Default Spark plug gap?

What should I gap the plugs at for nitrous? I had a blower on mine so I'm not sure what it should be without one. .042 about right? I'll be picking up a set of NGK's today.

.042 is probably fine. I went .035 with mine at a 100 shot.

I run .035 on my supercharger setup. .042 should be fine depending on the fuel like 5pnt0gt said.

Later,
Derrick

.042 is probably what I'll set them at then. Thanks guys. I set mine at .032 running 10 lbs of boost with a 75 shot and it worked great.
