When 50hp isn't 50hp... - Honda Prelude Forum

alphajesse · 07-22-2003, 02:13 AM

I've got something I'd like to discuss... It's been bugging me for awhile.
NX seems to rate it's shots 'low' vs NOS.
It's my understanding, that to reach the higher hp # that their jets produce, that they are simply making the hole in the jet bigger...
So a 50hp NX jet has a larger diameter hole than a 50 hp NOS jet... If I took a NX and NOS jet with the same diameter hole (and everything else equal) and used each brand's respective fogger/nozzle very similar hp numbers should be produced, right?

Unless someone has something to say as to the inaccuracy of anything I've posted above (and if I did, please let me know.)
Do any of you feel the NX rating is dishonest? I realize the same size jet can and will produce different results on different engines, based on CR, size, etc. But, say in a reveiw, a 50 hp NX kit would produce more WHP than a 50 hp NOS kit on the same car... Not because the NX kit has some better design in components or something, but because they are just spraying more N2O into the engine...
So someone buys the 50 hp NX kit, because it makes more power... He takes all the precautions mentioned for his car when using that level of shot. But he is spraying 75 hp worth of N2O into his engine (based on the rating system used to set reccomendations) and blows something up.
I realize that is kind of extreme, but it's something that I could see happening to someone inexperienced with this stuff...

Sorry about the rambling... what do you guys think?

NX rates their shots to the wheels, thats why their jets are bigger, their fuel jets are also a lot bigger to keep it rather safe, they actually tell you to put rather large (compared to what you could actually run on..and probably better) fuel jets in to keep kids from blowin motors left and right, all in the name of safety...as safe as you can get with nitrous anyway

It's simply a different way of rating the systems. NX rates at the wheels, NOS rates at the crank.

yep, you fill both an NX kit and a NOS kit at the same place, with the same nitrous. It is just the NX kit's shot sizes are a little under rated compared to other companies. A 50 shot of NX is probably around a 65 shot of other brands.

What you are saying is definitly true...
cant we just switch pills to the other brand? Dont they all fit the same?

Basically a NOS/ZEX car running 75 shot is running "safer' I would think then a 75 of nx

Dry at least that is true. I don't doubt that on their wet kits, they also include larger fuel jets.
I think a much better rating system would be lbs of n2o/second @ 1000psi or something like that.
Dunno, got ticked off by a ricer the other day who kept calling his NX setup a 50 shot when he was dumping a lot more nitrous than what every other company uses in a 50 shot. He was trying to tell me that NX nitrous was better, cause it made more power, and I kept trying to explain that NOS would call the jetting he was using a 65 shot or so.

It's like saying the h22 can rev to 8000 beacuse a 5th gen hits the fuel cutout at that # on the tach, when really the engine is only turning 7600...

It kind of sucks that I got NOS because I was expecting 70 to the wheels with that pill and I only got 42.

I mean it doesn't suck it's just I was dissapointed. I mean that's the biggest jet that the kit came with.

Ok....first NX jets wont fit NOS without modification...the NOS are bigger (in OD).....Second, its also a factor of NX solenoids and fogger flowwing better/faster....and I know it will be debated, but Ive heard that from many guys with experience in both systems.....

We need someone to post the NOS wet kit numbers, or at least the dry jet size so we can compare it to NX......I got the NX chart, someone out there using NOS spill the beans on your jet sizes...i dont think their numbers are different, prove me wrong

hehe... I'm using a NOS fogger nozzle with NX jets (I found the NOS one locally after damaging the NX one). I had to drill out the fittings on the NOS nozzle a little bit so the NX jets would fit, but I haven't had any problems. I used calipers to get an accurate measurement and a drill press to do this though, so I have a nice tight fit. I would like to get my car on the dyno though, I would be curious to what it is putting out on the ground.
