Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Cross Post from HPDE / Racing What is the acceptable range of water temp for a street driven 996 on track days? What is the point at which you should pit if it gets too high. I have a dash mounted OBD II Scan gauge. I can monitor water temp and MAP Air temp, but not oil temp. I am starting to experiment with higher rpm (lower gear) driving and seeing water temps up 7-8 degrees hotter. Ambient temp ranges 70 - 83 degrees. Any input would help. Some summer track days ahead, I don't want any surprises. David

I've seen water temps go as high as 210 on my car in 80+ degree weather at the end of a 25-30 minute run. ideally, I'd prefer if they were below 200. This was with a new water pump and all 3 CFS radiators. I monitored oil temp and it would regularly get to 230-240 after about 10-15 minutes. I had a 2 qt mantis pan with a oil cooler that ran up front, so that helped. I'd say 210 is probably safe....ish....
