Hi all
Im working on my corsa down here in aus and am toying with the idea of a custom plenum
While i have no background in metal fab, i am doing an acoustics course and the math involved with finding the affected rev ranges etc is simple enough and i have access to simple metal fab tools and and uncle whos a welder
My questions are, does anyone have any tips or preset measurements to go by for this engine?
Do the cylindrical plenums work as well as welder rectangular?
Ill probs have more questions but for now thats all!

Surely it would all be down to getting a smooth airflow into the cylinders but also getting the most air into the cylinders. So in my opinion i would say that cylindrical inlets (plenums) would be better but a welded rectangular is just fine as they gain 10-20bhp which is good enough for a decent gain.
