That 11.49 was an unrealistic goal for now I guess. The car ran strong and consistently, but I need to hit an 11.5 before I can worry about 11.4s. It was way hot when TNT started, so I was down 1mph on the traps, but I was still running well. It took 4-5 runs to kinda figure out the DRs, since I started at 35psi and ended at 22-24psi. From run 4 on, every 60' was from 1.63-1.69, and all the runs were 11.62-11.71. I am a little confused on why my better 60's didn't give much better ETs, but there was a pretty strong headwind as the day went on. As it got cooler, we got the headwind, so it didn't help much in terms of conditions - my traps stayed very consistent within 1mph range. Here are my times once I got the DRs working well:
11.712 @ 118.86 - 1.685 60' (all my left lane traps seem 2mph higher than actual)
11.696 @ 112.40 - 1.671 60' (all my right lane traps are ~6mph slower than the left for me, or maybe I'm half Puerto Rican?)
11.677 @ 118.54 - 1.687 60'
11.647 @ 119.18 - 1.659 60'
11.639 @ 113.67 - 1.693 60' (hmm, worst 60' but very good ET - trap is my highest in the right lane by over 1mph to date)
11.633 @ 119.40 - 1.637 60' (wtf, great 60' and high trap but barely better ET than the 1.69 60')
11.627 @ 118.60 - 1.654 60' (worse 60' and lower trap but best ET - hard to figure out)
I had the DRs at 22-24psi and was launching at 7000rpm on the 2-step - it was nasty, but the ETs didn't seem to mimic the 60's. My 11.64 and 11.69 on Sat with street tires were both 1.68 60'. Maybe the conditions weren't quite as good, so my 60's were making up for that difference but not enough to drop down to the 11.5s. I am not sure if I should drop the 2-step down to 6500-6800 and raise the tire pressure some so I keep the drag to a minimum up top. I am not sure if I was spinning or what - I couldn't really feel the DRs as well as my streeties.
I had 3 goals with the 245/45-17 Nitto 555Rs:
- Cut much lower 60's - in the 1.5 range = Failure so far, but did get down to 1.63. Not really sure what to do to get 1.5s. Maybe my shifting before the 60' box makes this unrealistic and not even that big of a deal?
- Hit the same traps with lower rpm due to 245/45 tire size = Success! I was trapping the same...or maybe half a MPH lower on average, but my rpms were just above 7k rpm instead of upper 7000s. I think it made a 300-400rpm difference, although I'm sure it could be calculated easily by someone who knows what they're doing.
- Cut consistent 60's that don't jump from 1.71 to 1.88 as the night goes on and the temps drop = Success! I hit one of my 11.63s at 8:45pm when it had cooled off, a storm front had rolled in, and the wind was blowing straight back. All 1.6s all night.
