ricky, i just got the NX nozzle today. here's pics comparing the two.
this little compare and dyno test is a result of this thread. trying to figure out why ny-trex rates the .062/.033 jetting as 150 motor versus NX rating it at 150 rwhp. ricky made the comment that he bets it has something to do with the nozzle design. so, i took him up on the 'bet'.

green = ny-trex
blue = NX



what i noticed here is the NX nozzle brings the nitrous in further away from where the fuel comes in at. ny-trex brings both in at the same spot. NX nozzle is practically a 90* angle. the ny-trex nozzle spray comes out at a 45* angle.


the NX inlet are .093" openings. the ny-trex are .110" openings.

ricky, i also measured the nitrous -3AN lines where the flared end (i think you called it the 'hat')rests on the nitrous jet. the compucar -3AN and the ny-trex -3AN measured the same. i can say it's bigger than .081" i used an allen wrench that fit into the hoses. and the allen wrench wouldn't fit into it.

So the hose is or is not larger than .081. Little confused there..
Glad to see you got the nozzle..

the hole in the hat it is bigger than .081". the allen wrench i used fit into the hose hat, but not into the .081" jet i had.

what size is the ones in your hoses?

Nice work! If you look at the design of the T-rex nozzle vs the Nx I think its pretty clear that the Nx COULD get better fuel dispersal in relation to the nitrous plume. It appears in the NY-trex design, that the nitrous plume really wouldnt be very large at the point fuel is being introduced. In the Nx design, the N20 plume has had a chance to spread out an develop before fuel hits it.... Just a hunch, will be nice to see actual concrete test results on your car. Great illustrated pics BTW!

PS. I thought a 3AN line is a 3AN line is a 3AN line? No differences....Are you saying you've seen big differences betweem manufacturers braided line IDs?

the line dimension is the same. what ricky mentioned to me was the flared end where the jet will be resting on inside the nut, called a hat. some times that hole is a different size.

Hmmmm. interesting....

The nitrous plume in the NX nozzle actually seporates creating a void for the fuel to get sucked into. Just after that point the plume comes back together. A very small area to get the fuel INTO the nitrous stream.. I am curious to see how the tests go, just comparing the nozzles. There is alot more pieces involved in making a system but that is another thread. good luck

What is the verdict?

mrr23

i'm awaiting nxricky to approve what i wrote up about it. let's just say i found something really interesting.

You shuld be able to post without the sponsors approving it. We need to know if some products perform better than others.

I agree, we the end users should also be able to critque your findings. I am not saying Ricky is not qualified, but share information with us all.

that's not what i'm getting at. it's called professional courtesy. i agreed to let him review my findings before submitting them. i have already shown the information to ken at ny-trex. he's ok with it. don't worry, all will get to see the results.

They seem pretty close in hp/torque numbers, but does show what a/f can do and also the bigger noids. This is the reason we chose the big noids in our Pro Dry kit, to eliminate any flowing restriction. Nice work, mrr23, must have taken awhile to do, and a few $$. I will come back and review in more depth later, thanks for the effort, as we will all benifit.

Good test. Looks like the NX nozzle inched out the Nytrex. I wish you could have used the supplied Nytrex jets with the Nytrex nozzle though.

But IMO...as I Have always said...most of the newer designed nozzles will perform within 2-3% of each other. Its the makeup of the entire kit as a whole that is paramount. Any weak link in that equation and the HP #s will suffer as seens here just by switching to a larger noid your gains were excellent.

This is not to say nozzle selection isnt important....because it is. You dont want a cheap nozzle being your weak link just like you dont want cheap hoses or noids.

Mrr23...now we just need you to do a TNT nozzle and maybe a CF and NOS

Al good idea on testing other nozzles. However, I think mrr23 should see which nozzle maxes out first and note the hp and torque. I would let him use my car, but just to far away, so he gets to use his wifes car.

ny-trex uses NX jets in their kits.

what i found neat is how the NX nozzle leaned the mixture out. ken, from ny-trex thinks because both pull out at the same point is why his has a richer mix. we are talking about a half a point here.

ken also explain his idea of once you hit 80% jet to orifice size of the noid, you have maxed the noid out. .063 jet and a .081 orifice netted me 77%. using the .125 noid netted me 52%. which in turn gained me 18.5 rwhp. this is what surprised me to a point. basically, you will never optimally flow the maximum orifice. what some i talked to suggested was as the nitrous is flowing through the noid, it starts closing up due to freezing. seems to be substantiated in this test.

in this case, bigger is better.

now, i'm still not at 150 rwhp as NX kits rates a .062/.033 jetting. i'm still missing 20 rwhp. only thing left, i see, is the bottle valve. or is 11:1 ratio too rich? i made the most power when i was at 12.5:1. being 3 rwhp isn't much, so nozzles between the two are good.

now, if TNT, CF, and NOS want to supply me with some nozzles, then we'll have at it again.

one things for sure, i need to get another large valve for my car. and get my 200 shot to be 200 rwhp and not 136 rwhp.
