OK LS enthusiasts, here is a simple question about intake manifold design. What is more important: airflow or runner length? It’s obviously a trick question, as they are both important. Maybe a better ...

For years LT1 enthusiasts have been running well into the nines with factory LT1 and LT4 intake manifolds. With some porting the factory castings have proven capable competitors, even on big-cube and ...

Editor's Note: As inanimate as intake manifolds may appear, they provide a path to both major and minor on-track power gains. Selection is one thing; "tuning" them to specific applications is a blend ...

A stock LS3 rec-port intake manifold is hard to beat and only costs $299. When Chevy went back to the drawing board after the success of the cathedral-port Gen III LS1 small-block V-8, it realized ...

In this study, the effect of intake manifold geometry on cylinder-to-cylinder variation was investigated considering the volumetric efficiency, early tumble development, turbulent kinetic energy, and ...
