MN 2.5 Triton making 35psi???

[Adstar77]

They are on another planet mate.

Not 35psi at all.

Mut 3 and other scan tools don't factor in static air pressure.

Nor does your VDO guage by souds of it.

You have nothing to worry about.

Take 14.7 off.

The gauge is fine, its been tested and works fine.

What you have to remember, yes atmospheric/static air pressure is 14.7 PSI but my gauge STARTS at zero (regardless if the car is running or not) and ADDS 35psi above atmospheric.

So if the MUT is telling me I'm not over boosting then I'm making 35psi from the turbo. Thats it!

Tony is the most clued on man out their when it comes to tritons and I'd take his word over any mitsi tech or guage.

He's giving you knowledge not many understand so I'd just relax a little

Believe what you want but your getting the best free advise available, so as you put it, " That's it "

Yeah, I'm not having a crack at anyone but I just don't see how I can be making 35psi and it drives fine and shows no codes or anything and its exactly what Mitsubishi are telling me. I know some car salesmen will say what you want to hear but when I have multiple people, regardless if they are service or sales people, telling me it should make 35psi, then it really throws a spanner in the works!

What area do u live ?

What area do u live ?

Just north of Adelaide

Bugger could have hooked up a calibrated guage too confirm. 10 odd years ago a performance magazine did a test with a heap of different guages what was found most read true to 20psi and became very inaccurate when past it.

I don't think I'd be assuming that because your gauge reads zero at rest that means that it has taken barometric pressure into account. Do you have an obd reading that also says 35? Did they leave the mut3 connected while you drove it to measure this 35?

I don't really understand why you insist on believing the gauge and not on the advice that you've been given here - there doesn't seem much point in seeking advice if you have no intention of listening to it. Tony drives an 09 triton as do I - both owned since new. The most I've ever seen mine do is about 25 on the obd. Tony has tuned tonnes of these and even has 2 of the 2.5 engines sitting in his shed. If he says it's not making 35, then it's not making 35.

I thought you said your gauge went to 30 psi anyway, how does it show 35?

But the gauge has been checked and it reads fine. I haven't checked it with the obdii as I'm waiting for a dongle to come in the post.

No they didn't leave it connected as they didn't seem keen for some reason.

Watch the video in the first post and you will see what I mean when it hits 35 on a 30 gauge.

[hvac guy]

What was the guage checked with

[variflex]

Must say though that Triton sounds great

[Adstar77]

Just letting people know, there WILL be an update soon, just waiting till everything is sorted before I go explaining.

[Adstar77]

So,

Update took a bit longer than I thought (thanks Mitsubishi)

After many, MANY visits to mitsi, and trying to explain what my gauge was showing and what it SHOULD be showing, they finally sorted it all out, and even surprised themselves. They replaced sensors, tubes, pipes, clamps and electronics all with no difference. They finally resorted to replacing not just the variable vain actuator, but the WHOLE turbo.



Sure enough, the car started running 22-23psi. I'm still not sure what exactly the problem was, as they assured me the actuator was not the problem, but they have sent the turbo off to be "tested" so we'll see what that brings back.

So what can we learn from this lesson:
1) 2.5 triton's can handle 35psi ABOVE atmospheric pressure without throwing codes.
2) Some (not saying all) Mitsubishi dealers have NO clue what specs their cars are
3) Mitsubishi's warranty is the best in the business

Now, as a side note, I just want to clear up, if I offended anyone who contributed to this topic, I am sorry. I was just going off what I was being told, and I wasn't trying to s*** stir or anything like that.

Have a good one!

That's great it's sorted but I doubt Mitsubishi will let you know what the problem was.
If they do......be sure to let us know.

[Cowboy Dave]

Was it running okay at 35 psi though? You may regret going back to the lower pressures in the long run.

Certainly a weird one. The new turbo looks pretty. Hope I score one like that. Can you take a better photo of the letters/numbers on it?

[mattz]

Interesting that they've marked all the bolts too.

[Adstar77]

Well now that I'm on that dealers speed dial and on a first name basis with the warranty manager, I'm hoping they will!

To be honest, the car feels NO different. I think maybe because it was boosting so high, but not necessarily adding fuel, it didn't make much difference. In a way, it has kind of worried me that an extra (now reduced) 14psi hasn't made much difference. My 0 - 100 time hasn't changed, although I was using an accurate "passenger with a phone" technique. One thing I have noticed is that it seems to have gotten slightly quieter on boost. Doesn't have such a typical harsh diesel rattle if you get what I mean.

I've got one of those CD

You just need to complain about the oil seepage enough times and you'll get one also

[Cowboy Dave]

Something like this you mean?

[har05l]

I see nothing in that pic

[patrolus]

I thought that's how they came out the factory ?! Mine looked like that after 10.000k's ...

[Cowboy Dave]

Weird. It's blank on an iPad but visible on the PC.

[krazed]

all i see is a little bit of rust but no seepage

[Cowboy Dave]

Towards the camera from the rust there's a large black patch of oil - starts at the top close to the centre and runs out and down towards the driver's side from there. Also oil on the silver bit that goes into the black hose below/behind that. Would be more there if I hadn't wiped it clean a while back.

[Cowboy Dave]

I'm guessing we're not all seeing the whole image. Try this one:

[krazed]

thats better . Now i see what your saying
