nozzle shootout

[mrr23]

after some more debating about companies and their 'claims' of how their nozzle is more superior to the competitors, i offered up my 00 formula to put them to the test. in this test, i compared 9 nozzles. Cold Fusion Predator, Dynotune, NOS Black, NOS Silver, NX Shark, NX SHO, NX Vortech, Ny-trex, and TNT. two parameters were tested. first was the baseline jetting of .063" n2o and .033" fuel. second parameter was to match the a/f ratio at 12.0:1. 24 miles on the dyno, 21 runs, 12 lbs of nitrous used. what was found out is each nozzle affected the a/f ratio differently at the same jetting. the top three spread wasn't much apart.


here's the results: http://www.tredalign.com/nozzleshootout.html

Thanks for doing this write-up, must have taken you forever! I bet it was fun though....

Looks like my NX shark nozzle did alright :D

[mrr23]

thanks. i was there about 9 hours. didn't stop for lunch. then it took me about 3 nights at home making all 76 graphs.

[smokinghost]

WOW thats the best comparison of Nitrous I've ever seen....Bet that was a blast...Props to the Pontiac for all the torture..

[mrr23]

and it's still ticking right along.

[05amg]

great write up. keep up the good work!

[MusiccityGT]

Awesome job and some vauable info!! Thanks for your efforts!:worthy:

[NXNitrousMustang]

Awesome work, mang! Thanks for sharing! :)

[mrr23]

it was a long day. after i did all my stuff, i dyno'ed another car that came in.

[Dragls]

What are your thoughts on the edelbrock E1 nozzle? Looking to replace a NOS nozzle.

Is there one you recommend?

This is for a turbo setup.

[mrr23]

never seen one.

[SloSVO]

any idea on how the zex one stands? is it maybe a different named version of the ones already tested.... and thanks for the testing..awesome..

[blue_TcMan]

ok im a bit nitrous stupid, and im sure this is in plain site on the page, but which one do you think worked the best?

:stupid: i was wondering the same thing.

[mrr23]

the NX SHO, Dynotune and the TNT are my picks. look for the red and blue numbers.

[mrr23]

from the looks of it, i would place it around #4 or #5 on the list

[blue_TcMan]

awesome thanks man

[Trick]

Now thats dedication. You Rock! Thanks for all your hard work. :notworthy:

[Trick]

Are you basing the best performance on the HP/TQ #'s. Just wondering if there was a way to critique nozzles by atomization? I would think thats what would make a nozzle good right? I saw you had pressure measurements etc.. but I didn't fully understand all that.

[ShadowStrike]

Great info.
I realize this thread was done some time ago, but do you have any desire to test other nozzles, such as the new Zex one or the WON Crossfire, with supposedly the best atomization and distribution?

i just highlighted the top hp/tq performaners. honestly, the tnt and the dynotune nozzle really impressed me. they hit suddenly and hard when activated. the rest were pretty smooth on the hit.

not anytime soon.

[BTHRB4U]

Very nice work! and very thought out, you definatly deserve some props for that.

I'm amazed at the difference between the sho and nos black, the sho was on top by 50hp/50lbs at 4750rpm and only used a .25oz more.

I think it has has the best power per lbs used as well.

Like you said the difference between the TnT and the SHO is very minimal, your not gonna feel 3hp and its prob not gonna improve your time by anything. And it didnt really use anymore nitrous then the SHO either. Both seem to be pretty good at what they do. Thanks for opening some eyes, great work!

Hi,

Newbie to this site. Thanks for this info, it is very informative. I'm a little new to nitrous and have a basic question. Are the jets interchangeable between all of the nozzles that you tested? I am currently using a NOS Fogger 2 nozzle and have been thinking of switching to a NX brand nozzle. I was told that my NOS jets would not work with the NX nozzle, so I have been hesitant to switch because of the costs.

So I was wondering if you had to use different manufacturer's jets as well.

Thanks,

--jack

[srsnow]

The jets will not interchange. However you can get an NX nozzel then get 2 NOW style jet fittings and switch them out. This will allow you to use the NOS jets. Just becarefull taking the NX fittings out they are put in with red lock tight so you may need to heat the nozzle up a little.

[jackpg75]

Interesting. Since I'm new, what's a NOW style jet fitting? Maybe that's a type-o and you meant NOS-stlye? I think I understand what you're saying though. Where can I get the fittings? Oh and would it affect the flow characteristics of the nozzle?

Thanks,

--jack

[mrr23]

i think he meant NOS. actually take the fittings out of the NOS nozzles and put them into the NX nozzles.

[srsnow]

Indeed I meant NOS I just have fat fingers apparentley.

[BakaN20]

I remember reading that article when I first started researching about nitrous. Thanks!

[mrr23]

you're welcome

[Heretic]

Are the NX Shark and Piranha the same nozzle other then the body height? And does that height affect the performance of the nozzle??

[mrr23]

the pirahnna nozzles are used in direct port applications. with this in mind, it's most likely a 1/16" NPT nozzle versus a 1/8" NPT nozzle like the shark and SHO. so, the orifice size of the holes drilled into the nozzle will most likely be smaller.

also, the jet adapter ends could be different orifice size as well. here's a pic of the shark and SHO nozzles. you'll see how much different the openings are. shark = .093 SHO = .116

Looks great !!

Good job on this.

There is just one question:
How much HP did the nozzle's say they would provide? Is that setting a 125hp shot and did you actually get more/less ?

[mrr23]

setting was for a 150 hp shot. you can compare the NA runs to the nitrous runs to see if they went under/over. none went over.

[Heretic]

Yeah the Piranha is a 1/16 NPT nozzle. But it's also the nozzle NX includes with the Sport Compact EFI Wet Kit. Probably just because it's easier to pack into a tight space, but honestly they should of just included the shark nozzle. It projects deeper in and get more into the middle of the airflow.. :(

So I guess the spray patterns would be quite different, but it seems most NX stuff is pretty decent anyways. (other then the old chrome bottle valve siphon tube thing)

[Robert56]

I also remember the when this first came out. A great job and dedication to the facts. what i came away with, is this, no matter what nozzle you use, if we truly jet it for and verify and 100rwhp shot, we are going to have a 100rwhp shot. One company rates the 100hp shot at 100hp, but really they send 125rwhp jetting and everyone thinks their kit hits harder, lol. Great marketing ploy.

As someone stated, it come down to atomization and flow being what to look at for a great nozzle. I do propose that some new nozzle technology has come forth. This company claims higher HP per same amount of N2O. I am not going to go into it here, but this time they have all the dyno sheets and testing to back it up. The Company, this time, is not Cold Fusion, whom made claims that were never backed up. However, the Predator nozzle may have proved superior in a wet DP set-up where it's technology applies more readily.

When talking about these nozzle is small HP street/strip applications, some of the nozzles will not show that they are superior. Most of the wet nozzles are singles snatched from the wet DP kits. We need to do a comparison based on dedicated single nozzles that were designed to work in the neck area of the intake tract. Also, now that we have NANO technology, we can make certain that no variations in bottle pressure have any impact on results. Now I am not trying start any crap, just throwing some thoughts out and any critiquing will be welcomed. When I have time and permission, I will certainly lay out this new nozzle to consider.

what else do you have for mods besides the bottle? number looks good, really good torque
