G'day All

No I am not thinking of entering it in a drag race, but trying to figure out if the engine is down on power at all. Fuel consumption just recently has risen, and it feels like it may be down on power a bit, but I could just be imagining it. So I figure the simplest way is to put the foot flat to the floor on a flat section of highway. Which leads me to my question, has anyone done a 0-100km/h test on their 3.0 Patrol and what was the time? Mine is a auto which will work in its favour but 33in tyres that will work against it, please don't reply if you are just going to bag the 3.0 Patrol.

Thanks in advance

Snowy

I'd start by seeing if the Air Flow Sensor needs cleaning.

Already tried that, and thinking about how the MAF sensor works if it was dirty it would cause the turbo to over-boost giving more power, where I may have the opposite situation.

If there was anything wrong with the MAF...your engine warning light would let you know. I am pretty confident of that.

Take it Nissan...if it is running rich and being overfueled (using more fuel than usual as you say)...BOOM

With all the 'professional' !!! opinions out there about what causes these engines to sometimes to let go...one I have heard from a nissan service centre is that the ECU may malfunction injecting too much fuel causing the BOOM.

If detected, I understand Nissan will replace the ECU. They did on mine.

Cleaning the airflow sensor does nothing! i have tried it on several patrols even check terminal resistances between a dud and a new one all the same the only answer is to replaced if it's in doubt.

If the air flow sensor is caput the turbo will not over boost but exactly the opposite. When mine got dusted the power was down quite a bit and it would take forever to spool up. Overtaking was impossible and being an auto, getting it to kick back was also impossible.

When the revs were au around 2500 to 3000 rpm things seemed normal, but under that it felt like I was driving a landrover.

Replaced the MAFS and no wuckers!

That's not true a faulty air flow sensor usually causes them to over boost! but they run crappy with poor fuel economy.
And in the end boom!!!

I did not experience crappy fuel economy.

Over boost together with over fuelling would produce more smoke from the exhaust. When I had trouble with the MAFS I did not get any smoke from the exhaust except when absolutety flat to the floor. When I did this the engine would not go at all, it would just LUG at 1800 rpm and take forever to climb in revs.

This is not a symptom of the turbo "overboosting". It is infact the very opposite! Another way I could tell that the turbo was not spooling up is there was no audible turbo "whistle" as I can normally hear.

My intended passenger for an upcoming trip asked what the speed limit was on a particular stretch of road. I said dont worry, its doubtful that we'll see 100k/h :)))

Hi there Footloose, try a 2.8D hilux I bet its slower than your 80, flat knackers 125/130 with no head wind and slight down hill run, only ever tried it once was revving its nut off ar nearly 4g, will sit happily at 100lk all day on the flats even with the air running, so I thought I would buy a pair of those dark tinted headlight covers so when I'm approaching a hill it will not see it in front and might actually keep the speed up LOL. Regards Steve M

Footloose,
You've reminded me of my misspent youth.
A group of us went to the Cook Islands years ago to play Rugby Union. We where going to be there for a few weeks and to be driving ourselves around. (At least as much as you can on a Pacific Island)
One of the responsible adults, read 25 suggested we all get Cook Island licences. So off to the police station we go.
All the paperwork is done accompanied by the poor local copper trying to work out, "why bother?"
Next thing, one of the touring party pipes up and asks the copper "what's the speed limit?"
Coppers reply? A blank look followed by, "Why you in a hurry?"

Cracked us up!!

Geoff.

Speaking of ..."in a hurry"

Was camped at the Bar at the Pub on Thursday Island some years ago, looking up at the clock above the Bar. Through the beer haze, I noticed the clock had no hands.

And under it a sign
THIS IS THURSDAY ISLAND TIME...

I did read a road test where they gave a figure.

What was it - about 22secs ???

Bit of a guess I think. Was tha tthe 400 metres?

If it takes 30 secs or more maybe you do have a problem!

Who is going to do a test for Snowy?

LOL, Take it down to Whoop-Arse Wednesday and run it down the ¼ mile.

0-100km/h, The X can do it in under 9 Seconds from memory.

Common people lets get some times posted up. LOL

HeHe, maybe we should have an EO trip to the local drag strip and see who runs what times, it'd be a laugh wouldn't it seeing two 4.2 oilers doing the 1/4 mile in 20+ seconds followed by a couple of young punk rice burners doing 12's!

Sorry to go off topic Snowy,
but seeing as Exploder asked, my 2 tonne wagon "fourby" does 0-100 in 6.4, and back to zero in another 2 sec. These are factory figures of course, and they wouldn't lie, would they!

But you'll do me in once you get off the gravel or bitumen, so horses for courses, hey.

Cheers

Snowy it is approx 16.4 secs 0-100kmh for your auto.

Not for reasons so much of speeding , but I would reccomend to everyone to do such basic tests as a means of knowing how their car is going.
But be warned , its amazing how many snorkels filters and oversize tyres actually slow cars down.

Its also better to do it when car is in good order though so that you can get relative performance measure.

Also doing 0-100kmh is not best option as there are already many varibles in this type of test and some need to be removed to make results meaning full.

A more accurate test is to do it on a known piece of road and stick to one gear.

If you can use a GPS set to record each 1 second then you can get real
results , indepenant of your speedo/tyres and plot them out (Ozi-explorer can be used to do this to)

I regularly use a known piece of road with gentle uphill gradient and start of in 3rd gear from about 1000 rpm and take it out to 5000 rpm.
