Supercharged LPG 2.1

[Pickles]

I AM WANTING ADVISE ON BUILDING A 2.1 SUPERCHARGED LPG
i have a dj ready to build it will be run on LPG virtually all the time
I have the dj and a mini eaton supercharger.
What compression ratio should I run as I will be using 112 octane fuel lpg
I am currently running 8-10 furthe advance on my current DJ
what does any body recommend
I am wanting to use the cooling properties of the expanding gas as an intercooler any ideas of combining the vapouriser / intercooler
Do I need DG pinsons to lower cr

Any ideas welcome

Can only add to that statement above, when I do any of the turbo vehicles or supercharged vehicles they must be injected gas not through a venturi, you can run the "Dream C" sequential quite successfully on any blown engine, the requiremtns to fit this is
1. A lambda probe
2. A TPS (throttle position switch)
3. A TSS (throttle stop switch)
4. Negative switched injection
More modern vehicles we use the "Dream N" where the TPS and TSS are negated by the injector timing from the ECU, the gas system becomes a slave to the petrol ECU.
If you tried to run a venturi the gas would just feed back under pressure and you would have one hell of a bang.
