NOTE: These start out newbie level, but the discussion I'm after is on the advanced side. Methinks this the right place.
1. Is it generally possible to "correctly" time an engine with a balance shaft out of phase?
2. If so, would said engine run right?
3. If so, how would the increased vibration affect longevity?
Reason I ask is:
1. When I timed the G54B in my Pajero last month, I know I got every single mark lined up 100% correct.
2. Now that I've tamed the Flying Spaghetti Monster that is the Mikuni feedback carburetor, the truck runs like a friggin' boss.
3. But above 3000rpm, it starts vibrating like a motherf*cker. I'm talking lumpy cams, solid motor mounts, 2000W sub, & MTs rubbing vibration.
Imagine a giant pager up on the roof. As you wind any gear out past 3000rpm, it starts vibrating the whole shittery.
I've also posted this on the Wire, but figured I'd ask over here too, as it's a theory I don't think we've ever discussed. Everyone knows BSEK doesn't increase actual vibration - just how much is felt by passengers. But if it were possible to correctly time an engine with an out-of-phase balance shaft, I wonder if all the mirror shaking and vibrations felt would pose a threat to the engine.
