It is a wet system that uses 1 shark nozzle in the air intake tube. Adjustable from 75-175. When I got the car dynotuned, at 950 psi the kit delivered to the rear wheels 101 hp and 132 more ft-lbs of torque on the 100 hp setting. Now I run the 125hp setting with a SCT nitrous tune and Autolite HT0 plugs, which are 1 heat range colder. The kit also includes an adaptor to get fuel from off of the fuel rail. Also, the system has an arming switch, but also a wire that runs off of the TPS. Once armed, the system comes on automatically when you floor it. The system has worked flawlessly for me so far, with many passes at the track. You can see all of this in the picture attached....
sincitystang said:Thanks guys, but the single fogger wet is not as efficient as a direct port system. I know this because from experience, each cylinder is not getting an equal amount of NOS, and if you have a manual trans, its always good to use a progressive type controler that you can program so you wont kill your engine in a BOG or miss shift. Dont want any accidents. I use to have a single wet in my LT1 Camaro and one day I had a few cylinders lean out and blew the sparkplug tops of them. I dont know if the 4.6 has this issue of leaning out, but when i switched to the Direct port system, it gave me better response and a lot more power. Do you guys know anyone who has done this system yet? Then again, i"m a new FORD man now, and what the heck do i know?

Mustang Sammy said:I also have the ZEX kit. I have it set for a 75 HP shot, but was wondering if anyone is using more. The ZEX installation instructions, which seem to be pretty much the old instructions for previous years, say that you should change the spark plugs before you go higher than 75. Here is the catch, Ford has a patten on these plugs and no one makes a performance version yet. Sooooo has anyone tried higher boost? If so please let me know how it works for you. I can't stay at 75 long![]()
