I was there in my silver QC, there was a grey QC, a black SC, and a red SC. The grey QC is my Dr. and weight training partner. It was her first time to the track and her truck is stock.
This is my first time since installing a full new exhaust. Air temp. and humidty were pretty good. There was an 8mph headwind though.
I removed my back seat, folded my mirrors, ran with 45 psi front/24 rear, and launched at 1600 rpms on the 1st 3 runs.
My runs were:
1 -- 5:59 CST
r/t .599
60' 1.975
330' 5.462
1/8 8.351 @ 85.10 mph
1000' 10.874
1/4 13.010 @ 105.52 mph
2 -- 6:04 CST
r/t .529
60' 1.985
330' 5.500
1/8 8.402 @ 84.72 mph
1000' 10.935
1/4 13.073 @ 105.38 mph
I let my truck cool
3 -- 7:02 CST
r/t .006
60' 1.976
330' 5.434
1/8 8.307 @ 85.56 mph
1000' 10.817
1/4 12.938 @ 106.21 mph
I removed my spare tire and tailgate, and launched at 1800 rpms
4 -- 7:55 CST
r/t .001
60' 1.951
330' 5.384
1/8 8.235 @ 86.25 mph
1000' 10.724
1/4 12.830 @ 107.08 mph
This is my second trip to the track in this truck. I continue to be very pleased. Next trip I'll start the night with the back seat, tailgate, and spare tire removed. I'll also raise my front tire pressure to 48 and drop the rear to 22. I'll continue to launch at 1800 rpm but will put my foot into it faster. I took the advice of a recent posting and warmed my stock tires up 10 seconds or so and had no traction problem. I wasn't stomping it at the line though. Was instead using a fast constant push. One thing that was different tonight than the last time to the track is I was shifting into 4th before I crossed the finish. Would there be a gain by going with a slick at the track and getting it slightly taller to delay the 3-4 shift, or would doing so compromise low-end accelleration negating the time gain of 1 fewer shifts?
Thanks to everyone for the postings. I'm learning from you guys and having a blast.
