I bought my first Vulture in the old days, before Engineering was a thing. Power was limited, as you say. However, 2 large pulse lasers worked fine, and at the time they were quite powerful against the NPCs. I did a lot of bounty hunting in RES sites and CGs in that Vulture, saving up for a Python.Unengineered, the PP struggles to deliver enough power for its core components - no weapons installed, yet.
I have a fully (if strangely) engineered Vulture now that I call Bunzilla. This one features 2 overcharged multicannons with Incendiary Shell on them. And 1816MJ worth of shields. Power is less of a problem now. The MCs aren't as effective as I'd hoped they would be, but it's an amusing ship nonetheless.
I've never really noticed the engine sounds much. I guess they don't bother me. I do tend to keep the sound on my computer fairly low, though.
