    Anyone running this set up on an open plenum style manifold?

    My gas is vapour EFI, plumbed into the lower intake manifold. If you can get the tune right, it loves boost.

    I hit 10psi through a FMIC last night, after finally sorting out my Romano system after a year, it held 12.5:1 to redline!

    so you are running the std lower manifold right? I'm talking about the open lower manifold used by PD superchargers.

    Good to here it is running well.

    I believe there is an issue with not having long enough runners that causes gas scavenging to other cylinders.

    A friend is looking to run an Eaton on his LPG gas vapor injected car but has been told the lower manifold will require tubes welded into it.

    I was just wondering if anyone had successfully run gas vapor injection on a PD supercharger with an open plenum.

    Yeah sorry, stock manifolds. I remember Neil kept telling me either style will be okay (PD or Centri) but I'm not sure what he had planned for the open manifold.

    Yeah it's chalk and cheese, that last few thousand rpm is just awesome. And that's in a 2.2t truck!
