I mean, I am under no illusion I should be in the 140 mph range. But 130s should be in the picture.
I re did the numbers, its 22% slip, not 30%.
Still, not very good.
I just want my E.T.-MPH to match my weight and 60 foots and the finish line RPM.
I am easily out 60 footing much lighter 10 flat cars.
The converter seems to be the issue.
When I get the fresh PTC in I will know more. Maybe I will call Hughes and see what they have to say-or sell me on. If there is a better converter, I want it.

What is your Et/mph? Rear gear and tire size?
