It appears that this car has a good amount of extra grunt up top. I checked out my last dyno plot and I make more peak TQ then the G35 at 3000 RPM

 

Is the 6spd G35 out yet? I'm assuming this guy was automatic... 213 to the wheels from a 260hp manual tranny car is weak. Please tell me he's auto.

 

Its an auto you can tell by the rpm range.

 

plus your car looks better

 

Whats that drop at 5250RPM about?

 

The G35 is auto only until sometime in late fall or winter.
If you think that tranny loss is bad you must think the auto maxima's dynoes are horrible! 213 from a RWD auto equipped car rated a 260 HP is pretty good IMO, especialy with the nissan over rated #'s these days.

Thanks Kashoggio

 

Thats the TQ dropping, thats prefectly normal, the maxima has a even steeper drop.

 

of course..

Now if only you were RWD.....

 

After seeing that it seems the G isn't the extreme high rpm breather we all thought it was. Admitedly, it holds on better but just seems to level out up top and not climb any.

 

its an auto

 

Maxima's with 255hp, 6spd and FWD are dynoing at 205hp and the Infiniti is dynoing with a whopping 8 more HP, with an automatic, and power robbing RWD. Impressive.

i always thought FWD was the power-robber.

you know something's wrong when a 260 HP auto dynos 10 more HP to the wheels than a "255 HP" manual.


its also strange that the dyno started at 4000 RPMs. i hit my peak torque at 3500 RPMs. i wonder if the dyno missed something by starting so high.

 

The only thing wrong with that picture is that Nissan has over stated the facts. The Maxima does not make 255hp. And according to that graph, the G35 is slightly below it's rated 260. The dyno didn't miss anything really. The G35 has a different intake manifold and doesn't make the same low end torque that the Maxima does.

 

exactly. hence "255 HP" in quotes.

 

Damn, it sure looks like the G35 has a VI. The upswing in HP@5200 and the way TQ holds on sure looks like some manifold trickery.

The reason the dyno starts so high is because many autos will downshift if you go WOT. Starting higher in the RPMs lessens the chance of a downshift. Of course, I thought you could hold the gears on the G35.

210+rwhp from a stock auto RWD V6 with less than 3000 miles is pretty impressive. I beat this car would dyno 220+hp after 10000 miles or so. The auto is only loosing about 18% thru the drivetrain. I'll take a G35 anyday. Even in auto form.

That is pretty weird especialy because the TQ band stays so smooth. It alsmost looks like the dyno messed up or something.

 

There's always the possibility the dyno is off. Until another Maxima is tested on the same dyno immediately after the G35 we may not no why there is a discrepancy. Nissan could have under rated the HP of the G35 and/or overated the Maxima. I remember in SCC magazine they were dynoing stock WRX's at 142hp and the next issue they apologized and said the dyno was off. The new figures were around 161 I believe.

Jesse

 

Remember, the G35 (and 2002 Max, for that matter) has variable cam timing. You may well be seeing the cam indexing at 5200 rpm. Although Nissan uses the term "continuously", the system may actually index via multiple discrete steps, and is not truely continous...something along the lines of 5 degree retard steps. Just a guess.

 

161whp is REALLY pitiful for a 227 hp car.

Stock 4th gen 5-speeds typically dyno about that

 

My stock VE dynoed 162

 

That is a very nice hp curve. Just enough to keep the shifts in the meat of the powerband under WOT. I haven't driven the G35 yet so I don't know how well the tranny shifts. If it shifts like an auto max, then some vb work and that thing will be sweet.

I agree with Dave B about the hp. 213/260 = about an 18% driveline loss. That's very good for an auto.

Now the interesting thing is . . . with 18% driveline loss, the 6 speed may not be much faster. That's just a hair better than the 15 or so on my 5speed.

This may be like the corvette - 6 speed only marginally faster.

 

Remember, AWD cars dyno lower because its pushing power through all four wheels. Its really misleading.

 

We need to find a G35 to dyno at the same time with a 2K2.

Anyone with a 2K2 got a friend with a G35?

 

227 is the 5th gen Max, not the G35.

FWD

 

Looks to me like they're talking about 161 out of 227hp being pitiful for the AWD Subaru WRX.

 

You are correct, for some reason my eyes saw AWD, and my brain said RWD....

 

Happens to me too.

 

There has got to be something wrong with that dyno plot. I have never seen in my life a tourque curve that stays that flat, minus the dip. The only car ever to come close was a viper. And that even dropped off at about 4,800. But hey maybe nissan has figured out something. Props if they did.

I think you are confusing the torque and hp plots like I did when I first saw it. Remember they intersect in the 5K rpms. The hp plot stays flat til redline, the torque drops off.

 

you wanna see a flat torque line then look at one from a stock 4th gen Maxima

 

Plus there are two differentials its going thrgh so it makes sense to see it lower.

 

so explain this to me. If the car has 216 tq. Why does the graph not show that. They have the same numbers on the left and right side of the screen for the scale, but yet the tourque number doesn't even come close to 216. More like 200. Just wondering!?

Which graph are you refering to?

 

There seems to be only one graph at the beginning of this post.

 

That graph clearly reads and shows 216 to me.

 

ok now i just looked at it again so see if im truly nuts here. One of those data lines......either tourque or hp, is just at 200. So one of them is wrong. I don't understand how you cannot see this.

 

The torque line starts at the top left and falls down to the botton right.

The hp line starts at the bottom left and climbs to the top right.

HP and torque lines always cross at 5252 rpms

So remember that on a dyno chart that torque will always be the higher number before 5252 and HP will always be the higher number after 5252. Torque is really what gets measured. Hp is merely a calculation of torque and rpm.
