As in not cold (down to -40°f/c is common winter for Montana, USA) and not hot as in Keep the IAT under 90° f @3% wasted fule. AIT between 60-90°f Costing Engine On through full throttle. Keeping the AiT =<ambient. It'll be summer MPGs in winter. Or hopefully an improvement.

From: frəm/Submit

Intake manifold: In automotive engineering, an inlet manifold or intake manifold (in American English) is the part of an engine that supplies the fuel/air mixture to the cylinder.
There is a difference between inlet IAT, pre-turbo IAT,post-turbo/pre-Inter Cooler IAT, post-Inter Cooler AIT, and intake manifold the one closest to the intake valve is the one that counts.
Could you use bold in future as it is easier for me to see than italics with my eyes.
Hope this helps.

Oil pan4 what were your setpoints open/close °f ?
Most of thease CARB air cleaners I've run across have been slow movers .5-3sec reaction times. Like a coolent thermostat when you test it on the stove. Is yours supper fast?

----I'm planning on using 2 snorkels or a custom hand fabricated system for the choking action youre speaking of under load. May end upsuing a damper door from an old A/C with this "brain".

Both of our engines are in excess of 350 cubic inches which is far exceeding the air flow capacity of a 2 inch diameter smooth tube ,and the corrugated flex hose is less. the hot-air side of this device is set up with1.25-2.5" most were 2" if memory serves.
My hot side needs as much flow as the cold. I am assuming that @-40° pulling Elk_Park_Pass I'll need it With a dT of 100°f.
