Got my 07 3.5se 6mt dynoed

[07wHiTE 3.5SE 6sPD]

Dynoed today on a dynojet..... injen intake, stillen exhaust..... first run 239 whp in 3rd gear run.....second run 237 whp in 4th.......third run 241 whp in 4th again...... thats uncorrected.... corrected power is 247 whp...... this sounds about normal? thanks for your input.

[GreyZone]

Hmmm. I'm curious how that would compare to WHP runs totally stock....without that comparrision it's hard to gauge the results...does anyone have WHP numbers on this motor stock?

Using a somewhat standard 15 to 20% reduction for WHP stock would run from 216 to 230 whp, but thats so "ballpark" its really not too accurate in trying to understand what your true gains are...but your numbers sound about right and would indicate to-be-expected gains.

And what's the rational for "corrected" ?

thats week someone with a sedan with only a fujita intake got 261 WHPhttp://www.youtube.com/watch?v=hsL7j0l4NRs

I think the calabration on that machine was off...those numbers are not realistic. That would show over 300 HP at the flywheel, and theres no way an intake is gonna do that.

Even if the numbers Shawn got were abnormal, a while ago he had another dyno run and got 245whp with just the intake, which sounds about normal. (his stock was 233whp) So I guess stillen exhaust adds 2whp.

/scratches stillen intake off mod-list.

Those numbers sound about right. You have to take into consideration the power loss through the drivetrain which typically runs about 15-20%.

Just using an average run of 239WHP would give you:275HP @15% loss286HP @20% loss

I don't know, maybe I'm wrong. But, the numbers seem about right. Everything looks fine and dandy to me!

[Plastics]

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...

Yes, 291 is unrealistic. You're running a bone stock Altima 3.5, right? This guy has an INJEN intake and STILLEN exhaust.

A good intake such as the INJEN will typically give you anywhere between 5-8 HP while the STILLEN exhaust will bump you up anywhere from maybe 8-12 HP. That's just how it is. You're letting you're motor breathe better, thus creating more power.

The Altima comes from the factory rated at 270HP. Rather than sitting here going back and forth, why not just post your dyno chart? You said you had your car dyno'd at 291HP. You didn't mention that the 291 was at the crank. Dyno's spit out numbers at the wheels, so I'm assuming the 291 is the number your chart said. Normally people will give a WHP if asked how much power they put up on the chart.

Please, just post up your runs and if you're right that your Altima is that much more powerful than all of ours, and the ones coming from the factory, I'll be the first to admit that I was wrong. It's that simple!

[Dexion]

Intake should give at least 12whp, please stop saying 5-8 we already have dyno evidence from shawn's car that proves this wrong.

[generic808]

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.

[AZhitman]

We've already established that the intake claims were bogus as hell. Someone pull up the thread and link it, no sense in beating a dead horse.

Those are awesome numbers - G35 drivers, take note, and don't mess with an Alty Coupe.

[Dexion]

Here's the link for all you non-believers. Soooo the evidence is here whats the next comeback?

(before)233.14 (after)245.57ok lets see multiply the 4 carry the 3........... that gives me 12.43whphttp://www.youtube.com/watch?v=OBc5nyHR0AU

[generic808]

AZhitman, now tell me these guys aren't clowns. I'm not one to flame over a forum; never have until now. I just think some of these dudes "read" something online and then somehow take that info and run with it. All of a sudden, these guys have a "magical" Altima which somehow got away from the manufacturer and is suddenly 21HP more powerful than every other Altima ever made!! Pretty soon they'll be saying they dynoed 400HP off of a I/H/E combo with a bug shield and dash cover. I give up! These guys can think/say whatever they want. I just hope others aren't misinfomred by their info, or lack thereof, shall I say.

BTW people, read the thread labeld: HORSEPOWER JUNKIES IN HERE

[generic808]

Dexion, you can't even post a link! And you're all of a sudden a Master Tech who has a 400HP Altima?

[Dexion]

crap forgot to post the link!

[generic808]

Uhh...that's a dyno readout from the manufacturer...DURR!!! Of course the claims are inflated. I feel sorry for you that you actually believe that And by the way, that's the 2.5 motor. If you know what a motor is.

Now your ignorance is starting to show, listen to the goddamn engine, does that really sound like a whiney I4 to you?

Its already common knowledge that the 07 3.5 motor has a very restrictive stock intake design of course adding an aftermarket one will free up quite a bit of hp.

[generic808]

Here Dexion, you can supercharge your Altima for $39.99 plus shipping. It'll give you a 25% increase in HP: http://cgi.ebay.com/ebaymotors...ZWDVW

And what good is a SC without a chip? This one will give you 43HP: http://cgi.ebay.com/ebaymotors...wItem

Cool I'll look into it after I put on my 12whp intake.

That guy sells a lot of those "superchargers", and wtf? He has such good feedback, something isn't adding up right here....

[generic808]

I'm happy with my INJEN which probably gives me maybe 5-8HP. I'd take that anyday over a "imaginary" 12WHP which you claim. So you're saying that the intallation of a Fujita intake on a VQ35DE will give you about 14hp at the crank? ok, if you say so When you do install the intake, please dyno for all of us. That'll be the end all.

[audtatious]

You mean THIS thread

zerothread?id=271988

[generic808]

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...

[audtatious]

Let it go. Not worth the arguement at this point

From the Maxima camp, we had people making the same claims saying the factory intake was super-restrictive and such. When it came time to test long-ram and short-ram intakes, the dyno results showed no real improvements across the board. Sure, some would show 5-10hp here and there, but _anything_ can pretty much cause +/- between dyno passes. Now, with headers there were some additions, but that was kinda expected.

[Dexion]

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.

Don't forget the debadging...

[coreansurfer]

it's an altima why even bother?

Butt-dyno can be deceiving. You know you have a new part and you hear it being louder at WOT which will make it seem much faster. Realize we are not saying aftermarket intakes do absolutely nothing, just that the dyno numbers provided are not what you should expect on the street.

Here's an interesting link I ran across a while back: http://www.turbomagazine.com/t....html

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

Door swings both ways
