I am currently running a 3 Port R spec in my buggy. I have done some practice on outdoor tracks, but primarily I run on an indoor track during the fall and winter.

How does the low end power of the 7 Port compare to the 3 Port R? I was thinking of trying the 7 Port, but I am afraid the low end power may be too weak on a smaller track. Is one easier to tune compared to the other?

How does the runtime compare between the 7 Port and 3 Port R? I would be running the 0801 pipe.
