Well I ordered some stainless steel louvered vents (cheap) and a 3000 cfm puller fan ($100 Summit) a couple days ago.

Yesterday it was 85 degrees here. I was driving across town and it was over 210 getting my destination. It was probably 75 or so on the way back and temp gauge dropped to 195.

I'll let you guys know how it turns out after I install the vents and then the fan.
