I was really amazed how much learning to launch the car picked up time.I thought for sure I was never going to get better than a 2.1 60' on street tires. I was wrong, I went from running 8.80s to running a best of 8.58 tonight in the 1/8 mile. It just took playing with the air pressure, alot of RPM and slipping the hell out of the clutch. I don't know my 60' on the last run (the 8.58) because it was blank for some reason on my slip, but the previous run of 8.64 I had a 2.0 60' so I am assuming the the 8.58 run was sub 2.0 as that would be the only thing that would really change. Just wanted to give guys with IRS cars some hope, it takes alot of practice but it is well worth it and I am confident I can do it again now any time. Oh btw this was with me bouncing off the rev limiter right before the finish line.
