Gid'ay all, It would be great if someone could help, My GQ TD42 suffers from lack of legs in some of the comp's we do here. It is Turbo'd with a Safari kit and is fitted with the 3" mandrel bent exhaust. Some of the other competition trucks here are bolting on a LPG injection unit which is injected on demand like nitrox in a petrol engine. Gains of 25% in short bursts are achievable but this always comes at some expense. Have any of the readers used this system?, any help would be appreciated.

cheers.

I haven't used or even seen this system on a vehicle, however I've read this companys advertising material. On paper this technology looks promising. They claim up to 25% power increase by replacing 20-25% of diesel used with 15%-20% LPG. This is an Australian developed technology and the company is called Global Fuel Solutions. Contact in NSW is David Medina 02 9211 0078.

Just by a nitrous kit and fit it, fix your lack of power.

http://www.transport.nsw.gov.au/ministerial-inquiry/Global-Fuel-Solutions.pdf

The last page of the above pdf has some technical information.

These two are uk sites also with some technical info. I think these systems are different to the OZ one (not as sopisticated) but I haven't had time to read all the info.

Why not just go with a 350 chev conversion, would be better.

sell the TD and Safari seperate to recover costs..

There was on LPG inject that went poo and blew holes in 2 pistons on a GQ.. cost him a new block and pistons and crank etc..

looked into those systems some time ago and they were designed to run with a slightly leaner diesel ratio. adding the LPG to a full flow diesel ratio could end up giving you the same headaches as regular overfueling which over extended periods can be desastrous so I suggest you do your homework very well because diesel engines don't come cheap.
