your ballast up higher on the frame and that will help the car roll over and will help with side bite...We have an old underslung GRT and went with a 16 gallon cell mounted high in the frame, close to the deck and moveable.

Try scaling car with 15 gals of fuel. 20 gals is just a starting point. In a 15 lap feature, you will only use 2-3 gals.

If that makes car too light, add weight to fifth coil upper bar. That will change % very little.

Thanks to everyone for the advice. Sorry I should have been more specific...the car must weight 2400#(@ 2440# right now) and numbers are with diver(240#). Going to move battery to the right and take 5 gal out of cell and see where I end up.

You just need a smaller driver....LOL

At least, you dont have to add alot of lead like most of us!

With where you run I don't think you'll be out of line with that. too much left makes it "harder" for weight to transfer to the right going through the corner. the more rear you have, the more the car wants to go straight (or in whatever direction the rear axle is pointing). The more you push down on a solid axle, the more traction it gets, allowing the rear tires to slip less (until they break loose).

what's your cross at?

53.5 is on the low side for left percent with driver. GRT states 52.5 WITHOUT driver.

I think you should just lose some rear percent.

I have an older Warrior that had a huge 32 gallon cell in it, and it was mounted low in the car. I have down sized to a 16 gallon and have it mounted as high as possible. It made a big difference in the car. As far as making the cell movable, I can't move mine up or down, just not enough room. I didn't make mine movable left to right. I got it centered between the wheels so Bite doesn't change as fuel burns off.

It really depends on what you are trying to get the car to do. And if you are in a "Limited" class, I assume that means a motor with alot of restrictions; maybe even running against Crates? Lower HP motors tend to need less Rear% than a car with 600-700 hp. Something to think about.

call Joe and tell him exactly what your running... your left is pretty close. Rear is heavy.... Especially if were not talking about an open car, and at 2400 pounds i doesnt sound like we are.

Last time I talked to Joe @ GRT(couple months ago) he said that the %'s were with driver weight in the car. 2 yrs ago when I ran a GRT for someone else we did the setup without the weight in car. I am going to call in the next couple days for final setup help/questions and will ask again. ~Thanks~
