The new Accord V6 is DESIGNED to run on 87 octane. It is RECOMMENDED. Putting in premium most likely won't do anything (sometimes it hinders performance if your not using the proper fuel).
The Accord engine management is TUNED to run on 87 octane for optimal performance where the Altima's is NOT.
Ignition Key is the guys forum name on V6performance.net and also a member of VTEC.net. He was the guy that put down the 239WHP with premium fuel only in his 08 AV6 6MT! Thats around 280HP to the crank. Honda stated 268 and now 271 on unleaded. Its close to about 7-10 HP and maybe 5 WHP gain from premium.
Check out this dynopack. The new AV6 even put out more power on it then the owners 05 G35 Coupe 6MT.
Shows a great comparison against the TL-S they dyno'd.

You will notice in this dyno the CORRECTED and UNCORRECTED Factors that I was referring to in our earlier posts. Where Temp, Humidity, Elevation are all factored in!

lets get something straight , all gas , ALL GAS sold at gas stations is UNLEADED !!! there are 5 grades of gas which make up just about all gas sold at gas stations (octane) 87 , 89 , 91 , 93 , 94 the most common grades are 87 , 89 , 93 and in california 91 . 87 is considered regular and 91 (cali) 93-94 is considered premium .

u can find out how much you're making at the crank by taking that number and dividing by .86(14% loss) so yeah its 278, but he was on premium? Thats interesting. Once again however its their 5000 RPM torque peak that gives them the advantage, if we are making the same power it does not matter because everytime he shifts he hits his torque peak and I do not.

The highest octane we get in Hawaii at the pumps is 92 octane, sucks. I would love to have 93 or 94 octane.
Comparing 2 different cars times from 2 completely different tracks is not a good way to compare which car is trully faster, so much variables that you can't accurately compare them. Altitude, track prep, weather, etc. all change with every track. Best you can do is try to improve upon your own times and driving. Comparing dyno's is not an accurate way to see which car makes more power unless it is on the same exact dyno, and done back to back from one another. Comparing the HP and TQ ratings the manufacturer provides and then taking the vehicles weight and making HP/weight ratio calculations to see which car is faster don't work either. So much variables aren't factored in that make a huge difference. Even when looking at their HP/TQ charts, one could have more peak hp, and peak TQ but the other has a broader power curve with more power under the curve from xrpm - xrpm.
All that set aside, I think the latest gen Altima's and Accords are close enough to eachother in performance for them to be a drivers race. So practice up, get good at your launches, get good at powershifting, and you'll have the advantage over the regular joe schmo driver. We can all stop these pissing contests cause I'll bet if we all gathered for a race day, these little things wouldn't matter and the majority of us would get along great.

You don't know if the Accord I raced was running in terms of fuel. Another thing, you think 5 WHP is going to make that much of a difference??
Even lets say I got with my 242 WHP uncorrected, its still higher then 239 WHP (Highest dynoing Accord on the web).
Not to mention my car weighs less. How do you expect it to pull on me??
My car puts down more power than a 05 G35 Coupe 6mt so what? You don't realize how unTUNED these VQ35's are. My A/F ratio was running in the low 11's and when it got to 5500 RPM, my A/F ratio was around 10.5:1 (Thats worse than my Talon which is at 11.5:1).
I beat TWO Accord V6's, same outcome. One of them I know (I am going to tell him put premium fuel and lets do a re-run this week). The other one was some dude I ran into.
I contacted my dyno guy to make sure if mine was corrected or not. He said no it wasn't corrected.
You lose 1% for every 330 feet above sealevel. I am sitting at 1200 feet which makes it 3.5%. Now 242WHP +3.5% = 250.47 WHP.
I didn't just BARELY walked on those Accords, I beat them with a okay pull.
Only V6 that I didn't beat was the G37, so far every V6 I encountered I have beaten.
I haven't raced the older 02+ M3's that makes 333 BHP. I wonder how I would do lol.
I know I would lose because they put down like 270-275 WHP.

