What is the normal operating temp for the Z?

Unless you want to cruise around the track in 6th gear then you need a cooler as you will be over 280 before you can finish your 3rd lap. Auto-x is okay without a cooler as you have a good 10 minute cool down period between runs.
Most people consider normal operating temperature to be 180-240F with maybe a few trips to 260F and back. Once you get above that even the best synthetic oils start to break down.
