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.
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..Quote:

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 [emoji13]
