This is the rpm log from my old convertor on my 9.66 pass. There is very little rpm drop on the shifts and the car was running through traps with too many rpm for my combo. This convertor spooled instantly which was a good thing. I was just getting more slippage than I wanted.
Fast forward to last Sunday. New convertor I am trying out from PTC. Notice the RPM drop on the shifts and the RPM at the end of the run. Looks much better. I think the slippage is a lot less. (OBTW the jump in first is from a slippery track..) Both convertors spool up identically.
