Question about torque on the 05 G35
How come on the 05 G35 you lose 10lb/ft of torque when u go with the manual?
The auto has 270 vs. the manual's 260, yet in hp auto: 280 and manual:298

There's another factor, too. The auto engine is tuned to be driven best by an automatic transmission. The manual engine is tuned to be driven best by a manual. This was just explained to me this week by a Nissan engineer. I will do my best to repeat what he told me:
Look at the torque numbers. The auto engine makes 270 pound-feet at a lower rpm; the manual makes only 260 at a higher rpm. With an auto trans, you want that powerful push of torque to be down low, and to have a broad powerband. That will make the car feel fastest (and be fastest when not held in gear to redline). But when you drive that same engine with a manual, you encounter a low redline and no peaky burst of power at high rpms. So it doesn't *feel* as fast as it could. It's not as fun to drive. When you take that car to the track, you won't wring every bit of power out of it.
So they retuned the 6MT's engine so it's peakier and has a higher redline. Thus, you can wind it out, it makes lots of power up top, it feels faster and more exciting to drive, and (I think - can't be sure) it will actually be faster when driven all out.
I think they did the right thing. They are not playing favorites. Every G35 owner will have the fastest-feeling car, be it auto or manual! I like their attitude.

I've been waiting for someone to post some dyno results of each stock '05 car to compare them with the '04 results to see where the true gains lie and if the 298hp is an inflated number or not...
The '04 manual I saw laid 237hp and 225tq (and it was indeed pretty darn flat). I'm really curious as to the torque curves of the auto and manual as well...

just like the honda cars
you sacrifice a little torque for more maximum HP at high end
that explains why SUVs tend to have a lower hp since they boost more torque at lower rpm
