Sounds like a good motor combination. What size fuel pump are you running? I've been using nitrous for many years now, and consider myself fairly educated with the 'ol laughing gas. Unless running race gas, any motor should have the timing retarded down to 8-10 degrees btdc when running a 125 shot or higher. I'm just curious...how come you don't retard your timing at all? You might not see any signs of detonation just yet...but you could be doing damage to your motor that shows up down the road.
