He is referring to my engine temp. My qs was, what is the highest oil temp my car can take ? Thats why he said "for the sake of your engine and the radiator can take more than that."
Also to add to me previous comment and since I am testing a radiator upgrade right now with a couple of other things.
The biggest factor for cooling in the radiator that I have seen so far in testing is ambient temps and airflow. Have noticed fairly consistently if I am behind a car in the highway the oil, water and IAT’s start to climb slowly thus reinforcing the importance of airflow.
The second thing I have noticed is how ambient temps wildly affect the cooling capacity of the radiator. Remember it is just a giant heatsink with surface area. Now try cooling the radiator with a blow dryer on high heat, it limits the ability to dissipate heat. So some people have reported no cooling issues. But from my testing again, the recovery time and management of temps varies greatly depending on how hot the ambient air is.
For example if you are running the car in the 60’s-70’s ambient temp there is a greater delta from the surrounding air compared to the radiator thus it cools more efficiently. As soon as temps get into the high 80’s and above the cooling system struggles a lot more to dissipate this heat.
On the other topic of max oil temps and max water temps. I personally like my water temp to be under 240, anything above that I shut it down. As far as oil you can dip into the 250’s and it will hold but film strength starts to become an issue after that mark.
These pics are at the beginning of a pull and then at the end of a pull from 40mph to 120mph. You can have a reference of how hot it is outside since those IAT’s are with the car moving.
correct, if you vent the hood the car will have an easier time getting rid of the air in the engine bay thus increasing airflow. The front bumper from the factory I find the airflow pretty good. It is the heat extraction that is the main issue.
Why not try a drag race mini radiator in place of a standard second radiator?
Do you have a link of it?
Ya , the intercooler, oil cooler, 27won snorkel are blocking my pwr radiator. I have to customize something so that air flow could pass the radiator.Also to add to me previous comment and since I am testing a radiator upgrade right now with a couple of other things.

Pretty much confirms what I have seen, so with upgrading those parts, airflow is the other piece of the puzzle.
Interesting response. The engine oil temp value was clearly copied and pasted from an erroneous source. The car will be in limp mode, oil will have broken down, and the heads warped well before 1,292 °F.Honda answers my qs of what is the highest temp that Type R can handle.
Ya someone is BSing me.
