So I made a short post before but it got moved to general. To continue in a more N54 related way, I will say that I don't know a lot about dealing with refrigerants and know only a small bit about Air to Water Intercoolers.
Here is my inspiration:
So a basic A2W kit would include:
A2W Charge Cooler
Water Pump
Water Lines
Custom Charge Piping
A2W Heat Exchanger
Electrical Wires, Switch / Integration
Now if we wanted to make this inline with the existing A2A intercooler, it would have to go most likely after the FMIC and be mounted in some of the free space or inline where the chargepipe is with a bullet style A2W intercooler(Charge cooler). I'm curious what type of extra restriction this would pose on the system and what kind of extra pressure drop we would see. From the units I've looked at, they approximate about 1-1.5 PSI drop.
In Addition to putting this inline with the FMIC, we would need an A2W Heat exchanger to shed off the heat absorbed from the A2W Charge cooler, most likely mounted in front of the FMIC, in a air duct on the Driver side, or a vertically stacked FMIC/Heat Exchanger setup.
Lastly, if we decided to use the Air conditioner's refrigerant to super cool the A2w intercooler, we would need a Evaporator coil/core to cool the water.
The combinations here could be:
1) A2W Heat Exchanger + A2W Intercooler - This eliminates the A2A FMIC
2) A2A Intercooler + A2W Heat Exchanger + A2W Intercooler - This retains the FMIC and adds normal A2W Intercooler and Heat Exchanger
3) A2A Intercooler + A2W Intercooler + R2W Evaporator (Refrigerant to Water) - A2A IC is required when the AC is off to cool the intake charge
4) A2A Intercooler +A2W Intercooler + A2W Heat Exchanger + R2W Evaporator -This is the most complicated setup of all of them and the one I've been thinking about the most.
Questions to solve:
1) How much extra refrigerant plumbing would be added and therefore how much extra refrigerant would be necessary in the system?
2) How much additional stress does this add to the current Refrigerant system with each setup
3) Does this additional stress put our compressor at risk by not being able to keep up and cool the refrigerant in the condenser and potentially sending more hot refrigerant back to the compressor?
4) What kind of extra condensation would this produce and how to manage it
5) What type of electrical is going to be required with each setup to run the A2W intercooler separately from the Cabin AC and how to turn on and off the water pump depending on if there is an A2A intercooler to cool the charge if it happens to be off
Please comment. Just searching through ebay these parts are not all that expensive.
