You could make it out of mild steel. Cheap, easy to work and weld, and reasonably ductile for absorbing a backfire. Plate it for corrosion resistance (HPC, zinc, whatever) and it will also add some weight to the bike as well.

I built my plenum from 6063 aluminum extrusion with a 1/4" wall thickness. End plates are welded on both outside and inside. I'm very lucky to have an extremely skilled welder able to do that.





You can source a few different 6063 extrusion shapes here: http://www.rossmachineracing.com/plenumextrusions.html

You will notice they don't sell any thinner plenum material.  rolleyes

Nice Hombre!

My first plenum let go after a wicked backfire, scared the hell out of me.

I suggest making it considerably stronger than necessary, it also helps if you need to tap into it for fittings or BOVs or what have you. Aluminum is light, cheap, corrosion resistant and strong if thick enough.

How about a "pop-off valve"........they are adjustable to various boost pressures and prevent "blowing up" your plenum in case of a back fire..............................................................................................

Thanks, Dean... that might have hurt if you'd been laying directly on it!

True. But once I figured out that the aftermarket "heavy duty" valve springs were actually weaker than stock, I corrected the backfiring issue. Great learning experience.
