don't think its got anything to do with which series you got... I get on average 390-450 per tank.

I also did Adelaide to Perth when I first bought the car and the best it did was 520 with an eighth of a tank lef and doing 120kms/ph... and I'm guessing that was on stock boost as some twit had disconnected the EBC.

I have

SAFCII

Greddy EBC

Metal Cat

3" cat back

always run on BP 98 Ultimate

toyo tyres

running on 10psi

And I have fun sometimes. its hard to stay off boost. :laugh:

I switched from bp ultimate to shell vpower a few months ago and noticed my car ran richer, and not as smooth. It was ok at first but eventually I figured my car just didn't run as well as with bp. So I've since switched back to bp ultimate and couldn't be happier. I basically just wanted the savings from the fuel dockets to get 4c a litre off with shell, but noticed that bp was often about 2c a litre cheaper anyway where I live. I'm not a fan of the whole fuel discounts thing - it just means they bump up their prices to accommodate it, and therefore rip off those that dont have dockets on hand...

In my experience bp gives better performance and just makes the car run smoother and generally better all-round.

Fuel economy was about the same on both, couldn't really pick any difference there.

I had my car tuned on bp ultimate - not sure if that would make a difference...it could have affected timing I guess, which at that stage was not advanced at all.

Yea me too. When i first got the car i tried 3 different fuel. Bp, shell and Mobil. I found mobil to be the best of all. It gave most power amongst the 3. My car was tuned on mobil98 . Ben from Rcepace gave me the option of using wither mobil or Bp and i chosed Mobil.After the tune i ran with boost 98 and i cant pick the difference other than the price.

With boost 98 with a/c pn 80% of the time mixed in city driving and HWY (30%-70%) im getting about 430-450km/tank). The car after tune is pumping out 236kw@wheels. So its not bad for the fuel consumption.

i found with every car ive had that making sure ur engine is running as good as possible is the key to fuel economy. always check ur coils and spark plugs r in good order, ur tune is spot on and always use a quality filters (oil,air and fuel) always replacing them at required intervals (or a little sooner).

oh and dont carry around crap for no reason. always remember to keep weight as low as possible. depending on how bigger concern economy is u may want to stop using the drive thru window, u'll save fuel and wont get fat from junk food :)

Im using baldwon filters and i think repcos fuel filter. As for air filter im suing K&n drop in replacement filters which runs great with the car. Oil wise im using Castrol cos Ben from racpace wanted to use it. I personally like using Mobil synthetic. Im currently using Castrol 10w-70.

10W70 holy molasses batman !

yeah we are definately running thinner than that .. but I will check for sure.

now.. can someome educate me as to WHY the fuel filter could be causing poor consumption?

I am not saying that its not a valid possiblity but just want to know the reasoning behind it.

yeah I too am debating the S2 myth that it gets better economy.

we have an s2 and can just get 400k till the fill light comes on

we ( stagea owners ) might need to get a bit more methodical about what fix made what fuel econ difference. ( ie start logging it all in this thread etc )

also doesnt really seem like anyone in here has confirmed the working operation of their o2 sensors.

I am close to finally getting off my ass and getting my consult to see if it can read the operation of the o2 sensor while moving etc.

S2 here as well and am only getting 400kms before the light goes up which is around 60L (15L/100km). I would be far happier with 450kms (13.5L/100km) before light if possible. Running hi flow panel filter with TT mbc @ 10psi as the only mods. That's with Boost98 too.

I replaced the O2 sensor with the NGK/NTK one and when the car was in the workshop the other day they tested the O2 levels (or was it CO2?) to check air fuel mixture by sticking a rod into the exhaust connected to a handheld electrical meter thingy while driving around and all the readings were fine. Does that mean the O2 sensor is alright?

Been quoted $500 and for a custom 3" mild steel catback exhaust, very tempting if it guarantees drop of 1-2L/100kms.

Well.. i now know the car runs exactly 419.5kms on a full tank of Boost98... the missus couldn't start it this evening as it had run out of petrol. It equates to 15-16L/100kms which in my books is still disgracefull seeing she uses the car 90% of the time and it'd be lucky to see more then 2psi. That was with a bottle of Nulon Injector cleaner in it too.

yeah thats pretty damned poor hey?

