I’ve opened up my front nismo bumper and built air dam in front my intercooler to direct all incoming air towards intercooler/radiator. After this last track day I noticed huge improvement with it. 20min session needed one slower pace lap towards end of the session to cool down the temps and then finishing off with one or 2 hot laps. With this cooling mod and stoptech bbk, 80F ambient temp, this one was one of my most enjoyable track day i think I ever had. I have 2 day event with TrackXperienZ following week so possibly I’ll sign up for one day with nasa.
Here’s the picture of my air dam.

Not sure why people think 230 F is excessive coolant temp for a VQ on the track. It's normal.

What would you say it is the safe coolant temp? I could never find any good info.

Bardabe Performance Tuning and Specialty Z both agree that those numbers are safe for a track car. I've also been hearing from Z32 and 350Z owners that those temps under high load are completely normal.

For the stock radiator, you'll know your overheating when the temp gauge goes one dot past the middle. Once that happens, the temps will continue to climb unless you shut it down.

Agreed! The same with oil temps at 245 or 250. My car ran fine at those temps.
