Thanks FordTech58,
I actually did launch the bike at 9 psi at the track, but held back on the 60'. It was a 1.6 but then I pinned the throttle in second and she stood straight up and had to cut the throttle and stayed in second at a higher RPM and she came straight up again and had to cut the throttle once more. I then shifted into third and pinned the throttle again and the tire basically floated to the finish. I had a horrible ET 9.25 BUT the trap speed was 165 mph so she was pulling like a rocket at the end. I did not try to launch it at 9psi again. My other runs were in low boost 4psi and I was in the 1.4's for my 60'.
Overall, I was very disappointed.but realized with stock gearing and with only a 6 inch over swingarm, that was just not enough. I ordered a Chromoly 12" over with under-bracing and a 44 tooth rear sprocket. I'm going to take it back to Johnny Turbo and have him add a progressive controller and maybe up the boost to 12psi at the very end of the track.
