Got my 07 3.5se 6mt dynoed

[mcheddadi]

See, I told you earlier...I got 291 horsepower with Sunoco 94...and you think that is not realistic......also run the dyno on a cool day...

Plastics08 3.5SE Premium Black Coupe

I noticed that too, yesterday it was like 40 fahrenheit (4 Celsius ) and the car seemed a lot more powerfull, the sluggishness around 800rpm to 1500rpm was gone and the acceleration was a lot more linear up to 4000rpm where it felt like I was going into the star trek space warp pull lool. I think my next mod is going to be a CAI until that sweet turbo setup comes along, then its a full turbo-back 3inch setup. hahaha

[audtatious]

The question would remain: Would you notice substatially higher power in those conditions with an aftermarket intake over the stock setup?

Hmmmmmm.....

[Ormand]

Are you kidding me?!! You actually believe you're going to get 12WHP from a short-ram intake??? I speak from experience, not some inflated claims made over the internet. Let me know when you come back to planet earth, then we'll talk.

We have to guess that your experience has been somewhat limited. ANYONE who knows anything about engines knows that:1- Horsepower gains from an intake (or exhaust) depend on whether the intake (exhaust) being replaced is restrictive and the degree of restriction, and 2- The gains are dependent on the power of the engine being modified.

IF you have experience with weak, small engines, with relatively good intake (exhaust) then you will have seen only small gains. But if you read magazines, you will know that bigger, more powerful engines have been tested by many groups, NOT just manufacturers, and found to give substantial gains. Gains substantially higher than 12 hp were found by independent testers, on dynos, and verified by track tests. The Altima V6 has a lot of power, and the intake is clearly very restrictive. This has been discussed, over and over, but apparently some people don't have enough gray matter to absorb these FACTS.

Yes, for that HUGE 1.62whp increase the NPM article shows on their dyno sheets (SE-R Nismo intake test you have pointed out) really makes things crystal clear.

Don't go throwing cold-test numbers against warm-test baselines and expect everyone to take your word for it.

[AZhitman]

Grey matter, huh?

Careful son, you might get taken to school here.

Spend a little time researching the volumentric efficiency of a Nissan intake system. Build your own manometer. When the smoke clears and the mirrors are put away, the bottleneck is NOT in the intake... it's at the head.

By the way, I've done back-to-back dyno pulls that showed a 20-whp variance, and the only change was, I picked my nose in between.

Spare those of us who actually BUILD cars from your preaching - I don't sense any grease under your nails or a multitude of engine modifications in your past.

[coreansurfer]

You have an S14, why bother upgrading a car designed for secretarial use?

Door swings both ways

because s14's have aftermarket support that goes beyond an i/e/h system.

That is true and aftermarket support is being developed for the Alty coupe as we speak

[SHIFT_COUPE]

Glad to see nobody got too bad of a beat down in here I'm gone for a day and this thread turns into an intake debate again. Gotta love it.

Funny thing is, its the same people with their heads up their asses.

[generic808]

I'm not Ormand, I'm the same Dexion from nissanclub. Well If they are lying about the dyno charts cutos to them. But everyone who says they have a WAI for the 4th gen 3.5 says they can feel a good difference on a butt dyno. I doubt they can feel 5-8hp like that.

And yes I do have a 3.5 but haven't gotten an intake yet, prolly gonna go with Injen.

If you read back threads, I believe I was the first one on here to install the INJEN intake on the 4th gen. I was the first to say that there was a noticeable increase in throttle response, I didn't say horsepower. Nobody can tell the difference in 5-12HP with their butts because many different variables would become involved.

But now you come along and say the FUJITA will give you 12HP AT THE WHEELS?!! Let's just end this thread here and we'll wait for you to actually buy your Fujita and install it. Make 3 runs on a dyno and post your numbers. IF you get 12WHP, then like I said before, I'll be the first to admit that I was wrong. And that's IF you ever even buy your intake. And if you need help with installation, don't be afraid to ask

BTW nice sig Tyler!

[SHIFT_COUPE]

Thanks Eric

Careful with the dyno bet. You can fudge those too

[generic808]

Yeah I know, he'll probably set it up in an 50 degree air conditioned room with 3 industrial fans blowing on his OPEN hood. Not "REAL-WORLD" gains. Just those exagerated, inflated manufacturer claims. I wonder if this guy has a vested interest in Fujita? Who knows?

[AZhitman]

...if I find out he does, I have a contact for their marketing department, and I'll be certain to send them an invoice.

[Dexion]

You guys have way too much time on your hands, if I ever do get a chance I will do a before and after dyno run, weather is getting colder here now so chances are numbers will be fudged. I somehow doubt it will even matter to you guys if there's a difference in 12whp.

[edit]hey generic grats on becoming a mod, now maybe you'll stop the pety flaming?

Dexion, you're still at it, huh? I give up already! You actually believe you'll get about 14HP at the crank from an intake, then so be it. It's not like those numbers will really matter on the street because real-world performance and a mocked up dyno run are two VERY different things. Many factors come into play when you're on the road vs. being in a controlled environment.

You win. You're the man!!

[audtatious]

If you do this, I suggest the following.

1. reset the ECU2. perform a cold-run (engine cool to touch), then a 2nd (back to back) run3. swap intakes4. reset the ECU 5. perform a cold-run (engine cool to touch), then a 2nd (back to back) run

The reason for #1 and 4 is to reset all the "learning" the computer has done with the factory setup and is at "default" for both sets of runs.

