What cylinder finish has been successful with the TS "gapless" top rings?
I am interested in that also. There IS some recommendations on the TS website. It makes sense because it changes with different hardness of different block/liner.
Been running back cut top and second napier rings for about 8 years and all's well mostly street and several passes down the track..........No vacuum pump just a good ol pcv valve mid 9's and 6.15 in the 1/8 so far and my plugs look great as well...........12.1.1 comp 170 cranking if it matters...........
