Honestly, I'm not sure. I haven't spun my track by hand in a long time. I can tell you on my RX-1M track porting made a huge difference in ease of rolling but, I had a lot more holes in the track.
This Powerclaw porting is an initial test. If the track doesn't stretch too much or show premature signs of wear, I may add a few more well placed holes. Time will tell.
I can tell you that I think track porting can free up horsepower. On my RX-1 I gained 200 RPM of shift speed just by porting the track. So, I was able to add more weight to my primary to harness this free horsepower.
