Ok, so I was thinking about building a corroplast belly pan on my sl2 after reading about one another saturn owner built; not only because I'd like to improve my mpg, but because the factory air damn got ripped off by some road debris, now my car feels rather floaty and less safe to drive at highway speeds.
Most of my miles are highway miles (I live right by the on ramp to the main corridor through wichita, and work right by the off ramp 10 miles down the road or so) so I really figure I'd see an mpg improvement as well as stability from a full belly pan.
My concern is engine compartment cooling. I figure a lot of heat actually gets pulled out under the car, so I'd like to force cool it somehow. This got me thinking. I figure I could put two 12v computer fans near the top of my engine bay (heat rises, right?) duct the airflow down with dryer-vent piping and flushmount a dryer vent (like the kind with the flaps that close with no airflow) into the corroplast.
I figure the flaps on the vents would close at high speeds due to terminal velocity, but I could build a thermostat that would activate the fans once the engine bay reached a certain temperature, forcing the flaps open and venting the engine bay. Otherwise, the fans could run while idling or at low speeds, to vent the bay while not being aerodynamically inhibitive.
Anyone heard of anything like this, or have any thoughts?
Also, Hi. I read this forum a lot but this would be my first post
