We fit both cylinder banks with knock sensors along with Temp sensors. The temp sensor can be seen in the photos on the # 3 cylinder. From memory we fit to the #3 and #6 cylinders. Once I have the other side assembled proper, the sensor position can be seen.
I'm re checking some flow numbers with the middle cylinder, with the Intake attached again, as we have found that the middle cylinders seem to lose a little air flow in the car. Not really sure what is going on, so we are trying to replicate as best we can on the bench. The middle cylinders always have less pressure when measured and in an effort to get all cylinders to make the same or near same torque, airflow is critical. We found this on our 4.1L development and want to see if its the same for this engine and all.

Hey Niel
Is this temperature affecting pressure once the engine is running , or a mechanical thing that you are seeing on the bench as the engine is assembled ?
