Zex rating WHP or FLYwheel hp.

[02Vortech]

Okay guys i have a zex nitrous kit on my blazer. Its a wet kit 75 to 55 hp. I know that NX is rated hp to the wheels, but i think zex is rated to the flywheel. SO! should i go w/ a 100 shot on zex to make 75 whp....????? First i gotta get a ignition controller to retard the ignition but i was wondering because sooner or later im going 100 shot.

Go to a Dyno and tune it to the HP you want to be safe

[02Vortech]

im getting a dyno tune hopefully by mid novemeber....

Zex jets are rated to the flywheel. I picked up 34hp an a Zex 55 shot. After much research I found that NX makes the best jets EVAR and are a drop in for the Zex lines. I installed 50 shot jets and picked up 6 additional hp over the Zex jets. I also dropped jet sizes by 5hp. I have dyno graphs to back up this research. Zex jets (55 shot) = 173whp / 208 wtq, NX jets (50 shot) = 179whp / 213 wtq. I have since installed NX 75 shot jets but have yet to return to the dyno. Go and pick up yourself some NX jets in .041 (n2o) and .024 (fuel) for 75 shot.

When you go to the dyno make sure you have them do A/F, all nitrous companies kits run around 11-11.5 A/F, you can pick up a few extra ponies by tuning around 12-12.5 A/F and still be fairly safe. This can be done several ways, SAFC or smaller fuel jet are 2 examples.

BTW, nice avatar.

^^ wow that is a really good info on n2o... :thumbup:

thanks, nice avatar.....:rolleyes: Yea the shop im using has a portable dyno so im gonna get them to get me a full dyno tune. when i get the money im ordering a wideband conversion for my crappy autometer guage. But 1st im building the transmission. Corvette servos/shift kit/ royal purple fluid, and a transtemp guage. Do you think that with the dyno tune they can remove my governer? And i think im gonna order a set of NX jets now. They have 35hp jets which i would like to run on a daily basis.

O yeah question are you running a window switch with your set up. I got one from MSD. A digital RPM window switch that i have integrated into the system as well as a purge kit. Just wondering what you got.

[Superalty]

My kit consists of the following: Zex Wet, NX Jets, Dyno Tune purge, bottle heater and blanket, Autometer N2O pressure gauge, and MSD Digital 6+ to retard timimg. Just couldn't justify the $$$ for window switch with a manual trans and wet kit. They will not be able to dyno tune your car much outside of jets and timing. You need some sort of handheld tuner like Diablo Power Tuner to remove governors.

Do you have a trans cooler now? If not, I would recommend one for the auto tranny. Also that 35 shot for daily driving won't last long. You'll buy a 6+ and keep the 75's in all the time. Let me know if I can be of any more help.

Yes you can. I got the dynotune purge kit as well, i was wondering how did you get the line that you run to have the purge exit to stay in place. I dont know how to mount it so it will stay. Thanks:bowdown:

I think im just getting a MSD6A box, w/ some plug wires and ill be fine. On my motor i dont need to retard the timing at a 75shot because my low compression... guys run a 75 shot all day long on my motor with out the retard in timing. I wanna try to make 300whp on a 75 shot but i dunno..... Guys makin 300whp on my motor are making 400 wheel torque as well... thats why im building up the tranny next. Yes im looking into a transmission cooler and an oil cooler just keep everything safe. But first i gotta get the damn thing to work.

[Superalty]

My purge exits in front of my tire, so I drilled holes in the plastic trim and criss crossed zip ties over the line. Hasn't moved in over a year. If you want to purge at the hood or grill I would suggest the cable line screw holds. Its the ones that the line slips into and a screw holds the lines down.

Like this:

The 6A would be perfect if you don't need timing retard. How is your exhaust system setup? You need to get all of that spent exhaust gas out fast.

[02Vortech]

the exhaust is stock. Im saving money for shorty headers, and a 2.75" exhaust w/ it dumping right after the muffler. So i dont have 2 bend the piping all around my rear axle. Plus tips look horrible on my truck. But all together it'll prolly cost me $600 and making $7.25 and hour plus my mom makes me put half in the bank.... money doesnt come along very often.

[sparky]

wait wait wait, you people actually tune for a 50 shot?

btw, you wont exceed 150 crank HP with the zex solinoids, they are CRAP.

and to the idiot who says NX jets are better, the jets are larger since they make WHP #'s. so you just put bigger jets in, not "better" jets. moron.

anything less than a 150 shot is pansy shit.

[Superalty]

Actually the opening in the jets are the same size. NX steps the jets for better flow much like a 3 angle valve job, 30% better flow. If you had done any form of research with the manufacturers you would know this.

You fucking kids come in here running your mouths because you saw both of the F&F movies and think you have a clue. If you spent half the time doing your homework as you do running your mouth you wouldn't like such an ignorant uninformed child when you post.

The numbers on the side of the jets are not just a label. It is a measurement in thousandths of an inch. If you have physically seen Zex and NX jets side by side the cones look very different. But I understand it is much easier to type some crap than actually do any work.

Just so you are informed for next time, Zex 55 shot jet is .032 and NX 50 shot is .031. So NX physically uses a smaller jet for N2O, which yields 3.15 less horsepower and still gained me 6hp over the Zex jet. These were the jets used for the dyno.

So do the world a favor, pull your bottom lip over your head and swallow.

[sparky]

hey dumbass, a jet is a piece of metal with a hole drilled through it. the number on the side is just that. a number.

thats why TNT kits make 50-60 more WHP than NX kits with the same jet #'s.

but what would i know, i have FAST cars.

[Superalty]

It is apparent you don't know shit. If I take Tylenol does that make me a doctor? Of course not. Just because you have a "FAST" car doesn't mean shit. So instead of running your mouth why don't you toss up some dyno's of your said 50-60 whp increase using similar jet sizing? Maybe then we will give a fuck about your relentless babbling.

And next time someone makes you look like an idiot (which is not hard to do) because you don't have a clue, why don't you unplug your computer and hang yourself with the power cable.

i should hang myself because im right and you're wrong? :wtc:

nos jetting will give you crank hp, nx jetting will give you whp, tnt jetting will give you whp+40-50 hp.

the jets will have the SAME #'s on them, but the companies drill them according to whatever they want.

say you have a lt1, and you put nos .62n .35f, you'll get 150 crank hp, then you put NX .62n .35f, you get 150rwhp.

now, is it because NX's jets are "better" or they just make a larger hole with the same # on the outside?

keep playing around with your 50 shots and ill keep running XXX with stages.

dont feel bad, its ok to be wrong and learn a thing or two. :naughty:

hmmm lets see hear. MY stock whp is 150 so yea lets see how fast i can fry a piston in my DAILY DRIVER YOU FUCK. I know they arent better, but they make whp and i know which ones to use to create that hp not just punch my self in the nuts and choose two jets like i assume u do. :jerkit: , jesus i hate getting in arguments online. f'n pointless.

[sparky]

my stock wheel hp in the coupe was probably 160ish, its now making well over 4xx hp and 5xx tq with BONE stock internals. btw the motor was made in 1990 and has 86k miles.

;)

one day you guys will learn.

i also DD what i race. ;)

[ze doktor]

rich runs bigger shot than that in his sonoma. shit homie, people with 1.6L civics run a bigger shot than that, bone stock motors.
