Originally posted by CSVT#49: Well I did an independent study on internal combustion engine intake manifold design my senior year of my mechanical engineering program and I'm not so sure about the statement. It depends on the surface roughness, which will determine the boundary layer thickness. I also designed an optimized intake system for my schools FSAE car as well.
Well, I'm certainly willing to listen to anyone who brings the tech. I find it interesting that you found the laminar flow to be significant, while they didn't.
Those files certainly give some more insight into what I was describing earlier, about why our sitem works the way it does. Certainly the FSVT design will avoid flow separation much better than the Contour manifold. My question now is close to the original one posted here:
Is there any way to make a dual-length manifold with the same runner volumes as the stock piece, but without the sharp bends?
I just don't see how we have the clearance to do it any other way, but if someone wants to do a lot of cutting, bending, and welding, it might be worth a few hp. The 3.0L intake might serve as inspiration: how does it change things?
