I'm not sure where the supercharger stuff is at on JSBSim. Certainly doesn't have a Boost Control Cutout. I'm not working on it - I've only just begun to understand YASim. One thing at a time :-). I'm not aware of any requirement in JSBSim Right now I've only researched the RR Merlin in any detail. Enough for our current range of supercharged models. I don't know if Josh Babcock needs anything special for the B29.
