i have a bone stock 04 auto tl with 102k miles. i borrowed a friends g-tech pro, input all the info as best i could. total wieght was about 3950. it was about 65 degrees outside and the road was flat

i tried a few different launches and the best time was achieved by turning off the vsa and stomping on the gas. holding the brake and reving to about 2k rpms and releasing the brake gave me a slower time. ss didnt help since the auto shifts from 1st to 2nd on its own. i didnt try "L"

anyway to improve this time without any mods and without lowering the weight? is there a better way to launch?

skippyTL

Dunno... But 6.6 is pretty good especially considering 102k miles.

Most tests I've seen on an auto range from 6.2 - 6.8. So you're running pretty strong.

LaCostaRacer

^ ditto 6.6 seems pretty good for an auto. The SS should hold 1st as long as you don't let off on the gas- it will auto-shift the moment you let off. I agree that the auto shifts pretty good on it's own so it may yield the best time even if SS holds 1st longer with full WOT runs.

I have the dynolicious application on my IPod Touch, but have yet to get a good run in. I can't find a great place in Northern San Diego to go for a run with my car that's safe.( I wish the Palomar Road drag strip was still open.) The best place I have now is the on ramp onto 5 North from Canon road but it's hard to get a good run with all the traffic (during the day anyway). For anyone with an IPhone or Ipod touch- the dynolicious application seems pretty good- just a 12 buck download.

I'll be going out to the desert in a couple of weeks and hope to get a run in there. I hear the GTech gives more optimistic times than a drag strip clock would perhaps off by a couple 1/10's of a second. Supposedly the dynolicious is pretty close to a real time slip posting. I'll post my results when I have them.

TL|GTX

i guess they changed that in the 07/08 TL's tranny bc if i put mine in ss it holds 1st at redline and keeps banging off the limiter if i dont change it.

ballerjai

Not bad, considering auto also.

3950 pounds??? That's way too much, what did you have in the trunk lol

6.6 sec 0-60mph is pretty good considering you were almost 4000 pounds!

libert69

iTrader: (7)

i weigh about 260. 15inch sub with 2.5 cubic foot box is about 80 pounds. plus and amp. and a duffel bag for work thats about 30 pounds and some other junk lol

yea in the earlier years ss shifts from 1st to 2nd on its own. i had an 07 tl loaner for a day and didnt realize it doesnt shift on its own in ss mode and i bounced off the rev limiter and almost sh*t my pants

erick3

a full tank of gas can weigh up to 100 lbs!

erick3

i think, THINK, my best 0-60 was under 6 seconds...? i wanna say 5.6? (fully bolted on)
used dynolicious though...which i've heard is just as accurate as the g-tech

Dave_W

If I remember correctly,gas is about 7 lbs a gallon. I just did 0-60 in 6.3 sec in my auto not even trying. I had 3/4 tank of gas. I weigh about 200. Ofcourse I have 82k miles, and I'm slightly modded. Your posted numbers are good. I'll break the 5 second range on another day.

lldknyll26

i did 5.9 with auto (TL-S). is that a good number?

Majofo

bingo.. same happened to me

I do 0-60 in 4.3 in my 5,000lb Jeep ;-)

Majofo

4.3 gallons sounds about right..

Burnricers

lol ^

And 5.9 with an auto TL-S seem about right to me.

pokin

6.6 is perhaps as fast as you could get with the stock auto. 6.8 to 7.0 is about average. The 65 degrees temp likely helped a bit.

cKHyper

what about supercharger in a 07 TL-auto
I haven't tried it really yet...but I was told the measuring bar is under 5 seconds

erick3

i'm confused...the bmw (was looking around) website says that the 335i does 0-60 in 5.6 seconds... there's no way i'd be able to keep up with a 335...

libert69

iTrader: (7)

i know the g-tech isnt totally accurate but the best 1/4 mile i ran was 15.1 at 96 mph tonight. 65 degrees out again, vsa off, using auto. ss was slower

alexSU

iTrader: (3)

Yeah I think they do it just a little bit quicker. That's a pretty conservative number.

alexSU

iTrader: (3)

That seems pretty accurate actually. Take out the system, less gas and your looking to be in the high 14's

lldknyll26

BMW advertised it like that intentionally. When they first introduced the 335i, it was adv as 0-60 at 5.4 sec car because of the previous m3 model. If people knew the car was just as fast as the previous m3, who would want to purchase the m3 over the 335i. BMW is always under-rated. Even the 330ci was under rated. It had less hp than 2G TL-s and was still able to beat it.

