gas systems for diesel engines

I recently read a question (and answers) posted on 18th October regarding LPG systems for diesel engines and I would like to inform anyone interested in this type of modification that myself and a friend of mine have imported a kit from the states using normal BBQ gas or Propane (bottled gas) and fitted to an 84 330HP V8 Mercedes Benz Truck. The system relies on the turbo boost pressure to proportionately let gas or I should say vapour, into the inlet manifold with no computer or mixer to regulate it. It operates entirely on boost pressure so non turbo engines cannot use this system! and let me tell you we had it dyno tested in dandenong VIC and the results were unbelievable. The engine was a standard 330Hp (@ flywheel)factory. when the gas was on it had 400hp AT THE REAR WHEELS!!! on the minimum economy setting. Now this kit was initially designed for SUV trucks in the US like the Diesel Chev, Ford and Dodge engines but has now gone thru to the heavy truck sector as well. We are about to receive another 3 kits one for my 360HP Scania Rigid and my Western Star with a 600HP CAT and another friends 300HP International S-Line. Pending the results of this, I intend to put one on My 99 2.8 Patrol but with the particular company installing kits into 170 vehicles a week, the results should speak for themselves. Now early in the new year we plan to take up the distribution rights for Australasia offering these kits to truck and 4WD owners alike. If there is interest shown from this i would be happy to explain the ins and outs and everything else. Lastly, this Benz in Question was getting around 2.1-2.2 kms per litre running to Sydney from Melbourne with around 20Ton on. With the gas kit it is consistantly getting 3kms per litre using a 9kg bottle there and back. The Propane acts as a "catalyst" when combined with diesel fuel. When propane is added to diesel fuel, almost 100% of the fuel is burned (as opposed to approximately 75% without propane injection)More soon!!!
