xf_turbo Member 45 Member For: 17y 9m 1d Gender: Male Location: Adelaide Posted 25/06/07 08:49 AM Share Posted 25/06/07 08:49 AM Hmmm. I had a VL Turbo for 450.000 kays running Dual Fuel. Lots of hassles with backfires 'till I got the right HT leads. Must be 'Blow Through' with an intercooler. 9Or ot self destructs.Mine had +2psi and 3" pipe with no rear muffler. Other wise stock Manual Berlina Wagon (Family sports car )Pros: More low down and mid range torque.Oil stayed crystal green cleanCost a lot less to fuel upEngine did 450,000 with bottom end still greatCons: Ran out of breath in top end (tuning issue?)Had 3 new heads.Had to fill with fuel more often: 8-10km/litre on ULP, 5-7 LPG.Unless LPG was less than 1/2 petrol price it was line ball for cost advantage.Bloody backfires!! Blew up a lot of air mass meters and filter boxes. (used to buy AFM in bulk at its worst)Not as much load space with spare in the back.I would not try it again unless it was dedicated gas and proven liquid injection.I have been trying to follow the progress of commercial liquid injection systems for years now but it seens there is almost NO progress. Liquiphase made a lot of good noise then disappeared. I recon the Ford factory would have used Liquid injection if they could have made it work for their dedicated Taxis. Nobody seems to be able to tell me what the overwhelming problem is but there obviously is one.A mob in Melbourne was developing a new type of injector but they have gone silent as well.There is a guy in sydney who was developing gaseous injection but that seems to have run into problems too.Liquid injection can have a HUGE cooling effect on the inlet charge. That is probably its killer advantage, but may be its major problem as well.I hear they have cars on Liquid injection in Europe (Holland) and trucks (F250type utes etc. in USA, but not much detail is available.As for the octane level, it does indeed vary a lot with the Butane %. Pure Propane is very high (110?) but Auto gas in Aust is not much more than Optimax. (according to the fuel companies) Obviously, if you build an engine to take advantage of it you can do big things with Propane.I spend the same or slightly more per km on fuel now withthe 'XR6T' than I used to with the VL. Comparing a converter mixer sytem with modern electronic fuel injection is chalk and cheese. LPG technology is light-years behind and there is no sign of it catching up.I am sure some very clever tuners/engine builders out there can do some amazing things with current (stone age) LPG technology, but I am over it! The reason the VL's bottom end was still good is because those engines had a fantastic pretty much bullit proof bottom end! And going through a few heads is standard for a VL Link to comment Share on other sites More sharing options...

RAPHOON Donating Members 1,776 Member For: 21y 4m 14d Posted 25/06/07 11:05 PM Share Posted 25/06/07 11:05 PM The new gas setups in Europe (I believe at least some of these are now available in OZ) are getting better performance out of gas power than fuel.The RON rating has always been there but now the conversion from liquid to vapour and the delivery via individual injectors has allowed this to be exploited.I know there's at least 1 guy in Brisbane installing the new technology gas conversions.

He seems pleased as punch with it.Ive done a bit of research lately and it seems many of these systems will switch to petrol under heavy load being the only catch....Otherwise marginally worse economy (in terms of l/100), starting on petrol to avoid startup issues, and improved grunt. Not a bad result. Pricey though at 4K+ per install (of course less rebate sounds better but still costy). Link to comment Share on other sites More sharing options...
