EFI for Propane

[ScottyCBoy at aol.com]

I've got a question or two:

Has anyone though about or attempted designind an EFI system for
Propane/Butane fuel. I would think that liquid propane entering an intake
manifold at 300 PSI at -80 degrees or whatever it boils at would do wonders to
lower intake temps, plus with a stoich ratio nearing that of Gasoline and an
Ocatne rating of 130 seems like it would be an ideal fuel for super high
performance turbo charged engines.. Not to mention the fact that all those EPA
CARB guys would love Propane's low emmision exhaust gasses. Has anyone found
an electronic fuel injector capable of withstanding the high pressures and low
temperatures for such a setup? 

Thanks!
