There are mountains between my house and Mother's. If I left by sunrise, I could maintain 55 MPH up a good incline, but that was not a solution. I started this thread:
http://ecomodder.com/forum/showthrea...fan-32260.html, but there is a great deal that I need to do before working on that, like learning what all of those words mean, and understanding how they were used together. Also, being unemployed, with a rapidly-dwindling bank account, I am focusing far more on obtaining an income than spending money that I do not have.
So, I measured the back of the vent, and cut a hole to fit. I am not sure why I did not cut the bottom. Somehow, I thought that enough air would get through, but it only tilted in about two inches, so I thought that I would be creating an aerodynamic mess. I folded it under as you see:
but I need to put in three more sides, and I still need to make it rigid. I have plenty more of the rolled plastic, plus a couple of sheets that I purchased two years ago. I plan on cutting pieces to create a box, that way I do not create an aerodynamic mess inside.
I have had reservations regarding the vent, but going up one hill, my engine still started warming too much. Hopefully, closing the box will be adequate, although I am also supposed to prevent air from flowing past the radiator, so that would theoretically make another difference.
If this hole is not always large enough, then I cannot use the vent, because it would only permit roughly half of the air flow.
