You're Gonna Need a Bigger Plenum...

9th October 2019 Season 4 Episode 10

Well, maybe. This time on Engine Masters, presented by AMSOIL, we dive into what effect changes to your intake manifold's plenum volume will have on your motor. We want to know if all of the Internet's theories about big boost, big cubes, and/or big rpm needing bigger plenum volume really hold water. Will all of that increased volume really turn into increased power production or are you just creating hood clearance headaches? Watch as we go from straight out-of-the-box to out-of-the-bounds-of-sanity with this plenum volume comparison.

Big-Inch, Big-Power, Big-Block Manifold Shootout

This time on Engine Masters presented by AMSOIL, David Freiburger, Steve Dulcich, and Steve Brule´, go on the hunt for the best manifold to make big horsepower numbers on a big-inch, big-block Chevrolet. These aren’t manifolds for any boring, old 454 or even a 496. We’re talking 598 cubes of big-block, and we’re throwing four different single-plane, single 4bbl manifolds at it from Dart, Pro-Filer, Brodix, and Edelbrock to see how the difference in their runner walls and plenum shapes make or cost power.
