Fuel consumption / economy report

[big_fletch]

Sorry my bad, edited that last post for not checking it haha, Was actually 52ltrs. So averaged 11.4 the whole trip

[nicksamaniac]

Gq wagon, 6" lift 35s, tube winch bar, 12k lbs winch, sliders,
Rb30det @ 300 wheel hp through 4.88:1 diffs,
regardless of hwy or town, 17.5l/100km.

Going bigger turbo soon to create more vacume at cruise speed to reduce fuel usage.
current setup is too small and I'm using hp to push exhaust through it

I'll be doing my around town figures soon ,
as I'm changing a few things so it will a before and after

My RB30 GQ is getting about 17.5 litres per hundred too, but it ain't got anywhere near 300 hp...

When I first got it it was totally stock, it used about 13 litres per hundred or thereabouts. I've added a few things like rhino roof rack 2 inch lift, snorkel, second battery, fridge etc, so a bit more weight and wind resistance I suppose.

Off-road on sand with the tyres down at Yeagarup over the Easter break it was more like 29 litres per hundred! I need to repair and fit up my aux tank next to have something approaching range.

I've got a 1990 RB30 carby. 31s, 2inch lift, roof racks, long range tank.
City/Town: Its not too bad - the guage drops fairly quickly EVEN though I drive like there's an egg under my accelerator.... but here's the good part:

Highway: 14-15l/100km consistently!!! Cruise about 2700rpm on the flat at 105km/hr, with foot to the floor up big hills etc.

Sand: Around 25-28l/100km but its worth it for the sweet power of the RB on the dunes. basically unstoppable unless you run out of petrol

Maybe a useful info: with 145lt "Long Ranger" tank, I've documented all my fill ups and on the fuel guage (petrol remaining): Full - (who knows?!)ltrs, 3/4 - 90ltrs, 1/2 - 70ltrs, 1/4 - 50 ltrs, Empty - 30ltrs

I have just fitted a 3/4 roof rack ,so that must throw the figures out a bit.

[rusty_nail]

just went through a tank and thought i would do some calculations. i did 595Kms and filled the tank with 81 litres which equates to 13.61L/100Kms. pretty damm happy with that! thats wayyy better than before the engine rebuild and even better than the old petrol clunkers i had lol

My RB30 got 13.4 ltr/100km highway driving after fitting the headers, removing the heater grid under the carby, and disabling the pre-heat flap. Very happy with that.

Shit yea. Very good..
Your on par with the td42..

I was thinking the fuel usage jumped when I put the chip on it but I just realised I put it on the same day the 33s went on so that might be the reason for the fuel increase ? I think standard tyres are 31" ? I remember they were road tyres & looked like they were off a commodore
