Lowering your Psi won't help your 60'. On radial tires it will hurt it even more, your reaction time and the RPM you launch from will help though. Street radials don't flex like drag tires, so the result ends up being worse times from lowering them. I've never dragged, but my father did lots of drag racing in his day. I plan on maybe taking my 2nd gen to the track in the spring though, just for fun.

 

that cant be right bro. Think about it this way. When you lower the psi the amount of rubber touching the pavment increases thus increasing the amount force needed to cause a wheel hop. Simple physics

 

hmm I think it might help. People change tire pressure in auto-cross too, to stiffen/soften the sidewall (instead of increasing contact patch like drag racers do).

 

It's going to take a lot more power and a lot more traction to get into the 13s. Your car is only seeing 98-99mph. It will take atleast a 1.9 60 foot to get into the 13s and that's not happening on the street rubber. ET is dictated by traction. MPH is dictated by HP. You're going to need either drag tires or another 20-25whp to get into the 13s.

 

Shouldn't be that hard though since types-09 has done that with his normal 6MT TL with around 230whp (he only had intake, spacer and street tires when he did that). The TL-S weighs about the same and according to TOV gets 257whp, so it's not as hard as one might think.

--type-s09 - 13.968 @ 99.14 - (Intake//P2R spacer w/ 17' street tires) - CONFIRMED with timeslip + video
60'- 2.166

Also, from several websites/magazines, we have already seen the TL-S and Accord V6 trapping at over 100mph. So I say it's highly possible to break into the 13's.

 

My friend with an Accord V6 (5AT) ran a 14.9 at the track...really curious to see what i'd run since i pretty much take him by atleast 2 cars everytime we race....though i doubt i'll ever go in the TL.

 

^ then run your TL.

Thanks mod!

 

No problem. I will scan and post any TL/CL mag articles that I may come across.

 

The amount of rubber touching the road decreases when you go too low. The outside of the tires do most of the work while the middle of the tire is barely touching. You're not going to get any wrinkling effect on street radials. You need the super flexible sidewall of slicks for that. You're also increasing rolling resistance with the lower pressure. I can almost touch 130mph on drag radials but it's a few mph lower on slicks and 23psi. The tradeoff is the nearly 1.5 second quicker ET.

 

Call this '07 TL-S, 5AT "confimed" and update the times on page 1.

1st time at the strip. Had a blast, but the car just *wouldn't* go any faster no matter how hard I pushed the pedal - .

Good conditions: 65* early / 60* at the end. Minimal wheel spin; Front pressure 3 - 4 psi below recommended. Brake torque to ~2,000 - 2,500 rpm. Removed spare, trunk tray, tool kit/jack, floor mats and all misc "junk" from the car.

Stock Wheels and Tires (MXM4's ) . With real tires, I think I'd do better. I'm happy with the times. Otherwise just a P2R Throttle Body Spacer and H&R Sports for "performance" mods. See my sig for complete list of mods.

Kept getting hooked up with the same 2 Accords - they had nothing.

Nice times for the 3.5L auto!

 

^^

Thanks. Got some good tips from the site and from F23A4. I only wanted to run 14.5 - 15.0, so when my first runs were at 14.5, I was pretty pleased. "Real" tires and an intake would probably be good for some improvement.

BTW - sorry for the poor quality video and the "commentary". lol.

 

Deff go back with some half decent tires!

 

Nice, very steady times...
What's with those accords....too much wheel spin?

 

I was going to respond to you a couple of days ago and tell that "The Rock" is an extremely quick track and that was going to be a huge advantage and tell you that you'll probably post some of the best ET/MPHs on this site. The Rock is the same track where NA bolt-on Maxima 6MTs are running 12.8s@108mph and 02 4AT Maxima's with headers and some other bolt-ons running 13.6s@101mph. I've give $200 to race at that strip. It's awesome. It's like a free mod Congrats on the runs.

 

You're right Dave_B. It felt fast and was the smoothest bit of asphalt I've EVER driven on. And like I said, even with stock MXM4's very little wheel spin which really surprised me.

There were some SERIOUS Hot Rods there too - some street, some not - and 1 Nitro Funny Car that made 2 runs.

 

Wow this was your first time and you already did so well! awesome! keep it up and post more in the future!

 

The track is fairly new so it's going to be like glass. If you're not getting much spin, then you'll have to see if you can up your launch rpms. I see your 60 foots are in mid 2.2s which is decent. If you can break into the mid 2.1s, you shed another .15 seconds in ET.

 

Dave, I am wondering how does wind speed get accounted in the time slips, or are they being accounted at all?

From my rough fluids analysis, using TL as an example:

Area = 1.5m X 1.8m
Cd = 0.27
Air density = 1.2kg/m^3
Velocity (no wind) = 40.25m/s (90mph)
Velocity (10mph head wind) = 44.72m/s
Velocity (10mph tail wind) = 35.53m/s

*I chose 10mph for wind because at that wind speed, you could hardly feel it anyways)

Power required to overcome drag force when there's no wind at 90mph: 38.23hp
Power required to overcome drag force when there's 10mph head wind (car@90mph): 52.45hp

Power required to overcome drag force when there's 10mph tail wind (car@90mph): 26.92hp

This is just a very rough estimation, but give us some ballpark figures to look at. As we can see, the power difference between a slight tailwind and a slight head wind is almost 30hp. And I guess it's safe to say at 3/4 of the track, the TL would already be going at that speed (since at 1/2 way, it's already at 80mph), if not more. And the power required to overcome the drag force is to the cube of combined velocity.

So I just want to know how does the wind speed get accounted at drag strip?

 

Wind speed is not accouted for on the timeslip.

