Hello to all, I have a little input to add. Nozzles are not the same across the board.. Different mfg build them differently and the way they want it done.
You have your 90 degree nozzles, your 45 or so degree nozzle, you straight nozzle, and your pie cut style nozzles.
Each nozzle has its place in the world. Some at the front others at the rear, Some designs do work better, for example, the fan wet design is not my favor it, but it has worked for the last 30 years, and some companies do not like change.. Now the funny thing is several companies are using the vortec design, and calling it theirs, just a knock off thats all.. Here are several pics I found for different nozzles that are out, the order is in NO WAY shap form or presenation of best to worst...

so whos got the best nozzle?

 

LOL well anyone will say they do..

It just boils down to what you need and expect.. many are very very similar there's not a tremendous amount you can do to change the way a nozzle sprays you're not going to gain 50 more hp from one nozzle to the next.. it's just personal preference really.

 

I personelly like the SX2 nozzle.. kind of bias thou.

Thanks for your input Ricky. That is the kind of info I was looking for. I notice that with the different type of nozzles, some 'pre-atomize' the fuel thru a seperate exit while others use the pressure of the nitrous to atomize and mix the fuel.
I was curious, which spray patterns work better in which locations? Some work better in dual nozzle configs where others work better as a single?

 

Most will give about the same performance, bout the only way us normal guys will really tell the difference is if we are into drag racing so deep we are up for a NHRA world championship. Some are patented, some are not and have been copied. For the guy that said something to the effect of if you were doing n2o in the 70's... well I was there, putting my first kit on in 1977 and have seen all the newest styles to hit every year and claim this or that, and usually made minimal difference to most if any at all. So, pick what you like and feel is a reasonable cost, and of course look for quality. Stay with name brand stuff for sure, and of course support your site vendors.

Ok as far atomizing goes there are several that do it before leaving the nozzle. These will work the best in an efi application single nozzle wet kit. The ones that just slam the nitrous and fuel into and area or a wall space just make a mess of things, and there is even one nozzle that tries to mix the fuel and nitrous about 1/2 inch away from the nozzle. What a joke.
The placement of the nozzle has to be considered. Like the straight designs works best when aiming the nozzle and the intake valve, like on an under the runner type set up, small area and need that straight shot. The 90' degree stuff works well on the outside runner like in a direct port or a single nozzle wet kit. When you are entering 90' or so to the air flow.
There are only a few nozzles I would ever run in one of my cars from the pics shown...
One final point on nozzles, you should always check the flow of your nozzle to make sure there are no defects in the nozzles.. In the past a company sent some one and nitrous was spraying up the fuel hole.. What a mess.
You can see in this intake that different nozzle fit different places.

That is one trick set up Ricky. I agree with what you say. I think every manufacture is going to have some less than stellar nozzles, it just happens in any mass produced product. there is even a formula for excepting a certain failure rate, some using a tight rate and some using a sloppy rate. but like you said check them out, you don't want to be the one that your fuel just dribbles out. I think the the vendors on ls1 and the truck forum use good quality nozzles and the failure rate is very low.
