The mechanical thermostatic valve is mechanical and regulates the air to around 90°F.
The electric portion only reverts it to cold air.
You don't have to use the cold air.
I thought about restoring the OE thermostatic intake but I wanted something a little different.
Main difference with mine is I was never trying to flow full air flow through the WAI.
If I need power the CAI is opening.
Also I am going to be running 11:1 compression.
I will end up using 2 snorkels too.
If it gets so cold there why not just convert to an after cooler and just turn off the after cooler when it's really cold letting the turbo heat the air? While drawing air from under the hood.
That is what I was going to do when I thought I was moving to Montana or Wyoming.
Have you read the 5.9 stationary non intercooled application manual?
They recommend running cold air down to 25°F to freezing, then drawing air from inside the enclosure if operated below 25.
