20% LPG Power and Torque and Mileage increase??

Rumour here, new Technology of injecting LPG metered amount into the intake manifold for fuel economy... Anybody done it? No one has tried here on Effies yet... The LPG gas injection to diesels is not new, Interstate trucking has it on some... What about a Powerstroke? Anybody tried it...?

LPG is Government subsidized here in Australia, and now there are Incentive packages to make the change... Cheaper fuel, better economy, all the right reasons..



What cha think?

Thanks in advance, what a great Forum!! Ranger in Oz...

Hello Marc, you tireless Ford Guru you... What is the process of the water/meth?? How does that work?

Is this just because of the corn/grain alcohol prevelance in America? We don't have that here in Oz, but we ARE LPG rich and the government is subsidizing conversion and LPG... Is that why your advice to go water/meth is the easy to get fuel?

Doing research for our 90 or so Fords running in our Bushtracker Group in Oz..

Best Regards from the Ranger

Lpg makes good Hp numbers in a diesel pickup,keep in mind you are using 2 totally different fuels with different flash points.in our testing at BD we ndetermined that pre-detenation was not worth the gain in HP or savings.
Long term shortens engine life.short term saving gone .Pay me now or pay me latter.It's your money.
have a pint for me mate .

Well thank you for that Harald, and Cheers... Beer is on me, come on down..
One elaboration if you don't mind... Put your test results in line with Oz standards, Cheap LPG and government subsidized conversion, is it workable with only a smaller injection percentage like maybe 20% or something??? Or are you still thinking it is not worth it... And what wear on the engine are you anticipating? Valves? Guides? Pistons? Rings? Lower end somehow..? Not trying to pin you down or question your expertise, but I am doing research for my Mob of Ford Enthusiasts towing big rigs here in Oz...

Thanks in Advance... Ranger..

The 20 % is a small amount but it's still going to cause the detination issue.
Usually damages head gaskets first ,but we have seen piston damage where the detination has destroyed the piston skirt itself. As stated earlier the crank is next to go. Sorry Buddy but not with my money.:burnout

Shot down in a ball of FLAMES!!!

Weeeeelllll,,,,

I guess I am going to put that one to DEAD rest.... Courtesy of BD Diesel Performance... THANKS TO HARALD, good on ya Buddy! (That means thanks is Australia...) No one else has been able to pinpoint the problem with LPG on engineering of the motors... THIS SOUNDS LIKE IT!!!

Unless anybody else has any input that goes against the research of BD Performance...

And we will wait to hear from Ford Guru Marc on the water/meth and what that means...

Thanks Guys, and on the behalf of Bushtracker and Fords in Oz.....

Regards from the Lone Ranger...

Water/Meth injection is really quite simple. You place a couple jets in the intake tube between the intercooler and intake manifold (closer to the manifold the better), give it a tank and a pump to squirt it out. I don't know to much first hand stuff on it in a PSD but on a Cummins you can start using it at about 10-20 lbs. of boost (depending on the controller you have), anything lower and it drowns out the igntion of the fuel. It is like any other "drug" to much is a bad thing, a 50/50 mix is the most recommended and most guys run 60/40 or 70/30 water to meth mix.
