Question
With the airflow on your summer intake port: a few questions (I'm really considering this).
The hole: does air enter the hole, or is it a port to exhaust the rad-A/C heat, or both? My concern is the flow of air. So, the air enters the port, but where does the air exit? As you mentioned, the engine is nearly sealed. I understand that around the hood the gap may provide some relief, but where does the incoming air go in bulk? Otherwise the pressure builds, and nothing happens, so the hole is basically as good as a flat piece of Cloroplast. I'm imagining a small opening, where the hood closes, near the wipers. It may not require cutting of sheetmetal, but rather manipulation of the rubber gasketing or running it into the screened area where water drains from the windshield. A fancy version could have a a one way valve (perhaps a rubber flapper like the the positive ventilation valve behind the trunk paneling to keep fresh air moving through the car, but keeps the rain/sand/dust out.) Just a thought about the whole heat rises thing.
