CNG is cheaper to use but the start up cost is high and its difficult to store a lot of CNG on a car or truck.
I wouldn't mind running propane again but I think my compression ratio with turbo is too high, if I did use propane I would only be able to use it in say the 2-6 psi of boost range.
I have considered running water methanol at lower boost.

I think I would be better off running water methanol since it would enhance the temperature differential between both the hot and cold reservoirs. The evaporation of the water methanol makes part of the cold reservoir cooler, then when the diesel is injected and lights off the methanol, both burn off and help make the hot side hotter.
