Finn,

Dave=92s advice is spot on. Most of these companies will build what you nee= d for only a little more money then retail. You tell them core / tank size,= fitting size, air bleed, drain location, additional angle for defuser moun= ting, etc.. Build a mock-up out of cheap thin foam board, 5 minute epoxy and toothpicks to determine fit up. = Thrift store foam works great for about $1.00 a sheet. Lightweight and stur= dy. Make a sketch for the manufacture to build the heat exchanger.

500-600 cu in is a good range for a non-boosted two rotor. With a reasonabl= e duct and defuser you can expect between 80F-110F air delta T. Some have h= ad better results. This is where Ed=92s workbook is very useful and helps s= et expectations for core and inlet size. If you have room I would start with a 25-30% duct opening and reduce= if possible during flight testing. Once you have a performance baseline it= =92s much easier to reduce the opening then enlarge it. Or use a cowl flap.

Ed=92s workbook estimates BTU rejection for the core face so I assume it=92= s for the first cubic inch. My 2.75=94 cores with an 82F delta T preform ab= out 35% better than the workbook prediction.
