Random misfire turbo car
I have a Hellion Twin Turbo, E85, aux fuel pump, 1le factory pump, sbe and stock cam, 95lb injectors and meth. I have random misfire at 11lbs of boost not 7 or 8 and very rarely at 9/10 but when I go to 11. Looking for ideas. I have ceramic spark plug wires, stock coils, and ngk spark plugs gapped at .030.

You are spot-on ttshovel...
Just returned from my tune session yesterday and we replaced the plugs with NGK 3346 BR7EF. It was a hell of a trip to Houston to MS Tuning because I never had an issue and on the way there the car died several times do to a misfire. Eventually several of the plugs failed and I literally rolled into an Autozone parking lot as it died. I wasted $78 dollars on plugs their 7397 NGK Iridium. It got me to the shop (even though it did misfire once). As soon as I got there Matt replaced them and the gap is in fact .025. The tune session went great and I was happy with 813.8 WHP with 12.4psi boost on E85 with the hub dyno. I bought a HPTuner for data logging as well because there are still some tweaks I will send back and forth to to Matt. |

From what I have been reading is that the spark can be blown out if there is too much gap with boosted motors. I am more a novice but was curious about that myself as in what would have caused that. I will also add the second set of plugs I purchased also failed once on the last leg of that trip. The 3rd set of replaced plugs on the return trip had no issues but that was with a new tune as well. I really wish I knew what caused it myself so I knew what to look out for.

Sounds like an extremely bad tune likely drowned the old plugs in fuel or something.
