Well! We hit TnT this past Friday night: 12.69 @ 50+ mph!!! We pulled the weight bar out of the truck (that we've been hoping to need at some point!), and threw 25 #'s on it. The general ratio for a 12.90 Jr is 10 #'s = .10 et.
Got another run in, 12.79 at 50+ mph! The 25 pounds slowed it about a tenth, primarily in the 60 foot. We are going to leave it alone, as we feel the 64 degree temp with 72% RH will change for Sunday - which is supposed to be in the low 90's. We think the weather will slow us down to the 12.90+ range. This is a huge relief, Benjamin is all smiles - that's what its all about! Fast forward to Sunday morning: Right out of the box at 9:30am our first run was a 12.909 at 49.9mph! Benjamin had a nice reaction time of .039. Temp was 75F, 45%RH, we left at 3400 rpm. This was a picture perfect run, I'm not sure you can tune <.009> out of a 12.90 combo. Second run was at 11:15am, and we slowed a bit to 13.166 at 49.5mph, so we took off the 25#'s. First round at 1:02pm we dialed a 12.90 and it really picked up going a 12.64 at 51.2mph - not sure why, but it might like the heat as it was ~ 87F and ~50%RH. Also, the starting line was not nearly as tacky (that means less resistance, and actually will speed up the car). We lost the round, but it was a good day, it felt great to run a spot on 12.909. Looking forward to the next time out. I guess we'll put a fork in that old engine!
