No, there was another guy on the forum that did a meth port injection. The HPF manifold was a fuel rail port injection and if I'm not mistaken they are putting on the single turbo car they are working on, or have been working on for more than two years.

I can't find the one where they guy put meth nozzles on each port and used JB Weld. It looked cool, but after that you didn't hear much about it again because apparently it didn't work so well.
