Anyone look at the output pressures of the CAC on the backside of the cooler? According to the video, lower pressure should improve cooling.

I picked up a set of gauges (several) over the weekend and will be doing some work on the ram to improve its mpg's for daily driving (currently easily can get into the 23's per tank on the 7000 lb tank). I picked up the book promoted in the video and am eventually going to take a look at the CAC output pressures once I gain some expertise with the gauges...

 

One simple check...
Look into the inlet side of the radiator.
Make sure that there is some sort (rounded or pointed) flow directors to "smoothly" direct the airflow into the cooling tubes.

The radiators with a "flat" section between the tubes will cause turbulence as the air hits the "flat" areas, vs a flow director that "smoothly" directs the airflow into the tubes.
Ever seen an airplane wing with a flat face ? Same thing here..!

Just like the standard factory, and the GP cooler.

Yeah I've seen pics of the inside of the CAC and the design feature makes total sense. But, I'm talking about the backside of the CAC and the pressure around the intake, fuel rail etc... that pressure vs the input side from the hood. The cooler's efficiency could potentially be improved depending on what the data shows. Low pressure on the backside would be better.

 

Yep, I also believe thats how the cooling works on the radiator pack. Pressure differences on the front of the car vs in the engine bay/below your car, which pulls the air through the radiator.

[edit]
When I had my Seat Leon 1.8T 20VT, I performed a small modification when it had the SMIC (Side Mount Intercooler), by adding a vent behind it for added push/pull. Never did any measurements, but I tend to believe it helped somewhat In the end I installed a FMIC.

Mod was inspired by the Audi TT 1.8T, which had vents there by default to aid in cooling
