Thread: Puma 2.2 Egt's

Also driving around generally it hardly goes over 250.

Good result. The Allisport IC on mine pretty much closed the gap between ambient temps and intake temp.
With the standard IC, the intake temp was about 50 degrees above ambient.

Thats a good result ☺. I found similar with my 3.0 auto 4jj1tcx in the dmax, couldn't get the upstream temps over 500deg driven as hard as i could. Bigger ic but stock exhaust. After the 500Nm remap upgrade i was hard pressed when towing 2.75t on a 30deg day to get to 675... a good tune and decent intercooler is a joy!!

Jc ☺

Great thread fellas.
1Nando, I have all the same mods in my 2012 2.2, except the oil catch can. (Might still do this!)
I will use this as a reference to where my temps should be when unstressed.
Out of interest, where did you mount your EGT gauge?
I'm going to fit a Redarc unit.
Thanks in advance.

In the collector before the turbo. A lot of people install the probe downstream of turbo and this is not a accurate reading. When i was researching the 2.2 egts i found a lot of people install the probe in the bung thats in the factory downpipe. Some of these people are getting 600-700 degree readings from that location, that would worry the hell out of me becuase in reality they could be 800-900 degrees in which case they are potentially causing damage.

Also i decided to use the egt probe and gauage from thermo guard industries. Ian was great to deal with and good price for quality items

Hightest i managed today was 476. To achieve this i had to floor it at 70km per hour in 5th up a medium gradient long hill until i hit 110km. Thats not bad considering im achieving that with 33s and it makes the engine work a little harder to achieve the same acceleration.
I did that with the family in the car plus a whole bunch of Christmas shopping, probably 2.55 ton all up.


Also noticed that the cooler temps today ran the egts a tiny bit higher. When i say a tiny bit maybe 10-15 degrees.

I put this down to the denser air charge providing a bigger bang for the same amount of fueling, thats my guess anyway. Still hardly sees over 280 crusing around

Hi guys,

So yesterday we left Sydney and arrived at Torquay (Jan Juc) in Victoria, we are doing the ocean road. Took 12 hours, 2 more than usual due to our new addition to the family (my 5 and 1/2 month old daughter) needing some extra attention and love......loved every second of it.

Anyway i have some interesting egt results to report. For those that are not aware please read OP for my mods and see the pic of where i mounted the egt probe (properly in the manifold before the turbo and not after).

So the goal was to drive in 6th gear and floor it up every hill on the way to Jan Juc to see what the highest egt i could get is, whilst always maintaining a minimum of 110kmph or increasing my speed up hills if possible. Also adding to this i was blasting the air con and was probably weighing in at 2.6 ton gvm.

The maximum i managed was 612c. This was a result of going up a very long hill just out of Gundagai in 6th at 120kmph and full throttle application. Im very pleased with this result because the car was managing to maintain speed and the egt was ticking over at a snails pace once it went over 590. Under normal circumstances i would not be flooring my car up such a long hill in 6th with the air con blairing and a decent payload in 27 degree weather. This was the only hill where i managed to crack 600c, no matter how hard i tried.

The average egt reading would be 420-450 throught the trip. I've ordered a scan gauge and am keen to see the relationship between coolant temp and egt. Will post some results soon as i do.

Comments welcome and i hope you find the info helpful.

Hi guys, update:

So we ended our trip short because of the oil leak issue ive got going on at the moment and decided to come back home yesterday. Arrived at home this morning close to 2am.

So yesterday we were driving through 34-37 degree weather, it was bloody hot! Due to my oil leak issue i was driving normally and not hammering the go fast pedal. Basically sat on 100kmph to 115kmp depending on up hill, down hill etc. My average egts were 380-420. Highest spike was 588 up a very, very long hill. As soon as i saw the 588 i backed off into 5th and down she went to low 500s. Around midnight my egts were 330-350 at 110-120kmph, thats nice and LOW.
Very impressed, it was VERY HOT and the egts did not go over 600 once. The highest to date is still 612. This is excellent considering the 3ltr patrol for example can hit upto 800 degrees celsius according to some posts ive read on their forum.
A/C not only effects power but also increases egts significantly in the hot weather. Again if you have an egt of 550 post turbo in that sort of heat i would 100% back off as your more than likely over 720 degrees celsius.
I would say that out of all the mods I've done the exhasut has had the biggest effect on my egts, id say even more than my intercooler. I say this becuase although the cooler reduces intake temp it also increases power and there for it kind of balances itself out, the exhaust however lets the engine breather easier.
My 2 cents, hope that is informative.
Nando