Majofo

sub 5 seconds in a TL..yeah.. down a real steep hill.. drive it off a cliff and you'll get to 60 mph in less than 3 seconds..

I hate cars

One thing the mags do is just stomp the gas to the floor. Most of them state this in the small print. In a turbo car you will see great benefits by powerbraking and getting a few psi before you release the brakes. That's why cars like my GN were rated for high 4-low 5 second 0-60 times and high 13s yet the owners could typically knock half a second off of those times with a correct launch. I guarantee a stock 335 would do 0-60 in 5.0 with a good driver.

As for the TL's 0-60, don't stress too much over what a g-tech tells you. I've run them in the car down the 1/4 and the g-tech usually shows a quicker ET and the mph is very optimistic.

cKHyper

well he is a good driver..he said he got high 4s and low 5s
and i got high 4s as well i tried it ones
around 4.8-5.2ish to 5.3

I hate cars

I will guarantee you no FWD car on any sort of street tire with any amount of hp is going to pull a sub 5 second 0-60.

Majofo

who are you talking about? did I miss something?

cKHyper

i'll give a shot again this week lets see what i get!

ngg19

Exactly right. The strength of our cars, at least 6mt version, is 3rd & 4th gears; and our cars are tough to launch too. And, so what if our cars are just 6.4 vehicles, that is still plenty fast.

Majofo

.. 1st & 2nd have a greater gear ratio.. so how could 3rd & 4th be the 'strength of our cars'? speed vs. time is almost linear in 1st & 2nd.. every gear after it tapers off.. the weak link for a fwd vehicle is traction.

<{Kris}>

Ya and when do you have the least traction, 1st and 2nd. Although I really can't see too many TLs with enough torque to spin its tires in 2nd.

erick3

lol i do that all the time when it rains! i have terrible summer tires on...hahaha works even better when i'm going up a hilllllllll lame...

ngg19

From my perspective, especially first gear, my car feels sluggish almost as if the gear has an rev limiter around 3.5-4 rpm; 3 & 4th gear feels fairly fluid. I can get past 6 rpm in first gear but the car never feels real balanced. For comparison sake, a 3 series bmw revs freely without that limiter feel; perhaps it is just the inline six because when I test drove a s2000, first gear had the same feeling as my TL.

I hate cars

Think about it this way, if your car pulled 3rd gear like it pulls first, you would be very happy.

alexSU

iTrader: (3)

Technically that could never happen right?? I mean there is always more power in 1st.

Unless you have way too much power and can't put the pedal down until 3rd, like your GN.

I hate cars

Definately. Acceleration always falls off unless the car has big power and traction issues. On some sort of street tire I think mine pulls harder in third than first or at least it feels like it's planting me in the seat harder. It seems to have more traction once it's moving. I've noticed that when it tries to spin in third it takes chunks out of the tires instead of smoothly removing rubber so something changes at speed but I'm not sure what it is.

Majofo

If you have the right tire, spinning in first shouldn't be an issue. Getting past the initial resistance should prevent spinning.. so basically don't hammer the accelerator until your tires bite. 2nd should be a non-issue.

If you check out almost any timeslip for the TL.. the acceleration rate is almost twice as high from 0-60' than 60-330' moreso for 330' - 660'.. sure the 3rd & 4th gear feel fluid because they're a lower gear ratio, very linear revolution. If my car pulled 1st & 2nd like 3rd or 4th I'd be annoyed.


Like Chuck Norris, Matt gets every gear down, and if the transmission / shafts gives him any lip he kicks through the floorboard and Fred Flinstone's the rest of the way FTW!

I want a car that pulls harder in 3rd lol maybe the turbo TL will make that happen. I don't see it having any traction in 1st and most likely in 2nd either.
