Dual Fuel Edited Turbo Territory

[A.P.E]

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.

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 some graphs and we will add more as the car progresses further in future.

Where's the tank located in the TT's and what cost is involved in converting to dual fuel?

The gas smooth's out the curve nicely.

well done brett!

Well done guys, great results. For the ignorant on the forum (like me), I assume is that running purely on LPG and not LPG and petrol at the same time? And with the note that it is LPG injection, does that mean you are running LPG in liquid form right up to a set of special LPG injectors? I am only familiar with a LPG system I had on a VT Late model camira about five years ago where the LPG as a gas fed into a mixer ring on the induction piping.

.... and one more thing to answer my curiosity, pulling 225kw at the wheels, on an AWD system, what would that roughly equate to at the flywheel?

~300fwkW.

It's not a % loss as many people say, it's fixed based on drive train "size" no matter what power you are producing.

XR6T would have ~50kW loss through drive train, add further 10-15% for AWD.

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.

well done brett!

Hi Nick

Thanks for that.

When did you get out??

[tab]

Sounds exciting!

How many $'s are you looking at to install this setup?

[God666]

Hi Nick

Thanks for that.

When did you get out??

Pentridge has been closed for some years so most of his hair has grown back now, and he is almost over that 'man love' thing that he had going.

.... and thanks for the feedback Brett.

[ZAP]

Brett what would be a rough indication of the costs ?

Where do the tanks go for the LPG ?

Would this qualify for the government rebate ?
