I'm waiting until the ring seats for both test. Copsey did the comparison. 5%gain cut time. 10psi gain. IMO the gain will increase. Not bad for drop in performance. Thing with a 1mm ring is they usually don't show a true static comp reading. Once running, its different. Take longer to seat also.
Gotcha. I noticed that with the dominant piston. Looking forward to hearing/seeing more about this 346 piston.
