best place to install a water-meth system in a w116 ... more specifically, a 1979 300 SD Turbo Diesel?

Snow Performance sells a water-methanol kit that should fit tidily in the engine bay.

Anyone who has one, your thoughts?

I don't have one,but when I was running wvo,I almost bought one.I wanted to use it to pervent coking of the rings.I mostly high performance my gas engine,and if I were turbocharging you'd bet I'd have one.

Are you running a lot more fuel and a lot more boost?

I used a devils's own system on my w123, pump on the passenger fender well, nozzle going straight into that flat spot on the turbo outlet so it has plenty of time to atomize the mixture

Sarsaparilla, what were the performance gains if any? Lowering EGTs is nice ... Snow Performance said I could get +30hp ... really?
