Running a 125 shot?

How many people are running a 125 shot on a stock engine? I'm debating this, and ordering my chip within the next couple days, so I kinda need to make up my mind. I know I need to upgrade my fuel pump, the 255 Walbro is on the way. I'm using the ZEX 4.6 kit 75-125 horsepower, if that makes a difference. I'm planning on getting the 2 position chip, with the 2nd position being a nitrous tune. Will I be relatively safe with this? I know safe is a relative word when using nitrous anyways. My car is in good running shape, and has no mechanical problems. I will only run the 125 shot at the track, and I go probably once a month.

Should I go for the 125, or stick with a lower setting? I know the bottom end in these cars are weak, but have heard 125 is OK with the proper tune.

Any feedback is appreciated, positive or negative.

I would not spray more than 75 on a stock motor.

If you want to try 125, make sure you have enough money in the piggybank to pull that motor out and put something better in.

I ran a 75 shot and it wasn't that much. There are a lot of people on here that runs 125 shots and are just fine. I say as long as your tuned for it, then go for it.

I run a 125 shot, and other than spraying too soon and blowing the intake to bits I havent had any issues.....Mind you my motor also has 150k + on it, and it is still holding together......I know 1MTNCAT also sprays a 125 shot, and has done so for years.

I know that my motor will not last forever, especially at this mileage, but when it goes, or come December this year (whichever comes first) I will be putting something a little special in.

Rich.....I have been running a 125 NOS shot (dry mind you) for about 6 months now....no probs whatsoever.....all the local stang guys run 150 shots on their sohc so I think we are "safe" The weakest part of the whole thing will be your drivetrain...you should look into upgrading tranny, rearend, and suspension mounts.

Well any FPR will do as long as it is adjustable up to approxiamtely 60 psi. As far as motor mounts go you dont have to do them unless your are bad or old. Make sure that your fuel pump can withstand the added pressure. The one I have is an inline pump rated up to 80 psi

I have the zex kit and I want to run the 100 shot.
With a adjustable regulator what pressure should it be set at?
Also what fuel pums will fit our cars?
The same as the 4.6 mustangs?
Also how many of you guys are running bottle warmers?

You really need a bottle warmer to stay at the right pressure. It will help in not blowing anythign up, as well as get the most out of your nitrous. Along w/ the heater you should get a pressure gauge so you know what your pressure it at.
As for the fuel pump is should be the same as a Stang. You can get a Walbro for around $130 or less.
You can get a good heater for $149.99 at http://www.speedshop.org/store/scrip...?idproduct=17,
and a pressure gauge for $41 at http://www.nitrodaves.com/outlet/pro...up=1&section=3
or if you have the adapter(manifold) there is one for $25.99

A bottle heater warms the bottle to help pressurize it. This is particularly useful in colder temperatures. The Bottle pressure on most systems are recommended to be between 900-1100 PSI.

If the pressure is too low the system will not work as efficiently/effectively as it should. In the summer time the opposite is true. You need to monitor the pressures to insure it is down to that recommended safe level.

Bottom line is heat builds pressure. All systems have an optimum operating pressure range. Read the manufacturers instructions for their specific recomendations.

the pump is the same as a stang but the strainer (small nylon mesh pickup) is way different, and the stock one for tbirds will not fit a 255lph pump.

What kind of strainer will fit the 255lph pump?
Also what presure should the regulator be set at?
Im glad you said that b/c i was about to enter my cc# in for a fuel pump kit
with strainer and all. I looked it up for a 96 stang.
Will the strainer that comes with the pump work in my tank?

Should just be able to go to Autozone and pick up the strainer sock for a stock t-bird pump. the sock will fit on the mustang pump.

earlier in this thread a guy said it will not.

yes, the attachment where the sock fits on the pump is the same between the two. The design of the fuel pump sock is what differs. It is because of the different design of the t-bird and Mustang fuel tank.

here's a link to MN12's how to on their kit.... it shows the picture of what a t-bird fuel sock looks like. You can look around and find pictures out there of a mustang fuel sock.
