So, while we’re waiting to see what GME (yolo) is gonna do, what wheels dija get

Ok, I've got to ask.
The chiller is essentially an A/C evaporator built into the intake manifold, used to drop IAT, correct?
If this is the case, then doesn't the condensation from the evaporator drip inside the intake manifold and into the engine?
I realize it is probably not enough to cause any harm. As a matter of fact I am a big proponent of dripping water into the intake once in a while to help clean the combustion chamber and get rid of carbon build up.
Anyway, I was just curious as I'm not terribly familiar with the chiller systems.

close kb, and im glad you asked
this is a few things going on. the a2w intercooler/intake, tank, pump, and the chiller. liquid (antifreeze in this case cause it gets down close/below the freezing point of water) circulates thru the entire thing, starting at the tank>pump> IC>chiller> back to tank.
the chiller simply cools the antifreeze similar to how a water cooler works, liquid (antifreeze) to liquid (refrigerant/freon) "brick", tied into the ac system
you would be correct that the temp difference between the air hitting the cooled intake would form some condensation inside, i am however sucking in 100+ degree air and compressing it causing the temp to rise even more, so the humidity in it is probably a lot lower than the ambient air. and whatever does form further cools the intake charge as it gets sucked in

That makes sense. The chiller cools the water/coolant in the A2W system instead of directly cooling the intake charge.
Thanks for the explanation, I learned something today.

i think we're about tapped out boys....
top row dark blue is injector duty cycle, rides 100-105% thru 2nd, come back down in 3rd. the white line in row 2 is the fuel pressure, where its at is fine i just have to worry about the injectors sticking wide open.
top row light blue is the intake temps, still quite a bit of rise on it 60-138*. i ordered the bmw pump, pierburg cwa400, going to see what i can do with mounting it. it is a lot of temp rise, manageable and to no fault of the intake - moving more water should help and i think im pushing this turbo past its efficiency range - boost is the purple line on the second row. boost controller is set pretty much right where i wanted it, just below 255kpa.
