Bad Misfire at WOT

[Halon]

New plugs, gap em low, let er buck.

Threw in new plugs! I forgot what my car felt like when it was hauling ass.

New plugs made the car run like a champ. Old plugs were gapped as the should at .028" Any prefernce on gap?

What plugs?
I think that is what i usually run .028

I usually have to run .022"-.025" on bigger turbo E85 cars. I have been able to get away with bigger gaps on high boost smaller turbo E85 cars. I really haven't seen bigger gaps help full boost power, a smaller gap will definitely effect your idle and part throttle though for the worse. I have had a bunch of E85 cars that weren't noticeably misfiring but weren't making the power they should, gain good power from new plugs, tighter gap, swapping coils, ignition boxes, etc.

I have a dynatek ignition with a gap at .027 and on the dyno Shane said it looked awsome for having such a big gap. That was even on a stock coil and plug wires with no loss of power up top which I think Shane said is what you see when you are getting some spark blow out on higher boost and HP cars. Dynatek FTW!

I use NGK BPR7ES plugs.

Currently gapped at .028 If these start to suck, I'll gap some new ones tighter.

I have mine at .028 and no misfires yet. I used to have them gapped at .024 on my old setup and didn't have any problems either. I decided to try a bigger gap this time and so far so good.

just take the ones in back out and knock em down a lil bit... Or be high roller whichever.

^Did u just get unbanned or something? he solved this almost a week ago

Ok I lied. The car still breaks up under high load.

Anyone got a working coil I can test drive out? IE come over, take your coil off, test drive me car, put your coil back on.

Anyone down?
