ok i just installed a used zex dry kit on a d16z6. i cant feel it i took the intake off and hit the throttle and its spraying but not a huge 55 hp difference. could the bottle be getting empty? the guy i bought it from said it was half full when he gave it to me but i purged the lines to get any crap out and sprayed it a few times to see if everything is working. also on the smaller line going to the intake one of the swivel fittings on the end cracked cause i over tightened it. what size hose is that? on the zex site there is -3AN, -3AN .086 ID, and -3AN .106 ID and then -4AN but i think thats the larger one right? thanks

 

don't think your going to feel it, its a small shot.

i sprayed a 60 shot in my gsr motor and i didn't really feel that either.

its not going to be like F&F style...

pay attention to your mph and see how much faster it rises up.

 

i know but shouldnt i atleast feel 55 horse power? and where can i get the bottle refilled at?

 

Yeah you wont feel it, but you should notice a stronger volume in overall pull.
Im running a 35shot with 10psi on my Y8 and I dont feel any major power at all but I do feel 3rd gear pulling stronger to redline. Thats all I was after.

 

when u have half a bottle u pretty much dont have anything. the first 5 shots seem to be the only ones that matter, with a bottle heater there is a maybe a couple more. the bottle pressure is lower so the shots arent as potent. i sprayed a 75 on my gsr hatch and my god did it rip until about 5 shots then it felt like a quick all motor setup. and that crack may leak nitrous out so keep the bottle on and listen closely to that crack and thats how u can tell.

 

55 shot does not equal 55hp

 

If you can't feel a 55 horsepower jump you have way to many ponies to be streetable as it is.

You might not be feeling the power for a few reasons. Most dangerously is that you could be going lean. Less dangerously is that the ECU might be yanking timing. Least dangerously is that the bottle is empty or not filled with nitrous.

 

ok where can i get the bottle refilled at? some one told me a welding shop? the closest speed shop is 20 mins away should they be able to fill it?

 

i got mine filled at a machine shop.

just cause you have a 55 shot pill, doesn't mean you gain 55hp.

zex is like the safest kit, so a 55 shot is like 30 more hp.. not 55

remember, your not going to get that big rush like F&F , so don't expect to feel that. just run somebody you have ran before that beat you, then see if you see the difference.

my friend would beat me. then i put the zex kit on and tried it out. i didn't think it made a difference. then i ran my friend from a roll, put like 3 cars on him. then i knew the zex was working just fine

 

a bottle heater will help!

or cold and almost empty. (bottle pressure is so important with nitrous!)

a ZEX 55 shot was nuts on my bolt-on's zc setup - felt like a stock h22 ..... you definitely should feel it.

 

yea i know im not gonna get an insane suck me back in my seat feel. but watching the rpms with the bottle and without almost seems the same. im gonna find a place to refill the bottle and throw the 65 shot in and race my buddie like you said. thanks for the help.

 

ok i just talked to my friend who told me where i can fill it at but he told me to put the bottle in the freezer and keep it cold when i take it to get filled? i know he know more about nitrous than me but is this right?

 

definitely keep it cold before you get it filled

 

A good shop will freeze the bottle before they fill it.

I had a 50 shot and a 75 shot on my b16.

The 50 shot you could feel and the 75 shot you could REALLY feel.

Stock motor with 50 shot, i put down 182WHP-141TQ on a b16 with just intake. YEs it was a ZEX kit.

 

hhhmmm maybe its just me but my 55 shot hit hard on my mild built up ls/vtec all motor i could slam the throttle down 2nd gear and not break them loose but the 55 shot just smoaked them off in 2nd on street tires of course. a 55 shot will give u 38-40 hp at the wheels my buddy had a 55 shot on his accord and u couldnt feel it either but it was faster he was only like 4 cars behind me instead of like 8 cars hahaha

 

Someone had posted earlier in the thread that the ZEX kit is the "safest." That is correct, their 50 show was dynoed at a 35 hp increase. SO just keep that in mind. Also remember that you want to have the bottle positioned correctly, not only where it's mounted in the car (parrellel with axles, valve towards front of car in the trunk), but that the bottle is sat the correct way in the mounts. NOS bottles are usually at about a 45 degree angle when mounted parellel to the axles. Usually straight forward when mounted with the valve towards the front of the car. And lastly bottle PSI. Which is directly related to temperature of the nitrous. Optimal bottle PSI is 900-950 PSI. If you use it outside of that window, that will also directly reflect performance. That works out to be about 80-90 degrees Fern. of ambient temperature.

I don't see how one nitrous kit can be "safer" than another, tuning being the same.

They are all the same. . . the only way you could prove this to me is to document the frequency at which the solenoids that come with the kits fail OR you could call one of the kits on the way that the n2o/fuel mixes. . if you thought it wasn't atomizing properly, etc.

There is nothing "safer" about over-rating your products.

That's like saying, well a Jensen amp will put out 50W when they claim 75W. . . so running the Jensen amp is "safer" on your sub.

Amp = Nitrous Kit
Sub = Motor

So please tell me how the Zex kit is "safer" than say the Nitrous Express kit when running the same HORSEPOWER shot. (not pill size because they tend to vary from one co. to another)

also. . . . I notice that some of you are saying. . . ahhh xx shot from this kit will give you such and such horsepower gain.

Not every setup is the same. A 50 shot may show a 35 WHP increase on one car and a 65 WHP increase on another. It all depends on your tuning and your setup.

 

Maybe I should have clarified when I mentioned "safe." It is considered to be a more put square peg in square hole install. As opposed to the kits from NOS (Holley) where the install takes a little more then the begining noob may be ready for. The number that I used for that reference came out of an article in Honda Tuning done a while back. They tested the ZEX, and the NOS kits against one another on the same motor, and saw a difference between the numbers that they got, by only changing the nitous kit.

Question: Will the percentage of power increase be the same in a highly modified engine compared to a stock engine when using the same kit and jetting?

Not really. In most cases the percentage of increase is greater from a stock engine because it is not as efficent as a modified engine in a normal "non-nitrous" mode. However, since the effects of nitrous oxide magnify the output of any engine, the total power output will be much higher in the modified engine.

I can see where you're coming from when you say safe in that respect.

 

I bet on low bottle pressure. Either from too low on nitrous or cold bottle.
If you didnt research on where to get nitrous in your area before getting a kit then thats your dumb *** mistake.

Also running rich will kill the effect.
And last but not leaast 55hp jets will make about 30-35whp. IMO not enuff to feel alot. i didnt start feeling the shots enuff to make it worth it until I went up to like 80shot

 

you need to know waht afr you are getting with that 55 shot dry. if you are running lean that will cost you hp and engine damage down the road.

actually you are wrong. Leaner makes more power. But less conservative.
Rich looses HP. but more conservative.

 

when i installed my first nitrous kit i placed the nozzle away from the throttle body on accident causing a major loss in power. haha
