Jet Size/ Boost (A63NovaSS?)

[enkeivette]

Now I know that all motors and all carbs are different and there is no good generic answer to carb tuning, yadi yadi yadi. But is there a general rule for upping the jet size per lb of boost. Example: up the jet size 2 points for every lb of boost... something like that?

Found a Chevy Hi Tech article where they were testing a Procharged SB, similar to mine. First run they were lean 14.5:1, like me, they upped the jets 3 sizes on the primary, 9 sizes on the secondaries to get it down to 12:1. I jetted similary, I'll check my plugs in a few days and see how they look.

Maybe someday when I have my precious LM1, I won't have to judge AF ratio like a caveman... A man can dream can't he? :sm_laughing:
