A.P.E

Some misconceptions about LPG use should be expected because many opinions exist without measurement and proof but here is what I can tell you with the experience we have so far on Turbo XR6 and Territory turbo. I will not go into non turbo cars here because although we do so many, such cars are just low output variants that do not suffer the same issues as forced induction. Our BA XR6T was the first to be done in Australia and I still use it as a daily driver with no complaints. We have tuned it to 353rwkw on our Mainline Dynolog dyno on petrol with the use of MGA Zavoli multipoint sequential vapor injection. The tank is 55L useable behind rear seat so that added weight is kept between axles whilst offering the extra 2 litres or so storage that the donut does not offer. Such considerations were less important than having no spare or worse still, a loose spare in the boot just in case of a serious accident. (Personal experience keeps safety top of mind because the emotional cost of losing a loved one to a car accident is something no one should endure) Melbourne to Adelaide RETURN cost almost $100 fuel when lpg was 56 cpl so the savings are well worth the effort. City cycle is typically 330 to 380km range for the 55 litres depending on driving style and country has been consistently around 440kms for 55L System sequentially shifts from lpg to petrol when exceeding a programmable rpm and load point simultaneously so to cruise on lpg then nail it past a truck will have it switching for you before going back to lpg when load and or rpm is dropped below programmed amounts. This works well to say the least. It is seamless and ensures low combustion temperatures. (Remember that lpg offers approx 30% higher demand on ignition systems and combustion temperatures than petrol) It may also have a higher octane but a lower calorific value means less bang for the same quantity. You may not wish to hear this with all of the bs about more power through higher octane but that is how it is with any vapor system. The MGA system uses injectors that can be mounted individually instead of a fixed rail so much more flexible regarding how stealthy the conversion can be. The injectors are very quiet compared with almost all others. They also are serviceable so if you are an unlucky one to have contaminated lpg, then at least you have an affordable means of repair instead of an alarming cost for new injectors as is necessary on almost every other option out there. (Filters will not save you from that issue) Territory turbo and falcon have been a common conversion for us for the last 4 years or more and we have enjoyed success for all of our clients with these vehicles. This means no come backs so we are happy and our clients are happy. Sedans are typically between $4,500 - $5k for conversions including dyno time etc whereas Territory is more costly due to custom twin tank and spare wheel bracket, cover etc so not a cheap option in either vehicle. Spare wheel on the roof also risky to others in an accident so not advised. Keep your extra seats if you need them and stay on petrol or consider an engineered bracket if you wish to keep those seats in use. Don't take the risks. LIQUID INJECTION The obvious advantages should be a chilling effect of the air charge as it enters the combustion chamber due to lpg changing state from liquid to vapor at this point. I would expect improved power and possibly slightly improved efficiency. Stability of this system is still one to monitor over time because they are quite new here in Australia. A pump in the tank is something to expect requiring maintenance in time due to the dry fuel and the simple fact that any pump has a service life. They claim 340rwkw out of these systems on XR6T so that is pretty good for gas supply. Only issue may be that if you find the limit, these systems DO NOT auto change to petrol. My advice may be to push the button if you are going to nail another XR6T or simply leave it on gas for the LS1 challengers. Cost for these systems would be higher if you consider the pump but lower due to no lpg converter. End result seems to be just under $5k so quite comparable really. Time will tell with the liquid systems just as it has with many vapor systems but early thoughts are that it should be advantageous for many reasons. We are engine management and mapping specialists so accurate calibration and diagnosis of such things is a daily task for us with petrol and lpg. We will be attending the upcoming installer training session in Adelaide before fitting these conversions but remain optimistic of the outcome. I will keep you posted with pics etc if anyone found the above informative. Brett Adelaide Performance Engineers (A division of Graham West Workshops Pty Ltd)

See previous reply regarding phoning the office for quotes. (I am not the quote man and could not give accurate information on costs) The tanks go under the back, where the spare wheel would normally live, so this is relocated into the rhs luggage area on a custom bracket. The $2k rebate would apply to privately registered vehicles, so long as you have not claimed within the last (3 or 5 years I believe)

