I finished installing my water/meth injection kit today (devils own). Its the basic kit with a nice pressure switch instead of the progressive. I set it to start spraying at 15psi (nervous lol). I just went to the other town and back and this is my experience so far. In the reseviour i used one bottle of heet which is like 99% meth and filled the rest up with distilled water. Its about a gallon resevoir, not sure what that makes the mix. So I took it out and was afraid to get on it for awhile, finally I said o well and hit it. Seat of the pants felt a little better than usual, most noticable after 15psi of course. So I did a few pulls back to back and pulled over to check the intake manifold, felt noticably cooler than usually (typically its too hot to touch almost). I dropped the pressure switch down to activate at 12-13psi (Im running 21psi). Did another pull, something went wrong.... The nozzle blew out! Took it apart put the washer on the INSIDE of the coupling (silly mistake) and off I went. Did several more pulls on the way back each one feeling pretty good. Leaving the toll plaza I got on and poof went a chargepipe. That hasnt happened in ALONG time.... I'll use this thread to post as i go on about this and i will be getting back on the dyno to do some tuning since i am a little bit richer than i was. I also plan to swap to a larger nozzle, im currently using an m2 which is pretty small. My mix is slowly going to be more and more meth , I may end up running 100% meth or very close to it. When I swap to a larger nozzle i hope it dont bog like i hear happens to some people. From what I read it shouldnt be a problem though since my boost builds really fast. I'll post back later, I gotta go reset this charge pipe in place with a fresh bit of silicone.
