Propane injection

The vaporized fuel will displace more air than equivalent gasoline.  There will be less air in the cylinder than if only gasoline is present.  This is significant to engine performance mainly at WOT.

After the turbo, I want to have a way of cooling the air, besides an 
intercooler.  THe idea of propane is cool, but i would need much bigger 
inlet ports if i used a significant amount of propane, and I would still 
need an intercooler.

Thanks for the thought though.
