John;
Lowering the temperature of the fuel increases its density but not very
much. Lowering your air/fuel mixture helps much more. In a
supercharged/turbo system, getting rid of the heat of compression with an
intercooler boosts BHP and also reduces the tendency toward detonation. A
cooler mixture also allows a somewhat higher compression ratio.
I think we're rediscovering much of the stuff that was originally developed
for WW II- era fighter reciprocating engines-- nitrous oxide, water/alcohol
injection, turbochargers, intercoolers, etc. Looking at some of the tricks
that were used in the Rolls- Royce Merlin & Griffon, Allison, D-B, and
Junkers Jumo engines can be instructive. It can also let us know that we're
not as smart as we thought we were-- those guys did it first over 60 years
ago.

As an old drag racer who never used one of these (alcohol & nitromethane can
ice-up an intake in no time flat). Whatever happened to the cold can for
fuel lines? Would this help do more than prevent more that vapor lock?
