This data is very strange! It is probably B*sh|t.

Is it just me, or did they not do any of these tests on the same day?
The temperature data shows the red line that was done with an ambient temperature of 50 F.

All other tests were done with the temperature from 58F to 75F.
The data on the graph is manifold temperature above ambient, so you are telling me that stock that engine reaches 50+138F just by idling? That is 188 F!!
Funny, in the middle of the texas summer My turbocharger outlet temp at ~88F ambient temp posted 191F maximum temperature at 5.75 lbs of boost!

How is this possible that they can reach temps that high with ambient temps of 50F?
My car here in the winter with ambient temps of 50F was only reaching temps of mid 90'sF after it had been warmed up. I just checked it 3 weeks ago to see how the intercooler might be working.
In arizona when I was using my obd scanner to check out the car, my idling temp after driving in 100F ambient was about 145F.

Now I grant you that this is intake air temperature that I measured and not the actual temperature of the intake manifold. However, the inital part of all the graphs starts off low and which I can only assume is the 60mph test, i.e. the coolest that the engine will get. In the ambient test they quit driving sooner and idled longer. In the spacer test they drove longer and the one graph never heated up? What is up with that, did they not stop the car for that test? It should have heated up a little bit in a similar fashion.


This data just doesn't make sense.

Heat transfer is exponential with regard to the temperature differences. If you have two heat sources that are widely spaced with regard to temp, heat will flow rapidly from high to low. In the presence of a heat sink they temp will remain steady as the heat flow through it.
