What exactly was changed to bring about this difference of 10HP? Was it an ecu upgrade, exhaust, intake manifold??

What exactly changed? Thanks

Exhaust and it's not really 10hp to the wheels faster.

Here's the real breakdown on the engine differences (number wise)...

2002-2003 Maxima = 245hp/265tq
2004- up Maxima = 280hp/270tq

They overrated the '02-'03 models, and underrated the 2004+ models.

FameMax

Well lets have a look
2002 Altima =240ph
2003 Altima =245hp
2005 Altima =250hp

2002 Maxima= 255hp
2004 Maxima= 265hp

2003 Z= 287hp
2003 G35C= 280hp

Its interesting how 4 kinda similar cars can have the same engine with such different horsepower. I know the Z is different and im sure the 04 Max is, however I dont know how much I belive the Altima #s. My personal Opinion, VQ 3.5 in Altima and 02 Maxima has 245hp

Where did you get those numbers, facts?

FameMax

Me? where did i get those #s? Nissan?

I should search for the thread, but the explanation is the Altima 3.5SE and Maxima 02-03 have a "2nd gen" VQ engine bored or stroked (or both) to 3.5L with VTCs added, while the Z, G35 and 04+ Maxima all have "3rd gen" VQ engines in a 3.5L configuration. I guess the differences are engine differences which allow higher flow or higher RPM operation for the 3rd gens, thus giving them more HP?

(kinda like the 4th gen "1st gen VQ" vs. the 2000-2001 VQ30DE-K, which was the first incarnation of the "2nd gen VQ", at least in the Maxima)

Quicksilver: r u for reals about the the 04+ having 280??? isnt the same engine also if this is true. why is the 03 faster then the 04??? by a little or thats what i read??? correct me if im wrong
thanks

DrVolkl

From the 1/4 mile times I've seen, I'm not so sure the 04 is underrated at all. I also thought they were posting 211hp on the dyno...

The horsepower has to have been bumped up on the 6th gen because even though it has gained a considerable amount of weight, it can still hold its own agains other stock 5.5 gens. Please correct me if I am wrong though.

For the engine to have different hp ratings... wouldn't that mean different ECU tuning, different internals (or modified), and exhaust design and exhaust intake plus drive train, gear ratios, and whatever other factors there are? I'm lost and confuse...

injunk's dynos are always way off and always seems there intakes make 12-15whp which is BS.

If you don't understand why the 04 maxima should really be rated at around 275-280hp at the crank then check some track times(not magazines) and do a little research on car test. The 04's are running almost the same exact times as the 02-03's and they a quite a bit heavier. If you can't figure it out...give up.

MONTE 01&97 SE

iTrader: (1)

Remember the ones running 02/03 times are the 5spd auto SE not the 4spd auto SL, it is a tad slower than both. 04 doesnot have 280 hp and 270torque if it did it would be putting down slightly better times than I have seen. Has anyone proved this 1st gen 3.5 vs 2nd gen 3.5 or is it just speculation?

CCS2k1Max

iTrader: (2)

Granted they aren't perfect, but the bottom line is, the 04's drivetrain does not lose 20-25% of the crank power. Nissan's power numbers since 2002 are the result of marketing, not engineering.

F23A4

I TOTALLY agree. If the 2k4 had 280hp/270lb-ft, I'm willing to bet it would be putting down quicker times/faster traps than the 2k4 Acura TL and G35S 6MT.

we need a 6th gen guy to dyno his car. i dont know why no one has yet..

Quicksilver

iTrader: (1)

18" super heavy wheels + more curb weight and yet the 5 speed auto '04 SE still runs 14.6's...

The only explanation is that the engine is underrated. Some of us are pretty good at getting Cartest to simulate down to within .1-.2 seconds of real life cars, and in order for the '04 automatic SE to get 14.6's, it has to have 280 HP. The other key to remember is that you need to bias the extra weight from the wheels into the actual vehicle weight (since for some reason Cartest doesn't make much of a differennce on wheel size/weight and such). The extra weight on the corners should make the '04 Significantly slower than the 2002-2003 models, but in fact they run the same times.

i dont understand but i dont think they have 280 hp it doesnt make sense. let me see some dyno numbers.

