added HP from Injen intake?

[srwong]

i tried using the search button, but nothing for our cars came up, i know there's a thread somewhere about this.

but how much HP does the INJEN intake add to a 3.5 coupe?

[Beak]

on our stock set up. not tooooo much. maybe 4-6 at WOT

[Beak]

maybe 8 or so in the winter

[srwong]

really? i read on this site that it was +12

Well come on, you know better than to believe the seller. Of course they'll inflate their #s to sell their product. Would you consider buying it if it said "+5 hp +6 tq?" for the same amount of money? Probably not.

I'm sure the real #s are somewhere between 0-30% less than what they claim, if not down right zero. As discussed to death in another thread, some SRI or WAI or whatever you want to call them, do nothing but suck in warm/hot engine compartment air, nevermind the metal tubing getting hot, which would probably be worse power than if you were to use the stock intake with some mods to it.

To be honest, you probably won't notice a change at all...I know I certainly didn't. Oh sure, the sound you get from it is absolutely orgasmic, but power gains are limited to you imagination I'm afraid. Several others in the Nissan community have also noted just how efficient the OEM airbox tends to be...

Honestly, I got mine solely for the amazing sound!

[blackteam02]

yea Wong, the gains are not 12+, well it doesnt feel like it anyway.

as for the sound it makes, haha, i dont know what the big deal is. i mean the intake just makes a quick inhale sound(not even that loud at all). . . so i dont know what everyone else is hearing but it does not sound "good/badass/orgasmic etc.", it sounds like an intake breathing. haha!! so i guess thats a thrilling sound, i dunno.

[CoupeVQ35CVT]

Actually, at least in my Sentra, after installing the after market intake, the car overall had a louder growl to it under load, aside from the very brief "breathing" sound you hear when you step on the gas.

[LinkNuc]

Maybe 1 or 2, in real life. Don't get me wrong, I have put SRI and CAI's on a number of my cars, I like the noise you should hear the 5.6 on my old Titan ROAR..but yeah 1 or 2 maybe

[marvin5087]

stillen had dyno'd i believe 10.5 or 11.5 hp gains by the injen with mr technology

[srwong]

stillen had dyno'd i believe 10.5 or 11.5 hp gains by the injen with mr technology

yea see, that's what i thought. that's what i have, and what i've read have said +10hp or a lil more, but sure not like 1 or 2

[gearhead05]

but power gains are limited to you imagination I'm afraid.

I hear this so much on these forums, but I can say without a doubt that I most definetly DID feel and notice the power gains from my intake. It was not in my imagination. I also took my brother in law along with me after we first installed it and he, someone who doesn't ride in/drive my car said he could feel the difference from the "before" test drive we did around the block.

[dldjros69]

Here is the deal, i have heard both sides.

Cooler but less air from outside the car - stock air boxWarmer but more air inside the engine bay - wai

The Bully Dog Tuner measures air intake temperature. Id like to see a stock air box vs any wai. To see if there is a drastic difference in intake temps.

I hear this so much on these forums, but I can say without a doubt that I most definitely DID feel and notice the power gains from my intake. It was not in my imagination. I also took my brother in law along with me after we first installed it and he, someone who doesn't ride in/drive my car said he could feel the difference from the "before" test drive we did around the block.

so did I... after i installed it i could definitely feel a difference in power

[mikegtr06]

i felt a difference.... could be placebo.... there are numbers i like to think that they are not lying... so im going to go with +10 hp from intake... and if you dont like it GTFO of my internet

The important thing is that you are pleased with your intake purchase. That is all that matters. After all, it was your money that you spent.

Why would anyone think that a manufacture would inflate alleged performance and horsepower gains? I have never heard of that happening.

I think that you should go with at least +15 hp from your intake.

Don't take this the wrong way, as I do like it, so I do not plan to GTFO of of "your" internet.

And all this time I have been led to believe that Al Gore was the father of the internet.

I do have a few questions for you.

You are aware that the A/F ratio is computer controlled?

Adding more 'air' to the air/ fuel ratio will only make the computer adjust it to preset factory numbers. You will not have more 'fuel' added to the equation, therefore, no more horsepower.

Are you under the impression that your engine is starved for air with the factory airbox?

^^ Dude, seriously...does it really make you feel that much better about yourself by belittling others with your poorly judged "sarcasm"? Your posts are increasingly troll-worthy. Go crawl back under the rock from whence you came...

ESP,

I am sorry that my posts are not quite up to your lofty standards. I do feel better pointing out, and making sport of, ridiculous and asinine comments posted by people AFTER they were given helpful, accurate information.

Lets look at this post as an example. The question was asked if hp was added if an aftermarket intake was installed.

CoupeVQ35CVT said “ I'm sure the real #s are somewhere between 0-30% less than what they claim, if not down right zero.” Good advice in my opinion.

LinkNuc said “Maybe 1 or 2, in real life….” More good advice.

I also thought that your comment was great. You said:

“To be honest, you probably won't notice a change at all...I know I certainly didn't. Oh sure, the sound you get from it is absolutely orgasmic, but power gains are limited to you imagination I'm afraid. Several others in the Nissan community have also noted just how efficient the OEM airbox tends to be…”

Your comment was not only informative, but it was also factual.

