Nice that makes sense. Judging from your other posts I take it you're an engineer? If so, what kind?

Oh and op, use 91 at least.

Not an engineer but spent many years as an Instrument Tech at a hazmat incinerator, so I know a little bit about combustion and heat. I also paid attention in Science classes when attending high school.
I also spent some time in mechanical maintenance, so have been around pumps, valves, flow, &c.
I was always asking the engineers "Why'd ya do it that way?" and most of them LOVE to splain stuff to others. heehee
