PRP Velocity Lessons
Not a head porter, nor did I stay at a Holiday Inn Express last night but my understanding of the "Your flow bench is lying to you" refers to a couple of things.
1. Engines don't run at 28" so it's not really representative of what's going on in the engine.
2. Engines don't run "dry", see #1
3. Max flow doesn't mean Max power.
I'm sure there are more reasons, but again, I'm no expert. I sit in the corner and watch them and learn.
