I hope to get a response back to your replies in the net day or two, but I did experiment with different tire pressures a bit last year, I can go through my old posts and logbook and see what some of the best 60 foots were and then look and see what my tire pressure was on that run. Will get back to you guys on all that.
Just wanted to post a few of the videos that Joey D took from that day, gives a better view of the launch and you can hear the tire spin/shutter in some of the videos.
