I've been keeping a close tab on my fuel usage recently which is in the table below.

Reason i've done this is because I plan to get a PowerFC and plan to do some comparisons.

I have a R33 gtst with cat back exhaust, and an air filter. Next time I fill up i'll have a full exhaust + highflow cat + no exhaust leak. If anyone is interested I can continue posting updates and will let you know how the powerFC compares when I eventually get one.

Well , I was getting 400+kms per tank sydney driving (includes 40kms of 100km/h driving per day) on my stock + zorst R33 (150rwkw)

After mods (now 220rwkw on low boost, (14PSI) ) I can just get 300kms to a tank and thats driving like a grandma mostly, with a few squirts here and there.

Hmmm and I do 100 kms per day round trip for 5 days per week. Add weekends and thats approx 2 tanks per week. @ 1.00 per litre thats over $100 per week just in petrol - Holy Fark !!

I drove to Yarrawonga for new years (600km round trip). I filled up at the servo accross the road from my house before I left and the fuel light came on when I returned to the outskirts of Melb. About 550+km to the tank sitting on about 120km/h most of the way. Not bad me thinks!

my 2c. filled up full 2 days b4 the vic cruise at albert park pits. about 55 - 60L. got 480k's out of it before i filled up. my best record yet. and that was full of twisties, traffic light drags and top speed runs too. :D so it wasnt completely granny driving... :D

i get my best economy when i go on cruises believe it or not. Mainly cause my normal driving is shorter trips. Only had my 34 for about 6 weeks but have recorded 385 kms from 36 litres - highway driving only.

The tank is 65 litres. Reviews i have read say that it is a little more economical than the 33, i have seen figures of 9.4 l / 100 kms quoted.

What I don't understand is I get around 470km's to a tank driving around adelaide with 10km trips to work then 10km's back.

I give it quite a bit and often have runs through to third flat stick.

When I take it through the hills with giving it a hard time the worse i have got is 430km's.

Arn't the R33's meant to be better than the R32's on juice.

This is running 16psi also.

Yeah I dunno what the story is - as I've said, no matter how much I get up it, it's unusual not to get 450-500km out of the tank before the light comes on... some of you guys must pull the bung out of the fuel tank or something :D

Just wondering if Auto and Manual could make difference as acceleration tendincies would change.

I have a manual turbl line and i try to drive conservitively but still find myself in front of the traffic after accelerating from the lights!

Where as with my old commodore it had power but was an auto and had a tendincy to 'cruise' and saved fuel...

what do you all think?

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
