I was looking around in performance catalogs and i saw a dry shot kit and it plugs into a "Air Ejector Amplifier" its basically a Nitrous Shot to your cold air intake filter

 

For some reason, that doesn't look like the safest way to go lol.

 

you're talking about the first item in this link

http://www.zex.co.za/accessories.html

thats separate from the dry kit btw...but u should just stick with a wet kit...its safer

 

wet kit only

 

the biggest issue with those things are the damage they do to your maf sensor... even if you replaced the nozzle on it to a wet, you'd still be shooting n20 at your maf...

 

do not use dry kits, spend the extra money on the wet kit for safety. also im not sure how well a 74 shot will do on an untuned car, the cobalt isnt really a good candidate for nitrous right now imo due to us not have special tuning tools yet to have a program for n/a engine and a switch for a program to a nitrous engine, when that becomes avialable then it will work, for now i wouldnt go above a 50 shot and even thats pushing it.

 

I ask cuz their's a shop nearby where i live called Humble Performance and they said it would be "safe"

 

WTF?

A. how would a 2.4L running a 75shot differ from any other car? Look at the number of 2.2guys with 75shot, and we have forged rods.... if anything a 75wet would be better at home on the 2.4L

B. you dont need a "tune switch" to run a wet kit. what would you be changing? AFR? Thats what the fuel jet is for on the n2o kit... timing? hp tuners is all you need....

"imo" was the only true part of your post... because there wasnt any facts there..

 

So your saying that a wet kit with a nozzle in the intake cone on the 2.4L will go good?

 

it just doesnt seem very safe to me

 

sszero, the thing pictured above is bad for your maf sensor.. maybe in a few months chris@hptuners will unlock our VE table and we can go SD/maf-less... but until then you should go direct port injection or a normal wet nozzle into the intake tube before the thottle body...

one note of caution, start small (get extra jets) and read up before you do it...

 

ummm the jets are the same for every car. they are not rated seperately for 4/6/8 cylinder engines. running a 75 shot will be safer on a higher displacement engine with same grade internals. do you think a 125 shot would be safe on a 2.4? well it's fairly safe on a v8 and there are multiple 6's on the mustangforums running 100 shots. i personally would not run a 75 shot without a tune on any 4 cylinder engine, but obviously you seem to know so much about nitrous thinking that a 75 shot on a 4 cylinder is just as safe as 75 on a v8...ha you are funny.

 

wrong and wrong.

I didnt say anything about v8 or displacement, i said 2.2's dont have the forged rods like 2.4L's.... but i wouldnt expect a mustang owner to understand how an engine works....

However since you brought it up, nitrous jetting _IS_ rated differently for 4 vs. 8. maybe you should have purchased a chevy... your IQ level suffered a bit..

however, if you'd like to be the smartest ford owner in the world, please do take a look at the following urls..

I am new to this forum and have recently picked up a 2006 cobalt ss. So far I have done powder coated exhaust manifold, H&R performance springs, Z rated rubber, LED undercar kit, 35% tint, and have order the Zex 90 shot wet nitrous system. I have yet to do a cold air intake and was wondering where the best place to find one for the best price is. I have also noticed in the last month or so that the 2.0L sc has a lot more parts. I believe there is no replacement for displacement, so when are all of our goodies going to be released. I bought a second car yesterday so I can concentrate on making this cobalt crazy fast!

 

nitrous jetting is done by fuel flow, not the amount of cylinders in the engine. let's take a look at your statement shall we? the 2.4 will naturally have more fuel flow than the 2.2 which changes the jetting estimate. Jet hp estimates are no where near exact, they are just that, estimates. now, you said something along the lines of, "why would running a 75 shot be any different in a 2.4 than any other engine?" well since the jetting is done by the amount of fuel flow per cylinder vs the amount of nitrous, a 75 shot on a 4 cylinder engine will divide the stress among 4 cylinders. on an 8 cylinder it will divide this stress among 8 cylinders thus making it safer, and less stressful. those charts you posted, are estimated levels that give you reccomended jet sizes for different displacement engines. Now say i have a large v6 such as my 4.0. i would get better gain estimates using the jets that zex reccomends for a v8 because their estimates are closer to my level of fuel flow because of my high displacement. Now if you would like to argue this, please take a few classes at michigan techs summer automotive engineering class. i've been doing this for the past three years, and it seems to help a bit

 

wow and you don't think a tuner would help????what the **** do you think hp TUNERS is?!

 

How does anything you've said so far counter anything i've said? It sounds to me like you've realized your mistake and are looking for ways to back out of your statements. Your statements where "Jetting is the same for every car" AND "they are not rated separetely for 4/6/8". Now you've agreeing with me that jetting is rated differently? Hmm...


... in the context of cobalts, keep reading, i compared a 2.2 to the 2.4, not a v8. Why? Because this is the cobaltss forum!

Your agrueing a pointless debate. Its safe to assume 99.9% of all v6's and v8's will have higher volumes of fuel. If you take a set of jets that are rated for 75hp on my cobalt and stick it on your car it will produce less to the wheels, less esimated rating. how about that, see how that works? Its rated at a lower hp, CRAZY! so its RATED DIFFERENTLY.

Lets say that one more time without the sarcasm so you get it. Jetting is rated differently, a 75shot would be like a 45 (guessing) on a v8. period, end of discussion.

obviously money well spent. No thanks, i'll pass on the "summer adult learning center next to joe's bar" education.

wtf are you talking about ? re-read my post without the emotion and estrogen and it will become very obvious... The guy i quoted was talking about a dash mounted "tune switch".

Your reaching for **** to fight about... so why dont we take this to PM or a track?

 

Just run a 75 shot wet kit, its "safe" for the engine.

 

noooooooo you are misunderstanding. All jettings are created for certain levels of nitrous for certain levels of fuel. They are not rated differently for different size engines, those charts are just estimates, but anyway you seem to know that. what you need to realize is that your first statement (the one i argued) was very vague and very ignorant and would be taken the way i took it by most if not all people that read it.

A. how would a 2.4L running a 75shot differ from any other car? (same way a 150 shot is going to differ, it's going to be safer on a higher displacement engine which was pretty much entirely what my post was saying) Look at the number of 2.2guys with 75shot, and we have forged rods.... if anything a 75wet would be better at home on the 2.4L


B. you dont need a "tune switch" to run a wet kit. what would you be changing? AFR? Thats what the fuel jet is for on the n2o kit... timing? hp tuners is all you need....

when he said tune switch, i think he meant (at least the way i understood it) a new tune like a switch in tunes. which would be a very VERY good idea with a 75 shot on a stock 4 cylinder engine. maybe i took your statements the wrong way, but if you re-read your own post it is very obvious how i took them that way.

 

75 shot is too much to run as a dry shot on a 4 cyl engine.

I running a 50 wet shot and thats doing fine with the stock timing, a 75 shot will require some timing to be removed per the zex instructions it's 4 degree, so you do need to change the engines "tune" with nitrous.

IF you were building a race car that was for the track only a dry shot and a modified PCM calibration could be very effective, but if you want to put it on your street your drivability would suffer.

 

yep, thats pretty much what i was trying to say as well...

 

just to clarify for everyone, nitrous is jetter via your fuel pressure at WOT, if a 4 cyl has 45lbs of fuel pressure at WOT and so does a V8 the jetting is the same for the same shot. but i run a 75 wet on my SS/SC and the plugs look awsome, remember the SS/SC is tuned waaayyyy rich right out of the box, i dont know about the 2.4 or the 2.2 but ive been spraying my SS for about 4 months and its doing fine.

 

The 2.4s have forged rods? pistons too?
