I've been trying to resist the temptation. I can't go with much of a shot however. I'm using a glassy-smooth bore finish with a tight end-gap and a wide LSA roller. And I'm already using the coldest plug I can get without getting into the ice-cold NASCAR plugs which are Gerschtunken for street use. IOW it wasn't built for Nitrous. I think a 100 shot would be a semi-safe max unless I tear into again (and I'm too lazy) But if I pull the trigger, I can sure give you a shout. Thanks!
