Help interpreting dyno rsults

[Smoke ring]

Your doing pretty darn good as your using 243 cfm of that 253 to make that 502 hp, but that also means your just too high in port velocity due to your minimum port area where ever that may be , as in Heads or Manifold.

If it is in the heads then if you can increase the Intake Manifolds expansion rate back towards the Plenum, or grind some in then you will slow down the rate of velocity increase and raise the rpm of peak TQ and have a greater HP level in turn.

You also badly need compound curved injector extensions with that narrow V to get them the Hell away from each other and then as posted Bell inlets on there ends!

If I interpreted that correctly it means when a heads csa is tighter than the engine wants you can bandaid it some with larger taper area in the intake manifold to try to slow down earlier velocity in that area to help things?

Yes, to a extent you can delay the rpm at which the whole Intake tract velocity shuts down your power production to a higher rpm.
This will give you a narrower power band that will help out in the higher rpm ranges, but trade off from the lower range.
If your building something for let's say the Engine Masters challenge where average numbers are important you need to see if the gain in top end power offsets your drop offs down low.

I wouldn't bet on it workin out that way.
