In North America, a common option for a dedicated or straight propane
option on older cars was the Impco CA425 mixer. A mixer becomes a
carburetor when it is fitted with throttle valves. For the larger
American cars that could benefit from propane operation, Impco
recommends this mixer for up to 450 CID engines. This mixer is rated
for 460 CFM @1.5" Hg but this may in practice be restrictive for big
block engines. It should be quite suitable for engines such as the
Chevrolet 350 CID (5.7 liter) engine. The shape of the gas jet in
Impco mixers controls the fuel mixture so that it becomes richer as air
flow increases. A different gas jet is available for larger engines
(over 370 CID), which is leaner at their higher air flows. Even the
fuel mixture may be leaner at higher flows, it really means that the
fuel mixture is closer to the ideal fuel mixture required to achieve
the best power and economy. Rich fuel mixtures in gaseous fuels,
unlike with gasoline, result in detonation and burned valves.

>From the information we have been able to find by searching the
internet, propane-carbureted race cars are very uncommon. Richard is
one racer we have been able to find. You may find more information on
his web site: http://www.alternatefuelsracing.com/. As a racer,
sponsorship is always welcome so don't be shy to put your name on his
car.

However, one great way to take advantage of the potential of propane is
through turbocharging. The turbocharger overcomes the loss in
volumetric efficiency and the higher octane rating of 104 allows higher
boost pressures. Ak Miller of California was the one most known in
doing a lot of development of turbocharged propane engines in the
sixties and seventies and Jay Storer features him prominently in the
turbocharger chapter of his book.

Nowadays, with modern vehicles being equipped with digital fuel and
ignition control and port fuel injection, sequential fuel injection of
propane overcomes the volumetric efficiency disadvantages of the
propane mixer. Digital fuel and ignition control is a feedback control
system. The engine's computer has a preprogrammed plan for controlling
the fuel mixture and spark advance as a function of various parameters
measured by sensors in the engine. The O2 or Oxygen sensor in the
exhaust, for example, tells the computer how much to correct the fuel
mixture to the target mixture. A far better means than the best guess
provided by the manufacturer in the design of the shape of the gas
valve or the size of the metering jets in the carburetor. Impco and
Dual Curve both offer feedback systems for controlling propane
fumigation carburetors.
