I run meth in my supercharged 408. I am using a kit from AIS. A few year ago I was dyno testing the engine and there was a 70 HP difference when meth was used. I couldn't believe it. I actually bought the kit because it was easier to install than an intercooler. The added octane is also a big plus considering windshield washer fluid costs much less than race fuel.
