Has always been available to order as parts and not a factory option except the Middle East where all Carrera's come standard with it.
The centre radiator does not come with the X51 kit
9A1 peak oil temp ~ 112 to 115 degrees C, water temperature 90 degrees C and constant (three radiators GTS - air temperature 38 degrees C) and 9A2 peak oil temp ~114 degrees C or 237F, water temperature 90 degrees and constant (two radiators - air temperature 36 degrees C). Race conditions for both.
All for extra cooling if its needed - but, so far so good.
R-Rated, Aquamist???? water/meth injection - used to reduce internal cylinder temps to minimise the potential for early detonation and thereby allow increased boost and advance in timing. Big difference between DFI and Port injection. DFI in its own right is great for anti knock prevention or were you thinking of intercooler/radiator water spray kits???

They have DFI and Port injection. It actually retards timing and spraying in the pipe post turbo will help keep things cool.
Hot Climate and/or Super Hot Climate is specifically for Middle Eastern regions where temps regularly exceed 100+ degrees. Although we dread our summers down here in Florida, we're still not considered a "Hot" climate.
For normal driving a center radiator isn't a requirement and Porsche doesn't include them in their builds. However, even with a daily driver the addition of a center radiator will never be a bad thing. For track guys, this is a must, especially for the new turbo motors. 991.1 and 991.2 radiator and hoses are different, along with the new ducting pieces. This is a great addition to keep temps down and you have the benefit of factory parts. Also available for the 718

i live pretty local to you and have a 2017 991.2 GTS and I track it. What’s the labor charge to have this installed? Thanks!

You just think the water temp is a constant 90 degrees C (194 F). I think it's moving around quite a bit more. I recently plugged in an OBD II dongle into my 991.2 to read some of the engine parameters using the Torque app on my phone. This app can do many things, but one of the key ones is tap into the car's sensors and display their values.
I was looking at the water and oil temperature readings from a cold start, where the digital displays for oil and water temperature in the multi-function display, correlated well with the Torque displays--and ambient temperature. As the car started to warm up in normal driving, in 30-40 degree winter weather, the water and oil gauges remained in respective sync until about 110 degrees on the water gauge.
At that point the car display started to show a water temp that was higher than the Torque app. When the car was showing 130 degrees, Torque only had 120. At 155 on the car, Torque showed 140. And when the car first hit 194, torque was only showing 179.
Then, as we all know, the car's water temperature gauge freezes at 194--short of major cooling system failure. However, the Torque display continues to rise until it surpasses 194 and keeps going. On a routine airport run, with the car fully warmed up, the water temp on Torque was 219, while the car was still showing 194. I'll be curious what happens to the water temp at my next warmish track day.
Meanwhile, the car's oil temperature display tracked much more closely with Torque, within a couple off degrees almost everywhere. Though I haven't had the opportunity to drive the car hard with this app, it does seem that the car's oil gauge gets sticky around 225 degrees and wants to stay near there, even when Torque is showing a lower oil temp. But the largest difference I saw was 6 degrees.
Interestingly, and not surprisingly given that the car has an oil/water heat exchanger, during normal driving, water and oil temperatures run about the same according to Torque, even though they might be 30 degrees apart on the car's displays.
I think what has happened here is that Porsche, like seemingly all other car manufacturers, has dumbed down its water temp gauge. In a typical car, the water temp gauge start low, the needle moves to a position in the middle of the dial--or just under halfway--and never moves again, unless you blow a hose and lose your coolant. This avoids service and warranty claims from ignorant drivers who don't understand that water temperature changes with ambient and driving conditions. Sadly, Porsche seems to have applied this philosophy to the digital water temp[ display in the MFD.
