Ajustable torque arm I run 12.20s w/M6 I bog on my launch and I leave on the rev limiter.
I have a ajustable torque arm set @-3 should i set it to 0 in hopes to get throw the bog? What do the 11 sec. cars do????

I would try a 26inch tire, bump the limiter to 6400.
dont leave on the limiter, but just under it.
are you trying to keep it SI or what. A nice cam and you would be out...
FWIW, when I had only 4.11's, slicks, headers and a lid I went 12.20 @112 1.70 60'..
About the same as where youre at..... cheap heads, torqure ii cam some weight reduction and suspension 10.95 @ 125 1.42 60'... Just need more power probably.

Trying to go as fast as i can with SI hoping to be alot faster after the new tune and afr in the right spot. I will try to leave under thr rev limiter next time to the track. Puting my race tires on today and next wed going to the track!!!
Pinion angle has no effect on traction. For some reason this misinformation has spread throughout the forums. You can change your instant center by positioning the height at the front of the torque arm, allowing you to soften or strengthen the hit to the tires. This is only possible on custom applications or full length torque arms with torque arm relocation crossmembers that allow height adjustment. Pinion angle should be preloaded negative. The amount depends on your power level, the amount of flex in your suspension, and how hard you launch. -2 degrees is a good place to start for most but a car with a manual transmission leaving off the rev limiter can go up to -4 to -5 degrees for the track only. Try not to exceed -3 on the street.
