you could always try disconnecting your front swaybar (track only) getting a set of drag shocks and springs, getting skinnys up front and playing with your rpms at the staging lanes...it doesnt seem like you have done too much with suspension...just my point of view...you can have the power to be quick, but its usless if you cant get it to hook

Cleaned up your original post and changed the title to help with feedback. Add your track timeslip to the original post as well and hopefully you'll get some feedback!

You should be much faster! My bolt on a4 Lt1 was running similar times. You should be in the mid 12's at least although the 60 ft times are not great. I would check the tune. You should be able to get much more out of that set up. Where are you shifting at? The cc306 loves rpm.

If you're still running the PCM4Less tune, that's problem #1. My LT1 bogged like crazy with that tune. What RPM were you launching at? If you switch to ET Streets and dump it at 5K I bet you'll see some good 12's. If you have LT1 edit, take it up to RPM in Lewisville and have them fix it for you. If you don't look at it on the dyno, you won't know when to shift.
Just a comparison, I used to run 8.40's in shitty Abilene air with just an LT4 kit, MadZ28 tune and ET streets.

the car is like 589000 lbs not inc driver.... driver could be a large man no offence.. lol
mph matches et... i would get a tire and work on the tune.. you can always knock .5 sec off a new eng car by dicking with it long enough...
