My 2 cents worth Guys,
Propylene Oxide 1 : 2 Epoxypropane CH3-CH-CH2.
5% added to methanol gives power increase, adding more dosen't always
further increase power and in some cases power losses occur. Up to 30% can
be added to nitro but results vary according to engine configuration etc.
It is an extremely volatile, highly reactive, highly inflammable clear
liquid with a light odour. Used mainly as an excellent ignition accelerator
especially in nitro. Easy starting smooth running and power increases when
mixed correctly with most fuels. Very dangerous in contact with
copper/alloys or rust, easily becomes unstable and explosive. Has a gravity
of 0.83 and 14,000 BTU's/lb of combustable energy. Info from "The Complete
Handbook of Racing Fuels".
