Anyone know how far in to the plenum those runners go?
On the HSR? Its runners terminate flush with the base of the plenum.
The reason the tests show more power with a plenum is explained by the influence of Helmholtz Resonance on cylinder filling.
Using the aftermarket throttle body on an HSR plenum may influence the Helmholtz Resonance to whatever extent that volume of the plenum changes. An individual runner intake with four of these throttle bodies would be a different matter.
