This pic was from last week when my intake fuel pump shut off due to a negative factory pin in the plug corroding and not making a good connection.
Boost 27 psi, RPM 3205, A/F 16.1 total time before it went off the WB scale was .5 seconds basically fuel cut lol
I got luck again after I fixed it I did some testing to check the engines health "leak down, comp test and my crank case pressure data-log on a 33 psi run". Everything is good.
So now I think my spray guided piston design is working and controlling detonation by keeping the flame kernel at the center of the piston even when it auto ignites?
