7XL gearing, ~45mph ?

Hmmm, yes, all very good points. I guess this just shows just how difficult calc'ing these things are. For what its worth, the truck is usually still accelerating as I'm holding the radar, but is topping out as its getting too close to radar. The hard part is finding a long enough runway to really see where it tops out, but its close.

The calc is very good tho, don't get me wrong, great job on it. Its very handy and seeing the gear ratios in one place is great. I guess its that one can't get too wrapped up in the exact top speeds as there are so many variables.
