It's pretty tightly packaged in the 3.5 ecoboost engine bays, so are there any battery relocation options? Seems like relocating it to the trunk would free up a good chunk of real estate under the hood. Combine that with an intake like the MDesign and that's a ton of space you've freed up. We certainly have the trunk space to spare, lol. It also seems like it would be easier on the battery, since the trunk is so much less harsh of an environment. Any reason this isn't a more common mod? I'm not seeing a lot of downside.
