ring end gap factor

No, it definately does not. However, the piston or ring manufacturer would have those handy as with those extra sources of heat, the effect on a ring will be determined by both the boost level, type of boost, and piston design and material. What did those manufacturers tell you?

Nothing. In fact, they didn't ask... so, I asked them.

I learned one thing; you ask 5 people what the proper end gap is for your particular engine (having given them the specs and all other pertinent parameters, such as the amount of boost, etc) and you'll get 5 different answers.

I just tried to hit the middle of all recommendations.](*,)
