Fuel Consumption? How's Your C34?

[SNEEZYC34]

Hey guys

I have been trying to figure out how my stagea goes with fuel.

I have done my research and seems normally they should do 400kms per 60l tank.

I drive 80kms to and from work every day so I do 400kms a week. I fill up $70 premium every Monday and lasts till Saturday. Premium price varies obviously.

Works out about $14 a day for 80kms

What's everyone else getting. Does my figures sound about right or is my stag using a lol too much fuel??

You should talk litres per hundred to be more accurate.

Mine is a rwd with rb30 bottom end. To and from work 12ks each way uses 13.3 litres per hundred. Have been meaning to tidy up cruise part of tune for a while as I think it could be better.

[SNEEZYC34]

Approx 11.25 litres per 100kms

[Ben C34]

I would consider that good.

[BigDirtyJase]

I'm assuming your commute to and from work contains some freeway/highway driving?? 11.25 sounds very good...You have to remember Stagea's (S2 I think...dunno if the S1 or the M35 is the same) have a 68L fuel tank in them

On the other hand - check out http://www.skylinesaustralia.com/forums/topic/167866-stagea-fuel-economy/ - There is a discussion thread on fuel economy

My mates 2004 PNM35 3.5L gets 8.75L/100km for comparison. That's around town/ suburb driving.

S2 c34 rs4s gets 400km from 3/4 tank (have never run it into the last 1/4) if I drive like a total nana with only one or two slight boost moments. 350km if driving a little more spirited. Driving on the highway between adelaide and melbourne I got 550kms approx.

(I dont know how big the tank is to do ltrs/100km) but would assume its between 13 and 16 lt/100km average. Fair heavy considering the charger (with a 4.3ltr 4bbl auto) does about 15-17 lt/100km.. and it weighs about the same lol

Factory navigation system FTW. Green leaf screen throws up the numbers /100km

Is there a system available for the c34 that can do the same?

Not sure, all the searches on Japanese Yahoo auctions searches came up for M35.

There are a few guys that can do the language conversion software, and the units are worth nothing in Japan, basically throw away $40 nzd. I guess it must link info from diagnostic software/on board computer to the nav screen?

Yes, it is called ECU Talk, here is a link for it,

i have one in my car, it is useful not only for L/100km but all other diagnostics.

can be used with a laptop and consult software to check for faults.

great investment http://www.ecutalk.com/consultlcd.aspx

Ahh, nice. Thanks for that (sorry for the slight thread hijack btw )

All good hahaha

S1 RS4V - does around 12.5-13L/100km "round town" ie Canberra roads. Country highway is 11-12L/100km, freeway is on the lower end of that.

Fuel economy improved ~1L/100km when I installed a hypergear hi flow turbo and a mv auto stage 2 shift kit.

Can't say scientifically which did what improvement, but my money would be on the turbo.

ive found a noticeable change in fuel economy since having a stage 2 shift kit fitted to my S1RS4

[nicksamaniac]

S1 rsfour, manual converted.

Only engine mods are rear resonator and big fmic.

14l/100km regardless of hwy or town driving.

Pretty much 100km per 1/4 tank or 400km/tank, I always fill up at around 350km.

2000 STAGEA C34, DONE 12L/100KM

Its possible, though I can't think why. The box runs a slightly higher line pressure, so if anything there should be more energy lost through the transmission. Perhaps not enough to make a difference on economy. MV autos said it shouldn't make a difference.

The larger turbo should be less restrictive and doesn't spool up at the whiff of a throttle. It now stays off boost unless Im giving some throttle over 3k rpm. That should be more efficient with the stock ecu.

Still, everyones results may vary. I read a post once saying that the stage 2 kit would effect the lock up converter, and I havent found that to be the case at all. Can't see how it would be either.

Bit of an update

I had a full tank and got 480kms so I'm fair happy with that

[Cheddar]

I've not worked out the L/100 km's but I'm lucky to get 330km's out of a full tank