Quicksilver

iTrader: (1)

Get the lazy bastards that own the 6th Gens to go dyno them. We all know that 02-03's have 240-245 HP, and in order for the 2004+'s to run the same times, they have to have more power than advertised. It's simple physics...

MannyNJ2k2max

If this dyno is correct....THERE IS NO WAY the 6th
Gen has 280 @ the crank....or 265 for that matter....

Blu

iTrader: (63)

if the 6th gen dynoed what injunk claimed there is no way Glude ran a 14.3@97 in his 6th gen stock. I'd also like to see an intake gain 11ft lbs torque

MannyNJ2k2max

iTrader: (3)

Glude 's timeslips show a date of year 2000....so leaves me skeptical.....so this is the only dyno we have....this is the only conclusion i can reach...

Now... its funny a computer be off for 3+ years on a track that has plenty of business....

irish44j

iTrader: (38)

but the ugliness of the 6th gen is sure to take off at least 20 hp at the wheels. that could explain it.

Blu

iTrader: (63)

It happens a lot believe it or not. I have slips dated from 2000 that were ran in 03 so I guess I'm BSin also. Look at injens dyno on a stock 6spd 02. 196whp and 200tq. If that isn't the biggest crock of crap I don't know what is. Look for yourself

MannyNJ2k2max

iTrader: (3)

oh...of course Injens chart is ridiculous....but i just dont believe it.....until i see an independent dyno showing at least ~ 225+whp stock.....then one can
assume the 6th gen is putting out 265-280hp

I believe these cars are capable of same times as 2k2-2k3's
but I still have't seen any solid proof.....
as far as ga2000....times of 14.6.....14.4....he has never posted a slip....ever....and its not even his cars its daddy's car.....and he posts 24/7 like its his daily driver...
[qoute -ga2000 ]"ok here it is, weather was 88 degrees and 70% humidity, this is no excuse at all car ran what it ran. this 1st of all this is my fathers car i dont drive it all the time."

Believe me....I want these cars to pull those times...I'm just a skeptic and i need hard evidence... some of these magazines would've pulled some numbers close to these by now......if it was the case

No sheet! Someone needs to dyno their '04. I mean, come on...$75 or so for 3 runs can easily be afforded by someone that actually wants to help out the .orgy...

we need more 6th gen

Hold up....this may seem like a hard core newbie question but what does whp (Horespower at the Wheels?)

Quicksilver

WHP is wheel horsepower

F23A4

I must have missed it also. (and still cant find it) Would you mind posting a link?

maximase86

iTrader: (24)

I have to agree with Quicksilver though. Based on the times the 6th gen putting out, it has to be putting out more than stated, or at least quite a bit more than what the 2k2, 2k3's are putting out. How can you get a car that is much heavier than the previous version to run almost identical times? 280hp at the crank is not out of the question at all. It's simple physics. However, though only way to prove this is with a dyno, which sucks cuz now what everyone is saying is just pure speculation and nothing more. And don't trust the Injen dyno's, they are just thier to sell a product, and most the people that dyno them probably won't dyno thier car's just to find out.

I think you guys are wasting your breath. We are 5th Generation guys. Who cares what those newbies are doing. 265hp or 500, who cares. It all comes down to the track times. If I was told that if Id give up 50hp from my Max, but it would be faster in the 1/4 or whatever, Id say you have a deal. My point is, the # of horses you got under the hood means nothing. The bragging rights come from the performance of the car. Lets help each other find ways to make our Max's quicker and faster, rather than argue over who has more hp. Am I right?

Quicksilver

iTrader: (1)

Not really...

DoGGy

man you guys are all WAAAAAAAY off.

the 6th gen max pumps out 750 hp. its got 6.5L v8 engine and it weights 2800 lbs. it also ran 10.8 seconds 1/4 mile and 3.5 sec 0-60.

now thats what i call FAST. good job nissan

feel free to correct me if im wrong

You forgot: its all wheel drive.


But seriously, maybe instead of the HP rating being at 280, maybe nissan is just catching up to its claimed horsepower (unlike the 5.5 gens which should be more like 245 at the crank). Just a thought.
