Dry systems are much safer for low horsepower shots. I would worry about the NA 3.8l motor being able to take the stress of the nitrous though, Staying at about a 50 -75 setting should be ok, but no promises. You also may need to upgrade your fuel system, as the sotkc fuel system is marginal at best.

A 50hp shot should be on but I would not go above that with a stock 3.8.

A 50hp shot will wake that puppy up

is a 100 shot safe on a dry system?

100 hp is safe on a dry shot if you have a larger fuel pump. I know 1MTNCAT is running a 125 dry system on his cougar, and he's been doing it a long time. Your results may vary, but a larger fuel pump is a must, and an adjustable fuel pressure regulator is a plus.

yes, but i meant for myself cuz i plan to run a 100 shot also and i wanst sure if i should go with a dry or wet kit. i was leaning toward dry because it just seems a lot safer to me. i have a 4.6 SOHC by the way.

Yeah, Joel's right. He's been using the system for roughly 5 years...on the factory stock longblock at that. Not to mention the benefit that he hits it right off the line.

i think you guys are backwards for our cars you want a wet system a dry system well only flow nos into 1 cylinder a wet system well flow in with the gas!

maybe it was a honest mistake!

Nope, dry all the way, upgrade your fuel system with it, and be done with it. Wet systems have a tendency to grenade the intake, air boxes and whatever else is in the way when the fuel puddles in the bottom of the intake. Just ask Joel on that one. It can be avoided by using a window switch, but that's no fun, everyone wants to use their nitrous for the hole-shot, and a dry system is the only way you can do it on our cars.

Rich,

I have no idea what you're talking about......








That is the result of hitting the spray on a wet system too soon.

Quote:

I have no idea where this thought came from. a dry system flows into the intake, then just as the air that enters the motor, the nitrous spreads out pretty much evenly throughout the intake, and into each cylinder, if you had a 125hp dry shot and it went into 1 cylinder that cylinder would quickly find its way to the bottom of your oil pan.

A wet system mixes the fuel in with the nitrous in the intake, then the atomized spray travels through the intake and into the cylinders. Problem with that is that if the air is not traveling fast enough through the intake the fuel will settle (due to it being a liquid) into the lowest part of the intake, and of course the smallest spark will set it off, and boom, no more intake. to solve this problem the engines RPMs must be higher to give it sufficient air speed inside the motor to prevent the fuel from settling, which is why you cannot spray out of the hole.

Dry systems are great because you don't run the risk of fuel puddling in the intake, but the wet system is a bit safer once you are going down the track, as you are not relying on the fuel rail, and injectors, and fuel pressure, and pump (although the pump must still be sufficient in a wet system as well) to keep the motor from running lean and burning your plugs, and/pistons, piston rings up.

Wet's great on manifolds designed to flow a fuel/air mix. Ours, of course, aren't. Air by itself will happily make turns that the suspended fuel droplets can't, leading to lean cylinders, pooling, and the Dreaded Nitrous Chuff. For just about any EFI motor, your best bet is either a single nozzle dry, direct port wet, or an injector piggyback system.

what fuel system components should be upgraded when installing a dry with a 75 or 100 shot. i know i need a high volume fuel pump and fuel preasure regulator but do i have to upgrade the injectors and fule rails also?

A 75 shot wouldn't require an upgrade, but if you want to go with a 100 shot, I'd suggest at the least, and better fuel pump and Adjustable Fuel Pressure Regulator. You don't need bigger fuel rails until you make a lot of HP. 24lb injectors would be a safe bet as well, but with the AFPR, you can get away without them safely.

i was just reading about nitrous online and i read somewhere that with a dry kit it would be hard to get the perfect fuel preasure because when spraying u want the preasure up and when not spraying you dont want it to high cuzit will run rich and slow u down. would fuel preasure be something that would be a pain in the ***?

Some kits use a vacuum line to fuel pressure regulator that increases fuel flow when the system is activated and the nitrous, etc is sprayed. Otherwise it runs as normal but yes you can also increase it if you like.

You need to check out the System specifics of the ones you are interested in and find out how there system works and what they recommend and go from there.

thanks for the reply, eveeryone left me hangin. what system do you run? i think i remember reading u use a dry kit. how do you regulate the fuel preassure? thanks.

I use a ZEX dry System, with the before mentioned vacuum line connection that changes vacuum flow to the regulator to increase fuel.

Hope that helps!!

That kit for the 96-98 Mustang 4.6L is supplied with all the necessary hardware, parts and directions for the installation.

Go to WWW.ZEX.COM and check out the sight. It will provide you with most of the information you may need.

Hope this helps.

Here's an idea for the super ghetto nitrous kit. Get yourself a 55 gallon drum and spend a few grand getting it filled. Then park it in your back seat. Put in a pump to keep up the pressure. Hook a garden hose up to it. Keep the normal sprayer you use for watering. Drill a real big hole straight through the dashboard and stick a pipe into your intake. Get goin and start spraying for the infinite nitrous shot. See how long you can go before boom!

What is the difference between a direct to port and an injector piggyback system? I thought that they were the same thing? That a direct to port just meant that your fuel injector had an extra nozzle in it to transport nitrous?

And if you are running a direct to port, does it have to be dry or wet, and if not, which would be a better way to go, and why? Here is what I would get if I went with nitrous.

http://www.holley.com/HiOctn/ProdLin...NS/NOSzle.html

There is a complete kit from Summit that has those type of port injectors for about 1500, if I read everything right.

Thanks!

From what I know, direct port is neither wet or dry. A wet system is sprayed into your air box and the dry is sprayed into throttle body I believe. I know direct port is the safest way to go as it distributes the nitrous the most even. Wet systems are good for destroying air boxes (ask Joel).

i thought wet sprayed a fuel/nitrous mixture into the intake and dry sprayed just nitrous into the intake.
