I think this was a pretty decent bench experiment. I think what we learnt is that the larger the intercooler with direct flow actually works better in addition to the fact that the eBay version probably hold more water in the cooler itself which the air has to even hotter in order to heat. In comparison to the cylindrical version which although has higher air flow, had less water in the system in order to move the heat. This resulted in the temps being much higher. I don’t think it quality that won today. It was definitely quantity and volume. Well done and thank you for the content.

Only problem I see with the test is that the eBay intercooler was only half full of water due to inlet and outlet fitting location. To fully fill the fluid portion of the intercooler, the supply fitting should be at the bottom and the return fitting up at the top. Without doing that, the top half of the core wasn’t even cooling the hot air.

Great experiment that has proved that the cheaper one works well. My concern now is the pressure drop of the charged air. You mentioned that there was a better flow from the tube cooler..As you have a water to air rad with fans it sound like even if the tube cooler isn't so efficient the rad + fans would cool it sufficiently. I would be concerned about choking the charged air causing a pressure drop.

The ebay items cross sectional area of the core is about 5 times bigger between the 2 coolers. For both water volume and air volume. Air 75mm inlet = 4417square mm, spreading out to 300mm by 75mm = 22500 square mm. The ebay cooler would hold about 1.2litres of water. The other cooler Air 75mm inlet = 4417sqare mm right through the length. Water would be about 550ml.

cooling vs flow. A larger cross flow will allow more surface area and a slower air speed thus a better cooling effect.

It’s simples the avt is a straight laminar flow of air there’s nothing to delay its passage over the cooling surface on the avt so you will get a high flow of air down side it’s not cooling the charge, the cheap eBay one has a more diruptive design as the air try’s to bend it slows down plus it has an increased area to desipate the heat over so thermodynamics come into play, in the real world you want to not impede the airflow but also cool the charge down unless you carry a fridge cooling system or peltierheat exchange it’s going to be hard to do both.
@Antman4656

You are correct but does this matter as much for a turbod car as the air is pressurised through the intercooler so must negate some of the effect of changing direction and I'm guessing will gain more power in cooling than a small restriction. But as his test does not use pressurised air you are correct that the results are not conclusive and the small restriction would play a huge part in cooling. If he used pressurised charge air the results may be totally different.

From the looks of it, the air flow characteristics of the Ebay cooler should take more of a diagonal path from the inlet to the outlet instead of directly across. If that's the case, then the "cooled" surface area inside should be a similar amount. The ebay one looks to add turbulence to the flow though which could protect the thermocouple from seeing the full blast of heat from the gun. I think when you start to turn the pressure up, more heated air will see the thermocouple and the temp difference will even out. I'd run the same boost with each and test on the road with a IAT reading

The thing that you need to be measuring is the TIME per degree, (which you are sorta doing), but your air flow is barely at idle levels, there's a massive increase in flow under full boost. The winner can be gleened by simply the weight difference between the two coolers, (that's aluminum PLUS water weight), this will determine the rate of temperature rise every time. Also, the total weight of the circulating water, and surface area and air flow through the heat exchanger, (radiator), plus the weight of aluminum in the heat exchanger. Water can absorb a tremendous amount of heat, the more you have in the system the slower the temperature will increase, OR, decrease.

There is a direct correlation in flow rate and pressure. A big pressure number does not mean a good flow rate of air into the engine. Think of how to do more with less. As in less restrictive intercoolers. Less restriction means more flow and low heat as well as more horse power per pound of pressure.

Assuming your heat gun can handle it, do a 5 minute test or whatever so that you can see at what point the temperature stays steady on both the charge coolers. While one will cool more, would be nice to know how much cooling you got with each cooler. What you’re charge cooler options are will depend on your car. I have a 95 trans am with a rear mounted turbo system, already had an air/air intercooler mounted in front. Car isn’t running right now, but I have considered putting a “Barrel type” cool charger (it would fit) on the pipe that runs underneath my car. That would cool air before it even hit my air/air intercooler. I have seen “Barrel Type” Cool Chargers on E Bay for 100 to 130 USD.. If I go with the charge cooler, may consider upgrading it to an “inter chiller” where instead of running coolant, I would use the A/C system, this potentially would allow more temperature reductions compared to water.

Testing a cheap cooler with 2-3 times the thermal mass isn't fair. Something people don't think about with a cheap square intercooler is if it fails and you have large amount of water enter the engine it will cost a lot more. Round is much better at containing higher boost levels, and higher quality means less likely for leaks. You might have a very thin film of brazing on the cheap intercooler and one day it breaks and you pump a cylinder full of coolant, see how cheap it is then.

