Hmmmm....interesting. NX wet kits make 150rwhp with .063/.034 jets....both of your cars seem to be putting out much less horsepower than rated. Or is this another manufactuers jets?

they are nx jets in the ny-trex kits. ny-trex rates at motor not at wheels. does the nx kits still make the same 150 rwhp when you have heads, cam, bolts ons when using same jets? or is it only if it's a stock car? most kits, that i know of, rate theirs using stock motors.

The NX system does not matter stock or non stock, 150 is 150, measured amount of fuel and nitrous = x hp,,,

i went back and looked at the jets i have in her car. they are .062/.033. ny-trex rates that at 150 motor hp. now, doing the wonderful 20% loss ish, that makes it about 120 rwhp. it put 110 rwhp. funny how two companies rate the same basic jet scenario differently. ny-trex looks for a 11:1 ratio on their jetting. which is where mine was.

now, i look at my compucar kit on the 00 formula. again, they rated the .063/.033 at 150 motor hp.

back on 7/17/2004 i was running 200 motor rated compucar. .076/.046 jets.
NA 291.35
200 n2o 426.57

gain of 135.22 only mod was a SLP airlid. cutout closed.

same day, i did it with open cutout as well.
NA cutout 303.42
200 n2o cutout open 442.05

gain of 138.63 rwhp.

so, what makes the NX, TNT, etc.. .that rate at rwhp get more than the NOS, NY-TREX, Compucar, etc... that rate the same jet sizing at motor?

You put the 62 33 combo in an NX system single nozzle, you will yeild 150 hp or darn close.. Not sure why they are not making the power. We do.. Nozzle design I am betting has something to do with it.

so, what size orifice is in your nozzles? the ny-trex is .110 on both fuel and n2o. not sure on the compucar nozzle. it's pretty basic design on it though. i'd be willing to put that to the test. one way to find out. how much for one of your nozzles? i'll front the dyno time to find out.

ny-trex nozzle


what about nozzle location?

NXRICKY

iTrader: (1)

A little more than just a nozzle you would have to do the whole system.. The nozzle is a large part of it, and if you wanted to do a comparison , I will sale you the nozzle at 40.00... Let me know.. And the Shark is .093 both side which only comes into play if you are maxing a nozzle out..

where do i send the money? and is that shipped? also, we'll need to discuss test parameters. that way we are on the same page. reps are at stake here. i want it to be as fair as possible for both companies.

while on the subject of the whole system, the ny-trex solenoids have a .081" orifice there as well. 4an feel line to noids. then 3an out of noids to nozzle. the rest of the 'whole' system would be just the noids, right? lines are lines. well, we could get into hi flow valves on the bottles. if that's what's supplied in standard run of the mill kits.

if the nozzle works out, then we'll discuss noids at that point.

just got off the phone with ricky. this will happen. will use the 99 formula white car. look for this report come january.

Im betting nozzle design on this one as well.... The Nx and TNT nozles flow well

Robert56

iTrader: (2)

Well if you read the post TNT vs NX, you would think that nozzle design really plays no role. You jet it for 150rwhp period, end of story. some companys use a slightly diff ratio of fuel to n2o but from all the arguments, seems if you want 150rwhp from what ever company just jet it that way, and you'll have exactly the same torque.

iTrader: (3)

well, you would think that. apparently, i'm only getting 110 out of 150 rwhp on the .062/.033 jets i use in the wife's car. even on the black 00 formula, when it was set at 150 .062/.033 i only got 128.74.

this is when i first got the car. no mods done at all.
NA run 276.62
150 n2o 405.36

Regardless of the claims, and every company has a variation to numbers, jetting on the dyno is the only way to Know for sure. Your running a 110rwhp shot, and a 129rwhp shot respectively. Now some fine tuning with a/f and the timing may net a little more. However, the vast majority of users state shot size by dyno numbers, cause they tell the truth. Those kits will put out true 150rwhp shots, just jet them that way. Your kit is rating at the crank, and if you take the standard 15% drivetrain lose you get, 127.5rwhp, so close to their rating, at least one car anyway. Jet them bad boys up, no need for new injectors, you are not running out of injector, imo.

Power made is in direct relation to nitrous flow. Since he is making LESS power than rated with NX jets on two cars, the nozzles being used flow less than an NX nozzle. End of story.

Robert56

iTrader: (2)

But do you realize how many guys jet their NX kits per nx and end up with less than 150hp, it happens often. There are so many variables. His nozzles are not maxed out as you imply. Could be resrictions elsewhere, like a combination of hard 90* fittings for an example. I don't think there is a nozzle on the market that gets maxed at 125hp. Bottle presure plays a role, bottle line lenght plays a role, electric bottle noids play a role, redundant noids play a role, and VE of a motor plays a role, filters play a role and so on. This is why, if you want 150rwhp, then jet it to that on a dyno, then no more guessing.

personally, i was never worried about the dyno numbers i was getting. i accepted the percentage loss. until this thread. when you see ,for example, NX rating a .062/.033 as a 150 rwhp shot and ny-trex rate the same jetting as 150 motor, you have to ask why.

after talking with nxricky, i'm even more not worried about fuel needs with my system.

all i really care about is track times.

NX shark nozzle has .093 orifice on both sides
ny-trex nozzle has .110 orifice on both sides

where would the flow restriction be in the ny-trex nozzle? could be in design. we'll see come january. personally, i kinda agree with nxricky. it's the small solenoid that's used in both compucar and ny-trex. then again, the ny-trex has a .081 orifice in it and the pintle valve opens off the seat way higher than a NOS solenoid. ken at ny-trex showed me both.

one way, or another, i'll get some actual data on the kit differences.

I have tested both nozzles back to back. On a 100 shot the ny-trex nozzle made 5hp more than the nx, but on a 200 shot the nx made 10hp more. On the 100 shot both made more hp than advertised and on the 200 both made less hp than advertised.
