Bahhh here we go again..

Ok the sedan has diffrences. Do either of you have any mods? How did you launch? How did he launch? Any tire spin?

The Sedan has some diffrences: ECU, Cams, Exhaust, suspention, rims/tires, body/ride height.

The only advantage the sedan has is that it is lighter. I drove the sedan and it is a lot slower. The damn thing couldnt even chirp the tires.. Only on a turn. The power seems to be dead from idle to 3500k then it comes to life. Ill race a sedan any day.

The Sedan and the Coupe have the same motor just a TAD detuned.. Which makes the sedan much more mod friendly and after mods the sedan can be just as fast as the Coupe.

Hmm I chirp 1-2-3 on mine.

 

A wise old (street) racer once proved to a much younger (& ignorant) wannabe... that a weight reduction of about 7 lbs is equal to about one (real world - useable) horsepower at the rear wheels.. (he had a formula for figuring the torque as well, but I don't remember it). 'Point is... the same powertrains, in the same state of tune, in otherwise identical/similar vehicles, and let's further assume operators of similar skill levels... these vehicles, when raced, against each other or the clock, will always obey the laws of physics... the lighter one will overcome inertia first, accelerate quicker, and essentially get from point "A" to point "B" first - every time. Now, alter any of the mentioned variables and it'll surely impact the result, but it will still be within the laws of physics.

 

If it's 7lbs for roughly 1hp at the rear wheel... then the best aftermarket mod would be just to lose some weight...

make cents...>=)

 

I can't speak for the sedan drivers, but I will speak for myself, as a coupe owner. Every time I drive this car, it's like a special occasion. Even in a 25 degree weather, I roll my windows down, and enjoy the sweet exhaust note. I've had the car for about a year now, and I love it even more than ever before. A bunch of guys and I went out today, and everyone gathered next to my car, admiring it's looks. I got the car because I love the way it looks/handles/speed, but it sure is an eye candy. Nothing against the sedan, but I'd get the coupe, even if I had to do it all over again. Just my personal preference . To each his own...

Of course the coupe is heavier; besides the wheels/tires the coupe body with more steel/less glass and extra sound deadening, it is built to be stiffer. Here is some irrefutable math for those flapping gums over the huge advantage 100# gives the sedan:

Sedan: 3600 lbs/260hp = 13.8 lbs/hp
Coupe: 3700 lbs/280hp = 13.2 lbs/hp
The actual weights may be a bit off depending on driver, fuel load, etc, but the 100# difference is there. it doesn't make up for the extra 20hp. To obtain equal weight/power ratios the sedan would need 272hp....12 extra horsepower than it is listed to have.

Now 12 horsepower is likely outside the normal varience of bulk built motors.....that's less than 5%. But split the difference between both cars - 6hp more for the sedan and 6hp less for the coupe and that could explain the difference. Or, the sedan was about on empty and the the coupe had a full tank and a trunk full of tools. Perhaps the sedan had a better start. Who knows, but it isn't a surprise the two were close.

 

Now can we run those #s with the rwhp instead of listed crank?

Why is it that no one driving a (stock) coupe is man enough to post some dyno results?

My guess is that coupe owners quiver at the thought that they paid retail for a vehicle that produces the exact same horsepower as the sedan.

The whole 280 vs. 260 h.p. debate is as tired as a locked room containing three Catholic priests, Michael Jackson, and an altar boy.

It is merely a marketing ploy used to sucker ignoramuses into believing mythical data.

Although I think the coupe is a great vehicle in every way, I have serious doubts about the mental capacity of SOME of those who have purchased them.

OH NO HE DIDN'T!!!!!

 

"Why is it that no one driving a (stock) coupe is man enough to post some dyno results?

There are other reasons to get the coupe other than 280 vs 260 horsepower. And even then, there's no way every single coupe makes 280.

In a recent Socal dyno day, my car (5at coupe with z-tube, stock 18s) put down: 219.7@6200 HP (sad), but 228.4@4600 torque . Isn't it strange that with the car being rated for 280 HP/270 torque, that I have a higher torque figure.

Another 5at coupe with Z-tube and popcharger, stock 17s, put down 236 HP 232 torque, if I remember correctly. That is a strong car.

A 5at sedan with mods put down 214 HP, but there was difficulty getting the car to not downshift on the dyno. It kept wanting to go into 3rd. Interestingly, the 5at coupes did not have this problem.

On this very same dyno, I saw a 350z 6mt put down about 222 HP. Most of the 350z 6mts with mods were in the 240s.

So you see, there's a big variation between the cars, and it's really hard to say that all coupes have 280, all sedans have 260, and all 350z's have 287.

 

Oh yeah, and keep in mind if you're going to compare dyno results, the variations between dyno machines. The guy with the 350z who helped organize the event said that his car with the same mods was dynoing 10 HP more at the previous dyno at sealevel compared to the one from that day.

 

I'm certain that within a controlled environment, the 280 h.p. versus 260 h.p. myth would be instantly dispelled. Given a large enough sample group, the true r.w.h.p. numbers for all (stock) G's would be VERY close - putting an end to this so called "debate".

The entire basis of this thread accurately represents Infiniti's ingenious ploy of extremely successful marketing to a rather inept market segment.

Hence the random stupidity within.

 

Hmm. I don't think any of the coupe drivers were "tricked" into buying 280hp. We bought the coupe because it is what it is. The G35 coupe or the Skyline 350GT. If we wanted "more hp" why didn't we buy a STI or something... There is no "ploy".

For those who chose the coupe for its looks, that's great. My point still stands that Inifiniti marketing is the sole impetus behind the supposed variation in horsepower ratings of the coupe and sedan. I just find it appauling that individuals capable of affording this vehicle don't even have enough brain power to realize both cars have the same motor.

Both cars are great, I just think some of these a$$ clowns who purchased the coupe based on the unfounded belief that it is faster, or more powerful don't deserve to drive a G (coupe of sedan) at all.

 

That's the one point I'll stand behind in this thread-- those who seek soley to differentiate the two and deny any commonalities are the ones that don't deserve this car, whether they be a couper or sedanner. To say these cars are worlds apart is to show your true colors. It shows ignorance with intent, which is far worse than just being uneducated to the facts.

But that's just me...
