Went to the drag strip here in town and was very dissapointed in the TL-S. With Comptech Icebox and catback exhaust the best out of 10 runs in the 1/4 mile was 14.9..to me the TL should have run better than this...are these results right for the TL-S?

 

were you using light weight tires/rims..........did you remove your system???This could have something to do with it,or not

 

Post the slips. 60' times?

 

your system probably weighs a good 80lbs, take that out and your spare and gateshift and you'll pull much better times.

 

get some UR Pullys also, you'll be mid 14's

 

The car is only as good as teh driver

 

ouch lol

 

 

The system was not in...my car is an auto and my best reaction time was .658 on a .50 being the best possible. My car is an auto so there isnt much driver error. The track was really slow considering i chirped second with an auto..ive got video.. but here are my 3 best times...
.50 fastest possible launch

Reaction-- .813 -- .658-- .877--
60'-- 2.328-- 2.355-- 2.323--
330' -- 6.390-- 6.429 -- 6.429--
1/8 mile -- 9.645-- 9.697 -- 9.711--
1/8(mph)-- 75.59-- 75.24 -- 74.08--
1/4 -- 14.842 -- 14.915 -- 14.955--
1/4(mph)-- 95.06-- 94.65-- 94.15--

every race..ws6..z28..GT...i beat them all 60'..every race with stock wheels and BFG G-Force KDW. Burn out b4 each race..lowered pressure down to 20 lbs.. Still spun first gear with a lot of wheel hop

 

try using the SS next time............start in 2 to get a better launch......maybe look into some Nitto's for better traction

 

i tried all of it...ss...manually from 1 to d4...and regular d5...start out in 2? wouldnt that kill my launch with no power?

 

beat me to it lol....he must drive like my grandma

 

yes let me tell you i hae it 1/4 throttle all the way down the track..with vsa on

 

Yes and No you need to rev and then drop it in..........takes a little skill......Dont do it if your not sure Keep your head up and try again you''ll do better

 

hey turn that VSA off.I didnt see you posted that................That killing your time also...........WOW

 

yea its the vsa....

 

o yeah vsa was definatly off...so u are saying to have the car in nuetral n then rev then drop it into drive?

 

I don't think the TL is known to be a 1/4 mile car. If you want to drag race it, you need to set it up for drag racing. Your times are probably not far off from the best that the car can do, in it's present set-up.

 

Word..you should go to the track for fun, not looking to break any records in the TL, it's a luxury sedan not a EVO

 

NO!!!!!! You don't want to do a neutral drop, talk about killing the tranny. Just foot on the brake, while in gear, step on the gas to get it revved up a little bit, I find 1500 rpm to be good.

 

1 word...nitrous. LOL J/K

 

damn i couldnt imagine droppin the gears on the TL.....it would probably just break in half and fall out of the car after that much abuse!

 

 

No it wouldnt. The tranny on the TL is VERY stout. Our trannies arent braking from weak parts or too much power, but clutch material wearing out faster than it should due to size and heat

 

Neutral drops in an auto by nature are just not good though. I went through a couple trannies back when i was 16-17 (10 years ago), by doing that. I would never think to do that in my TL-S

 

Honestly... for those 60' times those are decent times.

A 2.1 60' would have resulted in a mid-14 second pass.

And whomever said start in 2nd for a better launch must be high

 

ditto.
reaction time makes no diff for ur 1/4 mi time.

60ft is one the most important items to improve.

for every .10 u drop on the 60ft, u know off .2-3seconds on ur time.

try working on ur launch and do some wt reduction, nothing in trunk, jack and spare out,
less than 1/4 tank of gas, 1 gallon equals 7lbs, decrease front tire pressure to get more traction, turn off all accessories.

these are just some hints that i have learned.

just my 2 cents worth.

 

check your 0-60ft to be 2.2-2.3 sec.. as for your modification i think is time to put some headers and a pulley on your car.. catback will not give you much gain ..
for your starts.. torke brake between 1500-2000rpm .. check your tire pressure.. if you spin on start maybe try 25lb-30lb of pressure max.. between each run cool down the car for 20-30min , remove the plastic on the intake manifold and put an ice bag on ..

 

First of all I have not seen many TL-S's that stock that run much faster then 14.70 so your not to far off. As for running low tire pressure that would only slow you down and create drag. You are using street tires not slicks. Slicks work on high HP cars because they grow once they get moving to reduce drag while still maintaining traction. You will never set the world on fire with a TL-S at the dragstrip no matter what you do. You can however win alot of bracket races if you get those reaction times in the consistant .520 range and your cars ET within a few thousand every run. You have a huge advantage bracket racing with an automatic. They are much more consistant then alot of the faster stick shift cars. Most of them will be giving you a head start and if you cut a good light you will force alot of mistakes. I think you should stop trying to be fast and work on being good. You can be a track champion on a riding mower if your consistant.

 

One more thing. Skip the burnout. There is no need for it. All it does with cars like ours is adds heat to the motor. I would drive around the water box and stage the car. You might find that your car runs a little better stone cold. The above idea about icing down the car is great. It works. Make sure you use plastic ice blocks or an ice bag. This will keep water from gettong into your plugs when it melts.

 

great feedback guys..the only thing im doing next is pully and headers..then its to suspension...

 

The ice think definitely helps...I did that on a dyno run and the results were great. Don't remember the #'s but there was definitly a gain after icing it down.

 

yeah that ice idea sounds great...ill try it 2mrow nite..im gonna double wrap the ice bag to insure no leaks...

 

Nothing wrong with a little ice melting on the intake manifold

 

While the burning is not necessary, it help warm up the tires to make them stick for which results in a better launch

 

last few post are pretty good . . and to add on the burn out, I by pass the water, but I do a quick little spin to clean up the tires . . .

one other item, what was the humidity . . if it was high that could have knocked you down a 10th or 2.

a quick note here, 20lbs could be too low depending on the tire/wheel size. What I mean here is that by underflating the tire you could end up with a smaller tread contact area and it would hurt your traction . . . you might try bumping up to 24lbs or a bit more.

Ruf

 

Might want to reduce some weight on the car...take out any unwanted weight from the trunk or whatnot... That will help a lot...

 

You Seem To Be Haveing The Same Problem Figureing Out While The 1/4 Mile Time
On Yur Tl-s Is So High, I Spent The Day At The Track Yesterday, And I Made Four Passes, And The Best Run Was A 15.6? I Just Dont See How The Specs On The Stock Tl-s Say 14.7, And My Stock Tl-s Runs A 15.6 Some One Please Give Me Some Sugestions On Why My Car Is Running So Slow, Because My Reaction Times Were Killer, I Won All Races, But The 1/4 Times Sucked

02-tl-s Nbp-stock

1st Race 99 Maxima V6-smoked It
2nd Race 03 Rx-8-beat It By Maybe 2 Cars
3rd Race 94 Supra- Won The Race Only Cause Of My Reaction Time- He Ran A 13.8
4th Race 06 Eclipse V6 6spd-i Won From The Reaction Time, He Ran A 14.9

I Need To Find A Way To Get Some Top End- Open For Sugestons

 

You need to remember to take weather and other factors into the results. Weather plays a roll in those times. Also were you gate shifting? did you brake torque the launch? how much gas was in the car? What type of fuel are you running?
