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.
Does that calculator take into account tire growth and if its a radial or not?
