well i know i need atleast a 3s lipo to get much faster, but I dont have a charger for 4s, so 3s is the limit. I have a 3s right now, it doesnt really fit the battery tray but based on the speed tests i have done with the gps, i ratio'd out the speed I should see with the 3s and even accounting in a 10% reduction for increased wind resistance, I should still see about 68mph.
i think you might be thinking of a true stadium truck and its setup. my truck is technically called a stadium truck, but its slammed and heavily modified. the drivetrain rotational mass has been reduced by about 40 grams ( i think that includes the cvds, but cant remember at the moment). the truck is lighter than a tc4 in race trim.
