So upon ChrisD's advise and experience with Global Tech & Engineering, I'm building a list to buy my intercooler pipes.

I'm a bit confused on some measurements though.

Case in point, I'm looking at the 90* bend aluminum pipes in 2.5" 16gauge.

I know what the Tangent length is, that being there's 5" of straight pipe on each side before the bend starts and/or ends.

I'm not 100% clear on what the CLR (Centerline radius) is. From what I've read, it's the measurement from the pipe bend to the center line. Based upon that, does a smaller CLR mean a tighter bend/shorter overall pipe length?

There's the different 90* bends available. I'm thinking either the 3" or 9" CLR, that should be a good size.

Perfect! I guess my geometry skillz are still somewhat alive!

So a smaller CLR=smaller pipe. I'd want to stick with some 3" CLR.

Mine were the 4" CLR versions, which worked pretty well, just clicked Home > Mandrel bent elbows > Stocked mandrel bent elbows > 2.5"

I think that's what they stock ready to ship, the other stuff they bend on demand.
