What is the sound of too much timing on the VE pump?
after my 366 spring, fuel pin, and AFC tweaks still running 16psi of boost
prolly a leak)
I decided to bump up the timing a bit.. since it sounded really smooth and quiet after all that work, so I spun the pump a bit.. mark looks about the same on the timing case but I can tell by where the bolts were the pump definitely rotated more to the head. was going for 1/8" but i'm wondering if it didn't go closer to 1/4"
anyways, it's much louder now, and has that distinct diesel rattle to it, almost powerstrokey but not quite. just curious if maybe I went too far and what the signs would be.
EGT is a bit lower, boost is about the same but a lot less smoke, and gained my missing low end power back, plus a little on the top end.
i'll post a sound clip later if that would help. or you can kinda hear it in this vid.
