Thanks for the link Dave, good reading.
Very depressing reading actually. I do not have access to the CFD, so it sounds like it would be impossible to get the right configuration with out the software. My design so far is just based on what I have seen and read. I have very little to no experience in fluid dynamics, and I would hate to build this manifold to have it be worse than a simple open plenum design. HMMM what to do, risk it and make one - possible wasting the time and money, or go with what we know and make something like a plenum used on the RB motors.
I hate problems like this when my hands are tied by my limited resources. Making it is the easy part for me. I don't think common sense will work on this project.
Thanks Jeff
