DUAL PLENUM MANIFOLD HOLLAA

Flowbench testing manifolds is of limited value, it can show some potential problems with a manifold but not all because in a plenum type manifold under running conditions, there is a lot of interaction between runners and these are conditions that can not be replicated on a flowbench.

i was also thinking the same thing.....particularly with intake pulse reflection and dynamics that only an operating engine can test

but if flowbenching is cheap enough...its still worth a shot

To put it another way, a manifold that performs poorly on a flowbench will most likely perform poorly on an engine but a manifold that performs well on a flowbench will not necessarily perform well on an engine.

A flowbench is useful for determining how restrictive a manifold is, whether or not the flow through each runner is fairly balanced although that is somewhat effected by the interaction between runners and the plenum so it's only good for showing gross imbalances.

awsome stuff here

you would be better off getting exact dimensions and put it through CAD, a good program will show you flow and cylinder volume

Nice
