Temperature measurements under CV Boot Shields

I had a change to log some temp data on my 95 with OEM shields which are covered with sheet aluminum cut to the same size and shaped as the OEM shields. The first picture shows the mounting of the thermocouple on the underside of the shield. It was mounted with a small piece of wood (1/8" thick) which was supposed to act somewhat as a insulator between the shield and the TC. This was located on the back side of the shield near the bottom edge.

The second picture shows the shields as installed on my car. Note that the back part of the shield is almost directly under the Y pipe.

Third figure shows the temperature data from start up, driving, stopping for gas, driving, stopping for lunch, driving home and cool down in the garage. Pretty much self explanatory. Time is in minutes from start up.

I hope to do another extended test with the TC mounted differently to better isolate it from contact with the shield.

If you are going to tell someone how to remove a bolt you should at least know which way to turn the wrench.

John,


From the photo, it appears your car has an OEM Y pipe which includes cats. Correct? Do you also have OEM primary cats or test pipes? Just wanting to check if this data represents a stock, all OEM cat equipped 355.

Y pipe is stock. Cats are Nouvalari sport cats.

John,
Forgot to ask, do you have stock heat shielded OEM headers or something else?

Stock headers. Stock Y pipe. Nouvalari cats. I doubt the type of cat make much, if any, difference except some OEM cats were shielded, some were not.
