28-30

depends, my car runs better at .22-.25

if your running stock ignition .28, if you have a MSD 6L or something you can run a little wider gap. all depends on how much boost your running and what kinda plug.

I never ran tighter than .32 even at 13 psi with NGK BKR7E plugs anything tighter and the car ran slower . Anything wider and it blew out the spark.. This was with a MSd cap wires and Blaster SS coil.

I have been running 6-8 psi daily for a few months and there wasn't much of a problem, except for a little hesitation with boost transition. After starting this thread, I gapped mine to 30 and i immediately noticed that i was starting to run a little leaner. Is this normal?

I'm running .28, but everyone's engine is different. You'll just have to try out different gaps and see what works best for you.

I"m running .28, seems to run fine

I think everyone means .025"-.028"

.28" is a lot and .28mm is not quite enough

yea i always notice people saying .28 or something when its .028. I say anywhere between .028-.032. I run .028 @10psi personally.

I always ran with a stock gap, why close the gap if the spark isn't getting blown out?
