I ran at the track twice tonight,,

15.5 both times but second time i hit the rev limiter

i got a TL-P with aem cai, and megan headers, shouldnt i be atleast at 15.2 or 15.1?? my headers are leaking tho, can that make a big difference? tires a bit bold too

i thought my tl was quicker then that, specially with the bolt ons,, :'(

 

should be faster... depends on the driver, temperature, etc..

 

Your 4 speed auto in the 99 TL is what hurts you. Fixing the leak in your headers and getting stickier tires will definitely help a bit, however.

 

does the leak actually cause a lose of HP??

 

Black Acc so whats your overall opinion on the headers? I know you say you got a leak, but if you could go back would you still buy them?

 

i guess so , because i felt the gains.

 

The driver makes a big difference when racing if you have not been to the track a lot of times. Also with leaky headers and bald tires, they will definitely hurt your times.

 

What were your reaction times? Maybe because you were stepping on gas when you see green. Some people like to guess the green so they have reaction time less than 0.5 secs(which is impossible to get less R/T if you see green and gas because our minds cannot react that fast i think). So if your reaction times were greater than 0.5 then those times aren't bad I guess.

I Went to the track with my TL-S (stock) and I was running 15.0 - 15.1s consistantly with reaction times from 0.5-0.6 and I get posts about how I should be running 14.7-14.9s. Its all about reaction time really that what gives the differences in times we get amongst ourselves.

I personally don't like the guessing green approach. Feels like I'm cheating or something when I do that.

 

My reaction time was good, i got a .610 and .970 , ive gotten a .502 on my previous car i react pretty good to the light. I just hope its the tires and maybe the leakage,, my tires spinned about half of first gear, a good 2 seconds

 

Reaction time doesn't matter, it's all about your 60' times.

 

Reaction times are important when racing someone, but they do not count in the ET.

 

Reaction time does NOT figure into your e.t. It is provided so that if you race a friend with an equally quick car both cars may run a 15.1 but the first to finish wins, therefore the guy who skillfully left first will win. The reaction time of the winning car will always show up as lower than the guy who was sleeping. Two top fuel dragsters could race each other....on green one leaves and the other one sits there 20 seconds...both could record 4.50 runs but the rule is the first to finish wins. A look at the two timeslips would explain the loss....equal e.t.'s but someone was sleeping. Think of quarter mile races as two races. One is to leave first, the other to cross the finish line first. A moped could beat a Viper if the Viper driver sleeps at the line!

Now about those times Black Acc.... A lite UR crank pulley would drop off a tenth or two. Empty the trunk before you race incl. spare, have less than 1/4 tank of gas and go on a cool day if you can. Try a run in D3..powerbreak to 1500 rpm's and try to launch with minimal wheelspin and just hold it to the floor. Let us know how you do.

 

Black Acc if your 19's are on that could be hurting you in total weight of tire plus rim and also if they are larger in diameter together than stock diameter you have less leverage leaving the line...like leaving in second gear.

 

i was gonna get a UR crank pulley but dont think so anymore after seeing those times, i thought i would be atleast in low 15s and my goal was to atleast hit 14s in this car with the bolt ons, a 14.9 with a UR pulley, but thats not gonna happen if im in mid 15s. I did both runs in SS mode and was revving pretty high, a little before rev limiter.

By the way my 60' was 2.405 and 2.397 and trap speed were both at 90MPH

are those bad 60' times??

 

chuckstl , you're absolutely right, but his sig says his 19s are on back order, I figure he's still on stock 16s

 

yes im still on my stock 16s

 

Ahh there's the problem. My 60' is in the 2.25 range usually...for reference my 14.995 (close!) was at 93.16 mph with a 2.27 60' time. Now when you go back lower front tire pressure to 25 lbs and have your car as light as you can get it. Run on a cool day and ALITTLE tirespin is OK....work hard at a good launch. Remember that if you go from a 15.5 to a 15.1 at approx. 91 or 92 mph you are ahead of yourself (your slower run) by approx. 53 feet at the end of the track. That's a big gain. I would never take my pulley off as the gains are great, you can definately feel them. Keep in touch.

 

While reading through the thread, I was wondering why everybody was talking about the R/T, instead of asking you about the 60' times. Totally pointless.


You will have to work on your launch skills. I'm not saying you suck at driving, but there's always room for improvement. Your trap speed of 90 mph is nearly identical to my 90.02 mph trap speed when my '03 Type-S was bone stock. I hit 15.2 E.T with a 60' time of around 2.29x-2.31x (somewhere around there, I'm not even going to bother looking through all the time slips to find that one).

Usually, a tenth shaved off in the 60' time is about .10-.20 off the 1/4-mile.

