spark plug gap for 18psi

[kicker22705]

for those of you running high boost as in 15-20psi range w/ bigger turbo, what are you guy gapping your plugs at?

i have mine gapped at .032 w/ my ngk zfr7f now, but i'm only running 10psi right now.

i plan on boosting 15-18psi when i dynoutune my car on friday and don't want to run into issues of blowing out the spark.

thanks.

Can't give you a solid answer but to give you an example...I'm at 10psi/spike 12psi and gapped to .030 with no issues. I would imagine you need to be at nothing more then .028.

I have my plugs gapped at 28.
