I know there are a handful of people on this forum that run water / meth injection on their XJ's.

I would love to hear where you plumbed the nozzle in relation to the other components on the vehicle, why you decided to put it there, and what size nozzle ended up working out best for you. It would also be cool to also hear about whatever trial-and-error process you went though dialing it in. I've been doing some reading on this and there seems to be different placements for different reasons so I'm interested in hearing about this from Jeep owners and especially XJ owners.

Thanks everyone.

Pre throttle body and supercharger. Snow performance kit. It would trash my TPS if I ran too big of a nozzle. I could make a pull at full boost up a hill get out and put my hand on the SC comfortably. I have to see what nozzle I had installed.

I believe you had the Stage 1 Snow Performance kit. What did you have the settings at? With Stage 1 you just set the PSI you want it to kick in on and it sprays at 100% correct? I'm trying to decide if I should go with a progressive controller or not. Another guy on here told me drilled and tapped the 7th injector spacer and used the Cooling Mist system with a progressive controller and set it on at 2psi and ramp up 25% per pound boost. 2psi 25%, 3psi 50%, 4psi 75%, and 5psi 100%.

Yes mine would fire at 100% at appx 7-8psi boost. That is when I would see the IAT rising. I used a snow 20001 kit with a #2 nozzle.

Also, post some pictures of your set up.

Thanks for the info.

Also the methanol will clean up the head nicely .

Pretty cool. Was thinking about doing the Banks "Revolver" header or Harland Sharp 1.7:1 roller rockers before the water/meth kit, but I've been doing some reading and it seems like the header only gives nominal increased performance at "normal" RPMs. Maybe the water/meth kit is more bang for the buck (since it's like half the price of both) and I could just wait to replace the header if the stock one ever cracks. I'm still not sure yet.
