No, actually the Nitrous Oxide and high temperatures form an electrolytic reaction that chews the head gasket molecules at a time! That coupled with radiation from solar winds on the solstice under a full moon, man, those gaskets don't stand a chance.

----Just kidding, but really, I have some hairs that need splitting.

You may not have had any headgaskets blow, but I have never met a VW that didn't seep fluids from every seal it had.

What would cause noise that soundes like piston slap when I inject water/methanol?
My water/meth injection adds 3-4 psi at full boost and is ver addictive, but I am concerned about the noise it is making. Could the engine be detonating/preigniting? or is it just making more noise because it is working harder?

Yep - it sounds like diesel "knock" to me. It is possible, but usually only on concentrations of methanol that are around 70% or more. Like the others said - try running straight water to see what happens. Similar results can happen with the atomization is poor. Large droplets won't be carried uniformly or distributed correctly, nor will they be completely vaporized (apparently, haven't stuck my head in the chamber to watch).

Personally, I don't recommend any fluid through the turbo, as over time, it can erode the impellor. Not arguing with the results others have had, just posting my opinion. Can't wait to get my TD built and set up with a system.

here is a cool DIY site for water/meth ideas

Good for some ideas, yes, and this isn't the place to debate types of systems, but atomization is crucial and that involves nozzle design and the pressure of the pump. You can get measurable benefits with home-made ingenuity for sure, similar in technology to the systems made in the 30s-50s, but the amount of increase you can get with a modern proportional delivery system is much, much greater.
