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.

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.
