SR spark plug gap

[Nissandriver714]

I've searched and found a couple of link saying I should gap it at .028 in. My car has about 230-240whp and I will be using the one step colder iridium spark plug. Question is, should I gap it at .028? thanks

Stock SR=

NGK
PFR6B-9
gap is 0.90mm which is about 0.035"

more boost, lower the gizzaaapp

I thought more boost = higher the gap. This will create a longer spark between the two electrodes?, thus burning more fuel and air. Correct me if I'm wrong.

The more boost the easier it is to blow out the spark that's why you shorten it from .035". Im at .031" with no problems.

try NGK-R BCP6E11 or stock #6662. There pretty cheap and we use them on all our SR's gapped at 28-30 depending on boost levels.

Yeah u should work your way down mine misfired at .030 then worked perfectly fine at .028. You juss have to keep trying to see were it works best.
