Anyone measure engine bay temps?
Curious to find out how hot my engine bay reached during a ride home, I attached a data logger to one of the hoses, just outside of the battery compartment. After a 20 minute ride home during which the oil temps reached 210, my engine bay temps peaked at 137.4F.
I should note that I have some excess cold coming in from my CAI setup and have removed some of the hood seal on the right side.
Has anyone else done this? If so, what did you find?

If you have automatic climate control with the external temp. sensor, you can make an extension wire for the sensor, then place the sensor any where you want. I did this a few years ago to check the temp. inside the air intake when I was changing the intake. The temp. has a max of 150 degrees on the readout, underhood temp. around the throttle body is above that in the summer.

Thanks. That would certainly work for what I am doing.
I happen to have a couple of data loggers at work and was a bit surprised that temps near the outside of the battery compartment didn't get warmer. Now that I think of it, though, the max temp my logger saw was pretty close to my pre-CAI intake air temps after idling and slow-go driving. After CAI, my intake air temps never exceeded 104F, even after 20 minutes of heavy traffic on an 85 degree day.
I am working on determining where I will position a professional "catch can", which has a max operating temp of 180F.
