[QUOTE="singlespeed, post: 97019, member: 264"] not realy ;) For running nitrous occasionaly, it would mean some compromises on the conventional tunning so maybe not as good as it could be when not on gas. Ignition advance isn't a good idea on nitrous, so setting optimum advance off gas would probably lead to detonation. Nitrous runs hotter, so a cooler spark plug is recomended so the tip doesn't start glowing and cause pre-ignition. RS133's seem to be picky over their plugs so this one bothered me. The extra heat needs to be conducted from the exhaust head, so the planned 3 angle seat cut would have been left with a wider seat Cam timming/profiles would be another compromise as NA and nitrous have different needs. High comp pistons and rods would only make the above compromises more evident [/QUOTE]
