Here's a nice concept... I assume that with the 1:250 volume change, that liquid injection is both fiddly, and incredibly expensive to find a system that meters fuel so accurately?
Or I could be wrong.
How do people gauge the difficulty of converting a RV8 EFI manifold and systems to run on LPG?
Anything as simple as replacing the fuel supply with a liquid propane feed?
The injectors and manifold will be very hot when running so I assume injector freezing would not be a problem?
Any other problems - I'm quite tempted to try it! OF course if I meter too much gas in it's bye-bye block casting!!

Vialle do such systems. Not cheap, but the best. Nearly bought a second hand one a few years back.
The expansion ratio is a non-problem. What is a problem is the pressure that the system runs at. You need 2 tanks, low pressure and high pressure and a fairly trick pump. Injection timing isn't a problem.
What is good about liquid injection is you gain the big benefit of LPG. As is vapourises it cools the inlet to -30C. Provided things don't ice up you get up to 30% more air into the cylinder. 10:1 CR and a turbo? No problem.
If you can afford it, do it. We will all be jealous.
