I have done the mechanical part of this mount, but haven't run the car yet, so can;t speak to it's effectiveness. I will do so within a day or two, and get back to you. It may seem like extra work, but I thought it was worth while, and worth sharing.

Throughout this project, which is a very custom one, I have tried to make reliability,and practical servicability a high priority. For instance, this Dart has a Ford Mustang T-5 intalled, which involved cutting out the stock crossmember and fabricating a new one to make the change of clutches easier. I have done this once already, and was glad I went to the extra work.

The idea of taking out the intercooler to TB tube in order to change nozzle size did not appeal to me, and I wanted to be able to change the nozzle more easily. Plus, the warning that the nozzle could get sucked into the engine scared me.

So, my solution was to weld a bung to the intake, tap it for 1/4" NPT. Then turn the nozzle hex head off in a lathe, and thread it with a 1/4" NPT die. The nozzle then gets threaded into the bung from the outside of the pipe, just like the temp sensor. In order to remove the nozzle without messing up the threads, I turned a 1/4" NPT union onto the back side of the nozzle, and sealed this with green locktight so the uniion would stay with the nozzle when removing the nozzle from the tube. In order to be able to disassemble the nozzle for cleaning, I sawed a slot in the top of the rear thumb screw assembly so I could get the nozzle apart with it still inside the 1/4"NPT union on the back side. This all has worked great mechanically, and I can see no reason why it won't function fine. So each nozzle now has threads on the front side, and a union permenantly on the back side.

I then threaded a short 1/4" NPT nipple into the union which is now sticking out the back side of the nozzle in the intake tube, and turned the elbow (that was intended to be threaded directly to the nozzle) onto the nipple. The nipple is sealed to the elbow with locktight so that I can easily seperate the entire elbow/nipple assembly from the nozzle when I want to change or clean it. I know this sounds complicated. But there are only two maching operations that take about five minutes, and two additional fittings that cost about a buck apiece, if that. And now I can change the nozzle with ease, and I do not have to worry about the nozzle coming loose and getting sucked into the engine. I did not do the machining, although I could have. I had a professional do it. With this arrangement, the nozzle cannot get sucked into the intake.

This is not to be critical of the stock design. This kind of thinking is just what makes the hobby fun. That is why we are putting water injection on in the first place, is it not?
