maybe that's true, but for the driving I do... I don't need the intake, I much rather my car be quiet.. whuen i put the stock intake back on my dad couldn't even hear my max running..

 

Ok ok, there's nothing to be all steamed about.

Fact of the matter is, any intake mod yields to only about 1 - 2 hp gain. We're not going to start another intake argument about that, because this forum is saturated with such topic. Like I said before, intake mods depend on one's application. In my case, I feel that my car is more responsive with the modified stock setup. Many found the same true, why would they make it up? If you really want dyno results, pay for mine. I'll be more than happy to do it. And IMHO, its not worth the dyno money to me only to verify that the gain is that minimal. We already know its that. What I do find humorous is that people have spend $$$ on a mod that will only yield very little gain.

 

Really? You can take 5 dynos in a row with the same car, same conditions and all of them will be different by a hp or two, maybe more. When testing intakes that are all within 2-3hp of each other, a dyno seems like a waste of time to me.


Doesn't mean jack unless all dyno runs were made on the same MODEL dyno machine. I'm sure the ones you had made were on a dynojet and a mustang dyno.

 

No Davi, the CAI didn't make you drop a second off your 1/4 mile time. It was practice and experience. I'm putting on my stock intake before we hit the track this week and I suggest you do too. You'll see how much better it feels down-low, especially with your automatic. It's not really an issue with manuals.

No, you're wrong. You lose top-end and compared to stock your lowend is the same or weaker. With the hybrid you gain top-end compared to the stock or CAI but lose low end.

 

I've never taken my car to a track but I know when I felt my car run a lot better and have more pull than before.

 

From what dave sz is saying, its my opinion that a hybrid intake is good because when you do spirited driving or race, you tend to keep it above 3.5k rpm, even in an auto. I personally wouldnt give a flying fukc if i lost bottom end because i would still have sufficient amount of power to drive around the city. When i want to accelerate fast, i just floor it and enjoy the sound/added power of the hybrid intake.
Please correct me if i'm wrong.

 

How does your car run during really hot summer days? My HAI made my engine bog down badly. My car lagged. This is why I went back to stock. During the winter to spring season, it ran fine.

 

I lost my low end with my cai, and it was sitting in the fender.

 

nah dave, im telling you. with the same 2.4-2.3 60' times, i was running 16.4-15.9(one time). now i can pull 2.5 60' and get a 15.5 And ill bring my stock intake, and maybe we can hit it up. i dont even have a panel filter anymore. I've considered using my stock resonator, but well see at the track. Try em all out since it seems like we'll have an abundance of runs we can get it.

was this your butt dyno telling you this l3ftonm3? not saying you're wrong, but just from my track evidence alone, that told me the cai helped out a lot.

 

as i stated earlier. the highest point on the power curve doesnt mean that the car will be faster. for exmaple with the stock intake might have a lower top hp, but the curve will be more level, and a CAI could have higher numbers, but this is only at higher rpm.....get what i mean? more power doesnt necessarily mean the car is faster. considering when we race we are usually above 3.75 rpm whichever intake has better power at higher rpm should be faster.

 

both dynojet, and that was my exact point. dynos can lie.

 

I have tried numerous times at the track to find out which intake is best. The stock intake feels better and isn't loud which i prefer. I have proven to myself that my place racing intake is the way to go though. I have always ran faster times with the pr cai over any other intake which includes any variation of stock with ooglie, stock with hacked lower box,hai.I do however run the stock resonater with the pr cai. I still have to see if this is better or worse than the pr midpipe

 

that was going to be my next set up. the stock resonator with the pr cai. how does that feel? is it quieter than the normal PR set up? do you have any pics of the way you did this?

 

I would say that the stock resonator is helping your CAI a lot especially at the top end. The resonator acts as a buffering device.

 

Stock resonator makes a world of difference, especially in low end throttle response with the rest of intake cold air. It also gets rid of that sucking sound, you can have a CAI sleeper intake. Like I said before CAI is a benefit if you run at high speeds/race. For everyday driving or stop and go stock seems better because of quicker throttle response, its ugly, but it's better. So it does all depend on the way you drive.

 

Now why would you say that when it was shown before that the CAI is weaker in the top-end cause of the long tubing.

 

so are you saying that i should have the resonator(under battery) connected or not? right now i just took out the elbow peice that connects the resonator to the snorkel pipe.

 

You must have had ample opportunity to accelerate fast during the 71 miles you've driven your Maxima in the last 4 months, lol! That is, up until the 150 miles you drove this past weekend after I chastised you for not driving your car enough.

I thought you were supposed to be studying for exams this week, lol!

 

CAI is known to give a lil loss on low end and gain on high end, so for the avarage driver the stalk intake is better becaouse most ppl, esp on the automatic dont bring it up to 5000 RPM, But if your an agrassive driver with a stick you will notice a difference at 5,000
RPM.

 

People, listen to Dave ....


Oh yeah and It's stock ... not stalk , and your wires are crossed you have it as.s backwards ....

 

It was shown that CAI benefited at speeds closer to 100mph, you lose power in the low end with CAI. Any professional street racer running all motor usually runs CAI. Even with stock or CAI on a maxima you gain nothing after 6000rpm.

 

Sorry, I meant midpipe.

 

Again, no. Out of the billions of threads about intake comparisons, all the ones that say "If you want to retain your low-end and not lose it like with the hybrid, buy a true CAI, PLACE RACING. Never have I read anyone with any knowledge say that a CAI is for top-end.

