But that is somewhat artificial. The definition of flash is the highest rpm seen before the car moves. The car moves sooner/easier with the 4:10 than with the 3.73. That earlier movement might be more beneficial that then increase in flash rpm. Did the car improve in the 60’? Always trying to understand more about the converter smile


No, 60ft dropped a 10th. Slower by 2 10ths, Mph dropped 4 - 6 mph while rpm remained roughly the same through the traps. Slip increased from 10 to 17 %. I have since fitted another converter but no track time as yet.

Sounds like the converter definitely not happy. I know people who have tried increasing slip % at the top to try and increase torque multiplication down track, but no real results yet. 10% seems a bit high. I’m at 4-5 % at the stripe. Which car?
