I track my 997.2 Turbo S. Oil temps sometimes get a bit too high for my tastes at 120-125 degree Celsius.

Does anyone make some sort of upgraded cooling system that would reduce my engine oil track temps?

You might not get an answer on this; part of the problem is the 9A1 engine is not a dry sump the same way the Mezger one is. It's elementary to run an oil cooler off the tank or some other fitting on a mezger motor. The only trouble is where to actually put an oil cooler on a mezger car.

So what you need to figure out is how the 9A1 routes oil and where you can plumb off of it to run some sort of external oil cooler. I know nothing about those motors, but it would be an easy deal on a 997.1.

Yeah exactly. I don't see many people with upgraded cooling solutions for the 9A1 engines. These .2 Turbo/S cars are not a true dry sump like the older Metzger engines. They also don't have the dry sumps of the 9A1 GT3/RS's.

I found an upgraded oil sump that holds more oil. http://lnengineering.com/products/ot...1-engines.html

It's freakin expensive for an oil pan. It does hold 2.5 more quarts of oil. From my experience on other platforms with these products, they make oil temps harder to rise but also harder to fall. It'll just take longer for me to get the oil temps up to 120+ degrees Celcius (260-270F ish) but once it gets there it's also harder to fall.

Usually these oil sumps do help when you run higher G's in the corners. Like if I ran slicks or something.

The proper way to do it is to actually cool the oil somehow.

Ultimately all you need to do is route the scavenged oil through a pump and into a cooler of some sort. I am vastly oversimplifying this, but lots of wet sump cars have oil coolers. Sometimes its as easy as pumping oil out of the oil pan into a radiator type cooler.

-Pulling the condensers off will get you -20 degrees f
-Assume you already have a big center rad? If not, you need one. Good for another 5-10f

changster123

I don't have a big center radiator. Does anyone make one for the 997.2? I see 997.1's use these.

When you say pulling the condensers... you mean the AC condenser? Like lose AC? That's not an option!! haha.

changster123

Also the 997 Turbo/S's all have 3 radiators OEM I believe. The center radiator should be OEM.

thekid96

No center rad on turbos. I would start there, I think I have GT2rs which is the biggest one that will fit up there.
If you can't remove the condensers you can do a bigger version of the OEM oil cooler. Probably get you a few degrees.

changster123

Great thanks. Good suggestions.

My 7.1 turbo certainly has a center radiator, i cant imagine they would remove that on the 7.2

thekid96

You're probably right, I just missed it when I pulled the front bumper off

Are both radiator fans working properly? Do they both come on at the same time and do they both blow about the same volume and temperature of air?

Maybe you need to take the high oil temperature as a sign it is time to draw the current track session to an end, take a cool down lap then bring the car in to the pits and let the engine idle a while until the oil temperature is more reasonable.

Go with a cooler over, or at least before adding, a bigger pan.

Just increasing the pan size will buy you a bit of time before everything is hot again, which may be enough for short track sessions. However, if it's not, you now have more hot oil with no way to cool it.

I'd also check the radiators for any debris/obstructions. They tend to vacuum up loose vegetation. But that's really more about water temp than oil temp, though they obviously both relate to engine temp.

changster123

Sorry what's a cooler over?

Also how much does debris make a difference you think? I did look at my radiators and for sure there are a lot of rocks etc.
