Does an increase in airflow (intake or exhaust runner) move peak torque up or down the RPM band?

Since plenum and runner volume have all kinds of RPM range applications we have to realize that the intake affects everything to do with HP, TQ as well as the range in RPM's that they produce them.
So it's not just the cam that determines.

Maybe I should have said what I was thinkin for your benefit. I was gonna throw in there somewhere "all else equal", but I didn't figure I had to. I shouldda thought about you. LOL Ain't seen you post a lot lately. You doin ok?
