Why not do it in the trunk if you're worried about it? I mounted my nitrous tank (when I was still on nitrous), right after little fake harness bar thing. When you pull the plastics off, you'll see two pieces of foam that you can remove.

The only other thing you have to do is relocate the antennae for the smart key. The harness is long enough for you to just remove it and flip it over.

Also, have you ever looked at the location of the wiper tank? It's about a gallon, and in front of the tire, and the headers/turbo manifolds are covered by the chassis itself. I do suppose you're right, that there is a chance that it could potentially catch fire, but just don't know the likelihood of it.

Better safe than sorry I suppose. I've ran my meth this way for years since it's compact, and one thing people forget about mounting the tank and pump in the back is that you do LOSE pressure in the line.

So realistically speaking, I probably will go down to a 70/30 mix, for safety reasons, fortunately enough I haven't tuned for this mix, so it's not that huge of a deal.
