On the converter, I believe it's the supercharger kicking in that hard to hold back. A tip is once you light the first bulb, then get on the brake hard and rev it up to load the converter as much as possible and it pushes you into the second beam, then hold the brake as hard as you can and be ready to let it go on the 3 yellow as they light up. You should get a great launch and 60' time which will lower your overall time. Mph is always lower on your fastest run. If not, then you are leaving a few hundredths on the launch. Be safe and have fun. Lot's of practice to have great 1/4 mile times.
