Went to the track
Wanted to do some baselines before the Procharger
12.64 @ 117 mph 2.15 60 foot. M7, AFE, Diablo, street tires. put it in track mode and nothing else, left the line as I would fro a stop light.
A few things I want to ask for some help with:
1 - fastest run was the first run of the night, but 60 foot sucked. I tried launch control (2.9 60 foot), tried no nannies (2.1 60 foot), and then tried no nannies leaving at 3000 and spun for another 2.2 60 foot
How are people launching on street tires, my launch control sucks - is there something wrong with it?
2 - I missed shifts on 2 out of 4 runs - bad - the mgw shifter is coming thank god, but wow, I hit 5th trying to get into 3rd twice. Is anyone else seeing the same thing with the stock shifter - maybe I'm not being gentle enough...?
Interestingly enough, the car had plenty of bite at the track when I was lined up properly - My car with a 1.8 60 foot would easily be a 12 flat car I think, at least a 12.2....... how are guys leaving the line on street tires and cutting the 1.7 and 1.8's I see on the fast list?
Video here - go to 1:16 to see the start of the race

Turn off all the nannies, well prepped track (sounds like yours was hit or miss), and don't let off the gas when you shift (and shift faster).

For shifting, I read somewhere that for the shift to 2nd, have palm facing driver-peddles. Then for 3rd and 4th rotate palm to top, slightly towards the right side of console. This will help you not miss shifts.
I have found it does help, a lot. I saw a chart for this, but can't find it now.

I think low 1.9s are likely the best you will be able to muster with street tires. I prefer the challenge of street tires in this regard. The key is finding the balance between clutch slippage without frying it and spinning the tires needlessly.
I'd try more rpms with clutch engagement occurring in the first 4-8 feet. Its a lot of trial and error.

Anyone in St Louis want to head out to gateway in 2 weeks for wide open Wednesday?

The new A6 C7 seems to be more consistent and have much better 60' times on a bone stock car
In your case as it sounds like drag racing may be new to you---You must launch the car by revving it up to 3000 and pop the clutch Keep the traction control ON Without tons of seat time on a manual trans with the TC off you are fighting an uphill battle
A tune will greatly benefit your ET's and 60' times
A stock tune will NOT allow the T-Body to go to wide open until the engine reaches 3200 RPM's So by design it is slow off the line--a tune fixes this
Also by tweaking the TC TQ number up higher you can get a great launch ( just on the edge of spinning) The STOCK TQ max values are very low below 3600 RPM Again a tune will correct this----May take some trial and error to find which TQ value works best with the TC on-- Again with the TC OFF you will roast the tires and have to feather the throttle on the start which is in consistent and not fast
PS: I could NOT get the so called launch control to work either as they explain it

what did you run? I missed your name on the fast list.

I would get solid fundamental baseline numbers off a STOCK car. No tunes, no tricks, no slicks....just a baseline car and get the mechanics of launching down. Once your times peak (low times that is) AND you want to go faster start the mods. But do ONE mod at a time.

Unless I had some sticky tires on!
My fastest times on street tires were with a off the stop sign start.
With about 1200 rpm and feathering the gas not hitting full pedal till 3rd gear. This was at track with poor or no prep.
I was in the top ten on the early list (C-6) with 11.98 2.04 60ft 120

Drop the rear tire pressure to around 24PSI. Don't do a huge burn out, but do spin them a few rotations out of the H2O box to clean them off. Once staged, bring RPM's up to about 2800 (this will vary depending on track conditions). When light goes green hold throttle and ease off the clutch bringing it up semi-quickly but smoothly. You'll get a little spinage, but once you feel them start to grab roll into the throttle.
It definitely takes some practice. Good luck.
