Reason for 15HP difference between Maxima and Altima

Reason for 15HP difference between Maxima and Altima
A friend of mine that is a respected insider for the performance industry gave me some info on the power difference between the Altima and Maxima VQ35 outputs.
Apparently, there IS a real world difference between the 2 cars. This is due to different ECU programming and a less restrictive exhaust design for the Maxima.
I assume this will be confirmed as time goes on and dynos start to trickle in for both cars.
I trust him and he would know, so I would say that this is accurate info. But take it for what it's worth.
Also, if the Altima isn't threatening to the Maxima in the next year or 2 when the new Maxima comes out, the ECU could easily be reprogrammed and the Altima may gain a few MORE horses, not that it needed them.

So upgrade the exhaust and use a Maxima ecu and bam(!), 15hp?!
Tweaking ecus for the 2000+ Nissans has proven pretty hard so far, so unless JWT gets their *** of the chair, I wouldn't count on to much in that arena.

"Reason for 15HP difference between Maxima and Altima"
Marketing!! The 240hp Altima vs the 255hp Maxima is just like the C5 being rated at a higher hp than the F-Body. GM says it's the C5s better exhaust. BS!!! We all know the F-Body is putting out the same power. If Nissan rated the Altima at the same hp as the Max, hardly anyone in their right mind would buy the Max. The Altima has cleaner lines, slightly larger interior, IRS, and a lower price. Many say the Altima interior is cheap. I found it no cheaper than the Maxima. I think most people that take a sit in a Altima are sitting is the cloth models. Cloth always makes the interior feel lower scale.

false advertising???, its not wrong to market the Altima with less HP than it acutally has (it is wrong to market a car with a higher ratting than it actually has). Other cars have came underrated from the factory, like the LS1 Camaro/Fbird example.
I to doubt there is a HP different between the Altima/Max until I see it on a dyno, b/c I've driven both cars.

Re: Reason for 15HP difference between Maxima and Altima
Less restrictive Exhaust?? Funny, last I checked, the Altima had dual exhausts, yet the Maxima doesn't
The ECU I can beleive. Marketing probably had a major hand in that one.

Well, then you didn't check very hard. The Altima has dual tips, but is not a true dual exhaust.
And I was referring to the exhaust system, which includes everything behind the block, including exhaust manifold, cats, y-pipe, b-pipe, muffler, etc. There are a lot of parts to that equation.
Hey, like I said, take the info for what it's worth at face value.

I really doubt there is much difference in the Altima's exhaust vs the Maxima's. I'm pretty certain that both y-pipes all the way to the cat would be exactly the same. It would be stupid for Nissan to have developed a completely different and more restrictve Y-pipe for the Altima simply because of "hp wars" sake. In this day and age, automakers strive to trim production costs. Making two seperate Y-pipes would be very expensive from a production and emissions standpoint. From the cat on back is where the Altimas exhaust is probably a little different. More than likely the Altimas exhaust pipe goes the length of the car thru the middle and under the IRS until it splits into the a "Y" for the dual mufflers. The Maxima's exhaust on the other hand goes down the middle, turns to the passenger side of the car (before the gas tank), goes around the gas tank, up over the beam, and back down into a single muffler. Both the Maxima's and Altima's exhaust pipes make some pretty strong turns therefore I doubt either is better than the other (the Altima may have a straighter path). If you really believe a "varible capacity" muffler makes more power, I've got some stickers to sell you that give you 10hp.
What is so intriguing about the 3.5 VQ in both cars is the fact that they both have the same hp and tq peak ratings yet are rated at different hp and tq. I find that pretty much impossible. They both have the same compression ratio, variable timing, and variable intake. Visually they look identical straight down to the colored connectors. Does anyone else find it painfully obvious that the Altima 3.5 is indeed the same motor as the Maxima's. BTW, there's nothing wrong with underrating a motor. You're giving the consumer more for their money.

My bad. You're right. It looks kinda easy to make a true dual mod for the altima though.

Sorry to say Altima guys but the difference in HP rating is because the Maxima is using the exhaust system or many of the exhaust system parts from the Skyline GTR... It is in fact less restrictive.. I'm sure any of you who have modified the exhaust on your max, ypipe, muffler, etc., will agree there is a definite horsepower gain, not much mind you but some... That is the only difference between the two cars.. The torque ratings on the two cars are exactly the same, the only difference is the peak hp number.. To illustrate the Altima Auto 3.5SE ran something like 0-60 in 7.2/7.3.. The 2K2 Maxima auto, as well as Infiniti I35 ran 0-60, 6.8/6.9. So maybe there is something to the Max's less restrictive exhaust after all.. The weight can't account for that much difference, both cars are too close in weight...

I find it hard to ignore that the 3380 lb I35 ran .3 faster 0-60 mph then the 3361 lb Altima. The I35 ran .3 seconds faster in the 1/4 mile too. Also keep in mind both of these car's were tested on the same test avenue and likely the same driver. The stats from car and driver are below.
Infiniti I35 0-60 6.9 15.3@92 Car and driver
Nissan Altima 0-60 7.3 15.6 @ 91 Car and driver
I'm no rocket scientist but I can clearly see one is a bit slower then the other here, whether it is beause of a HP difference I don't know.
Once we get some real world dynoes in we can set this straight, once and for all.

Why wouldn't they be? Would Nissan develop two different 4 speed automatic transmissions for the same VQ3.5 engine? Doesn't sound cost effective.

Wait a minute. Given that the I35 and Altima and 2K2 Max have the same VQ3.5, the only difference being the ultimate HP, shouldn't we expect them all to have very similar accelereation numbers?? I mean, torque determines how fast you accelerate, and power determines top speed. Since they all have the same torque, the differences should only be due to weight and/or different tranny (LSD) only, which seems to be the case. The altima will have the lowest top speed. At 240 hp, that should be somehting like 145 mph. Hell, I could live with that low top speed

We also don't know if they were tested on the same day or track. Like you said, once we start getting some more numbers (dyno and track) then we'll see if Nissan is yanking our chain.

The Maxima has less torque rolloff than the Altima. As a result it makes sense the Maxima accelerates faster.

HP = (Torque x RPM)/5252
That's how the two are defined/related. Unless the two cars have the exact same HP curves they will not have the same torque curves. Since we don't have anything else to go on other than Nissan's numbers they will have to do. From these numbers at 5800 RPM the Altima has 14 ft-lb less of torque than the Maxima.