 

are we arguing that a cai is a benefit or not? maybe this is a stupid question but just like exhaust, less bends and a bigger diameter make air induction easier and airflow in greater quantity, right? maybe on a stock maxima it is not a real gainer but what about those of us who have numerous bolt ons? i got a full exhaust, headers, flywheel, udp, plus other bolt ons so my car will use more air than a stock max. i think that the cai is beneficial for me.

plus, those of you saying that the injen isnt a true cai...i have an injen "style" intake i got off ebay for $40...it hangs below the radiator and today i tested it w/ a scan tool from my shop and it never went above 84degrees except when stopped at a redlite. it was 81degrees where i live today. so i feel mine is a true cai.

 

the pr style CAI is below that. it kept an ambient temp somewhere in the 70s. it kept a cooler temperature out of all of the intakes. short ram, injen, and CAI. And Dave is right, a CAI will keep your low end. Which is why ill keep mine since the 00VI will give me the top end i need.

 

Professional street racer....

 

iono what you guys are talkin about but from my understanding, CAI is better for your low end, not the other way around. CAI offers cool air immediately as opposed to sucking up hot air under the hood with a short ram or injen, thus improving throttle response and letting you retain or giving you better low end power. HOwever, at higher speeds, due to all the tubing and the bends, the CAI isnt as good.

 

The resonator that we are talking about is the one right before the TB. IMO, the resonator under the car battery does nothing but make the intake quieter. This is just a theory and I will be eliminating the elbow from the snorkle and that resonator. Then I will get another pipe and extend it from the snorkle (where the elbow used to be) to back of the front bumper where it can get some cool air.

maxgtr2000,

The midpipe is the aftermarket replacement of the intake resonator. The stock one is called the intake resonator, the piece that takes the place of that found in most aftermarket intake kits is called midpipe.

 

I agree with egxflash and Dave Sz, the CAI benefits you on the low end, at the top it runs out of breath due to the long intake pipe where air has to travel thru. There was a PR group deal in the 5th gen classified a long time ago. Many who have purchased them, were complaining that their Maximas used to top at a higher speed before the CAI. With the CAI, it reduced their top speed, the intake was simply running out of breath! Many were dissatisfied with this. I don't know what happend after.

Dave Sz, were you the guy that did a test of all the different intake setup in the track a long time ago??? I remember how lengthy that thread was but it was certainly a good read and I have learned alot from it. Those who think that the CAI improved your top end, you guys are being delusional....sorry to say.

 

Okay, I'm friggin confused now. I'm considering getting a Y-pipe. I was told that Y-pipe plus intake could get me 20 hp or about that. I drive a 5spd and I keep my rpm's up every time I get on the interstate. I don't get to 100 too often but I get to 5K RPM all the time in 4th gear around 80 before I shift to fifth and keep it at 80. And then passing in 3rd, I do that alot. What setup would benefit me? BTW, some dude mentioned he had HEADERS. I read on the org faq that no header setup gave better gains than stock. Is that information outdated? Have there been headers designed that do better? I mean by like more than 2 or 3 hp?

 

Dang your car must be guzzling a lot of gas driving the way you do. I'm working my way up to getting me a Y-pipe. As for intake, modified stock airbox is the best for me. But I have a totally different driving style than you. And because gas is so expensive now a days, I try to limit my 80mph runs on the freeways.

 

Well, I have tried light-footing it. I shifted around 2500 to 3000 rpm every time and took it easy on the hills and all that and my mileage didn't get much above 22 mpg. I usually get around 20 with straight city the way I drive. Mixed, it may go up to 22.5 to 23. I've never been far over 25 on the interstate. But then again, I've never been able to keep my speed constant, or below 80 mph with either the windows down some or the ac running. Also, I constantly have to slow down and speed up again cause people want to get in the left lane and slow me down. Why do people think that if they get in the left lane to pass someone that's slowing them down that I want them to get in the left lane so they can slow me down?? Left lane should have priority. If someone in the outer lanes wants to pass, they should wait until the faster people in the left lane pass. Even if that means they have to slow down or break their cruise speed (which I HATE, cause it screws up ma gas mileage), they should do that. That's the way I do when I'm not in the left lane.

 

Driving in up and down hills won't help gas mileage at all. Light footing it to me is shifting at 2k rpm and no higher. I go about 55-60 on the highway and get 26-32 mpg depending no how rambunctious I am when getting up to 55 - 60

 

Okay I hate to be getting off topic, but if I shifted at 2000 rpm my car would fall asleep.

 

Alright so in conclusion...
Is it true that stock intake gives me quicker launches because torque is better?
An aftermarket would give me more power above 3000RPM?

Because I'm still thinking of getting a Stillen Intake (No Injens...too much trouble for me. I live in Canada and snow can get quite deep) but after reading this post, I don't if I should. Usually i drive around the 2000 - 3000RPM and my Maxima is auto....

I would just like to know if I should spend the money on this mod?

 

I shift between 2000~2500rpm for daily driving.

 

Stop and go kills fuel efficiency. In Los Angeles, this is a way of life and I rarely do highway driving, mostly street. I also light foot it as well. I get an average of about 24 - 25 mpg. I avoid driving up Hollywood hills are any hilly routes at all costs. I have no business being up in the hills anyway.

 

Why would you say that?

 

dude, resize your sig. its massive

 

i do the same..n at times i go 5000rpm +..full tank...this week i got 347 miles before i gas up =]..i was using mobil gas 93..back to BP since there wasn't any when going down to SEMA...BP way to go! lol

but yea..i do feel a bit more power with the injen intake.. hitting around 5k rpm(stick shift)...but i'm going to go back to the stock set up and use my 8in K&N cone filter like what i have on the sterling mist(auto)
