Since most F1 (Tamiya) has different design to 1/12 .. . . . so instead
good to compare Pan Car(Pro10) and 1/12, so which is faster ?? 
At JV, perhaps ... !! 1/12 is faster because
a) 1/12 has almost same power available (similar motor Turns)
b) much lighter
c) similar grip
And, particularly at JV, for 1/12, every corner is big and wide, so most corners 1/12 can go a max speed. Perhaps ?? 
But then going straight, max speed, and wide turns,,, all the time....
