Wow, just read the dyno test of the 3 port in rc nitro, and compared to the rc driver dyno of the 5 port, it looks like these are entirely different animals. Amazing that 2 ports can make such a polar opposite engine. Granted, the dynos/pipes/fuel are different, but still, I'm amazed at the difference in power generation. The 3 port looks like the hot ticket for the small tracks in my area. Has anyone tried the 3 port back to back with the 5 to verify the validity of the magazine's data?
So everyone knows, the 5 port appears to be an all rev engine vs the mad torque of the 3 port.
Looks like either one will be the hot engine to have if you choose properly based on your track size/layout.
Late.
