My early SR's were livened up years ago by the talents of Nick at Compu-flow and as a standard port window made some decent power.
BEST machine later on advised me that if a Max window and port were to be introduced, it would be a whole other world, but I stubbornly stayed in my ballpark till this day because I wanted to keep a small window and see what decent torque it could still muster in the lower lifts. Since then, the technology has changed for the best of both worlds and I guess I have to come up to speed literally.

I street drive, so low lifts is where it lives most of the time.
