Engine Masters: 4×5 Season 4 Episode 5 HydraHD

Pressure Testing the “Blower Manifold” Debate

On this episode of Engine Masters presented by AMSOIL, David Freiburger and Steve Dulcich welcome back Richard Holdener to blow the literal lid off of internet “blower manifold” theories. You’ve seen us play with runner lengths before, but this time we use FAST’s modular-runner intake manifold to test both short and long runners to see how each reacts in both NA and boosted trim. Is there such thing as a “blower manifold” or is it all just keyboard huff and puff? Join us to find out, won’t you?