One thing I cant seem to get out of anyone are a few things

how many people can categorically say they have a working o2 sensor ?

Ie .. its been checked by reading fluctiating values from the sensor etc.

Another thing I want to know is what is the supposed fuel economy of the stagea

when it came out of the factory? Maybe it was woeful from the very begining and

we are just chasing our tails?

That's something that would be good to find out. Anyone here know the Stagea factory mileage?

420-460 repeatedable around town/short freeway/hills

10.5L/100 has been done on the GOR/Otways/FWY

worse economey when i am just using it for general running around coz its all short trips with speed humps/roundabouts.

i've never seen any proof that a fuel filter can effect fuel economy. but its cheap insurance against leaning ur engine out.

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      By CRSKmD · Posted

      My 6 Point FIA harness have arrived (kinda). There was a mix up from the supplier and I ended up with 3" set rather than the 2" set. I contacted them and their customer service was top notch. It is being resolved and 2" ones will be on their way to be soon but in the mean time I was able to at least mock them up in the car to see the vibes. Need to organise some fixed back seats so i can actually use them as a 6 point. I am leaning towards the Velo Podium II XLs as I like the look of the bolstering compared to the GP90 XL or GPT2. The side and thigh bolstering on the GP90/GPT feels less that my existing Bride Digo R recliner. Velo Podium II XL Velo GP90 XL Velo GPT2

      Yea I know the wiring would be fine just want to use I got. This was my first built engine and it blowing got me beat down just want to have it running right again but hopefully I can find a non vct head so I don’t have to do any of this lol.

      R32 Gtst - Track Car

      By bcozican · Posted

      Recently did the Perth Festival of Speed - and basically what we thought might be an average event turned out to be absolutely awesome they bought Mad Mike and Xtreme over and was good to see Perth get, support and produce something so good - 24,000 people in two days      It was nice to have it close to home for once yet have my whole crew there to run the car properly     Xtreme got the tin top laps record with 51.57    I hadnt done a hot lap on the home track for 20 months and finally everything clicked and dropped 4 secs off PB and did a 53.29 which is 3rd fastest tin top ever around that track. only 1.3 tenths behind 2nd so should eat that up soon... can I get Xtremes time - its not out of the question   Alll the blaa blaa's in the world but if I can replicate even close to that situation on other tracks will be able to make an impact     We got asked to do the hill climb to put on a show which in reality is just using some chicanes and the short track at barbs but good fun... launch control was put in and won the Pro class in that also.     Car needs some attention after being on it around Australia for last few months moreso the carbon underbody work and just a run through and clean up everything else seems to have held up good enough. Would like ,to take some weight out but that requires alot of effort 😁   Also waiting on new rules for WTAC and have some decisions to be made there and prob some minor modifications to suit pending class changes. Will see...   Divided on whether to go hard for one more year or chill out re: events this coming year prob more on the go hard and see if I can get improvements in times. If I didnt have so travel so far it would be less of an issue but I do so hmmm...   Also because build thread - gone to flappy paddles and a gearing change with a drop gear. It was becoming apparent that there were situations where I really needed to be hanging onto the wheel with both hands yet had to change gears and was getting a little sketchy and / or I just didnt change gears and delt with it and also 5th gear at 10,000 rpm is 290 kmph so I havent been using 6th as did 282 at WTAC and 274 in Perth drop gear will change to 6th being 300 at 10,000 rpm should also get a touch more acceleration speed

      No, not really. Except that there are newer, better cam options that don't date back to the 90s. I was under the impression that you couldn't use VCT with them, which is why I said to get rid of them. If you can't/won't use VCT because of what you listed above, that's another matter. Although I would have said the wiring aspect of it was something that you should just suck up and do, as it isn't hard. Getting an actuator for the cam gear will possibly be expensive. I still say VCT is for the win. There's a reason HKS makes money selling it for 26s.

      Is there something wrong with using tomei?  I’ve heard the tomei usa are fake parts. Reason why I don’t want to make vct work is one gotta make a plug for the solenoid get the vct cam gear. I rather just use the stuff I already have. I made 450 on 17psi full boost at 4K. I’m satisfied with that it’s a street car and sometimes hit the track for drift. If I’m really wanting to decrease the lag I’ll go to a smaller rear housing as I have an extra or even cam gears.
