Propane injection.. How much?
I've heard good things about propane injection, but I'm wondering how much you should inject... I'm running about 33 PSI and was thinking of adding propane, and possibly methanol if that doesn't do the trick. To meter the propane, I was thinking of using one of the many NOS injectors I have pre turbo, then having a pressure-matching diaphragm valve, probably made from an old regulator, which would inject propane at approximately the turbo outlet pressure, which would make it inject relative to engine load. I was wondering how big a tank I would need on my truck... would a 10 gallon tank be plenty? how often would I fill it, and does it pay itself in diesel savings?
I've know a guy who did it, but he has a manual valve to control it in the cab... I'm not fond of that idea

injectables arnt really my cup of tea. if your looking for fuel savings this isnt going to be it. you are still injecting FUEL just a different kind. there are less BTU's in propane than diesel so you will need more of it to make up any kind of supplemental difference. propane should be used in my opinion as a power adder only. tank size is to you digression just like an NO2 tank. i would try and sway you to water/meth if you want to inject. but if your not looking for big numbers why inject? DD truck?

I *heard* it helps the diesel burn cleaner... I know a guy who uses it in a big rig with a Cat 550 and his engine oil stays pretty much clean, which is also nice... He swears by it. As it stands now, my idea for it is using a Hobb switch on a propane solenoid, set to 10-15 PSI, and a referenced regulator to inject 5 PSI + boost pressure in front of the turbo. from there I can adjust the actual delivery with a restrictor or by changing nozzle sizes.
