Hoowdee!

The results are an average of 10 readings taken at 1 minute intervals driving at open road speeds (100km/h 60mph). There was no aftermarket system to get air up to the location of the intake (where the stock air box is located). The data needs adjusting for the thermocouple calibration, but the difference is only about 0.4C and I can't be bothered doing it. The engine is a SR20DE in a 92 Primera Te. Error values are 1 standard deviation.

Ambient (taken from behind the front bumper)
--- 20.5 +/- 0.3C (69F)

Engine Bay (taken down the left hand side of the engine, I guess I should get a pic of this or describe it more accuratly)
--- 40.6 +/- 1.7C (105F)

Intake
--- 31.3 +/- 1.9C (88F)

Feel free to hit me up with any questions...

Actually don't reply here any more. I decided it makes more sence to continue this discussion here:

G20 > Engine > Engine Temperatures...

Cool data! So the increase you measured is approx 11 deg C. A bit more than I expected, but not terribly bad. Might be interesting to see what it would be with some air directed towards your airbox.

What speeds was this data accumulated at?

Nice work.
