^ I think most likely it's because he didn't let the car cool down first for the reason given above.

How long was the car supposed to sit before it cooled down?

Well, I guess I can bring this up here. I just came back from the track and witnessed a 5AT 07-08 TL-S make a couple of runs both 14.9 seconds 93-94mph each run. Between the times I have witnessed for 2G and 3G TLs as well as my own 07 AV6, I am convinced that the AT in each seriously saps the performance of the J series.

Sidenote: My son also ran his 05 Altima 3.5SE 5MT tonight for the first time and posted a best time of 14.4 sec @ 96mph.

05 altima 3.5 has 6mt... typo im assuming just saying for those who might not know

what kind of av6 you have? sedan? coupe? AT? MT? curious as to how it runs in comparison to a 5.5 gen maxi or 2nd gen tl-s in terms of performance... i was thinkin of trading up for one recently but decided on no car payments and i thought i remembered reading you previously owned a 5.5 gen maxi.

That's interesting as Jeff at TOV managed 0-60 in 6.3 seconds and the 1/4 mile in 14.5 seconds@96-97mph in a 2004 TL 5AT. It's as fast as the 7th gen AV6 6MT sedan he tested. I guess he really knows how to drive a 5AT TL.

well Bearcat94 did 14.3 w/ his 5AT TLS; so depends a lot on driver

According to Dave B though that was a fast track. But yea, depends a lot on the driver and conditions. I think 14.5 in a TL-S is highly attainable considering even a normal TL 5AT can get 14.5.

I have an 07 sedan 5AT. Off the line my old 5.5G will obliterate it but, on the highway I think my AV6 can hold its own against the Max.

F23A4

Having spent some time driving the TL 5AT, I doubt it would hit 14.5 sec ETs with any consistency and without mods. Honestly, it seems to be as quick/fast as my AV6...and that aint hittin' mid-14s on a downhill track. But, I do believe that the TL-S 5AT s/b capable of posting a 14.5 second ET.

Yea, that's what I thought too, cause no way a 04 TL 5AT would be 0.3s quicker than the 2nd gen TL-S. But this is what Jeff said,

"
based upon our instrumented testing, the Accord 6MT sedan ran 0-60 in 6.3 seconds. With no limited slip the car was struggling mightily with the 60ft times The Accord V6 5AT is a bit behind at 7.0 seconds - it launches pretty softly. The '04 TL 6MT we tested ran 0-60 in 5.8 seconds and the 1/4 mile in 14.2@98mph. The '04 TL 5AT ran 0-60 in 6.3 seconds and the 1/4 mile in 14.5 seconds@96-97mph. The '05 RSX Type S was good for a 0-60 of 6.1 seconds. We haven't tested a TL Type S 6MT against a clock yet but I've driven both the 6MT and 5AT '07 TL-S and once you get it out of the hole I can assure you that the TL-S will stomp an Accord 5AT or 6MT. On the roll the Accord V6 vs a 3.2TL is pretty close."

http://www.vtec.net/forums/one-messa...page_number=2&

I guess may be there instruments aren't that great? But the times for TL 6MT, RSX-S, are right on so that shouldn't be a reason. Also, he said the the 5AT AV6 is pretty slow (0-60 in 7s), which is definitely in line with what you saying, "it launches very softly," in other words, the Maxima would smoke it. I guess may be he got lucky with that 14.5s run with the 5AT TL.

I think you're looking too deeply and picking things apart too much, honestly. I certainly believe that a 3rd gen TL5AT could run a 14.5 bone stock, but it would be an anomaly, just like TypeS09 running a 13.9 in his 6MT with just an intake. Granted, today's cars have production tolerances with much less variation than the cars of yesteryear, but small variations are likely still possible, thus creating a "semi-ringer". This isn't even taking into account weather conditions, which will play an even larger role in acceleration deviations.

hahaha I just want to know what these cars are capable of, and I simply enjoy researching on them....or may be I just have too much time on hand....:P And yea there are too many factors...like my other post, wind speed alone will give or rob a lot of power.

wow... really?? i assumed b/c of the 02-06 3.5 maxi's coming with a 6mt i guess... well you know what happens when you assume...

i stand corrected

SatinSilverAV6

iTrader: (2)

The instrument testing is off for all the cars. Peoples times are all over the place in reality. Its atleast going to give us a close idea within a half second or so.

SatinSilverAV6

iTrader: (2)

The 5AT AV6 seems to average about 7seconds flat. The times range from about 6.5-7.5. I have seen 1/4 mile times all over the place from 14.8 stock to 16.3 stock. It seems to me that the 03-05's are quicker than the 06-07's based on 1/4 mile times that I have seen. I know track cond. and elevation play a key roll.

F23A4

No problem, as you made a VERY logical assumption. As a matter of fact, I think the Altima 3.5SE is the only VQ35DE available with a 5MT. All others (Maxima, Alti SE-R, G35 and Z) are 6MT.

F23A4

I kept bogging down at launch when I did run my AV6. I really believe that if it were not for that, I probably could hit low 15s and maybe upper 14s.

SatinSilverAV6

iTrader: (2)

You should go back to the track with your son. I know you would be able to improve your time!

iforyou

iTrader: (1)

Yea, at the of the day, there are just way to many factors to consider. Really? the 03-05's are a bit faster? I would've thought the 06-07 should be a little bit faster with a few more hp.

