Check out the dyno here:
http://motegi.vtec.net/articles/view...icle_id=719873
269hp at the HUB. The 5AT makes 207whp, or 227whp at the hub, so it's safe to say the 6MT is making around 250whp, which is pretty good.
Here are some quotes from the discussion boards there:
"Shawn (author of the article) told me that the sedan's 207hp at the wheels is more like 227hp at the hubs. My 6MT put down 269hp at the hubs. That's 40hp more, my friends, from the same 3.5 liter "268hp" V6 engine. Let me just say that I'm glad I checked off the "6MT" box when I bought the car."
"Yes. Again guys, I'll post some comparison plots tomorrow, but consider that Belize's car put down 15 hp more than the average 287 hp (old rating system) 350Z 6MT. It put down about 27 hp more than the average 6MT TL (270 hp old and 258 hp new). This car is making a legitimate 285+ hp at the crank - and it feels like it too. "

I'm thinking that if the 6MT dynos 269hp at the crank, it should probably hit around 228hp at the wheels (assuming a standard 15% tranny loss), but definitely nowhere near 250whp.
I saw an all black one just yesterday at King of Prussia mall and it looked great; it had very nice wheels on it, not sure what kind but not stock; it sounded great, too. I was favorably impressed and my boy did a 180 turnaround about his "dad what should be my first car" and me saying "honda" to which he vehemently disagreed until yesterday.
You are assuming that the factory rating is accurate. I don't know if it is or not, but this wouldn't be the first time that the factory rating was on the low side of what the average production car puts out.

Why does it seem that so many of the amazing HP numbers come from the same shop, i.e. the Dynapack dyno at Church's Automotive? Are they sure that thing is calibrated correctly? Maybe its just me.

That's why some people are suspecting that the accord 6MT V6 is actually making 280+hp at the crank.
It's the same situation with my AV6 6mt's 3.0 being rated at 240 HP at the crank and the CL-S6 3.2 being rated at 260 HP at the crank, but when both were put on dyno's, the 3.0 nearly put down the same WHP numbers as the CL-S.

But then keep in mind that some manufacturers would underrate their cars for marketing purpose, in this case, if Honda claimed the Accord to have more hp, then it will steal sales form the TL/TL-S (which is already happening). A great example would be the BMW 335i, BMW claimed ~300hp, 300lb/ft of torque, but according to one of our moderators, it has 275whp, but 300lb/ft of torque, and yes, at the wheels, not hub.

However, if he based the 269hp off Honda's spec sheet, then that's a different story. I guess the point is that his post was a bit vague in its description.
He did dyno at 269hp at the hub. And he also said that the 5AT model dynoed at 207whp (211 with premium 93 octane gas) at the wheels, but 227hp at the hub. In other words, there's a 20hp difference between measuring at the hub and the wheel. If you minus, say 22hp from 269, then it's roughly 247whp, which is about 250whp. Also note that the test was done using 87 octane gas as stated by the owner of the car.
"Yes. My car was tested with regular 87 gas. Like Jeff said, I accidentally put in 87 octane again after the dyno runs out of force of habit, lol. I'm so stupid. "
http://www.vtec.net/forums/one-messa...icle_id=719873
They will conduct another test with 91/93 octane gas (it takes a bit of time for the engine to "learn" that the octane is higher. For now, keep in mind that the last gen accord, with premium gas, it makes 10hp and 10lbft more.
Anyways, about the "at the hub" discussion, here is what the author of the post said,
"At the hubs. Look at the comparison plot links I posted. Most FWD cars lose about 25 hp from crank to hubs (manual tranny). If that holds true on the Accord, we're looking at around 290 hp at the crank - or about as much as the new TL-S
SC"

I'm eager to test drive the new AV6s. The V6 in the previous generation was quite powerful, I really liked it.

However, I do agree that the 08 Accord's engine will yield noticeably better numbers with 93 octane over 87.

Yea, I see what you mean, I guess the conclusion is that Honda underrated the Accord by a bit. From my understanding the rated hp number is at the flywheel, ie, for the accord, it should be 268hp at the flywheel, not at the hub. Since now it's making 268hp at the hub, it's safe to say it's making more at the flywheel. And the 20hp difference is between the wheel and hub, not the wheel and crank.
And here's what the author has to say about the dyno machine he's using:
"I was already talking with Honda engineers before we did the test. They told me to expect it to dyno high. There's nothing wrong with the dynos - we do 1000's of cars each year on them, including a lot of national championship and world record setting cars - thus we know the power levels are accurate.
Besides, you've seen the dyno plots from the TL and the G35. How do explain an Accord putting down the same power as a 298 hp Infiniti on the same dyno?????
SC"
Another added that it's possible the 5AT engine is tuned differently than the 6MT model. It's just that the marketing people purposely rated them the same as most people (95%+) would buy 5AT instead of 6MT. By rating them the same, the people who by 5AT would not feel they are "missing" something. He also said that he drove both 5AT model and 6MT model back to back and he admitted that there's a major difference in terms of power.
However, that's what he thinks, and so that may not be true. So in other words, the 5AT model is not underrated nor overrated according to the dyno result and 20% loss, but the 6MT model seems to be underrated.

The coupe looks great and I do agree that it looks better than the previous generation. However, the sedan IMO looks like shit. It looks worse than a new Hyundai. I hate how the lights pertrude outside of the body like that. 
I'm a little scared for the 09 TL now.

I can't wait! Honda made the winner!