I am not a boffin on this - but I think the big thing is you have left out the manifold pressure - you ( I assume) have tested the ability of the unit to transfer heat only - and we know that the issue with intercoolers or the need for intercoolers is a function of the compression of the intake charge. And there is a horrid set of maths -that relate to P=MST and P1V1= P2V2. so without the manifold pressure( push back if you will) the test you have undertaken is not at all representative of actual on vehicle conditions. We have little or no latent heat, we have little or no heat soak ( which is actually the cause of most of the pain in the first instance) and we have no pressure in the against the discharge of the heated air. Again effecting the ability to transfer heat. Curiously the better quality unit gets the water much hotter much quicker - which when you think about it speaks to the efficiency of it to conduct the heat away. where as the el cheapo unit seems not to follow the laws of physics. Quite sure the bright guy in my class room - the one that used to each the clag glue would be able to explain it too us. In the meantime - I humbly suggest the abscence of any resistance (pressure) detracts from the actual experiment.

I think these tests are inaccurate. 2 reasons, the heat gun is about 2 inches from the water line and on thebay one its about 5 inches with a bend in between, also you are heating up the charge temp sensor much closer and more than you are on the eBay one because it is receiving straight hot air contact. And probably the most important factor that was missed was airflow, which one flows better. I think bench tests are often inaccurate, the best kind of test is putting sensors on the car and seeing real world results.

Surface area. Bigger is better with intercoolers

The avt barrel cooler is tape insulated (?) - which is great for engine bay but not for this test. The cheap one is not insulated and has a large thermal contact area with the bench. I don't understand how the coolers can be above the open header tank. Presume you bled the coolers in particular the avg one as the outlets on the side. I think flow is the main issue so a low flow hot air gun through the cheapo one I would expect to perform better due to the thermal path that has to be followed. Not sure what water pump you are using but my Bosch pump would squirt water everywhere with that set up (open tank and no clips on hose). What are the so called ratings for each cooler - the barrel one looks to be power rated lower? I think the cheapo one has quite poor cooling internals (flat weave) whereas the avg one has proper finned fins for a greater surface area. I appreciate your efforts.

Wouldn't matter if the larger one was insulated. The results would be the same. The more exoensive unit is a smaller packahe and what it sacrifices jn sizes shows up in poor efficiency. The onlu difference wiuld be the larger unit will yield about 1 lb of boost drio where the smaller one will only be around .2. Who cares if it doesn't do what it is designed to do!

the results are what i expected when i started watching the video, one has twice the cooling area of the other, was a bit obvious, you can also do a pressure drop test if you want, but in terms of cooling capacity i think its done

I don't think it's a particularly good test, the test condition does not reflect the operating environment, all it shows is a large heat sink Vs a smaller one, those temperatures may not necessarily reflect how it will perform in a car under a closed bonnet for hours, and if the temperatures were good enough on the smaller one for detonation to not be an issue, then would the flow sacrifice be worth it?

mikegt4dude I am still not convinced the cheap one will be better under real world conditions. But I will try it on the car to see. I will see if there is a air flow restriction as my boost controller works on wastgate percentage rather than target boost pressure. I will see what it boosts at

Have you got wideband with data acquisition? You should see your tune go rich with reduced airflow and lean with increased, inlet, outlet and ambient (engine bay) temp sensors would be ideal.

mikegt4dude yeah, wideband and inlet(throttle body) temps are plumbed into ECU, so can log everything. See what it does

I think the experiment doesn't take into consideration that the air from a turbo is compressed. What in my opinion it does show is pressure loss, just indirectly. I've redone my factory intercooler design and because my turbo is small, I felt it's best to keep psi losses to a minimum. The barrel type would be best for my application, however someone with a turbo that makes higher boost might benefit from the other design. I feel your experiment shows that the distance from inlet to outlet on the coolers are different which would make the temperature difference. I liked the experiment however, and your willingness to take the time to share it with the world.

Simple. The Ebay one has more surface area.

Hey Spyder i know this was done long ago, but just saw it i like your channel it'd be interesting to test pressure/weld quality limits on both (controlled/safe of course) wouldn't it? it would totally suck for a fracture to put water into your motor in high boost pressure situations hahaha

The avt one is tiny compared to that ebay one though. Need to have two with similar sized cores. What size was the avt one?
