Form and Function - A Look at Intake Manifold Design: Intake manifolds play a huge part of power production, here’s some of the hows and whys Internal combustion engines are fairly simply machines.

OBJECTIVE: Wet flow, pressure excursions, port volume, runner length, plenum volume—all these figure into an engine's overall efficiency. But there's more… Sometimes theory is neat, but sometimes it ...

One of the easiest ways to tune an engine's performance is with the intake manifold. Yes, the camshaft can have a bigger role in horsepower production, but a camshaft swap includes real work and more ...
