An air to air intercooler would be hard. An air to water unit would be a
lot easier. You put a heat exchanger in the intake manifold and pump
coolant to and from a radiator at the front of the car. This is how Jaguar
fit an intercooler into the XJR. We're doing something similar for the
$2003 Challenge.

Propane is liquid in the fuel tank. At atmospheric pressure propane boils
at something like -44 degrees F. Frostbite happens.

Good questions. You'd have to decide what octane rating you want and mix
the percentages. I would guess you could get away with hotter plugs.
Toluene doesn't like to ignite when it's cold but I think that's only a
problem when it's not diluted with gasoline.

If you don't need 117 octane you'll save money if you buy toluene in 5
gallon containers (or 55 gallon drums) and mix your own. I'm not sure what
the tax/legal issues are for a street vehicle. I wouldn't put a sign on my
daily driver that says "Save tax: mix your own fuel".

I said more than 10. I didn't say how much more... ;{)
