You mentioned doing a test below, but then said you didn’t. Have you measured the differential at speed? My calculations about heat exchange time related to air speed wasn’t anecdotal, and it, along with the experiments, were more about countering theory with theory. There is just as much theory to suggest it doesn’t make a difference as there is theory to suggest it does.



I mentioned brake ducts because that space is often used for brake ducting in race applications. A SMIC or oil cooler can also go there of course. Every setup is different for prioritizing different things. My point is that the OP appeared to want to have space for everything so nothing is stacked. Thus, he can move the oil cooler to the side only to move the brake ducts to the middle, which may block the radiator or intercooler. The packaging of everything requires forethought and careful consideration if the car/application demands such considerations, which it seems his car will require, maybe; we don’t know. He has been mum about any specifics. Apparently, it is a secret.

I am confused by the bolded statement. I said I'd test it(air temp off the oil cooler) if I didn't just kill a thermocouple. I don't know what this " then said you didn't" refers to.

Here are all of my posts up to the one you quoted.

I think you would be surprised, it sheds quite a bit of heat. If I didn't just kill one of my thermocouples I'd test it on my NA car. Though to test it properly I would need to build a duct off the back of the oil cooler to prevent ambient air from mixing with it to get a better reading.

There are other ways to mount brake ducting without going through the fog light bezel. Not really an obstacle I would be concerned with.

Doesn't seem like it, seems like you are more intent on proving your point. Funny thing is, for most applications I agree with you I doubt most guys who have boosted street cars will care or would notice the difference.

The more I think about it, I don't know how useful it would be to your point. I could only measure the air temp coming off the cooler, I can't correlate it to IAT of an intercooled car since I'm not boosted. You could test your point yourself by logging oil temp, ambient, and IAT with and without an oil cooler. Though as I said, it is something I could test though the motivation to do it has dwindled quite a bit. Maybe I will mess around with it later in the year when I work on measuring oil temps and pressures in and out of the cooler. I think a big factor is how close the oil cooler is to the intercooler. The air coming through needs some time to diffuse as well as not radiating heat directly to the intercooler, or obstructing intercooler flow.

Your airspeed comment makes no sense. The oil cooler is an obstruction, the air moving through it is not going 65mph even if the car is. Makes all those numbers worthless. I am sure you could measure the airspeed into the oil cooler and exiting to figure out the pressure drop over the area to calculate the airflow through it, and then calculate the amount of BTU's that volume of air can carry away at that speed, but that sounds like wayyyyy to much work.

Brake ducts can be built and mounted however, even if the OP's car is a full on race car it is not going to be an issue no matter where the oil cooler or intercooler goes. Why mention it? Not an obstacle. You come across as only mentioning it when it suits your argument.

Reading the OP's previous posts, I am not sure I would be concerned with his usage. Especially if he is not commenting on it. Not a dig at him, he just seems new to the modding game with his previous threads and from the sounds of it doesn't track his car.
