A lot of engine builders now are running the second
ring gap at a couple thou larger than the top
ring gap to reduce ring flutter... if it got past the
top ring you dont want to hold it back and cause any
flutter to both rings.... this is what I've been doing
for some time now

that makes sense

have you noticed any differences since you started doing this?

I know one of the best Hi Po machine shops and high end engine building shops in SO CA that use the 2nd gap bigger(.002 to .004) than the top gap policy I have also for the last ten years I started that when TRW, Speed Pro started recommending that procedure
