I'm not sure where you are on this car... I what motor/batt/gearing you are going to run. Maybe I need to go back and read the thread for a refresher. :)
You said once that you had a 1512 2.5d in the car but then mention a 9L...
I crunched basic #'s on the 1512 and 5s lipo geared 6:1 and 3" tires.... note that this is just "back of the napkin" math and it's just meant to be a basis to go off of.
I think you can break 60mph depending on how stong the lipos are.
Not accounting for some losses (efficiency etc) the numbers say 61mph with the battery holding at 3.2V per cell. I think this is about right because I'm guessing the volts will actually be a little better than that, which may offset the "real world" losses. On paper, in theory,..... doesn't always translate to real world results.
At the very least I think this setup would do mid 50's (that's assuming 3.2v per cell and 10% loss from the "paper 3"#)
Paper #'s:
3.5v = 67mph
3.2v= 61mph
3.0v= 57mph