With that trap speed, your car is definitely capable of running low 15's. Practice your launch skills, and run more than twice at the track next time.

 

Why are you concerned with your 1/4 mile time if you have all the excuses as to why your car isnt 100 percent? Yes the leaks make a difference, yes the wheels make a difference, yes the r/t makes a difference (especially if you are talking about .3 or .4 of a second) fix your shit and then run if for real, then let us know what your time was.

 

because i wanted to see wat i would run before i got my 19s, dont wanna put new tires on stock rims, but i think i mite just get 2 new real good tires just to run again and fix the leak. and the r/t does not make a difference in the 1/4mile u can sit there for 3 seconds, timer will not start until u leave.. r/t only makes a difference when racing.

 

Well, because, you idiot, he's trying to compare his track results to those of others'. And while in the process of the comparison, we need to take into consideration what kind of problems his car currently has, so we could compensate for that.

And no, the R/T has absolutely no bearing whatsoever on the E/T.


Fix your mouth, fix your knowledge (or lack thereof), then come back and talk to us. He's just trying to learn about the whole track thing. People like you with that attitude aren't exactly encouraging. And that's not what this forum is about.

 

First off....he is asking if his header leak will make a difference...which it does. Second, he expected his TL to be quicker than it was. I am not blasting him for having those problems at all, just did not understand his intention of the thread. Dissapointed with the TL performance with those problems that needed to be fixed. I'm not saying he should not have run the TL to see what the time was, but should in no way be dissapointed in his times because he had those problems. Yes I was mistaken about the r/t....I run a different beat with that, but with the rest of the "excuses" (sorry that was probably the wrong term) he should look forward to having his refreshed TL run much quicker than expected. I'm sorry that you did not understand the intent of his question.

 

the pulley will definitely help. it not only makes your car lighter, but it also will give you extra horsepower due to underdriving the accessories and the lighter design takes less inertia to spin.

this single mod will probably get you the gain to be in the high 14's.

anyone with a 99 with intake and headers run at the track? What were ur results? please post, thanks

 

This is an interesting thread! I have a 00 TL-p and have just about every bolt on available and now i am wondering if i would be able to even crack 14's... Running mid 15's definatly was not on my list of things to do. This would be my first time at the track when I run. Realisticly, without any experience track running, what should be an ideal times? Also informative question: should i run on my stock 16"s? They have about 50% tread left on them or just stick with the 19's because they have stickier rubbers...?

 

Um, the crank pulley--or even the whole set isn't gonna knock .6 seconds off of his time. It might knock .1 off if he is lucky...It certainly makes the 1/2 transition a bit better.

I will tell you though it wasn't very hot Saturday/Friday, it was still humid as h=ll in Orlando. That being said, with an exhaust problem, sounds reasonable.

My real question is what size/type wheels and tires are you running? The high 60ft appears to be a traction/driver issue more than anything and accounts likely to a .2 second savings for you. With a good set of 16/17's that aren't godawfulheavyass chrome with some reasonably sticky tires and a fixed header leak, yoou should be around 15.1 driving decently.

Lastly, to be honest, I have not really seen any TL's into the 14's. It's just hard to do. If you're goal is 14's or even a 15.0, you aren't likely going to make it in the long run anyway if you put 19's on your car (even if they are light and have way sticky tires which sounds like isn't happening anyway). But from the sound of things with your wheels, sounds like she will at least look pretty pimp.

 

Oh boy... So much misinformation in this thread.

As stated by lots of people, reaction time doesn't count in your ET.

Your 19"s are killing your 60' time. Chrome 19" wheels probably weigh over 33lbs before you mount tires on them. Unsprung weight will really have a negative impact on your 60' time. All else equal, if you drop one tenth from your 60' time, you should lose two tenths from your ET.

Thus, If you dropped .2 or .3 tenths off your 60' time of 2.4 seconds (which is entirely possible with stock wheels and good tires) you'd run a 14.9-15.1.

The exhaust leak isn't going to hurt you that much. You are losing low end torque, but your higher RPM power shouldn't be affected that much.

A trap speed of 90 with those heavy ass wheels indicates roughly 195-200whp given your car's weight, gearing, etc.

On the launch, don't just stab the throttle off the line, ease into it until you have 100% traction. A little chirping from the wheels is fine, but wheel hop or wheel spin will hurt your times.

It takes lots of practice to get it right. Unless you are going to go to the track very often I wouldn't worry about it. You trapped at 90 MPH and that's what matters really. Your trap speed isn't affected nearly as much by your poor launch. I've made over 150 passes down the track in this car and I'm still improving my 60' times. My best is a 2.000 but I've had a screw-up everynow and then. Even I have run a 2.4-2.5 60' time (only twice)

If it were my car I'd be pretty satisfied with the results for your 1st time at the track.