However, when mikegtr06 said “i felt a difference.... could be placebo.... there are numbers i like to think that they are not lying... so im going to go with +10 hp from intake… and if you dont like it GTFO of my internet.”, that is when I decided to post a rebuttal to his comments.

So he is going to “go with +10 hp from intake…” While he is fantasizing about hp gains, I told him to dream bigger, and go for 15hp from his intake. Why stop there, I asked. None of this this is based on scientific testing is it?

I agreed with him when he said “ “there are numbers i like to think that they are not lying..”

When he boldly stated “and if you dont like it GTFO of my internet.”, well, that was a challenge for me to spring into action. He became fair game. He is inviting rebuttal.

I have a hard time believing that the internet is own property, don’t you find that claim to be just a little over the top? What is ‘his’ internet? I thought that it was ‘our’ internet.

Knowing that you like me to base my comments on facts, here is the Al Gore quote:"During my service in the United States Congress, I took the initiative in creating the Internet" Gore said during an interview with Wolf Blitzer on CNN on March 9, 1999. The internet as we know it today was started in 1983.

What is with his “GTFO” comment? I have no plans to leave. I am having way too much fun, and learning things I didn’t know, all at the same time.

Tell me what is incorrect about my Air/Fuel ratio statement. If I am wrong, I will correct it. Notice I am talking about a stock vehicle, without the addition of a ’tuner’ that allows modification of the pre-set factory settings.

It is always easier to attack the messenger than to refute the message.

[dldjros69]

Ignore this douche he will go away.

[LinkNuc]

I don't think he'll go away or he should. We need candor on this site, allbeit a little crass. I can't believe people get so upset. And to be honest in all these debates, Throck has backed his point up, while others resort to name calling. Hey, I've put intakes on my Z and Titan, there is no noticeable difference in feel. There is in the look and sound.

[dldjros69]

Its not the fact that he is or isnt making good points. Honestly some of the things he says is correct.

BUT ITS THE SAME S**T. intakes and bully dog. We get it we understand.

THE MAIN THING IS - He comes across as an @sshole. He isnt friendly, its sarcastic and rude. We arent in jail here, there is no need to be a prick about things.

Also i dont know what crawled up your butt lately, you havent been the nicest either. sorry 2 call you out but i dont always remember you being such a jerk.

Thats just my 2 cents

[ESP]

Throck,

You obviously enjoy antagonizing people, and you know you're being a d!ck about it. By now you've certainly earned your well-deserved reputation for it (in 58 posts no less). Does this boost your ego? Yes? Well good for you then. Enjoy what I can only assume must be a very lonely and/or shallow life in the real world. As I mentioned in another post, I can't imagine anyone with half a personality being able to spend much face time with someone like yourself.

Your facts are, for the most part, correct. It's your delivery that's lacking. But of course you know that. You enjoy this awkward, off-putting persona.

Remember that modding a car is supposed to be fun. Who cares if someone thinks they gained 15+ HP from adding dental floss between a pair of random bolts in their engine bay? Sure, you and I know it's ridiculous, but if they want to spend the money on it and they're happy with it in the end, then why cast your endless bombardment of negativity on them?

When all is said and done you may be "right"...but you're still a douchebag.

Oh...and the Internet as we know it began in '82, not '83.See? I can be a d!ck too...

[CoupeVQ35CVT]

This is too much fun. I can't believe people start taking his stuff so seriously. Lighten the h311 up already folks. If nothing else, his posts are a good giggle.

The dude's offering an opposing argument, and the best I see is people getting pissy and calling him names and a troll. Maybe if someone can debate him in his language.... that of facts based on... facts, and slap him around a bit, he'll go away then huh? Instead you all get pissy, feed him more and well the cycle continues.

I don't know. Just a thought. So it's settled, the gains are nominal, and at best just be happy your already great car sounds that much nicer. That's it.

Here is the deal, i have heard both sides.

Cooler but less air from outside the car - stock air boxWarmer but more air inside the engine bay - wai

The Bully Dog Tuner measures air intake temperature. Id like to see a stock air box vs any wai. To see if there is a drastic difference in intake temps.

+1. That would be interesting, and put this to rest.

HEY SORRY IF MY POSTS HAVE BEEN A LITTLE CRASS LATELY. I TOO FIND THIS KINDA FUNNY HOW PEOPLE GET SO BENT OUT OF SHAPE ABOUT THE LITTLE THINGS ON A FORUM. IT COULD BE WORSE I COULD BE TYPING IN ALL CAPS. THAT REALLY MAKES PEOPLE MAD.

lmao

DAMM SKIPPY FOO. DAM I AM SO MAD WHEN PEOPLE GET ALL PISSY, I WANT TO EAT.

[maxentropy]

Seriously, all you folks with a 6MT -- DYNO before and DYNO after a mod. Subtract the whp and that will approx your "gains".

I would but I've got CVT and honestly, who gives a s*** exactly how many hp an intake or exhaust getcha.

Enjoy the sound and don't worry about a few hp.
