Acura TL SH-AWD 2009 Auto and DRAG

Anyone tried drag with his TL ? I cant find any way to start fast with this car ... i tried every mode and combination possible and its always slow to start ...

Any tips ?

I also use tablet with torque software to see stats etc and i cant get more than 165 hp and 220 of torque whatever i do ... also when i try the manual mode and go its goes from M1 to M2 directly within 1.5 seconds and come back to M1 to rev until 6200 rpm and go to m2 after ...

Dunno whats wrong ...

Thanks for your help

TL's are a very HEAVY car with a long stroke engine. Drag racing is not something is going to do well.

I was doing 0-60 in 8.7 ... on internet in several sites they get 5.2 5.4 ... there is a way to get better than 8.7

I have a 2010 Sh and in Manual mode using the paddles the car will hold RPM until it hits the rev limiter or to the point you shift. This should be true for all 2009 to 2011.

In 2012 when they changed to the 6 speed Auto,it would auto shift from 1 to 2, and would not hold 1st to redline.

8.7 sounds really high and 5.2 /5.4 may only be possible with a Manual gearbox. Keep in mind our cars are heavy and the AWD has a lot of drivetrain loss.

I found this video and it does exactly whats im talking about

https://www.youtube.com/watch?v=uGuLxGBmOTc

At start it pass from M1 to M2 to M1 and we loose seconds and we are not launch as if we start at 2000 rpm or more to get our max torque at start so its really slow to start ... dunno how they can do 0-60

Even on somes sites that review the car they get 6.7 seconds in 0-60

Edmunds
https://www.edmunds.com/acura/tl/200...est-specs.html

Car and driver get 6 seconds flat
2009 Acura TL SH-AWD - Road Test - Car Reviews - Car and Driver

Its really far away from what i get ...

Yes, I have seen that video. Not sure how that happens but I know for a fact that it does not happen on my car. Flooring the car from a standstill seems to produce a slight hesitation, I feel that easing the accelerator and then full throttle produces best results.

As mentioned above, 8.7 is high. Maybe some with a stock car can chime in and post their time for you to compare.

Most posted magazine times are hard to replicate in real world driving conditions.

Also, I would not launch an auto.

Not sure if you saw this thread about the HP/ TQ, will post the link for you

https://acurazine.com/forums/perform...8s-19s-911877/


another thread that you might find useful

https://acurazine.com/forums/perform...-4g-tl-931839/

The two links above give you a lot of details about our car and what people are doing to extract more power from it.

Finding someone to do a comparison test is best, you may also want to look at your plugs,fuel being used etc. also you can disconnect the battery so that the ECU can reset and then adapt to your driving style. Just throwing out some suggestions for you to consider.

8.7??? Something is very wrong - trucks are blowing you away at that rate. I would have your car checked out, maybe you've got a torque converter issue or something

I tried vs a truck and he won easily almost every car won against me ... it was a joke and i didnt tried vs mazda 3 and nissan sentra se-r i was afraid to loose lol

Maybe torque dont give right information but for l/100km and other stats its the same information at the inboard car so i think its the real one. I use bluetooth obd2 adapter ... i did 8.8 sec 3 times and 8.7 was my best

Evil, I have 09 AWD and i've never had a situation where the car goes from 1st to 2nd back to 1st. When I'm in manual mode it will only shift when I hit the paddles. When I have dragged someone from stoplight say a nissan max, what i have done was in manual mode I hold the parking brake, hold the throttle at 1/2 and let brake go...the car will settle and take off like a rocket....well a very heavy slow rocket, but it's still much faster than the 8.7 u get. fastest time was 6.3 times taken with gps timer with friend in car checking.

" Evilsabc" in post #6 I mentioned that I would not launch the Auto on our car. Brake torque launches put tremendous stress on the drivetrain, torque converter especially due to the heat built up. As you might be aware, the torque converter on our car is already problematic and it is not a cheap repair.

As suggested, you should look at the small things first to see if it provides any improvement,if not then have the car checked out by a professional to eliminate any mechanical issues.

Bad torque converter more than likely.

maybe you have a stuck brake caliper that's holding you back! If the car feels like crap under 2500 RPM, it's def the torque converter. It should start putting you back into your seat around 2K.

you're never going to get the results you are looking for, using the app torque.

your testing technique is faulty.

There ain't no way I'm doing over 6 Sec 0-60. I never time but off the line 370Z and even Type-S TL or WRX ain't touching me off the line. 6-Speed Life with the drop in K&N Filter and Axel Back Swap lol.

what you just wrote, confirms and makes me even MORE confident that the testing procedure is at fault.



a 1/4 mile track is a great indicator and test on how powerful your car is.

The question is how far torque is innacurate ... it cant be so far away from the real hp torque and 0-60 ... i looked into severals forum with people using torque with their car and the number are near the real number ... anyone using it in their acura ?

This thread had me curious, so for kicks on a country road I stopped, and had a friend film the 0-60 of my '12 SH-AWD. Only did one run, and i'm by no means a professional racer, but in S mode with traction control off we got just under 6 seconds on a crappy iphone video - by no means a realistic test, but plenty fast for a daily driver lol. my tires are complete crap at this point, stock michelins with almost 38000 miles, they don't grip nearly as well as new. I think it would be better if those were changed out.

My honest opinion.....I think that is about normal for the 5 speed Auto, Manual is a totally different car and much faster, I have no experience with the 6 speed Auto.

I know that many will disagree with me on the time but it is not easy to replicate posted time that we see in magazines. At almost 4000 lbs our car is heavy and there is significant drivetrain loss with the Awd system. These were some stats I found for the 2009 SH, it is conceivable that many drivers would add at least 1 sec to those time. I am no expert and others may have different experience,just sharing mine.

SH-AWD Sedan AWD 5A 6.0 sec 14.8 sec @ 97 mph Car and Driver
SH-AWD Sedan AWD 5A 6.5 sec 15.1 sec @ 95 mph Car and Driver
SH-AWD Sedan AWD 5A 6.5 sec 14.8 sec @ 96.9 mph Motor Trend
