nitrous afr
nitrous afr quick question, if a car na has an a/f of 12.6 and you put a wet kit on it. say 140 shot, 56 nos 31 fuel jets, lets just say that with those jets the a/f stay at 12.6 while spraying. how rich would it get if i upped the fuel jets to 32,33, or 34. does anyone know what would it take to get the a.r down to 11.5, yes i know a wideband would be beneficial. but just looking to see how fat or lean it gets changin 1 jet size on the fuel side.

Try going up to the 33 jet. Start richer. If you dont want to get a wideband learn how to read your plugs. People were tuning cars and running all kinds of nitrous set-ups long before widebands exsisted. I know how to do both and think the wideband is a lot easier. Still look at the plugs from time to time though.
