Infiniti G37 dyno results
The lastest weapon fired into the HP war....the G37; 287 hp @ 7300 rpm, 236 lb-ft @ 4400 rpm, versus 236 hp, 218 lb-ft, for the outgoing G35.

The G37's engine, however, blows that performance away. It's rated 37 horsepower higher, but the G37 we tested put 51 more horses [than the G35 coupe] 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.

hmm doesnt that suck so the g37 dynos @21 more hp at the wheels than we have at the crank and gets better gas mileage.... oh well.

FWIW: Lotus Elise 1984 lbs and 190 hp. Just over 10 lbs per hp!

being a g35 owner i really like what they've done to the g37, its an improvement in almost every way. please remember that its not a pure sports car to begin with.
but to be honest, if im in the market to get a car next year or the year after, id probably go with the even more impressive 335i twin turbo coupe, unless the G37 is dramatically cheaper, like at least 5k cheaper. even though it has 30 less hp, the bmw is so much cheaper to tune.
Id be interesting to see how they fare stock vs stock, i imagine itd be close, they are around the same weight, bmw has more torque while infiniti has more power.

Automobile Review
Neither provides very detailed numbers, but the comments made on how the cars stack up are pretty interesting.
