9 km/l (11.1 l/100km)for 2.5t AWD vs 10 km/l (duhh 10 l/100km) for 2.5 Di AWD.

here is the full list.

Haven't driven a VQ25dd so I don't personally know.

Will check "official" numbers tonight/tomorrow :(

  • 1 month later...

i'm quite heavy on the foot and i seem to get around 450km's out of a tank..

and i am running VERY rich :ninja: (plops quite alot)

once the PowerFC gets installed it should bump that figure up a bit more :P

got my RS Four S down to ~ 10.5L/100kms of 95% highway (to the Hunter Valley), but averages out to around 13.5L/100km around town (air con always on pretty much)

not amazing, but not too bad

EDIT - pretty much 100% stock car

So these things have a 68L tank? Im getting around 400 per tank, or a bit less depending on how spririted I drive it :)

Also, contemplating a Power FC over an SAFC. Been told SAFC are ok, but not the best to do as it just messes with the true MAF/MAP reading. Take much to get a PFC tuned for economy and WOT power?

Might have to also try this Boost98 :blink:

{edit} just found they also sell a new one 'Premium 100'

forgot to add, running on either Vortex 98 or Optimax

premium 100??? where sells that?

That's what im running until the new injectors come for the e85. I get the same economy on the 100 octane as the BP98 I used to fill with.

United are the only suppliers left I think.

oh ok i havnt noticed. can you feel any sort of performance gain? and is how much more a litre is it on average than bp98 which is what i use

It sells for around the price of BP 98, I run it to stop the ping I was occasionally getting. I am able to bump up the boost a bit more now, if I want.

According to United, the fuel is at least 100, usually 102 octane.

The standard ecu will probably loose economy with it, my mates XR6t did, due to the ethanol content.

Dont you dare put a SAFC on a 26 unless your really stripped for cash.... Its not hard to find a power fc for that car. Do it once do it right. You;ll find many stag drivers get the safc sitc combo as they have an auto and are restriced to computer changes with out spending big coin :)

E85 would be best, and at 99c bugger the economy. Lucky the M35 has an 80 liter tank. :devil:

Works out about the same anyway.

E85 is 25% cheaper than PULP98 and you use ~20-25% more of it.... but it is much cleaner and allows for a much more aggressive tune :)

Hmmm, well for me it works like this:

More boost = :) = more boost = :huh: = more boost = poor fuel economy :)

I'm still getting a minimum of 13L/100kms driving to work and back (at least 40% of the trip is spent cruising at constant 50 or 60km/h - so not exactly heavy traffic). If I drive it how I like to drive it, its closer to 14L/100km. Not a big difference...and the driving satisfaction outweighs the extra fuel cost IMO. :)

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
