VDJ79 Dual cab help

Hotfishez,
the only mod that will get you 11.9/100 is the lifting of the right foot.
I have got down to 12 on mine when I first got it
empty tray, running at max 100 km on freeway travel.
now with the canopy on back and always heavily loaded , running 285's it averages 15-15.5.
I try to limit revs to 2500 when cruising.
the vehicles have the aerodymanics of a brick on the highwayand thats where fuel use is worst.
surprisingly in a recent drive from Mungerannie to Poeppels corner via the Warburton /K1 it returned 7.9 km per litre(12.5/100) when loaded to Max but we were driving in fuel conservation mode.

cheers
Howard

My consumption figures are similar to Howard's and I run fully laden with a gullwing canopy
To give you a comparison the last trip I did of about 6000k I was averaging 10 to 15% more fuel use than a similarly configured dual cab diesel Hilux, this was a mixture of highway and offroad use, my vehicle would of been heavier than his.

Hi, I have the wagon and average 12 - 13 without any real change when fully loaded for a trip (not towing).
My daily drive to work includes lots (lots) of heavy traffic too.

When new, my 2008 Troopy came with skinnies – on tests on bitumen, and a light foot on the pedal 11.9 was achievable.
When I changed over to the wider, lower pressure, 285/75 tyres fuel consumption rose noticeably.
Wouldn’t tow in 5th - tests, towing a 3 tonne caravan on bitumen showed there was no measurable difference in fuel consumption between 4th and 5th

Not sure Robin

But isn't there a legality/insurance/road worthiness issue with wheel spacers??

My understanding (limited thought it may be) is that they're fine as long as you don't use them on road.

Wheel spacers are definately illegal for on road use

Marginally Illegal Rosco - but Hotfish has stated he wants 285/75/16 tyres which are probably illegal on that car.


(Degrees of illegally is an interesting concept - in practise you could probably win with properly done spacers as they make the car safer - as we still have some common law rights left).

As an aside to the spacer debate, I totally agree with Robin's sentiment in respect to widening the stance of the rear wheels to match the front.

I have used generic steel spacers with a drastic result. I then had custom 40mm spacers made from Billet aluminium from Galpro Engineering in Adelaide. The 40mm allowed at least 15mm of the axle hub to act as a spigot for the wheels. Being custom made, the tolerances and fit were a damn site better than the steel units. No problems with the aluminium but having lost a wheel, I was always nervous due to the conditions I subject the vehicle too on one of my trips.

Just before leaving on this year's expedition I had Multidrive Technologies in Geelong widen the rear diff housing and make me custom axles. They also laminated and strengthened the diff housing all the way to and around the diff pumpkin. Bloody magnificent job, the stances of both axles now match perfectly and it's fully engineered, certified and no insurance/rego hassles. The diff housing has also been strengthened as an added bonus. It kicks serious butt in the sand now!

Darryl is the bloke to talk to.

Thanks for the info Mick, and I have ordered the Fuel Manager from Terrain Tamer...

Spacers or not - It’s a personal choice.
Having driven in groups of 4WDs, mainly in sand, I have never been at disadvantage by not having spacers. The main difference I have encountered is a person’s sand driving ability (excluding differences such as the engines torque at low revs, ground clearance, or its wheel diameter and width)

Hi there I am interested to know how you have found the KM2's as i need to replace my tyres in the next month
Thanks
