Cheap Fmic's

[Kracka]

There will be no power difference, the only difference will be a slightly longer spool-up time. Think of it this way though, that air is moving 200-250 mph, how long does it take to move 3 feet at 250 mph (3 feet being the extra piping)? The 178 core with long(er) piping will have aproximately the same spool-up time as a 120 core with short piping. As for metals used, SS is the best since is dissapates heat better than does powdercoated mild steel. SS is of course more expensive, so its another trade-off.
