I like to be smooth and not have a motor make power like a lightswitch when you just tap the throttle.
The 5 port has the most low end torque, followed by the 7 port. The 3 port R from what I hear is very smooth on the bottom end (depending on pipe and clutch set up of course). Most people running truggy go with the 5 port and 086 pipe. This is plenty of power for any truggy. If you want a smoother power band down low in the truggy go for the 7 port with 053. Even though it's smoother on the bottom end it still has heaps of grunt for a truggy.
3 port R is better suited to buggy, and the 7 port is also a sweet buggy motor if running a medium to tight track.