Those results would be interesting to see. Wish I had a dyno to play with or I would do it myself using a VQ35DE with both a Injen intake and the factory intake.

[07wHiTE 3.5SE 6sPD]

thanks for all the input.... it was a dynojet and uncorrected power... the corrected version was 249 whp..... i found that rather remarkable with the 261 whp wit intake and grounding kit..... especially on a dyno dynamics..... thats usualy around 290 - 300 wheel on a dynojet from my experience...... probably i have a defective motor...lol....

[Dexion]

hey man post up some videos of how your altima sounds

[07wHiTE 3.5SE 6sPD]

i will definitely see if i can make some vids..... its pretty quiet....compared to my cuzin's g35coupe wit the cold air alone.... that thing screams.....for some reason the gcoupe oem exhaust seems louder than the stillen setup.... have a great weekend guys

[audtatious]

probably i have a defective motor...lol....

Not "defective" . I have seen factory "godzilla" motors in stock cars that make better performance than others. Engines built on the same assy line will always have somewhat different performance potential regardless of them being built at the same. Parts always have a spec-range which means there are some occurances of high-spec parts all making it on the same motor during the manufacturing process.

[Ormand]

Aww yes, that is the thread! Dexion, are you this Ormand fellow? I'm gonna go out on the limb and say that you're the same guy, just with a different SN. Seems like you pissed off a lot of people before and you're at it again. Funny thing is, if it is you, where's your intake?!!! You still don't even have one??? You come on here talking all this nonsense and you didn't even do anything to you STOCK Altima!! Or do you even have an Altima?

Hmm...

Generic, you're pretty clueless on almost every subject. Do you have someone to help you get on the internet? When you have something useful, and intelligent, to say, it will amaze us all. What did you to do to get to be a moderator? Did it taste good?

For your information, Generic has provided many useful suggestions and loads of advice/help to numerous members on these forums. He is very knowledgeable in several areas and is a pleasant guy (or so it seems on the net). Please do not revert to saying such unnecessary comments. Even if someone is wrong, you have to remember that everyone makes mistakes. Some people on these forums have had outrageous claims about horsepower gains and have not had any substantial proof to back up their own claims. I am not saying this is or is not the case in this thread, I am just asking you to respect Generic (as a moderator and member) and other users as well. We are all Altima enthusiasts here and should behave as such.

[audtatious]

You are such a winner aren't you? You come on here making statements that we don't agree with and result to trying to bully people?

Class act you are

A little quote from you, Ormand:

"The hp gain with the Injen, or a Fujita, will be about 10 or 12 hp. Some people say "Oh, it can't be that much", but those people forget two things. One- the new Altima makes substantially more power than previous Altimas, and the gain with an intake or exhaust change is greater when the engine makes more power. Two- the stock intake on the new Altima is pretty bad as far as air flow is concerned. If you know anything about air flow, all you have to do is look inside to see how bad it is. It does muffle the noise, though. Other engines, in other cars, may gain even more than 10 or 12 hp- but the V6 in the 4th gen Altima will only gain about that much."

Haha Omrand, Ormand, Ormand! Me, clueless? Now if you read your on words, it seems that you would be the one who is clueless. You keep saying the stock intake is "pretty bad as far as air flow is concerned." Now let me ask you this because myself and I'm sure many others would like to know...HOW DO YOU KNOW? Did you EVER even look under the hood of your car beside to refill the windshield wiper fluid? YOU DON'T EVEN HAVE AN INTAKE yet you still talk all this smack. Go ahead and purchase one and remove your factory airbox. You'll see that it really isn't a restriction; it's just a black box with a inlet and outlet. There is no restriction, really; at least not 12-14HP worth. The air flow will not be hampered much by this black box we call an intake. You know, the one your "imaginary" Fujita replaces.

So next time you decide to refill your windshield washer fluid, take a look. Oh yeah, you open the hood by pulling the hood release lever located on the lower left hand side of the drivers compartment. If you need any help with the installation, please refer to the little tutorial I posted a few months back. I think it'll be very helpful for you because there are a bunch of pics

BTW I'm done answering you. You should just take your GREAT mind and enlighten everyone who will listen to you because I sure won't. And I hope many others won't either. Have a great life! And good luck with the installation of your imainary intake

[audtatious]

You will have to wait a week for a response at this point...

[generic808]

I'm done with this fellah.

[audtatious]

I believe a number of us (members included) are. Open conversation is what we stive for and simply performing personal attacks are not.

BTW, you got mail

[SHIFT_2.5S]

Members like that truly detract from the purpose of these forums and should be dealt with accordingly.

Generic, don't mind his childish comments and certainly don't waste any nerves/energy on someone else's stupidity. After all, we have to pity them since they are afflicted with such burdensome stupidity.

[cliffy21]

Never mind Ormand. He is on both forums i visit, and he does the same thing on both of them. I will make it easier to understand why he is a know-it-all: he is an engineer. He things that since he is an engineer, he is far smarter and more knowledgeable than anyone else on here, including the mechanics and techs. I apologize if anyone else on here is an engineer, and are not an a-hole, but in my experience most engineers are very smart, but have zero people skills. I'm glad that blowhard has a small vacation. Thanks for that.
