Anybody familiar with the water to air intercooler on our OBS trucks? CP addict has one available. Is this a better alternative to the air to air?

Looks pretty cool. Was bummed to see it's specifically designed only for a stock style turbo setup. They acknowledge T4s exist in the video but may as well folks to kick rocks and figure it out themselves
Might be interested if they offer a builder version, without the intake piping. Maybe offer options since they dont mention plenum pipe size, but some folks have different plenum inlets too.
Hopefully they evolve this into a more versatile kit.
I wonder what type of results are there in comparison to the air to air kit? Seems to a lot less work then installing a radiator unit.
What about having coolant so close to your intake? Kinda scary to think that you could be flooding you intake with coolant/water if that cooler failed and released coolant into your intake but I guess no difference if you had injector cups cracked?
Same idea as the stock oil coolers on our trucks, just air instead of oil.
It still has a smallish radiator for the fluid that mounts up front. I didn't look to see if it ties into the existing cooling system or if it has its own pump.
It needs to be separate from the engine coolant system. The 6.7s have their own separate system for the intercooler. I see no mention of a pump to circulate the coolant. Without its own separate cooling system, IATs will never be lower than engine coolant temp. Seems like it'll be an interwarmer.
The packaging is cool, but one of their selling points is that you won't have to worry about airflow at low speeds. The system still relies on air moving thru the front mounted cooler to cool the system, just like an air to air intercooler. The only way this could possibly improve low speed performance is by absorbing more heat before the system heat soaks.
The only advantage i see is packaging. It is a pretty neat install. If it's using engine coolant, performance gains will be questionable. If it has its own system/pump, it's going to add complication over air to air.
Looking at what is supplied with the kit (hose, T-fittings, and "mini-radiator"), my guess is that this pulls engine coolant, passes it through the "mini-radiator", and then to the inter-cooler. So you would be cooling the air to below engine temps, but I wonder how much. I also call BS on pulling a HPOP without removing the cooler; nobody in their right mind is doing that job without moving it. Especially since it looks super easy to move to the side. I would love to see some real boost and egt numbers for this compared to the standard air-to-air.
Someone here has one. I can’t remember who it is. I will see if I can find their post about it. As I remember, it does use the engine coolant as he was asking about hoses.
