Acceptable water temps for a 996
#16
Agreed with the earlier ranges quoted. I was typically in the 100-105C (210-220F) range. As an FYI you can display the actual water temperatures on the digital display in the center console. You need a particular button combination to have the HVAC display read out various OBD information. If you search around you should be able to find a guide. I typically had the water temp displayed while on track to keep an eye on things.

In a 996/m96 motor?!
Real time data, I did a three hour test and tune at WSIR today (103 ambient, 125 track) and the car never exceeded 203; longest stint was 30 min. Under race conditions I usually back off if it hits 210, but that could be bad info I recieved somewhere along the line. No clue how you could get the car up to 220.

For whatever it’s worth, I found leaving 3-500 RPM on the table in the 996 kept it really happy. I had all stock cooling and ran in pretty good heat here in SoCal. Plus I don’t think it was really much slower that way. I would rev it out further to save a shift in a couple areas but that’s about it. It’s a torquey motor and I *think* it makes peak power (or at least falls flat) before redline.
It was probably the most reliable car I ever owned.

That last 3-500 RPM can really make a difference in temps in some cars. If one is driving well, it shouldn't affect lap times all that much at all.
Also, for some cars, all that is really up in that last 500 RPM is noise anyway. A little bit of mechanical empathy can go a long way.

There is no sense in pushing my motor to redline at a HPDE.
