a lot of it depends on setup, but there is a noticeable difference in power between the 4mm and 10mm cub motors.

Usually going to a better chassis will get you faster times than upgrading your motor on a stock chassis. I know of a 397 Cub that has run 3.72, but his complete setup only weighs around 220 lbs. Weight (and weight transfer) is everything.

 

That being said, I ran 4.08 on my 4 mil Cub in a 315 lb stock chassis, and took me a 100 passes just to get in the 4.08s in a 250 lb strutted dune chassis.
