I'm just wondering what the CoD of the Brumby is. The 1st gen sedan's CoD is around 0.337, I think with the tarp on the back the brumby could be similar.


Also: What's the curb weight, frontal area, all that stuff? I've just looked in the tech manual, but there doesn't seem to be anything.

thanks folks

Curb weight will be in a brochure somewhere.
I weighted my stock-as-a-rock 92 Brumby before I started pulling it apart. It was a neat 1 tonne with replacement alloy bar and towbar on.
Also recently weighed my '90 Brumby with EA82T, constant 5-speed, rear discs, bullbar, towbar, rear step, 2" lift, rear coils, 14" alloys with heavy 8 ply tyres and only came to 1200kgs.

Ah thankyew, that's a good start. 1200kg should work as a good estimate for the time being. I suppose the CoD would be roughly the same as the leone, as long as it had the tarp on the back, so I'll just have to find that.

The 1981 sales catalogue states the MY sedan has a drag coeffcient of 0.45 (and it goes on to say that it is better than most four cylinder cars on the market!).

I doubt a Brumby will be any better, the short roof would not do much for drag.

Oh yeah, the same catalogue lists the Brumby's weight as 975kg.

Do I sense an Electric conversion coming on??

haha yes. Just gathering info now, as the missus insists we buy a house before anything else. And I need a garage to work in anyway! :P

I would like to do this myself. Especially because I am 90% dependant on solar energy (the other 10% is still diesel), I can recharge the cars batteries without using coal burnt power.

I read the kiwiev thread. Very interesting and he makes it all sound pretty easy. Didn't realise all the tech info and stores were allready catering for this market. So much to do so little time.....and I still want to build the worlds first diesel Brumby as well.

I wonder if those new diesel engines Subaru are making for the new models would fit in the brumby? Surely an adapter plate wouldn't take long to come on the market.

They fit in the same space an EJ does.
Adapter plate? It would pay to use the transmission designed for the engine.

There's a formula to calculate drag coefficient :



Taken form here : https://en.wikipedia.org/wiki/Drag_coefficient

= drag coefficient
= drag force
= mass density of the fluid
= flow speed of the object relative to the fluid
= reference area

& to in order to calculate will need to know the following :

- The 'Frontal Area' of a Brumby = ( TBA )
- Drag force / variables of air flow

More info to be had here : https://en.wikipedia.org/wiki/Automobil ... oefficient

Notes: The reference area is the projected frontal area of the vehicle -
Have'nt worked out what all the variales are yet, but will come back & update when I can get something usefull.

Cheers, Bantum ...