Funny how aerodynamics work. We rented out the track for a day and I got 30+ runs in, actually had to fill up on gas once. Anyway, my runs were pretty consistant toward the end but on one run I forgot to roll my window up. I lost 2mph that run and the mph went right back up on the next run.

 

Thanks I hate cars! Just learned something new Yea I figured that drag force from air could make quite an impact. I mean the government (or some organizations) always tell us to use AC rather than rolling down the windows when cruising on the highway.

So I guess it'd help if you race on a day where you have wind pushing behind you?

 

Maybe my son should bring his recent acquisition (05 Altima 3.5SE 5MT) to that track.

 

I was thinking about if we should also include the times from the CL forum? Here are the reasons why,

2003 Acura cl-s auto

14.3 @ 101.3
60ft: 2.35s
Comptech Intake and Headers

The driver of that CL-S admitted that if he launched better (2.1 -2.2s, which had happened before), it could have been a 14.1-14.2 run. It seems like the CL members, auto or manual, can post much better numbers than the TL people (no offense...I have a TL too...). As we all know, both TL and CL are eventually the same car, even more similar than G35 sedan vs G35 coupe. They use the same engines, same suspension, same everything, except that the TL has 2 extra doors and no MT, and minor appearance differences. If I recall correctly, in the G35 forum, they combine times from both coupes and sedans into one section. I think we should do that too, so that we can see a better representation of what our car can actually do.

I don't know, it's just an suggestion.

 

I am fine with posting any CL or TL times here. I am also OK with some Accord V6 times being posted here as this is the basis for the the CL and TL.

 

Here are the times for the CL forum, enjoy

Hey Bearcat! What were the tips you got? I've never dragged a fwd 5AT before. I'm very interested

 

^check the thread by Dave_B (should be the one above or below this one).

 

You've got PM.

Also check DaveB's post/thread.

 

14.46 with lots of wheel hop.

I'm planning on a trip within a month or so and will have some new mods. I would have loved to seen what it would have done with the Innovative Motor mounts in . . .

Anyway, I'll post the results when I do run as I hope to run a very low 14.

Ruf

 

good luck man! Do you think those RE960's helped your 14.46s run?

 

what mods do u have when u ran the 14.46? were u running at a fast track by any chance? These are impressive #'s.. i'm hoping to hit 14.6 wednesday with intake and exhaust.. last time i had an intake, i hit 14.7. Time slips are posted on the first page.


nice job btw! Post your slips!

 

I described this in the general forum a couple of days back, but just noticed this area and thought I'd post here as well...

Last Saturday I took my stock '07 TL-S six-speed to Maple Grove Raceway in PA. I'm not a stranger to drag strips, but I've never tried a hard launch in this car before, so my initial pass on a fairly cold track was a timid 14.27 @ 99.73, with a 2.38 short time.

At midday, the second pass with a little more aggression off the line and powershifting netted a 14.07 @ 99.15, with a 2.25 short. The MPH was consistent with reduced air density (about 1200 feet at noon vs about 600 feet for my first pass), but I was expecting more because of the powershifting.

The next pass at around 3 PM went up in clutch smoke with a launch at around 3500 and some clutch feathering, so I went home.

It's since been explained to me (on the other string) that clutch feathering and powershifting are not the hot tips in this car because of the built-in hydraulic restriction (delay) in the clutch linkage.

I was disappointed at the time, because I felt the car had a natural 13.9 in it with a two-teener short time, and the driver didn't do his job - or as one of my sons who drives F/A-18s for a living describes it - "pilot error".

Now with advice from others, I'm going to see if I can give it another go, perhaps at Englishtown NJ on Friday.

This time I'll try to launch with whatever the track can take with a "sudden" clutch and no powershifting. The car has 15K miles with Bridgestone all-seasons on it. I've noticed another TL-S 6-speed posted in this string, with minor mods (and presumably aftermarket tires) has posted a 2.169 short time, so that'll be my goal.

Anybody got any advice? In spite of my disappointment, it looks as if that 14.07 is actually pretty quick for a stock TL-S, but I want that 13.9.

Bruce

 

Good run!

The fastest I've seen is on Car and Driver and they got 14.1s@101mph, but that was with the summer tires I believe (Bridgestone RE030). Since you got 14.07 just on your second try with all-season tires, I think that's pretty good! Perhaps if you go a set of summer tires, things would get better? I myself definitely see this car can get 13.9s. I mean the new stock 2008 Accord V6 6MT can do 13.9s without LSD and with only all-season tires, though it' also 150lb lighter or so. But with the extra 20hp, LSD, performance tires, I think the TL-S 6MT can hit 13.9s.

Good luck next time!

 

What were your launch RPM's on the first two runs?

 

Bruce, PM me if your going to Etown this Friday is a definite. My son wants to run a TL-S 6MT in his 05 Altima 5MT and he is available this Friday evening.

 

guys make sure you record it!

 

YES, please record this and show your slips!!!!

And i believe you are one of the fastest stock TL-S's!!! congrats ont he 14.07 run man, that is Impressive on the TL-s.. props.

Powershifting. wow.. glad you were the dummy for this, lol... You should get some new tires/slicks/radials if you can and bring it back there!

Also, what RPM did u launch it at? My cousin with a 07 civic Si launched it 5k+ and ran a 14.3(which was his fastest)..


SO i went to the track again 2 months ago and i'm sad to say that I ran a 14.9 as my fastest.. Car just doesn't seem as fast anymore..
Mods i have are intake/exhaust and drop and falken fk452 245/45/17..

i was and still am disapppointed in my run.

However, the weather was really hot and humid as hell that day. I felt like i lost a lot of bottom end with the exhaust...

i was running consistent 15's...

I think i will be goin 1 more time in november.

 

I don't get how type-s09 ran a 13.9 in a BASE TL 6MT with just an intake and a stock 6MT Type-s can't do better...
