I want some structural advice on this.
Yes the metal is rusty blah blah will be cleaned up.
Anyways, I cut out the wheel well hump, I did not cut out everything, just the hump impeding the way of making the metal flat.
Now, this is 16g steel. I am going to tack weld it in and use self tapping screws to fasten it down just to be extra sturdy.
My main concern, this tank is a 15 gal, when it is full it will weigh 129.9 pounds not including the cell.
Should I brace this from the bottom? My main reasoning against this is to sucessfully do it I will have to cut out almost all the trunk metal to brace across from the frame rails in the back, that being said, I do not know if it is worth it to risk a faulty weld causing my cell to drop, as opposed to having the remaining metal from the trunk hold it in if anything were to happen.
If the g-forces from an awd launch (probably 1.2) will cause too much flextural stress on the metal, it would break the welds, but still be safe in the back (just not properly mounted). I did not study fluid mechanics so I have no idea how much extra force a G would cause on 15 gallons of liquid moving laterally.
(Not even sure if it would be compressive stress, or tensile tress along with flextural)
I am going to bolt the brackets of the cell onto the 16gauge. Any advice?
Sorry for rambling.
