air fuel ratio with boost
 
Just saw stock fuel map for a ZR1 vette engine. 9:1 static and 10psi boost. Anyone wanna take a guess at what the stock wot Afr is under boost ? :)

What year ZR1? I am going to assume around 12.2:1 or leaner.

i,m sure they don,t run it on the ragged edge .i wont guess because i know the answer but don,t want to cheat.

Ok I don't wanna jerk anyone around.

10.7 at 4000rpm

Above 5000rpm 10.4.

funny thing,when i mentioned running 10.5 on a 1200+ hp engine some members said i had no idea how to tune an engine.i guess gm engineers don,t have a clue either,lol.
