This is our track. Not much of a high speed track, recorded fastest lap time is 37 sec. We use P5 and Plus 4 with 9901 pipe.

Will a KeepOff 4 port suffice or should we consider a 7 port? I know the 7 port is more high tech. I also race occassionally at PRC track, Pattaya-Thailand.

My track buddies have been pushing me towards OS, but hearing mixed reviews. Hope I will not regret the Nova purchase.
