Plug gab with MSD
What is everyone increasing their plug gap by when changing over to MSD ignition? It says that it can be increased by as much as .05, but it also says to play around with it. Well seeing that pulling plugs from a 911 is a little more involved than others I thought I would ask so as to get a good starting point. I have a 2.7 with SSI and no emmissions.

I went through that saga, dont go much mo9re than .010" extra on the gap. Mine would barely run at an extra .020". Then again my 930 has 6.5 to 1 compression so you may be able to do better.

MSD recommends testing at .005 intervals.. and when power falls off, it's to large.........Ron
