Define “large” gaps. Maybe .040 is a “large” gap.

Once again you read something into something that isn’t there.

Next time I fire up the dyno I’m going set the plugs at .100 gap and watch the power go to the moon.

.040 is a large gap in the forced induction world at higher boost levels. I was getting blow out at .032-.036 on a 2.4 DOHC at anything above 20 psi after a 60mm turbo was swapped on. Gapped down to .028 and holy **** was that one nasty 4 banger.
