Do these stop numbers sound right?

One thing that I believe was an issue is the tight converter. While running an all out 1/8 mile race and launching at 4200 the converter was flat and seemed lazy. We upped the launch to 4600 and 4800 and the date looked much much better as far as the curve. So I am thinking with the RPM of 4100 on the stop it may be slightly below where I need to be while on the stop. Maybe an increase to 4400 will be where I need to be.

Well when it comes off the stop and its completely open you will have your answer. It will hit the stall speed and you can see how long it hands there. If you have some sort of logging ability, playback tach, Biondo 450 or similar or grid. Its certainly a big part of making things happy and getting the most you can.
