So typically I’ve seen that in performance modifications, diesel engines will use an air to water inter cooler system.

To increase the gain, ice is placed in the water reservoir to further cool the intake air. The problem is, this is a limited application as the ice must be replenished quite often.

To extend the duration of these gains I have a few ideas:

1. A similar setup to the dodge demon Air-Grabber system, diverting the AC system into the intake to further cool the intake air temperature (45 degrees)

2. Using a standard water to air inter cooler you drop the intake temp by 30-50 degrees. Adding ice drops it by 50-80 degrees.

3. My idea is to have a cooler similar to the Air-grabber, but instead it auto diverts some of the AC system as needed (Any extra percentage not needed to cool the cabin ie 90% to cabin 10% to engine) up to full system utilization if the cabin is not being cooled, the evaporator core (to the effect of the air-grabber) is instead placed in the air to water tank, and a fluid is pumped through it, cooling it instead of the ice.

Diesel engines from my understanding are more efficient due to low end torque and the AC system doesn’t have as much impact on the load and fuel economy as it would on a gasoline engine. Im curious as to what effect this could have on power and fuel economy over a longer duration, then say down a drag strip once with ice. 🙂 thanks in advance 🙏🏻
