| Looks to me as though they are assuming flow to be steady. Accurately modeling intake manifold flow properties is far more complex than the simplistic approach they've used. You just cannot expect to use an inaccurate model as a basis for design and end up with the expected result. The CFD models look really high tech, but they aren't applicable to the study.... Anyone can do CFD:)
 The difference is whether or not you know how to accurately use it..... :) p.s. Not avoiding your messages on the radiator... We are really close on that product. and it is not held up by patent... :)
