How much gap for nitrous?

My plugs are AR33 just shooting 150

i would start around .045 or less , maybe someone else will chime in , what is the compression ?

9.5to 1 and I'll be running 110 gas

^^^^^^^^ This, a 150 kit on race gas is not going to blow the candles out unless you are running a weak factory ignition in which case -.010 or don't hit the jug until the ignition is upgraded.

Box is a digital it works everything cuts it on at 3000 grand and off at 6200 it also pulls out the timing.

The bigger the hit, the smaller the gap!! You are fine at 150 shot with .035-.045"

ran the stock ford distributor ,elcheapo eglin box with an old Accel super coil , down to 7.60's @ 186 mph ! never a problem !! plug gap at .022" spent $1500 on the greatest latest ignition system , performance gain "0" still ran the plug gap at .022" still ran the same Numbers!!!
