Supercharged Gas Vapour Injection

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.
