The inlet/outlet temps would be cool. I hate to keep buying stuff for a test. If the bucket keeps getting warmer, I can assume the rad is too small. But I’m a little surprised the EGT gets to 1000 before the water temp gets up. I’m thinking even if I upsize that cooler to make the water cold, it still will be running 1000 at 60. I guess the impressive aero dynamics plats a part in the power demands.
Fill the bucket with ice? Still need (IMO) to know incoming and outgoing temps to the intercooler for air and water to learn if the issue is that the intercooler is too small (air temps never drop), or if the intercooler radiator is too small (air temps drop until the delta-t between air and water gets too small).
I like the ice idea. I’m kind of a anti-Amazon person, but I guess I could get my wife to order it.
They are on fleabay too, I was just showing some examples:
I'm no expert, but it shouldn't be able to with a normal turbo setup. One could argue that it could be achieved by playing games with the turbo sizing and efficiency maps, but it would be very intentional at that point. But it should reduce in temperature if it did.
From the sound of it, the rad isn't keeping up. As said by others, sensors, icing the bucket, or replacing the bucket with a large rad should point to the culprit.
Type of fuel doesn't change the physics of it. Still an air pump, still going to gain efficiency with lower IATs.
You're getting a bit into the weeds with specifics. How much is "too much" is different for every person and every system. Lowering the intake temps is always an advantage. If you keep going with your testing and find that you're able to get your temps lowered by changing your setup a bit that's all that matters. The testing here is to verify whether you have room for improvement, not to see how it is compared to other stuff. Keep on keeping on.

Diesel EGT Data with an Interchiller – Fi Interchillers Online Store
Over the years we have had our interchiller installed on many diesel applications, we just haven’t had the time to tell you about it…they work great!!! Below we will get into the juicy EGT data you are all wanting to see, but first lets go over how this all works. Firstly as we all know…or […]

Do those work under sustained load or is it one of those "takes more energy to run the compressor than the system pulls out of the charge air but it still helps you in the 1/4mi" type deal?Oh fuck yeah. I never thought of tapping into your existing AC system, that's bad ass. Check out this install link:

That’s what I was thinking. If you read that link, they point out how the water to air doesn’t block the regular radiator, but don’t mention where they put the intercooler radiator. They act like there isn’t one, but even if it’s using AC there would have to be a condenser. I read another article about this idea and they said it was not practical. I notice the company is out of Australia. Lots of fun trying to get your money back when it doesn’t work.
Pesky thermodynamic laws sure do get in the way of good ideas
Up date,
So I decided to do some testing on my intercooler in effort to lower EGTs. First I drove down a local road to get a baseline EGT. I was going about 60 mph and the EGT went to around 1000 for a short time and then slowly backed off to about 900. I did this with a cold truck. The course was 1 mile of dirt road at 30 mph and 3 miles out and back on a two lane black top. When I turned around and excellerated, it went back up to a 1000 and then down again as I just cruised. It never went below 800 and the water temp was up to 210 at the end of the run.
I removed the cork gasket in my intake system. I feel that cork is not appropriate, but the gasket looked fine and I don’t believe it was leaking any boost.
I made a new gasket from that blue material you see.
Next I cleaned out a five gallon bucket and drilled a couple holes. That and some heater hose gave me my test kit.
I had installed some cut offs on the intercooler set up last time I worked on it. They made it easy to do this without draining the whole radiator.
Then it was a simple job to unhook the hose from the suction side and return side of the pump and plumb the five gallon bucket in and separating the whole system from the radiator. This picture shows the setup in the back of the truck.
Obviously, I spilled a ton of water getting the system primed and pumping. I also got a mouth ful of coolant. I can say I would rather drink gas than coolant. This was very difficult and I wonder if it was ever primed before. That pump loses its prime in a NY minute.
On to the test. Again, the truck was dead cold and the temp outside was pretty close to the same as the baseline. I put about 4-5 gallons in the bucket. I drove down the dirt road slow so I didn’t upset the unsecured bucket. At the end I stopped and checked that it was fine.
I headed out on the black top briskly to 60 mph. The EGT went to 1000 again at 17-18 inches of boost. I stumped the pedal for a brief period and got the EGT up to 1300. Let it slow back to 60 and the temp went back to 800-900 just as before. I turned around and repeated the return trip. When I got back to the dirt road I noted the water temp was 200-210.
Before driving back the mile to my house, I climbed in the bed and felt the bucket. To my surprise, it was hot as hell. I’m not saying you couldn’t touch it, but you weren’t going to lift the bucket with your wrists “Kung Fu” style. (for You young kids that don’t know what that means, it was hot) I crawled under the truck and felt the intercooler radiator. It was blowing warm air out. I drove back to the house and got the lazar temp gun out. The bucket was 120 degrees, but it felt like it cooled some from earlier. (Not any boost heat on the dirt road)
So now what to make of this?
Hottest part should be water out of the intercooler and this could be getting near the hot air in temperature. That's all kinda normal.
