Great thread Guys!! I can visualize how segmented bends can cause flow separation at the inside-corner walls and create turbulence, (aka "tumbling" => backpressure). I've been trying to keep them to a minimum, but sometimes that is all I can come up with in a pinch.
I realize now I probably have 10x more weld bead than needed, lol. It is great to see others handy-work for guidance.
What is the deal with stainless over aluminized? That the corrosion is less? It seems it would only matter on the inside, where you can get more buildup from the carbon / oxidation??
If you're in the PacNW / Left coast, I like this outfit for raw mandrel bends / V-bands at at decent price: http://store.racing-solutions.org/
Austin...20-30 hours of cutting and Tig'ing...huh? I was wondering how you were able to do those collector cuts and make it come out perfect!! Very Nice Job.
rdelat, I've always admired your builds. Thanks for posting up that photo Man!! ...that last one is an S130
