Without trying to be an asshole, how exactly does this advance timing??
My ground strap is a tad further down into the dome as well, the spot where the plugs tighten too was machined a few thousands to get a nice flat surface to my stocker head could be cut, Oring'ed and re-cc'd.
That would mean my timing is advanced by the plug, the plate and my dyna.....
Are you trying to say that because the plug is in the dome further, the fuel has less distance to travel until it's ignited?
Don't think that's gonna make a difference...
However, it will raise the compression...albeit very, very slightly. Maybe a few PSI at best.
I've only run Champion plugs in a total pinch...out in the middle of nowhere...
I've run NGK, all different series. EG, EGV, ES, EIX, Bosch, Splitfire, Nippendenso..and even the famed "Autolite" plugs....that were supposedly the ticket.
And I'm right back to BR9ES...
