He mentioned a few pages back it weighed in at 28 lbs. Anyone have weights handy on Wagner, etc?



This is off Wagner site.

Just an FYI, though interesting, you can't use an infrared thermometer to measure air temps. It needs a surface to catch the emitting radiation, or which air emits too little to be detected by the thermometer.

You need a thermocouple type sensor.
Something along the lines of this.

The current test is basically showcasing how well aluminum is at dissipating heat, of which it is very good at it :). (It's why we use it for heatsinks in computers and electronics).

The Chinese guys are building nice intercoolers too: I bought the BIG CORE version - so tell them to ship the big core version only (because there are also smaller versions):

...what.... if I point my IR gun at my AC vents it goes from like 80 to the 40's? :confused:

May be. But, once I stopped blowing air into the inlet the outlet temps started to rise without the cooled down air blowing through it. So technically even though I was measuring surface temp of the inside of the outlet it still showed the obvious benefits of a big volume bar and plate heat sink. Once I pop my stock IC off I will repeat same test. Easy enough to do. :).

The heat sink that will absorb a lot of heat from both AC condensor and radiator. The primary function of the IC is to cool the air moving within the IC (internal) by air moving thru the bar and plates (external)
It's ability to dissipating heat without the external moving air thru is very limited due to its location.

Absolutely. If it was a front mount it would not need to be as big volume wise. It needs air to be pushed through it to do it's job. Even though sandwiched it's not going to see a ton of outside air moving past it where it sits.

Actually, a lot of outside air is moving thru the three. When I was installing the IC, I saw a lot of dust, small debris, etc were in between those. If dust and other small things can pass thru, that means a lot of air is going thru them. Two fans also help to pull the air thru as well. Otherwise, the radiator which sits way behind all the stuff will get overheated.

At highway speeds yes air is moving for sure. That is what those plastic air diverters are for on both sides of the sandwich. My point was it's not sitting off front of the car taking direct air like a true front mount. :).

It's measuring the temperature of the surface you are pointing the IR at. It can only measure surface temps, not air temps.

Little article on how the thermometer works.
http://blog.thermoworks.com/2017/02/how-to-use-an-infrared-thermometer/

If you want to study the intercoolers, you need thermocouple sensors, and/or some sort of logging system (such as Cobb's AP) to actually look at Intake air temps. (and read the cars sensor directly).

You'd get a similar result just heating up the side of a hunk of aluminum and using the IR thermo.
