Just checked the weather forecast. Looks good http://www.camaroz28.com/forums/images/smilies/smile.gif
Tires: Unfortunately, I only have stock sized Nitto DR's.
Gear: 3.55's
Tranny: Viper internal'd T-56
Driveshaft: stock aluminum
Clutch: SPEC stage 4
Flywheel: SPEC Billet steel(heavier than a stocker so more inertia)
About the only thing I can do to help traction(I've done this back when the car was a TH350) is disconnect the front sway bar. I also should swap out the stock LCA's and put the BMR LCA'S back in. The roads here suck and are absolutely teeth rattling when you drive with the poly bushed LCA.
Other than changing plugs, I'll probably stop there as far as prep.
Well... Only got to make the one pass tonight. The Clutch got kind of stuck after the burnout when I was going to do the second pass. It was weird. THe pedal felt fine but the clutch wouldn't disengage so I could put it in gear. The burnout went fine and the car hopped right up to the staging lights. I clutched it so I could tickle the car into the staging beams but it was acting as if I'd never pressed the clutch pedal. I had to be pushed back off the track. Once there, with the motor off, I put it in reverse and cranked it. It bumped a couple of times, then caught and I backed it into the pits. After that, the clutch made a few 'inappropriate' sounds like squeals but returned to functional status. WTH? Anyway, on the one pass...
I'd ran out of time and didn't get to unbolt the front sway bar. I also didn't get to swap out the stock LCA for my BMR. This caused the 245x50x16 Nitto DR's to do some wheel hopping. I *did* the short 1st to 2nd shift and 2nd gear felt flat wonderful, then I shifted to 3rd and 4th normally but the acceleration felt a bit flat so I let off before the end of the track.
Result:
Reaction: 0.135
60 foot: 2.017
330 ft mark: 5.417
660: 7.941
MPH1: 108.52
1000 ft. Mark: 10.041
1320 ft mark: 11.876
MPH2: 119.86
The time slip is so grainy it's hard to see and I'll post it in a minute. The Cobra beside me thought he was going to hand me my head. I think once I got into 2nd gear, he had a rethink moment. Looks like he let off and coasted...
Here's the pass. Please forgive my wife's shaky camera work (Think Blair Witch), lol..

There's no need to watch after the 13 second point. http://www.camaroz28.com/forums/images/smilies/smile.gif
You'll notice some 'stuff' coming out of the exhaust in 3rd and 4th. I don't know if it was running lean (max PSI for the run was 14.4) or rich. I have a wide band in the pod but I didn't look at it. The car wiggled a bit in second and I was focusing on that. Like I mentioned, acceleration felt a bit flat in 3rd and 4th. I'll have a look at the plugs and take a 3rd gear pull to watch the wide band and see if I can determine what's going on.
It sure felt great to be racing on the track again after a 5 year absence.
Timeslip:(very grainy. Sorry!)
