I have read all the posts (from searches) and I am wondering, is it a problem running a battery without a battery box? Are the "fumes" put off from a battery damaging to the car body? Is the smell a problem? I am in an engineering mode. I want to meet the NHRA specs for a holdown (3/8 holdown through the floor)and I want to use a box. I am having a problem trying to develop a method to use both and still have the ease of removing teh battery without to much hassle. Any ideas would be appreciated.