Does the Altima really need an extra cog though? With that much torque down low and in the midrange, I would imagine that should be enough. The Accord on the other hand, or any J30 and J32 would need some more low end grunt, otherwise bogging down would happen a lot.

Ah, I just noticed you (satinsilverav6) has a...AV6 (how did I miss that..it's your name..), what times did you get, and I'd assume it's 6MT?

FiveLiterCheater

My friend with an 03 5AT coupe ran 14.9 with just a AEM V2.

Soseductivesf

No he has an auto.. I think that was a wasted dyno and I should have let it cool down.. also the first 2-3 runs were unrecorded(problems with the dyno) so they kept running it over and over

SatinSilverAV6

iTrader: (2)

So far the 1/4 mile times I have seen the 03-05's seem to be a bit faster. The 06-07's weigh slightly more and only have 4 more hp and actually lost 1tq.

I have a auto. I have only ran at the track here in Tucson. SIR sits at 3075ft and its not the best track for great times but its not bad. I ran a 15.5 stock @91MPH and now I am down to 15.2's@93MPH. So at sea level I would probobly be in the mid 14's. I did take out a 04 Maxi 5AT SE here that was stock!

iforyou

iTrader: (1)

I think the 06-07 were tested using the newer SAE Standards, smiliar to the TL, 270hp vs 258hp deal. I'd imagine the changes would be more if it was tested under the old system...I don't know..just guessing..

SatinSilverAV6

iTrader: (2)

After seeing the dyno's there isn't any noticable difference between them. I think that Honda just raised the HP to 244 just because the engine was already making that to the crank. The 03-07 AV6 stock autos were putting down more WHP than the stock 3rd gen altima 4AT and stock 5.5 gen maxi autos. I believe the 240 rating is correct even with the new SAE standards.

iforyou

iTrader: (1)

ahh, thanks for the info. That's pretty amazing considering it's only a 3L engine. Do you have any dynos that I can see?

F23A4

That is part of the equation but their were a couple of improvements to the intake and exhaust systems between the 7G and 7.5G models which lend itself to the power increase. As with the TL, a straight SAE NET application to the 03-05 AV6 probably would have resulted in a lower reported hp/lb-ft for 2006.

iforyou

iTrader: (1)

Yea, something like 230hp?

SatinSilverAV6

iTrader: (2)

I don't believe that the 03-05's would have had a lower HP and TQ in the new SAE standards. Stock 6spds are putting down close to 220whp and the autos close to 192-196WHP. After seeing what these cars dyno stock the 240HP rating and 212TQ rating are right on. Check out all of the dynos on V6 performance . net

SatinSilverAV6

iTrader: (2)

These dynos were taken from VTEC.net and stevetec put the TL and the Accord together.

http://home.comcast.net/~stevtecv6/d...ompare_med.gif

F23A4

That is my hunch.


When Honda went to the updated SAE-Net standard EVERY pre-existing J-series was downrated with the exception of the Accord V6 (which underwent an intake/exhaust upgrade from the 05 to the 06 model years): TL (270hp>258hp), RL (300hp>290hp), Pilot (255hp>244hp), Odyssey (255hp>244hp), MDX (265hp>253hp) and AV6H (255hp>253hp).

SatinSilverAV6

iTrader: (2)

I don't disagree that every other pre-existing J-series was overrated however that doesn't mean that the J30A4 would be part of that overrated figure just because its a j-series. The dynos prove that the J30A4 was making the 240+HP figure. Even the 02-03 TL-S which we know didn't make 260HP(probobly 240-245HP) to the crank put down about the same WHP as the 03-05 AV6 auto does. Also the 255HP 5.5 gen maxima 4AT and 240HP altima 4AT put down less WHP than a 03-05 AV6. My buddy that did dyno his stock 4AT Altima put down 190WHP and 210TQ. I think you know as well that the Maxi wasn't at 255 but more like 240hp like the altima. The 03-05 accords are definantly making more than the 230hp because the 6spds wouldn't be putting down 215-220WHP stock and the autos range between 192WHP-196WHP stock. I also haven't seen a dyno for a 06-07 accord that supports that 14hp (10WHP gain) over the 03-05's. The 4HP seems accurate for minor Intake and exhaust revisions. Its definantly not free flowing like my I/E setup is.

F23A4

As evidenced by the AV6H (whose power reduction was a mere 2hp), it is possible that the J30A4-J30A5 "SAE-loss" could have been just as negligible.

As for the A33/FFL VQ35DEs, it is true that the HP numbers were overrated but then again, the lb-ft number were grossly underrated. So that is a wash (of sorts).

SatinSilverAV6

iTrader: (2)

I definantly agree with the grossly underrated tq numbers for the VQ35DE. My buddy put down 210TQ in his stock 2002 4AT Altima 3.5L.

F23A4

UPDATE: MY son just called from Etown and said he just posted a 14.3 @ 97mph. I will post the full numbers when he gets home.

SatinSilverAV6

F23A4

Yup, all stock with 75k miles on the odo. On a slightly slower run, he posted a 98.8Xmph trap.

Those Altimas move out pretty well with the manual. What's his launch technique? What does he have for tires?

iforyou

iTrader: (1)

Is it true that the new Altima's with CVT are really that slow? I've seen numerous videos that the 0-100mph is even slower than a 2nd gen Type S. I thought Nissan claims that CVT is better because it can keep the engine running at the most optimum speed and shifting is not required thus faster.....
