It uses 1" sch 40 PVC throughout.No welding, no twisting the oem manifold and rewelding them to point at outlet of VW manifold (like I did) Instead simple hand tools, and PVC material that are very easy to work, makes it really compelling to build one.Then ties into your OEM head mounted manifolds.I would like to try one to see how it works, and for how long.Being that is is all 1.050" ID and virtually no air volume on the center section like out VW plenum has, granted the VW plenum is quite small, charge speed would be extremely fast.But!, I am Not sure if you would start to lose power in upper part of the power band, like top end.I think with the Polaris style adapters you could mount a carb adapter to the Polaris adapter to mount the 32DFT.Dang, I guess i have my papers, I would like to try it.Just because it is so cheap. I could build one then put a second one on my shelf, if you could get a few years out of one it may be worth it. Who knows you may get a lot longer than that, if it were supported, to avoid normal flexing.</blockquote>
