possible spark blow out

[highball69]

i just installed new screamon demons and live wires.
i also went with 1 step colder ngk plugs but now i think im getting some blow out.
i gapped the plugs at 34 demons said u could go up to 50 (i know thats rediculous).
this only happens at around 5000 rpm,s and higher. boost is at about 7 lbs.
any help would be greatly appriciated.

OK, CSS ricer post, lack of info.

Little info on the combo, for all I know you are feeding 7 psi to a 427 side oiler.

What are you doing for fueling?????

Close the gap to .025 and report back.








and WTF are Screamin Demons.........White Castles????

demons r coil packs.
its a 4.6 stroker, full port heads. its built with bout everything i could throw at it.
i upgraded the fuel pump and added a boost up pump. not having any fuel issues.
i have the procharger putting out about 12 lbs now.
i was mostly wandering if their was anything else that controlled the fireing that maybe i overlooked that needed changing?

well usually your problems come from the last mod you performed. Since it wasn't doing this before, and you changed the coils and plugs and wires, chances are the problem is in there somewhere. Start replacing the new parts with the old ones until the problem goes away, and then you have found your issue.

Cannot use stock gap.....close'r down a bit!

Said he's got them gapped at .034, which for his mods and such is plenty tight.

Are you running any type of fuel additive? Some kind of octane booster maybe?
