1976  shortwheelbase van.
has a red 202
4 speed Australian g/box.
borgwarner highway diff.
std 186 carby n manifold.
electric dizzy
extractors and good cond, quiet exhurst.
twin batteries. boat isolater switch fitted to switch from 1 batt to 2 or both at same time. or full off. solar trickle charge system fitted.
std bodyshape.
 just carry spare points dissy, leads,new high spark coil, new spare water pump n gasket. heater and rad hoses,10ltrcar fridge,jack, toolkit holding all nessessary tools 4 roadside repairs within reason. spare under back, decked out inside
14in sunraysiers, new front tyres.back 70% all hancooks.
no roofracks at present, (so no wind drag),
getting LPG conversion in march 2009, will b dual fuel.
so exess weight isnt a real issue.

( will edit this all tomorow with diff ratio, and fuel economy of how many kms per litrein present state.. will do a drip feed 1 litre system and measure kms.)
then change carby,manifold and post difference)(just give me a few days, lol, weeks maybe, )
.no oil leaks at all, ask ben,dry as a desert under whole van.
new clutch p/plate. rase,
, not sure of ratio, will look tomorow
not sure of kms on motor,
, old leads, havnt looked at spark plugs for about a year.
 has a crappy 186 carby, can tell from inlet manifold,
i drive prietty calmly as it still has drum front brakes, always leave 4 car distance in front at 60 kms, 10 car distance at 100 kms an hr. im in no major hurry.
might do a HQ disk conversion soon,
have a fully recond red 202
carby and new inlet maniflod just waiting to go on.
might change it over 2 a auto soon 2 as im over changing gears and clutches, gettin lazy in my old age, plus it will be easyier on my left leg n arm.
100 dam gearchanges 2 shitme, i mean 2 sydney  n back.
auto just click it into drive and steer n use the brakes, less stress.

gday! great topic as yous know im always on about fuel economy!
swb
202 red. head done for straight gas
straight gas! 2 tanks 140 litre cap approx.
reco trimatic
extractors
elect dizzy
holden banjo 3.08
14in widened wheels 7/215 front 8/235 rear (wanting to go 15in if had the money)
sits at 2700rpm @100 (those with tachos please add as im very interested in others rpms!)
fully loaded i was getting 4.5kms/litre 5 if i really cruised it. many variables including the weather and road conditions.. hilly , headwind etc.
played with the gas mixtures heaps, running it at max power cut about 70kms off my range but was great up hills!
john abbott any idea what yours is in kms/litre for us young uns! and with the 2.78 how does it take off with a load?
marky do you have a tacho i wonder what your rpms are at 100 with the 4 speed coz with my 50 litre tank i get 250 max on gas so your getting 130kms more on petrol! quite a difference!
strez yours sounds quite economical too! if i convert to litres/100km its around 20...
ben does yours run fine on both fuels? im thinking of going back to duel fuel. people say you have to compromise with the tuning but im not sure it matters with our old holden motors. i had a hr ute that ran perfect on both.
jock your economy is like mine! so it will be interesting to see how it changes with the new diff.. poor thing must be screamin at 100!
marty your van is almost exact like mine besides the gearbox so im interested in your future results, i agree with changin gears im glad mine was auto on our big trip but i would love a celica box! had one in my hr and it ripped!
take it easy!

hey there does anyone know how to work out how many revs you should be doing at 100 with direct drive with whatever diff youve got?

ben

[Marishka]

yeah, the revs x the diff ratio  devided by  the litre = thethingybob

Well I can't "MODIFY" my own post to include that my van is running a 3 speed Trimatic Gearbox so I will have to add this post as a reply.

[Marishka]

ok here,s the test equipment i knocked together.


the 2 bottles are 600ml. 1 full and 400ml in other = 1litre

i did the test twice, starting off and reaching 80kms p/h on a straight level road. not slowing down at all......
it used exactly the same amount both times .
i got exactly 6kms per 1 litre, that sucks, i was at least hopeing for 50 kms per litre. hahahahaha,
will do the exact same test again when i change to the recond 202 carby and new manifold.
