As I was saying you should consider nos injection after the supercharger. Other guys are saying the same thing also; perhaps they can chime in here and help us come up with a good solution.

Injecting nos after the charger has two benefits I know of, one is the charger does not have to compress it again and the second is with a wet system the fuel pressure matches the air pressure closely so the fuel/nos balance will better reflect reality.

The center of the air blast exits the Eaton/Mag centered in the “V” exit port near the front, not at the sides of the “V” as most people think. If you place a single nos injector in the center of the exit air stream it should mix well with the charger air and not have distribution issues, as the airflow there is extremely turbulent. This approach is a simple inexpensive solution that may work out for you. Looking at my Lightning it looks like there maybe just enough room to fit the injector behind the alternator and under the “Dot” in the picture.

Charles



What do you guys think ???
I'm thinking MAJOR help spraying at the Intercooler
Of course I'd have to survey the situation and see if it's possible,
talk to Sal to get his opinion, see if I can route the lines there, etc...
but your thoughts ???

THANKS CHARLES

Rob forget all that, did you see the system i put in your other nitrous thread?

Well....since you asked

Any single nozzle system in, on or around a lightning manifold is not a good idea IMHO.....let me qualify that....I mean that for anything over about 100 hp. Anything under a 100 hp and it seems to work fine but as the power goes up so do the problems and the amount of power that it SHOULD make just doesn't seem to be there.

The problem as I see it is the homogenous mixture of fuel and nitrous gets the chit kicked out of it trying to negotiate the stock manifold and make its way into the cylinder. The lightning intake manifold was not ever intended for wet flow.....its a dry manifold. If you try to make it a wet flow manifold you will NEVER get an even distribution of fuel and nitrous (at high flow rates).

If you are going to make it a wet flow manifold using a single nozzle then using the PSP plate you once had would most likely be your best bet....run the juice thru the blower I think your fuel distribution would best that way.
If you put the nozzle under the blower it will really screw up the flow and concentrate nitrous in certain parts of the manifold....were that would be I don't no but you could tell by reading the burned spark plugs

Since you asked

Dale

PS...I have never and probably will never own a nitrous system so what the hell do I know ???

Call SVC Motorsports in Scottsdale, AZ - I believe they will sell you the upper Intercooler lid pre-plumbed with the spray bar set-up that I had on my previous 03 L. That set-up running a conservative 50 shot, I gained 6 Tenths in the 1/4. The spray bar is important to equally distribute it so that certain cylinders are not hogging up all the go fast juice

You may have a better idea. How about posting your solution here so we can all see it?

Thanks,

I agree with Dale. The single nozzle works great before the blower because the charge gets mixed more evenly and then exits the blower and gets distributed the same as the rest of the charge. Putting a single nozzle after the blower, is probably not a good idea.

I ran up to a 175 shot through the NX Shark nozzle and it worked great. But going from the 150 to the 175, I started having distribution issues, and I decided to go direct port. The nozzle was only rated for 150 max anyway. I had a custom direct port spray bar setup plumbed into the lower intake. The setup shot directly into the cylinders. You could definitely feel a power difference, as the truck now hit much harder off the line, which dropped my 60fts down. That's the setup I ran 10.48 on, along with the Works 112.

But a direct port Fogger setup would be even better, as the spray bar setup is very crude and has poor atomization. It's just a lot of $$$$$$$.

Hello Charles, How have you been ? Not to steal Robs thread but the trucks up and runnin again with the magnum screamin!!! I had the seat pressure increased and just waiting on Sal to get some new dyno numbers down. Back to topic, I was thinking of plumbing the holley NOS noszle system into my truck if it will work, Its basically an adapter that goes under the fuel injectors and has 2 ports ,1 fuel 1 nos thus resulting into a direct spray into the cylinders. Cant get more direct than that.lol..If my finances are willing i will have results soon enough. And hopefully we'll have another 10 sec magnum powered truck out there!!!!!!!

Great feedback all, THANKS

Chim you wanna buy me that system, I'll take it, I'll take it
Nothing better than direct port injection

Unless Sal has that ole set up laying around
Sal as I said, I can live with the #'s and we can still have A LOT of fun as is,
but I think I would like to try and convert what we have to a longer nozzle and maybe go back to your plate design in time
How we doing otherwise ?

If I am not mistaken I believe the NOS kit Chimshady1 is touting is a dry nozzle above the blower with an adapter to house the stock fuel injector and an additional nitrous system fuel injector. It looks to solve the fuel distribution problem, but we still have to compress the additional nitrous with the intake air in the charger, causing additional temp rise that a direct port kit wouuld eliminate.
An interesting compromise. We need to see the results on our trucks or at least a cobra. BTW NX offers a similar setup now.

i wonder if we could use a direct port system something like the kit for the mustang that goes under the fuel injectors. i would be a sweet setup if it would work on our manifolds

No it is not a dry shot above the charger but instead fuel and nitrous added below the injector into the cylinder. Meansvt00 posted the pic of the system im speaking about on i believe the 4.6.

There is just something about all that plastic tubing that bugs me....it is a big issue on some other threads at the moment and I have to completely agree....it aint right and I cant believe they sell it that way.
Also....and I don't know if this really matters....I don't like the way the nossle system lifts the injector up away from the injector port...it lifts it up away from the manifold quite aways....like I said, I don't know if it matters, I just don't like the way it looks.

I agree Dale, I'm not a big fan of the NOSSLE setup either, but it is trick. But you are right, many people had problems with the plastic lines cracking when the system first came out. I do not know if they changed it since then, but the customers I had running it switch to braided lines.

Oh, and imagine trying to change your plugs with THAT setup .

yeah i guess it would kinda make plug changes a pain in the A$$

but i just looks like a sweet setup
