So you are still regulated at 48 psi? I;m using a 05 pump and regulator with no adverse effects to street driving. My reasoning being to try to have more fuel available at wot. A/F is solid 12.6 at wot, but was before also. So I don't know if it helped. I just threw that out for info.

Let me ask a dumb question. Wtr/meth cools the inlet air charge, which adds density and the alcohol assists with the cooling and adds some fuel to add power. Simple enough and cheap enough to use on the street. On FI engines this allows low boost engines to run without precoolers. Now nitrous does all the same things in addition adding extra oxygen to enchance the burning of additional fuel but is not cheap or streetable. Why would you try to run the two systems together? Seems you would run a wtr/meth system on the street and then use nitrous at the strip.

Steady 50psi fuel pressure. Not sure what it is under full 10 psi boost..... Need a fuel gauge.

Exhaust temps go up with NOS and boost. W/M would help control that.

Exactly. Nothing on this planet is even close to absorbing heat like water can when vaporized.

Thanks for the information, I know with my tune I can get some knock and using wtr/meth eliminates it. So I'm sold on using it.

With nitrous it adds power but you also have to pull some timing to help with knock issues if you go a little crazy but with water/meth realistically you could ad the nitrous and leave timing alone and really gain all the potential power from it

I am buying a stage 2 water meth kit very soon and will be adding timing back in to the tune I would say upwards of 60 more hp possible with me current eng setup
