Honestly how safe is it to install a zex 100 shot on our mustangs...i jus need a lil more power but dont have the cash for a s/c right now please any info would help!

 

Been runnung Zex 125 shot. Works great, recommend Kenne Bell Boost a pump, colder plugs.

 

I posted a similar thread a month or so ago. I went to a tech night with my local Mustang Club, the subject "Nitrous" After leaving there I was still a little skeptical, posted a thread and got some great feedback. A lot of GT's are running nitrous safely. Mine will be going on a soon as my move is done (relocating back to Canada) The new systems have several safety features to prevent damage, but like anything else if you abuse it, the results will be bad. A 100/125 shot seems to be really safe to run in these motors.

 

Nitrous is safe, but remember $hit happens.A blown fuel pump fuse or hung up solenoid can ruin your day. Im not trying to discourage you, i've run squeeze on all my stangs except for this one. I dont know the ins and outs of the Zex kit, but a trick I have always done is to hit the button with only the fuel armed and make sure the rpm drops to insure i've got fuel. I personally have always run an independent fuel system for the nitrous. I dont like kits that tap into the factory system but that's just me being ****.

powerwise, 125 or less and a consevative tune and you will be fine

 

Just ran mine on the dyno. I made 383 rwhp and 410 in torque. These are dynojet numbers. with mods in my sig.

Im on the 100 shot Zex system. Zex rates there shots to the cranks so a 100shot is like a 75 to the wheels shot.

 

Lets see, where to start? The Zex kit is far from complete. You probably will wantsome additional equipment to go with the basic kit. Consistant results from nitrous requires that you have the right pressure before you spray (1000psi). A bottle heater and a pressure switch are required for this. Zero "0" range spark plugs should also be installed. The stock fuel pump is not really up to the task. A Kenne Bell boost-a-pump can solve this issue, or you couldinstall a higher volume fuel pump. A fuel pressure gauge will allow you to monitor fuel pressure while you spray. With the stock pump the pressure was below the required amount. A N20 pressure gauge will let you know when the system pressure is high enough to spray. I also have a Hurst T-handle shifter with the nitrous button so I can control exactly when I spray. Having the system spray every time you floor the throttle gets old real quick. For my car, spraying in first gear is kinda of a joke. The tires spin like crazy. Also make darn sure that the TCS is off when you spray! Excessive tire spin will shut the fuel pump down, this is not good. If you have stock suspension, do not spray if your car is turning, things can get a little crazy when the power kicks in. As you probably know, Nitrous comes on instantly, there is no smooth transition. You tires will spin when it kicks in, especially in 1st and 2nd gears. If you are in a turn and you spray, you had better be prepared, as your car may slide sideways very hard. I know cause I've had it happen. I almost lost control and went in to a ditch. Shortly there after I lowered my car with Steeda springs, upgraded the rear anti-sway barand added Tokico struts and shocks. Now she handles nitrous in any situation. There are also a lot of other accesories available such as RPM window switches and purge kits. It just depends how much you want to spend.
