We jetted it up and lost power, so I don't know that I'd call that lean. Stoichiometric ideal for gasoline is 14.7 and we averaged 14.31 so we were probably at max power and ideal jetting in a dyno environment. There is a big difference between the primary and secondary fuel flow even though the carb was square jetted so I'm not sure if the fuel turbine is not quite up to task or if that was actually engine related. If it's a turbine issue, that could effect the AFR printed on the paper. We were reading plugs and going off power produced. - - - Updated - - - Thanks, I think there is still some power to be had as we didn't even pull past 6500 and it just started to really move the air at 6100, but that torque curve is super flat peaking at 690ft/lbs so it'd be a real animal in a street car.
