Hi all. I'm an electrical engineer and I was tinkering with some ideas....
For electronic circuits, signifigant development has gone into simulation programs... basicaly because circuits operate by following known physical processes we can simulate a circuit's behavior on the computer with great accuracy. In the simulation tool, each circuit element is represented by a table of values that determine its operation.
Like electronics, engines also operate based on known physical properties.
carburetor flow rate vs rpm,
intake flow rate,
head flow rate,
exhaust flow rate,
type of rings and friction assosciated,
etc etc.... all of these things go into an engine's operation
so.... given ALL of the specs of the engine, one should be able to simulate an engine's performance on the computer and optimize it to get the best performance.
To make this possible, when a head or carburetor is sold the numerical values that determine its charactaristic operation should be included.... then you could just pop in the values for the part you have into the simulator and see how it will affect engine performance.
Once all known parts have been charactarized, it can be simplified by using drop down boxes in the simulator to choose your part, then simulate....
A good step further would be the user would input what RPM he wants his powerband to focus on then tell the computer what heads, carburetor, CID , rod lenght, pistons, exhaust, valve sizes etc he has and it would calculate the optimum cam specs. Then he could give those specs to the cam builder and have an optimum setup.
Does anyone know of this sort of thing going on? Would any of you guys pay for a program with these capabilities?
