hello, i have a 2000 gt with 60000 miles and under ext. warranty on everything. i am about to get a dry nitrous kit and was to have a 100 shot with it. i know nothing about nitrous.strictly performance said a 125 shot is probably the highest i can go. if i run 93 and colder plugs do i need to get a tune. strictly wants 550 for a chip and tune. that is a lot so i was wondering if i could just get by with doing what i mentioned without blowing the motor up. if not will a handheld tuner work for me. do 4.6 motors have adjustable fuel regulators available. anybody with experience on thise please let me know. all i have done is straight through mufflers and intake tube upgrade before the MAF.
 
First you better kiss that warrenty good by if you add nitrous. LOL

Now I dont know a whole lot about nitrous, but I keep thinking that a 50 or 75 shot is the biggest you want to go on a dry shot. Im not 100% sure though. I know you can spray 100 safely with a wet shot and I know some people say you can get away with 125 but thats pushing it IMO.

A tune is not required BUT if you want to be safe a tune is your best bet. I would also look into a WOT switch, and a window switch if it doesn't already come with it. A hand held tuner is $300 and then your talking $400 for a tune atleast thats how much it costs here so 550 seems like a pretty good deal.
 
I wouldn't outright say a dry shot is "bad" :shrug: Any kit can be set up to be safe aslong as the user doesn't get crazy with it.

Which dry kit are you looking at dastang? The Strictly crew really know what they are doing when it comes to mustangs, though I felt lousy when I brought my little GT there the one time that I went. I was the only 96-98 and there was only 1 other GT :rlaugh: Lots of nice Cobras though ;)

As for the kit--Throw in the 75 jet and see where that puts you. I assume that tune they are offering is with 3 dynopulls with a/f printouts which isn't a bad idea. You could even purchase the chip elsewhere and then just get them to tune it.

My xcal2 is currently shipped off getting custom tunes done (can be done by email also) and 1 of those tunes is for the nitrous on my measely little 98.
 
I'm running a 125 HP shot on my stock tune and my AFR is fat (safe). A tune could get me some additional power, but I can't justify the additional cost right now, plus I want it safe more than anything.
I'd highly recommend a wideband like the Innovate Motorsports LC-1 or LM-1 and do some datalogging, both on the juice and off the juice. Of course, you'll want colder plugs and close the gaps down tighter as recommended.
I contemplated the same issue as you, wondering if I really needed a tune. In speaking with NOS (Holley), they said their kit is designed for a stock motor, stock tune. If you install properly, take their recommendations seriously, you'll be fine.
Besides the wideband and AFR gauge, I have a FP gauge, a FPSS, a window switch and a electronic WOT switch (no microswitch here - it plugs into the TPS). So I feel pretty safe and the datalogging has been consistant...and it freakin pulls like a proverbial freight train...woohoo!
The window is set for 3K-6K and the FPSS is set at 35PSI. So, I open the bottle, purge it, flip the arming switch and when I hit 3K, and the throttle is wide open and FP is above 35 PSI, we go...! I've had absolutely zero problems.
Let me know if you have any questions dastang2 - I'll be glad to help. I'm fairly new to the juice game, but I've done tons of reading and research and I really don't worry about blowing up like some of the horror stories you read about.

it is an edelbrock kit, it has a 150 jet in it now, need to get smaller ones. it comes with a throttle switch too. i saw a conversion kit to make a NOS dry kit a wet kit. will that work on an edelbrock. how much is a windo switch. and what plugs should i get for this.
 
I built my own tune for my car. I pulled 2 degrees of timing out just by doing some data logging with the handheld tuner. i also added just a tad of fuel to both rpm ranges just to be safe. I am running NGK plugs that are 2 steps colder. I have sprayed my 150 shot a few times now and holy god it kicks hard. I mainly run on the 100 shot i was just curious when i ran that so i pulled some more timing for that. but stay with a 100 shot and u will be fine. Also another good thing to buy is a bottle heater.

For the bottle heater i recommend one by dynotunenitrous. I am running this heater and it monitors bottle pressure and u set what pressure u want it to hold at. Mine is set at 1100psi and holds it very very well. Even doing hotlapping at the track on nitrous my trap speed was staying very consistent. so the heater was doing its job holding to at 1100. even with just a few lbs in the bottle it will get it up to the 1100 psi that i want.

NX says that timing does not even need to be pulled out on anything under a 100 shot for their wet kits. I ran with the stock plugs in on the 100 shot for a few months and it was fine. I put the 2 step colder plugs in cause i was curious what the 150 was like. but i stopped using that 150 until i upgrade my fuel pump.

I would say a window switch and a WOT is not really necessary.

also i wouldnt worry about a purge system yet either for it thats more of for looks than anything.

Jets aren't very expensive at all and there are a few places in Houston that keep them in stock if you don't want to wait for shipping and waiting.

I have some NGK TR6s that I picked up from Oreillys for around $1.50 a plug which isn't bad at all. I went with the digital MSD window switch but that isn't necessary since the one with pills will work just as fine. You can find them on ebay and other car sites for cheap. I picked up my digital ws for $60.

The only jets that I have currently is a 50 and a 75 :rlaugh: I'll eventually get around to buying more, but I've yet to even spray since I am waiting for my programmer to be sent back to me with the tunes on it:nice:

Dry shots aren't bad, but there are other kits available that are more safe. Obviously a direct port kit would be the safest. Wet kits are decently priced and don't rely on the PCM to correct parameters for the extra power. I'd rather spray fuel at the same time versus relying on the injectors and fuel pump. Just my opinion. Also, people blowing up there intake manifolds are idiots spraying 150 shots and expecting no fuel puddling.