You are a fool. Who didn't know that. I can tell it really bothers you when I say UNLEADED. When I refer to gas as UNLEADED it is the same thing as regular unleaded or I would have called it PREMIUM UNLEADED!
The highest octane we have here in AZ is 91 for premium or 100 octane Sonoco Racing fuel at 6.05 a gallon.

Yeah he said he had put premium fuel in since the car was new. You know what though......I looked at both dynos I posted and both of those 6MT make peak torque way before 5000rpm. The dynapack dyno shows 4414 peak torque and Ignition keys dyno peaks even earlier. Honda states 5000rpm but it looks like they were wrong according to the two dynons.

No I don't know what fuel the accords you ran were running and neither do you. I doubt they use premium since the manufaturer doesn't recommend it.
Its great you put down 242WHP. Its also great you beat both accords. But Dexion didn't with the same car you have. Thats why its a drivers race.

lol I don't care if your car puts out more power than the G35. I thought it was pretty cool that a Accord with a underrated 268HP an 248TQ to the crank ended up puting down more WHP and WTQ at a earlier RPM than the VQ35 in the 05 G35 6MT that was supposed to put out 298HP and now has been downgraded to 286HP. It makes it even better since Honda uses a SOHC setup and Nissan is Using DOHC.

The G has more drivetrain loss then a FWD vehicle. So the motor could be putting down more power, but when it gets to the wheels, theres too many things it has to go through.
I don't think you should be running your mouth about how the Accord has a SOHC and it puts down more power then a 3 year old vehicle.
The Accord's engine, like most Honda motors, is very well tuned from the factory. Where the VQ is pretty bad when it comes to well tuned. Running A/F ratios that would make a turbo car run rich is pretty bad if you ask me.
Why don't you compare the 2008 Accord V6 with the 2008 Infiniti G35?
Hell, why don't compare the MOST tuned 3.5L engine from Honda, the TL-S version that has a higher compression ratio then the Accords.
The G puts more power down and theres STILL a ton of room for tuning.
In the earlier years, you know that Nissan always OVER-rated their engines and nowadays, they can't do that anymore.
and HondaV6, your the fool for saying UNLEADED gas. Both premium and regular is unleaded so your not be very specific.
When it comes to the Auto's, the 2003 Accord V6 is faster then the 2008 Accord V6. My old boss has a 2003 Accord V6 5AT with an AEM CAi and raced his little brothers 2008 Accord V6 5AT. The 2003 pulled ahead everytime (Not by a lot though, he was walking him).
Then my old boss wanted to race my car and was claiming he would have smoked me. Anyway, we did a few runs and he got destroyed everytime. I would instantly start to put car lengths on him when we went from a roll.
I respect Honda's vehicles. They have great frames and well tuned overall vehicles, however, most of the owners are cocky bastards which isn't really fair to bash the vehicle.
I just need a good tune (12.5:1 A/F ratio) and I am sure the car would make another 12-15WHP easy.
3. I can tell it really bothers you when I say UNLEADED.
4. When I refer to gas as UNLEADED it is the same thing as regular unleaded or I would have called it PREMIUM UNLEADED!
1. a fool is a person that says unleaded gas and does not state what octane . if 87 and 91 are both unleaded , by you saying "unleaded" doesn't explain which gas your talking about .
2. you didn't , other wise you would have used the correct terminology .
3. it kills the conversation when you say "unleaded" to make a point , because then i have to guess what you were trying to say .
4. if you don't see the stupidity in that statement , i'm sending the "little bus" to come and pick you up !!!
again , if you have 2 grades of gas , regular unleaded and premium unleaded , both grades begin with the name unleaded , so the only thing that makes the 2 descriptions different is regular and premium , use proper terminology so you don't sound like an idiot .
p.s. all gas is unleaded , there is no need to use the word unleaded anymore , its an old term that doesn't apply any longer
