If you have no personal experince with nitrous oxide do not post!!!

For every one else. What experince do you have with the 4.7 and juice. It seems like the motor would respond well to it since it has modest compression and responds to boost well.

Like most modern engines it has a easy point to tap into the fuel rail for use of a wet system. And seems to like additional timing.

Unless you have the HO pistons and rods, you are limited to the amount of spray you can use. The powdered metal rods will not hold up for very long if you go over a certain hp over stock. I don't remember off the top of my head what that was but I figure an additional 50hp is the max these rods will take before they break.
Now, if you already have the HO pistons and rods, then go to town. Being forged you will be alright with a 100hp shot.

For me I have a complete HO swap that we overhauled with new bearings, rings, seals, valve seats, etc with about 15,000 miles on her since the rebuild.

Man the forums have been slow lately.

 

[tommysdodge]

the rods in both motors are the same and that is the weak point the rods cant handle much and problem two is the top ring on the pistons is 1/8 of an inch irc for the top. 75 shoot is safe 100 will be pushing it some people have had no problem running a 100 shot some its went bad for. Also You dont want to advance timing with nitrous either thats a bad combination.

50 shot is about like a superchips programmer, 75 shot you can really feel never went beyond that but I've got some videos of my truck at dragstrip, wound up killing clutch after 15 passes but was fun

N2O

Well I posted this question a couple days ago and never received any response so I'm going to try again. These forums have been really slow the last few weeks. Anyway, I have a 04 dakota 4.7, I have been entertaining the thought of a nx wet system. I've done all the little mods and h/o cams but getting ready to put 08 cams/intake on. I have a custom 4 inch silcone intake tube and have the fuel rail mod done. So my question is can I put the nozzle in the silicone without any bad effects or do I have to go to plastic? And what's the best way of getting fuel to the nx system with have the fuel rail mod done? I did the rail mod with ss braided line. Would I be able to put a T fitting somewhere without messing with the fuel flow? Thanks in advance, any help appreciated.

You could use this on your line from tank:

In the adapter port screw in one of these:

Make sure to safely bleed fuel line to fuel solenoid when done. Also check fuel system to make sure flow is good and pressure is correct. Run a cooler plug and get a tune (recommend Flyin Ryan).
Have fun!

So on the fuel rail mod are you talking about where you Change the crossover with s's line and the rest of the old rail is still there? If you you can just tap the rail where it has the valve for fuel and with the silicone if it's the hard kind I wouldn't see the problem with it

 

[J04dakota]

Turbojoe62- thank you for the links. I was looking at the one fitting you sent and I have to hard lines at the fuel rails that aren't in use and I could probably put a hard line fitting on there to get the fuel pressure. And it's on the rail by the injectors so that'll tell what the pressure is at the rail. Or I could put it the fitting you sent inline under the truck or try to get it on the line before it hits the fuel rails. I havnt one heat range colder plugs in already. And no offense but I went to nick(airram) with questions before with tuning and n2o questions etc. I still havnt heard anything back from him so I went with hemifever and I'm really liking the way he's tuning my dakota so I'll prob just stick with him. Thank you though

Tommysdodge- I totally eliminated the crosover.I took two passenger side rails so I have two Schrader valves, capped the ends of the rails(where I cut the crossover out) and have a efi quick connect on the fuel supply line and have ss line come out about 8 inches so it's near the middle of the intake mani. With a y block(fuel log) whatever you wanna call it. Then 2 ss lines splits off and goes to the schader valve on each rail with 120 degree AN fittings. And everything's wrapped with heat sleeves. The silicon is pretty sturdy, got it from silicone intake systems.com I've seen it used for elbows on intercoolers.

 

[J04dakota]

The silicone I have for me intake tube is 9 ply. 5 layers of silcone and 4 layers reinforcement. 200 psi burst, 50 working psi. I can't remember the degrees it can withstand. But the reason I did the changes to my fuel rail is so the fuel get to each rail simultaneously and the temps of the fuel at each injector is about 10-15 degree cooler. Does anybody know of a plate system (N2O)that will bolt to the 4.7 intake? I can't find anything in my searches.

The only option I know of is AIRRAM's Sullivan conversion you could then use the 4150 plate. Other than that I haven't been able to source anything better than the fogger in the air tube.

 

[J04dakota]

That's a nice intake an all but that's stupid expensive. I could see if someone was running a crap load of nitrous but idk. Oh well it was worth a shot. I guess I'll just go with the nozzle. Thank you for the help and again I'm not trying to offend anybody that supports airram but I try not to buy stuff from him because of my experience.
