The Hunger
The top rings are from Total Seal, and are gapless diamond-lapped versions measuring in at .043-inch thickness. Tom plans to run minimal groove clearance (.001-inch) to maximize the sealing potential. The second ring is a traditional (gapped) ring, and is a low-tension design. The oil ring set is also a low-tension design (8 pounds) that works great with Nelson's bore finishing techniques. This has resulted in no oil control issues and can work with the simple crankcase evacuation system to make crankcase vacuum, saving the hassle of adding a vacuum pump on the street.
