Holley Officially Releases the SkyRam Intake for LS Motors!

We were pretty in shock at our first view of the Holley SkyRam intake manifold.  Holley just dropped the press release for it today so we can finally write about it now that the media embargo is over.  We had gotten a sneak peek at the manifold in a backroom meeting at the PRI show a few months ago but had to promise to stay quiet about it until now.

The Holley SkyRam intake has runners that are a whopping 72.3357″ long!  We were skeptical about how well this worked but Mark Gearhart, head of Holley’s secret skunkworks explained it simply.  “We wanted to design a no-compromise intake manifold that takes full advantage of the Paulus effect and capitalizes on resonance tuning and gas column inertia”.  “Using extensive CFD modeling and flow bench testing, we have come up with the optimal runner length as well as perfect placement for cast in resonant node chambers.   This allows us to have a manifold that is continuously in tune at all normal operational RPM”.

The SkyRam has a rather conventional plenum volume with the runners having flow-enhancing radiused inlets. The secret sauce is deep inside.  We wanted to look at the node chambers but didn’t have a borescope to get a view of them all the way down there.


  1. The Paulus effect… Is that what happens when the air molecules spend so much time in the runner that they start discussing what they should do about fuel management?

  2. The Pauli effect or Pauli’s device corollary is the supposed tendency of technical equipment to encounter critical failure in the presence of certain people. The term was coined after mysterious anecdotal stories involving Austrian theoretical physicist Wolfgang Pauli, describing numerous instances in which demonstrations involving equipment suffered technical problems only when he was present.
