When tuning wet kit AFR with fuel jets... How much does changing a fuel jet by 1 (or .001) change your AFR?
I'm sure it'd vary with the size of shot, so lets use a 100 hp shot as the baseline. Throw your past experience out there. Where did you start, how much AFR did you have to change, and how many increments did it take on what size shot?
I'm actually starting with a 50 hp shot for first stage and 125 for second, but will probably work my way up to a total of 200 hp thru the two stages over this year.
I have a racetronix intank, Delphi/Lucas 37# injectors (43psi@4bar), Dynojet Wideband Commander, and an electric fuel pressure gauge, so I can dial it in pretty precisely.
