On 6S, you should be able to gear for 40mph without problems. For constant running, I gear my buggy for 35-40mph (app.60kmh, maybe) But for speed runs, I think I squeezed way more out of it :017:

On the buggy I like "slower" motors and more voltage. 6S is plenty!! 5S works fine for me, too. (correct motor assumed!) Already 14Ni cells are enough for a 1/8 bug.

How many rpm/V has the 1940/8??
