roots are only about 40-60% adiabatic efficient, so thats were the heat comes from, just simply by displacing air. I was going to say an insulator plate isn't going to do much as you are trying to insulate one heat source from another with similar delta so really not much is going to happen, you need to cool the charge as it comes out of the blower and hopefully keeps cool for long enough before entering the combustion chamber. The insulator will help the intercooler core from external heat soaking thus leaving the intercooler coolant cold to do its job.

Yeah, I get that bit.

I guess well see when I get shocked by the AIT's from the MAT sensor in the LIM.....

Unless of course anybody is interested in getting rid of a W2A core I'd be happy to take it off your hands for the right price

you need more than a fish tank pump and motorbike rad, more like a cobra pump (google it) and a full sized 16mm radiator at least. Given the intercooler core isn't big, you want to give it its best chance by providing as much flow and radiator size as practically possible so that the core is always supplied with close to ambient coolant temps and at a fast rate! so its can't be saturated with heat on the first boot full of boost.

You'll be surprised how well an WTA intercooler works when suppied with cold water at an endless supply. On my mates supercharged jetski it has a WTA intercooler that is pumped with massive volumes of external water and the inlet temps are very hot, the outlet is stone cold like the water lol, I'd say its close to 100% efficient, technically more than as the water is colder than the hot air outside Unlimited ice water intercooler ftw!

Check out some of the FB pages for commodore bits, always someone wanting to sell parts cheap to get their next ice fix.

As for the temps, around 130-150 is pretty common for a mild-moderate M90

ahh, yep completely get it now, dont want the water to sit in the cooler for any length of time to soak the heat up, and not be effective, so big cooling area and lots of flow

yep!

When you are talking about keeping an engine at operating temp I do. When you are talking about maximum removal of heat for electronics I'll still go a peltier against a bling bling rad and blocks anyday. Horses for courses Vlad horses for courses

Laws of thermal dynamics universally applies regardless, so I would disagree on that as the original argument was about flow verse heat rejection in the radiator not about thermostats.

I agree laws of thermodynamics do apply regardless BUT this is an automotive forum and the thread is about automotive cooling systems. Engines run best at operating temp, cooling systems for automotive engines are designed to scrub heat in a controlled fashion from the engine and then the radiator. You cannot discuss one part without acknowledging the existence and purpose of the other. In a car radiators are a restriction and this is by design. As already mentioned they are designed to ensure the thermostat spends its time between just open to not fully open. If the radiator was not a restriction the thermostat would spend the vast majority of the time closed in order to keep the engine at operating temp this becomes a problem when, as already mentioned, cold water enters a hot engine as the thermostat opens to let cooler water through only to shut again when the water temp is below the thermostats designed temp range.

A PC is a totally different animal and does not require a controlled system, even though PCs do control fan rpm it is not a must to have controlled fans cause you can just run them at 12 volts (max rpm) if you want. PCs like running cool, overclockers build extremely efficient cooling systems to keep the CPU as cool as possible.

Like I have said horses for courses. You design cooling systems for PCs, automotive manufacturers design cooling systems for cars. You and I are just going to have to agree to disagree.

I don't do FB.......

Yeah, I wouldn't be surprised and in all honesty even a low boost M90 would probably benefit from some sort of IC system.
