Not Ranked
Dyno Results
Hello Niles,
The A/F ratio is a little low, but it is Air/Fuel. That means a smaller number indicates less air, ie: richer. You could maybe get another 10 HP from carb tweaking. The telling info on the sheet is the vol effiency of 93%. Notice that your torque curve is pretty flat and so is the V/E. They are very related. A V/E of 100% means that each cylinder sucks in it's complete volume every stroke. The amount of fuel and air in the cylinder determines how much force that cylinder will contribute to the torque output. If you increase the V/E you will increase torque for any given RPM that you increase the V/E. The main ways to do this are the cam specs. and intake/head design. Your cam is close to mine and I would expect peak V/E to be about 96-97% (Race engines can get to 105% or more but the peak rpm goes way up.) I supect your intake manifold and or heads could be improved to have better flow.
I did the math on you SCFM and calculate that you must have a 451 Engine (about). If you don't something is wrong with the dyno sheet.
