Can anyone tell me how this works? Not finding information on it anywhere. I'm having a problem understanding how a positive displacement supercharger works with AFM, considering the supercharger pushes X amount of air into the intake with each revolution of the engine. When AFM cuts the engine in half, it seems to me like the active cylinders are now taking the same air meant for 8 cylinders, which should increase those cylinder's compression by quite a bit. GM sells the LT4 with AFM active, and they seem to make it work.
So, how are they making AFM work without screwing the engine up? I'm in the initial planning stages for a 5th gen LT1 based 427, and I may at some point want to supercharge it and if I do I plan to keep AFM active. I know a lot of folks don't like the system but I do.
