AcuraTL085AT

When I look at the Car and Driver road test of the 2004 Acura TL, they got a 5.7 second time from 0 to 60.... http://www.caranddriver.com/reviews/...a_tl_road_test

Even the 2005 got a 5.9 second 0 to 60.... http://www.caranddriver.com/reviews/...omparison_test

What I want to know is why the 2008 Acura TL gets a 0 to 60 of 7.0 seconds to 60. At first I thought it was because the 2004 and 2005 had 270 hp while the 2008 has 258. But then I found out that they actually have the same exact engine, its just that they counted hp different back then.

So could someone explain to me why the 2004 acura TL was ridiculously fast and how the 2008 gets to 60 in 7 seconds?

P.S. And I heard turning off the VSA in my TL will make it faster, is this true? how much faster? Thanks alot guys! Love this site

Manual Transmission

^ That's because you saw the time for 5AT tranny on the '08 TL. The Auto tranny version is slow, hence you saw the 7.0 sec in 0-60 which is a bit conservative number. The better number on the 5AT is usually at 6.5 sec. 6.3 sec if you pray, and with brake-torque launching.

With a good driver the 6MT does it at 5.7 sec, even more importantly, it pulls like maniac at higher speeds. You will see larger gap(distance wise) at the quarter mile. It's all the gearing that makes difference. Lighter weight and less power loss on the drivetrain helps too.


This is why I have been hounding on ya guys don't group the 6MT TL in the AUTO TL as they are very different from each other. Different animal, different cars.

Its the same car and same engine! Numb nuts

Manual Transmission

^ it don't mean jack when the gearings are so different. The AUTO version is heavier too. The manual version always get the advantage in the power AND handling department.

btw, watch your language.

Oh AND braking department...

I agree with MT. I've driven the A/T 07/08 loaners from the dealers. I always wonder what everyone was talking about when they were talking about hesitation. Now I know. Taking off in a A/T from a stop sucks, even with the VSA off! The hesitation is definitely there. My car was alot more responsive when it was stock.

You said brake torque launching, what is this? And does turning off the VSA make a difference? And what if I used sport shift mode? Thanks alot

Manual Transmission

^ Yes sir. Turn the VSA off. For straight acceleration from a dig use AUTO setting as it can do better than you shift in Sport Shift as the delay time sucks. Brake-torque launch means you press a brake and gas at the same time and let go the brake. I suppose for the Automatic TL 2500 rpm might be an idea? You gotta experiment to find the sweet spot. If used right then you can have improved acceleration from a dig.

And here is my friend that did 1700 rpm brake-torque launch on his IS350.

doesn't brake torquing often retard the ECU or something?..
oh and what would a TL-S AUTO do 0-60?

Manual Transmission

TL-S Auto does about 5.9~ 6.0 sec in 0-60.

i think if you brake torque for a second that it wont retard the ecu or whatever that slows u down. If u brake torque for too long then it's not a good idea.

Doesn't brake-torqueing eff up the brakes and tranny?

I mean, if you press the gas and brake at the same time, that can't be good for that car, can it?

Someone should just get four TL's together, MT base, AT base, MT S, and AT S, and just race them in a straight line, forever answering this question.

Brake torquing is certainly bad for the tranny and should be employed sparingly at most.

I hate cars

Powerbraking doesn't hurt the trans or brakes when done right. All it does is create lots of heat. If you're at a redlight and see the crosslights turn yellow and you start brake torquing for the 2-3 seconds until yours goes green, you're not hurting a thing. As long as you don't sit there for 30 seconds with the gas and brakes to the floor it won't hurt a thing. In fact, you're not shocking the drivetrain as much because everything is pre-loaded. It's probably easier on motor mounts, axles, and transmissions than just stomping it to the floor from idle. Again, heat is the reason it's bad but if you don't give it enough time to heat up, you're not hurting anything.

As for the rest of the crap in this thread, it's just too deep to bother disputing. Manual>auto in the sub 400hp realm and then it's all about the auto. Really, .5 second is not that big of a deal in 14 second land. My TL is just a daily driver, nothing more and I wouldn't think of having a manual in a non-sports car.

^^^ On that note, might not be a bad idea to throw in a tranny cooler if you guys plan on brake torquing every now and then. In my experience, the TL isn't very good at brake torque launching anyway...either that or I just ca't get it right. I believe someone started a pretty good thread on key points to launching a 5AT, but someone came up with a technical explination to why the TL cant really launch for sh!t with B-torquing. good luck finding it though, since search engines aint worth a crap right now.

When you brake torque the TL automatically starts in second gear. No benefit there.

Put the car in sport shift and hold the brake and give it a little gas, the car will switch to second gear to prevent quick starts.

The Lex has some awesome instrumentation.

Come on now, gtech doesn't mean crap. That's the ricer's tool for people that are afraid to go to the track. We had 3 local guys with properly setup gtechs go to Famoso and never was the gtech close to the real time and it added about 5mph or more to the trap speed. That's as gay as posting a video of the speedo and tach trying to impress people rather than turning some real times. Just keep in mind it's not a fast car if you're able to take a video of yourself "launching".

but AT TL-S = paddle shifters and MT TL-S = no paddle shifters =P lol

Is this like a quantum physics calculation?

Manual Transmission

I just found you posted this... Wow.

Were you having a bad day or something?

It's the Vector FX-2 he was using. It's more accurate than other ones out there. When used on smooth road surface it gets as close as the ones done at the drag strip. He has gong to drag strips to verify not only his IS350 but also other cars he had done. It's only off by 0.1 sec or less according to his findings.

You don't have to take a jet engine powered vehicle to test the acceleration. It can be *any* car. dang..............

can someone please find the thread about why our tl's can't brake-torque for shit?

i noticed this too when i went to the track. I did what the dude with the Infiniti G35 did to this AT... I got slower times.. i ran fastest 14.9 with intake and exhaust. BUT i ran a 14.7 when i had intake.. weird...

Manual Transmission

^ 14.9 on a TL Auto with mod (intake and exhaust) is pretty damn good. They usually get above 15 sec.





Oh sorry for the late response. Yea. I like it too very much. One of the things I like so much is when I get in my car and stare at my gauge instruments and how they lit. So prettie.

GLowrdr

I think they used to count seconds different back then too. All of the scientists got together and decided that shit happens way too fast, and they had to slow it down.

I hate cars

Yes, I was having a very bad month; doing the biggest loser contest at work, lost 30lbs in 30 days and won but you can imagine what kind of mood 1,000 calories a day puts you in...

With that said, I stand by my statement.

Seriously, only on an import board do you get people showing video of the speedo or a g-tech or equivilent to impress people. I would be more interested in a race side by side with another fast car or at the dragstrip.
