Second, The air filter restriction also plays a huge part, not to mention intake tube design, maf location, throttle body style, head style, valve size.
Third, humidity and air temp need to be accounted for.
Forth, Also pressure IS NOT flow.

Also as mentioned, a larger the exhaust restriction would mean a higher intake pressure up to atmospheric, at that point if you have your **** together as in cam, intake, and exhaust you can and should build "boost" in the intake. infact, that is what all the N/A guys should be shooting for.

Runner length, runner taper, plenum volume all play a part in many theorys. Most common is helmholtz theory. Where as pressure waves are tuned via intake to maximize volumetric efficiency. Unfortunately, your map will not show any signs of this theory (or any other) actually taking place.


To me this all seams like a bit of a waste. you will not get any useful data from ten different people, with ten different set-ups, in ten different parts of the world.
