Fuel Economy For R34...is This Right?

[Howie]

i'll just got take of my fuel lines and let it run out onto the street, then i'll win, lol

We have a winnar

[satanic]

If you unplug your fuel lines your car ain't running Technically you're not "driving" so you don't win sorry

Yeah 250kms; most of that tank was spent going nowhere; just revving the engine trying out some new stuff we did.

With that in mind; you could leave your car idling for a day and you get 0kms out of a tank!

[Howie]

Say have you guys seen the 98 Octane they sell at Liberty? It's about the same price as regular unleaded because it contains more ethanol, but apparently on rexnet the guys have found good experiences with it.

What are your thoughts on Liberty 98 Octane PULP?

[satanic]

Wouldn't go near it... sorry!

Fuel is not that expensive at the moment; staying relatively stable when you think about it. Meh; if you think 98RON from BP, Shell or Caltex is bad - try getting your fuel from ELF (113RON)

The race team opposite us purchased 105L for $1,100.00

Thanks for the tip Stan. I've just done a search on SAU... guess the overall sentiment is without a full retune it is not quite suitable for our pre 2005 skylines.

well then i'll just poke a hole in my tank then go for a drive down the road, and drive with my left foot on the brakes so i have to keep it floored to go anywhere.

[satanic]

But you're still going somewhere...

Why not just jump into the car; and just hold the revs down 0kms, 65L

Cool my car uses infinite L of fuel to go nowhere

thats part of my problem, the maccas here sux, so you spend ages sitting in drive thru, and its too cold to turn the car off.

[sloutch]

Haha; let's play "who has the worst fuel economy"

Mate, on that, i'll let you win no worries

250 a tank is mad. You must be hitting 1 bar boost constantly eh?

[satanic]

mad082; funny guy~

White_Thing; 250km was a once off - we were doing some really stupid things Normally floats around the 350-400km mark.

[mad082]

Normally floats around the 350-400km mark.

i haven't got over about 320-330 since i've had the car, but i am only running stock ecu, no piggy back, so i'm running pretty rich. and it is hilly as hell here, so that chews up a bit more fuel. put a new o2 sensor in hoping it would help but it didn't. but i am also running pretty high boost, and just put in a remapped ecu which is dumping in even more fuel. but getting a safc when i get my tax back.

[satanic]

Should help it out...

[peteness]

yeh i havent went over 350km a full tank is this bad? unliek most of u guys cars my one is stock not boosted with only a cat and pod the rest is stock is this bad O_O (manual transmission)

[satanic]

For a manual I'd say that is quite poor fuel economy - some guys I've heard are getting 500km from their manuals

*lucky for some ehh*

[Chris_R33GTSt]

Yeah I got a stock manual S2 R33 gtst with pod filter and cat back HKS 3". I drive 50/50 pretty enthusiastically/cruising and im lucky to see 240-300kms to about 55-60 litres. Would a SAFC help to reduce fuel consumption? What other mods could reduce usage as I am spending S**T loads on fuel atm.

[Lithius]

I've never gotten under 400km a tank with mine, it's 204rwkw and manual. I usually get around 450km off about 50L.

[Busky2k]

Damn some of you guys are using some serious fuel huh. Its just as bad as a Gen III commodore which is twice the size!! I'd say get your O2 sensors checked and try keeping off boost when taking off the lights if you can.

[Beauie]

my r34 - cat back n pod will get 300 if i try n drive slow - will let u know how the injector cleaner for $15 goes:P

[eMsta]

I think i will be getting the car checked out at my next service - it does take quite a bit of fuel for a relatively stock r33 - but then again, maybe its the age thats showing....

[Cubes]

Thanks for the replies guys. Well good to know it's not uncommon then. I'm coming from an R32 Gts-t, and that averaged around 10L/100km. Even with an added 500cc and variable timing, I wouldn't have thought the R34 GTT would be that much thirstier.. oh well

Might try freeing up the exhaust and running a SAFC and seeing if that helps things along a little.

It definitely gets me why fuel consumption vary's so much between the models.

Its 100% not the displacement as my fuel consumption hardly changed going from the 2ltr to the 3ltr.

Normal driving (no open road or peak hour, just local short trips with a 50-80km/h speed limit) with the odd squirt see's on average 11L/100km's, dipping to 10.5ish if i'm really cruisy for the whole tank.

Last tank of juice I drove it hard, every set of lights was up on boost in every gear, usually i short shift around at max 2000-2500rpm with almost zero vac and get it in top gear asap and keep it in decel fuel cut for as long as possible. But yes.. this tank, many hills squirts, reminded me why I bought the car in the first place and suprised me how well they really do handle. But yer.. last tank... Bumped up marginally to 12L/100km's. Or.. 430km's to 52litres.

The cars running clean injectors and the o2 sensor has been replaced with a genuine item. I replaced the o2 sensor when fuel economy dipped to 350km/s per 50litres. It made no difference, replaced injectors (larger items and trimmed fuel in pfc). Fuel economy instantly back. I doubt this is every ones problem but it was mine.

Maybe the R33/R34's VCT actually hurts economy.
