sooo with out n2o i put down 251 whp and 236 ftlbs to the wheels.. with a 100 shot no timeing pulled i put down 336whp and 415 ftlbs....a/f about 12.5...i was wondering why these numbers seem low?? i have nismo intake, aam plenum spacer, test pipes, stillen true dual exhaust, and 1 cold range colder copper plugs...i have a 2003 track with about 59XXX miles...anyone have any ideas or do these numbers sound normal??? i raced my friends 2000 lightning with a built motor and lower pully putn down 410whp and i beat him by about a car and i raced a SS gaymaro on the high way and beat him by half a car..oh yea and the bottle pressure was around 1000psi...thanks in advanced

 

i think thats about right u make more torque the hp wit spray!! good numbers!!!!man i like to dyno mine

 

Don't post anything related to street racing, as it is a violation of our TOU.

Just because you put in 100 shot jets, it doesn't mean you'll gain that exact 100 whp. As long as you used the correct jet sizes, you should see gains around the advertised numbers.

What are your jet sizes, anyway? What does your N/A and nitrous AFR look like? What about the rest of the graph?

 

im runing a 33fuel and a 47 n2o jet...all a/f number were about the same around 12.5...we messed with the jets to get a better a/f ratio and a lil more power...my hp on n2o was pretty steady but ofcourse the torque was huge at first then tapered down to around to around 300...

 

And this is without a tune, yes? That's a big fuel shot.

 

yea i know its the safest setup that we found with the a/f and best numbers...would a dynotune or msd window switch work with my zex box???

 

SEARCH!!! J/K LOL i did for you haha.
https://my350z.com/forum/nitrous-oxi...witch-zex.html that shows how to wire the dynotune switch with the zex box. zex also rates their jets at the flywheel to be on the safe side. nx rates theirs at the wheels, that's why your numbers seem low. nx calls for a 52 nitrous and 33fuel... atleast thats what the tech line says. audiblemayhem says 28-30f and he knows his stuff. right now yours is about the equivelent to an nx 75 shot i believe.

 

hmmmm sooo theoretically (probably misspelled) i could just swap out my jet for those andd it would be ok?? i guess its true what they say...once you spary u cant stay away

 

well i would put it on the dyno again to make sure your a/f is good. right now i have a 52n and a 31f in and i haven't had any problems. i've only had it like this for about a week tho so i don't know how much its worth lol. and yes... it is very addicting and fun haha. i've been through a bottle and a half in a little over a week lol.

 

pshhhh in the first 5 dayz i went through 4 bottles.....im sure my motor hates me with a passion

 

blackz7887, do you have a tune?

If not, I'd swap those jets out with something smaller. What you have there is equivalent to that of a 125 shot. Unless you had your engine built or have a nitrous map, it would behoove you to slower it to something that resembles a 100 shot, regardless of what your AFR may look like.

 

if i ran a 52n and kept my 33f would it be a lil on the rich side??? sooo it would be a lil safe??

 

You could. If you do, then you do. If you don't then you don't. Do a search if you want to find out if you should or not. I'm not going to continuously spoonfeed you all the answers.

 

isnt the reason for this whole website to get answers?? you seem the be the most knowledgable with this, thus the questions

 

Exactly. Go SEARCH FIRST for your answer THEN ask. Stop asking questions which have been asked multiple times and answered multiple times. Seriously. When you read a book or watch a movie, do you just skip to the ending or the good parts because after all, you want the finale and the climax right?

And hell no, I'm not the most knowledgeable regarding nitrous. But I am more active than the others who have more knowledge and insight.

 

depends on the movie and/or the book...usually read the back first...im lookn for quick answers....but as you wish ill search more

 

i have a 36 fuel and a 42 nitrous and i put down 332 wheel horsepower on a dyno jet i have not recieved the chart yet to see my A/F and i am uncertain about torque till i see the graph, i think i should go less fuel with this set up supposidly its only like a 60 shot according to my friend

 

no tune, just going off of what i've read on here. so far from what i've seen nx rates their's at the wheels while all the others rate their's at the flywheel. all these posts say 52 is what its supposed to be...

now again this is for the nx kit which i have... i was simply stating that the reason he wasn't seeing a 100 whp gain with his zex kit while others with nitrous have with a 100 shot is because all the other brands are more conservative than nx. since nx is preffered here those kits are the ones that show the higher gains. i've done quite a bit of research and i know im walking on a thin line as far as a tune goes but i think it should be ok. im only going to use it at the track a couple times a month so i figure with some 100 octane fuel i'll be good to go. now if i were to be using it constantly i would definately want a utec with a nitrous tune. thats actually next on my list(pretty much the only thing i dont have), just not in the budget at the moment. thanks for lookin out 3hree5ive0ero and if you have proof that my sizes are wrong i would definately like to know, but as far as i know those are the sizes for NX.

 

We should make a sticky with the shot that is being run with the mods on the car and how much its putting down. Also list the jets being run.

 

blackz7887, I appreciate you going back (and searching) and responding with references. From what I've read, only ZEX rates theirs at the flywheel, while others like Dynotune, NS, etc are the same as NX. Recently, however, I've been told by a few ZEX owners that theirs isn't at the flywheel, but at the wheels. Who really knows what the jet sizes are for each kit and why (if at all) they vary, I don't know. I guess you might be all right, but at any rate, it's definitely something that I would want to spray constantly (but you already knew that).
