R33 Fuel COnsumption

[Cubes]

The so called 'specs' on the 33 state it should be 9L/100km's and the 32 should be 10.5L/100km's.

Damo,

I too have been keeping a record of my fuel consumption over a long period. I started with cat back exhaust and pod and have kept a record of when I did mods, long drives etc.

From memory im getting about 13L/100km in city type driving.

Mods include full exhaust, EBC set all the time at 0.6bar, high flow turbo, BOV, pod, clutch, tuned powerFC, FMIC.

When you post yours up, i'll post it in the same thread for comparison - mine is in excel format.

I sat behind a 33 today blowing major major black smoke on boost. Wasn't that quick either, quicker than a std one but obviously no powerfc.

Had big exhaust that I could have fit the cat up.

MRK25T,

Seems like a hot topic at the moment, Another thread has started under the General forum. I might post my results so far this weekend. Doing it on Excel is a good idea.

i have manual r33, stock boost, cat back exhaust and air pod....

i consistently get 450km with a bit a stick, about 550 driving like a granny...

have tried optimax for a year, just changed to BP ultima, havent noticed much difference yet but still keeping an eye on it..

Damo,

I look at the excel document last night and it sugests that I have recorded every fill-up since October last year... so nearly a year worth of entries.

Work out the mean for the summer months and the winter months.

I fogot to mention I got a large fuel pump and regulator about just a week before I got the powerFC tuned. I guess any gains in economy with the powerFC has been swallowed up by the fuel system.

If the powerfc is tuned properly the fuel pump won't make any difference to fuel economy. The only time it will make a difference is if you tune the powerfc then fit the bigger pump.

I drive granny style and get 250km out of a tank, does anyone know of any performance joints that can fix my problem.

cheers

Whats with the 40L tank?? 250km out of 40L is not all that bad...its not great, but not bad. I regularly get 400-450km out of 60L, where you would be getting ~375km.

The fuel gauge in the R33s is a little deceptive. The empty line does not actually indicate a full quarter. Mine usually does 350km when the needle hits the empty line, then 50km later the fuel light comes on. I can usually drive around for 30-50km with the fuel light on.

if u r concerned about fuel consumption u should drive a none turbo like a celica then u'll get 600 k out of 50 lts or itegra about the same . when u drive turbos u dont worry about fuel , try driving a hot coome then u 'll see how much fuel u use . 25-30 lts per 100 km .

33's and 32's don't all chew heaps of fuel.

Some are spot on the specs as released from the factory i.e 10.5l/100km's for the R32. Mine appears to be pretty spot on as are some others. BUT there are some out there that get simply crap fuel consumption.

[MRK25T]

Below is a link to an old copy of my fuel consumption for my R33 s2 skyline. I'll update it when the current one (when I get around to it). Let me know what you think.

XLS spreadsheet of fuel consumption

I have posted my fuel figures in the automotive general section

here is the link

Good work MRK25T, Makes mine look pretty simple. How did u give a direct link to the xl file. When i tried to attach the file it said only certain formats are allowed and that was not one of them. Hence I had to zip it.

Ok just got a EL Falcon Oxygen Sensor - Very similar to R33 one. Costs $77.00 at bursons. The original r33 from nissan costs $280 (No Thanks). Got my mechanic to cut the r33 sensor and soldier the el falcon one on.

And guess what. My fuel gauge is barely moving now, i cant believe it ive driven at least 100km and only a very little drop in fuel. Very good consumption now.

So now i reckon ill get 500-600km out of a tank that i used to get 250km out of before. I am still yet to clean my afm so hoping for better consumption.

Oh yeh power is that same as before. Hope this help guys. And if you get crap consumption go and get it changed.

Cheers

i used to get 420kms to 50litres or so on 7psi stock set up, now more like 260kms on 17psi with t3/4 turbo and support system mods.