The system is Zavoli and we enjoy manufacturer support for it. (They send techs over to see what we are achieving and love our graphs and data of cars we have done) Costs for the XR6T are approx $4.5k, so the Terri is more due to the additional cost of custom twin lpg tank, spare wheel bracket inside wagon, then the exhaust modifications to clear the lpg tank. I am not sure of the total cost because this is done via the office. (I concentrate on tuning and tech support, but I leave the quotes to those who cannot do tech and tuning) If you need more info on this, just phone us on 08 8277 5688, then Lynette or other staff will be able to advise.

Hi Nick Thanks for that. When did you get out??

The Terri was actually quite a surprise with its AWD system, as I actually expected more loss than we saw. The system is not really designed as a Patrol or Cruiser contender for off road, rather than an AWD for on road manner Dirt road manner wet roads and safety etc, not really a hard core off roader robust truck. Generally most do not need the really tuff off roaders so Ford really hit a great result with this vehicle. For those who do, stick with the hard core off roaders. (My opinion anyway). Either way, just consider the stated flywheel kw and deduct the 187 awkw we saw standard. this should give you a rough idea of driveline losses. Ignore the rumours of using a percentage for driveline loss calculation, as this simply does not work and the best way to determine flywheel kw accurately is on an engine dyno. Vapour rings as was on your VT simply reduce the diameter of the throttle body, hence less power on petrol and LPG than would otherwise be available. Other issue is an intake manifold full of fuel / air mix ready to burn, so any issue at all causes a serious induction backfire with associated damage. Bad on the VT, but catastrophic on an intercooled turbo engine!! The system is VAPOUR and is MULTIPOINT / SEQUENTIAL INJECTION Injectors are good for approx 37kw per cylinder, so higher than this has us programming an auto changeover from LPG to PETROL, that happens sequentially rather than all cylinders at once. Cruising along or even under load, LPG functions. Nail it to pass a B double etc and it will auto tranisition to petrol, then auto back to LPG once you are off it again. Totally seamless changeover. I love having previous LPG clients like your VT system, drive at full throttle and change fuels as often as they can. You can see them tentatively pulsing the button, waiting for an induction backfire, but this system does not fill the manifold or have restrictions to the induction system. Great power and no backfiring.

The results on the turbo territory showed a typical requirement to raise initial boost for added torque but to reduce it as the revs increased to ensure safe injection duty cycle. Result was a fantastic vehicle that leaves my 350 rwkw XR6T behind on wet roads, because it can simply be nailed and it goes without any fuss. EVEN IN CORNERS, just nail it and the stability system keeps it together and off you go. Although it does this so safely, you really have a drivers feel from the car due to the dynamics and rear torque bias. The dual fuel multipoint sequential LPG injection system allows the best of all of this whilst making the car cheap on fuel to rival a Corrolla's fuel costs!!!! Great Aussie production, because where else in the world could you create a total package such as this vehicle? Check out the power graph showing torque split during power ramp.

Adelaide Performance Engineers have the MOST ADVANCED CHASSIS DYNO in South Australia that offers mapping and data logging abilities beyond any other. It operates within a CUSTOM BUILT DYNO CELL to MAINTAIN CONSISTENT TEMPERATURE CONTROL and ALL EDITING has ALWAYS included the latest KNOCK DETECTION EQUIPMENT as should always have been included in any mapping session worth it’s weight. What other dyno can log data straight from the cars computer during a power run? Imagine the massive array of valuable tuning data that can be gained by this, which is only one of the advanced features our dyno has. Our primary concern is ensuring our clients continue to receive THE MOST REFINED MAPPING FILES AVAILABLE and we remain committed to achieving this by ensuring our equipment is not just the most up to date in Adelaide, but in Australia. We are technicians, not sales people, so our intentions are FOR OUR CLIENTS. Just ask any of them.
