McCanna, ND
We have 3.73s in two semis with double overs on tall 24.5s (11R). They are something like 1600 at 75mph. I wouldn't mind going to 3.55 on the one semi that only gets road miles as that trans worked out to 15-1550rpm at 55-65-75 in the last 3 gears with that trans.
I think you would be about 5% slower at the same rpms since your tires would be comparable to low pro 24.5s
How much speed will I gain with a “double over” transmission?
