2008 Infiniti G37 Coupe

AND HERE'S THE DYNO RUN:
Dyno-tastic! Infiniti G37 on the rollers


http://www.autoblog.com/category/infiniti/
Infiniti hasn't announced its official peak power numbers for the 2008 G37 coupe, so the impatient folks at Automobile threw one on a chassis dyno to see how the power it puts down at the rear wheels compares to the 330 hp and 270 ft-lbs. of torque the Japanese automaker estimates the car will make. It turns out Infiniti wasn't exaggerating about how powerful the G37's new 3.7L VQ37VHR with infinitely variable valve timing is, and the new engine blows away the previous 3.5L motor in every way.

According to Automobile's dyno graphs, the new 3.7L produces 287 hp and 236 ft-lbs. of torque at the rear wheels, which means friction in the drivetrain accounts for about a 13% loss in power from the flywheel. The previous 3.5L VQ V6 used in the 2007 G35 coupe produces 236 hp and 218 ft-lbs. of torque at the wheels. This means that although the new engine is only 5.6 percent larger in displacement, it produces almost 22 percent more power than the engine it replaces. Automobile does note that it can't be sure if such a large increase in power is due to the new engine or reduced friction in the drivetrain, but suspects that since the drivetrains of the 2007 and 2008 model are similar that the gains are mostly from the motor.

That G37 is going to be mad fast but again...it looks plain a fck. Dull. I wouldnt put my Gs on it...unless it hits 12s stock, then I would reconsider lol.

That 08 altima NEEDS to be lowered and some good wheels and should look hot...but stock; it looks like its sitting on 24s...except it has 16s (17 i assume, but they look 16ish)
 
2008 Infiniti G37: On the Dyno - Charts

The 2008 Infiniti G37 Coupe is the first car to use Nissan's new 3.7-liter V-6. Infiniti still hasn't finalized peak output ratings, but estimates that the engine makes 330 horsepower and 270 lb-ft of torque.


The new VQ37VHR engine, as it's called, is the first V-6 sold in the USA to use infinitely variable valve timing in place of a throttle. This system, called VVEL, is the second such system on the market -- BMW's Valvetronic was the first.


We discussed the new engine in depth in previous articles on the G37 (see related links below) so let's cut right to the chase: The new 3.7-liter is only 5.6 percent larger than the old engine, but made almost 22 percent more power on a chassis dynamometer.


We tested the 2007 G35 Coupe 6MT on the same dyno a few months back. When attached to the six-speed manual transmission, its 3.5-liter is rated at 293 hp @ 6400 rpm and 258 lb-ft @ 4800 rpm. Its power peak is very close to the 6600-rpm fuel cutoff - this is an engine that loves to rev. Looking at the dyno chart, you can see that it comes alive just over 2000 rpm and produces a fairly constant amount of torque until just over 5000 rpm. Torque (and the corresponding push in your rear) drops off only slightly, as the engine is still producing over 85% of its peak torque at redline. Impressive indeed.

The G37's engine, however, blows that performance away. It's rated 37 horsepower higher, but the G37 we tested put 51 more horses to the rear wheels. Since this was measured on a chassis dyno, we can't know for sure how much of that increase is due to higher engine output versus lower driveline losses. However, since the drivelines are similar, we'd guess nearly all of this increase is brute force from the new motor. Think about it this way: If frictional losses are a constant percentage, you'd have to add 63 horsepower to the G35's engine to make it put 51 more to its wheels. This is a big, big jump in power.


The best news is that Infiniti wasn't exaggerating about its other claims: the new 3.7-liter is stronger than the 3.5 both at low revs and high revs. Its torque curve is flatter, too. Throttle response (if you can say that about a car without a throttle) is instantaneous, the 3.5's coarseness has been tamed, and I got an indicated 27 mpg - with the air conditioning switched on at 80 mph - on the way back from the dyno shop. So if there's any drawback to VVEL, we haven't seen it.

but does "no throttle" mean no throttle body? that's the part i don't get. if it's just a drive-by-wire tb then that's easy, they make it sound like there's no throttle body though which confuses me, like intake straight to IM straight to valves

Actually it means there is a throttle body but it is an electronic mechanism (ie. solenoids) that open and close it. The 06 WRX is a drive by wire throttle as well. Basically it means there isn't a cable/rod connected directly to the throttle body. This means that when you press the gas pedal, the distance you travel is translated through the computer to correspond to how open the throttle flap should be.

The reason I mentioned the 06 WRX, was because purists were concerned about the lack of response by not having the throttle mechanically connected to the pedal. Personally I didn't find it any different. Maybe it was just me?

but that's just drive by wire and lots of cars have that. they're describing something different

"is the first V-6 sold in the USA to use infinitely variable valve timing in place of a throttle."
 
i bought the g35 sedan and i love it!!! It an awesome car for the price!!! Its fast, has a lot of technological things and it has a lot of potential!!! Im pretty happy with my purchase LOL!! This g37 is going to be a beast!!

How many cars do you need?

Edit: I should of read closer!! What a dork I am!!

the only issue i have is that '07 Altima coupe w/ the v6 is gonna be around $30k+...why would anybody buy that over a G37? I'll spend the extra 4K and get the Infinity...

Don't know, maybe not everyone want a FR coupe.
 
Why can not people spell Infiniti correctly? Infinity is the audio company. Just ranting.
 
loller_boy mispelled it and he has one hehe. priceless.

im curious to see whats the 1/4 miles ET on this car...

I'm jealous :(... Which model did you get?
