Nice videos, Shaneirish, and congrats on the win! I didn't hear so much as a chirp in the first video. I heard a bit of wheelspin in the 2nd one but it might have been the other vehicle. I might be totally wrong about what I think I didn't hear, though! I am still a novice but the launch will certainly make or break the run. Unless wheel spin is the issue, I don't see how lowering tire pressures could help unless it actually results in slightly smaller diameter of tires and thus, simulating a bit lower gearing.
In looking over all of my time slips from the times I have been to the track, the times from 1/8 on through the quarter are nearly identical. However, there is more variation in the 60s and in the 1/8. A 60 over 2 is not going to yield a good 1/8 or a good 1/4. I can do 1.9s but I haven't cracked the code to get into the 1.7s like Rich and some others. Since I have barely any wheelspin, I am pretty sure I am not launching aggressively enough.
