I have been getting a lot of interest in this intake manifold along with many requests to produce a "Dual Plenum" intake manifold. I've been doing some research and came up with the following data supporting a single tappered plenum:
Here is some flow testing that was performed on the above manifold:
Virtual Works
--------------------------------------------------------
Cylinder 1 - 334.2
Cylinder 2 - 333.9
Cylinder 3 - 334.7
Cylinder 4 - 334.1
Cylinder 5 - 334.6
Cylinder 6 - 334.5
Average - 334.33
Variance cylinder to cylinder - 0.2%
Efficiency - 92%
My question after seeing these flow numbers is there really a need for a dual plenum manifold? What is to be gained by doing so if you can get such consistent flow cylinder to cylinder with a tappered single plenum?
