Default Temperature D24TIC

Because the D24TIC has a bad reputation in cooling i was wondering what temperatures my D24TIC is running at.

I made a digital temp.gauge out of a kit (from a online-electronics-store).
With a modification i can measure 5 different temperatures at different places in the engine.

At this moment (juli) the temperatures in Holland are high, 30 celcius.
I took a drive starting with the engine "cold" so reading about 30 celcius.
With my son next to me we measured 3 temperatures every minute right from the start.The results are given in the graph below;




Keep in mind that i drove the car normal, not exceeding 100KM/hour at the highway.We drove about 7-8 minutes to reach the highway.The roads in Holland are pritty flat so there's no extra power needed to take any hil.

The colours of the graph-lines are explained as follows;

orange; coolwater in the cilinder-head,running toward the radiator
bleu ; engine-oil , directly measured in the oilpan/sump
purple; coolwater coming out of the radiator towards the engine
green ; no temperature, this is aprox. the distance in KM starting from home

The other temperatures i can read are;
- inlet-air-temperature between turbo and intercooler
- inlet-air-temperature from intercooler to inlet-manifold

To give a impression of the gauge i made a short movie of my home-build-navigation-pop-up-mechanism with at the and a look at the knob for selecting the measure-device and the display reading the temps. in celcius.



If you're interested in the navigation-project, here some extra pictures;

Back to the temperature-story; i think the temp. difference between water in and out is pretty close to tow a heavy load uphill at a warm summerday......
So the first lesson i took was connecting 2 extra cooling-fans (wich i already installed last year right behind the intercooler in front of the radiator.
