Yes, I've got a DeWitt radiator with Spal fans to install, and I'm presuming that may help a little bit to pull more air through the intercooler. If that doesn't help much (as I'm presuming), then WM appears to be about the next step to reduce IATs. I don't desire to maintain a tank, but that appears to be what I signed up for.
Not knowing WM stuff, would I be able to add WM in a minimal way, meaning a smaller versus a larger nozzle, just to reduce IATs? And, just with that in mine, could/should I run lower concentrations away from 50/50 or 100% meth? Will attempting to lower IATs (with minimal effort) require adjustment to my tune (changing fueling)? I'd just like to have a little something that lowers IATs, to keep them below 200*F - that's all.

If your only goal is lowering IAT then Distilled Water is your best option because it has ability to absorb heat and will not affect the fueling, but will take more timing or more boost.
If you need more octane then by all means run Straight meth but do not add timing just add boost and tune the meth system to only lower the Lambda from .78 to .74 let it be a little rich it won't hurt power.
