I get the best 60' flashing the converter or stall to about 1,000 to take alittle shock out of the rearend.stock 10 bolt with 3.73

I usually set the fronts at 2 and the rears at 6.the car feels like it does not spin,just hooks and goes straight down the track.I am not going to change the tires right now I want to keep the snowflakes on to look like a real street car.what can I adjust or buy to help get the 60' down to about a 1.55'

 

call madman

 

whas ur raceweight?

 

I'd tell you, but I'm content with where you are in regards to the stock internal list

 

a4 or m6?

 

Cody, it says he has a 3600 stall

 

Try 1800 - 2200 on the stall, & the front shocks on 1...

 

Have you tried loading up on the convertor? Is the car squating on the launch?

 

LOL, sometimes I miss some of the little details.

 

raceweight is around 3,280.as far as squatting im not sure I usally go by myself or my gf goes I would have a video but most of the time the races are at night. hah time in sig was old setup,ive made quite a few changes,removed n2o,deleted the AIR,installed ft85mm airlid,zo6maf,tune,relocation brackets.
debating on torque arm or rearswaybar.

 

I would go with the torque arm if the car isn't twisting up on the launch. Next time you think about it, go to the back of the car and see how soft the rear suspension is. I keep mine fairly stiff. I want all energy spent to go foward, and not squat at all.

 

We have about the same set up but I haven't touched my suspension as of yet. My best 60' s are when I leave at 2300. I am using a 2 step and tried to run it up higher but got worse results
