So far it only gets up to a max of 92F which I would think the battery should handle fairly ok. Relocating it, or just venting it to the fender and sealing on the inside might work. Not a large consern currently since the battery came with the car and has lived its life already (5+ years).
I'm thinking about going for a tiny mirror that I was told autozone has from another ecomodder for the passenger's side. Not sure about the driver side, I drive at night a lot so being able to adjust it would be a large help (it is electric).
Most people I talk to are completely shocked at my mileage and I have been pushing ecomodder.com and what they can do help their own mileage. When people see results, they want part of it. My dad talks about making a grill block for his car now, guy at work claims I can mod his car for better mpg (not sure if he is joking or not). Another guy I work with is looking for a better base car to start with, then going to aero mod it some. Spreading like wildfire
. Once I get 50mpg+ I'll be throwing one of them "I get xxMPG" and a ecomodder.com sticker on the back. Might try to copy an idea that was for the anal probe about being a "MPG test car, please pass".
Can't wait for the 50mpg+ tanks with the help of spring/summer and more aero mods, wonder if I'll ever be able to join the 60mpg club with out a boat tail.
