Not to bad for a old man ride ! Ill have pics when i find my digicam connector

wow! that's amazingly good.
did you leave the TC on or off? what rpm did you launch at?

off and launched at 2 grand or so rolled out a hair and punched it

Thats Awesome. Good Run!

WOW! Our cars run mid 13s?? I was thinking 14 at best!

Got a STS4, will have to check it out to see what I lose having that 4. I am planning on Corsa exhaust and Cold air.

Not to be an old fuddy duddy, but hopefully you realize that many auto insurance policies exclude coverage for anything that happens on any race track.

That's fantastic!!! I used to hang out on ls1tech and I miss everyone posting their track times, good to see someone getting some track time on this forum. Excellent time by the way, a 13 sec pass is no joke, you'll beat alot of mustangs and LT1 fbody cars.

I can't believe you posted that, C5...

I also am blown away Silver WS6 ran such a fast time. My 2001 Z28 ran a 13.6 stock and I was driving the hell out of it. I thought the best times for these cars were low 14's. You think you shaved a half second by the intake & catback??? I can't believe you gained that much from those two mods....

Not even a catback. It says axle back. Anybody know if Corsa does a catback ? I have been looking and all I can find is axle back. I also have the 3:42 rear end. Boy does it make the car fun to drive, just not by the Gas station. Nice run by the way ! Shut the traction control off ?

Traction control was off. Ive been into racing for many many years. I owned a 11 second Trans Am Ws6 a 14 flat Grand Prix GTP with a pulley and a intake with a 1.9 60 foot on a front wheel drive car. A 12.05 sec chevelle ss with a zz454 crate motor. So i know how to maximize a car even without slicks.
The K&N cone by itself was the bigest gain. Its hard to explain how much of a increase it is. I did it to a prior cadillac my dad owned and it droped the 1/4 mile time by .3 and .4 depending on the run. its no joke !

for those who know drag racing if you look at my 60 foot on stock tires and my reaction time you know that i can drive the hell outta this car

do you recall what size# filter you used? and a pic of how you mounted it would be great too, although I suspect it's easy... thanks

i dont remember but i can take the dimensions for you in the next daty or so. i wanna say it is RE9040 ??

That's crazy that a freakin air filter/intake made such a dramatic increase. I was under the impression that only the 1SG cars with AWD got the 3.42 gearing.... was that 3.42 gear part of some other option as well?

as far as i know it came with a performance option I may be wrong it sure doesnt feel like 3:23's and if i had 3:23's and ran those times im getting some 373's :)
IM 1/2 temped to do a throttleody bypass and start calling places/friends who can tune cars well and take a crack at my car to remove torque management and throttle responce and fans and WOT AFR :)

Was the track "rubbered up" before your run. I can't imagine that timing with the OEM rubber. Did you burn out before the run? How the heck did you get them to stick. I have trouble getting traction on even the hottest July days after driving for hours.

a nice smokey burnout was done everytime :)
and also the track was hooking really well. ! Cecil County does a nice job prepping the track. Its all about when to give it gas and how much its hard to explain but a little roll out at part throttle then punching it works the best.

I can't believe you posted that, C5...

I figured I deserved some abuse for that. :thumbsup:

the big factor for those great numbers isn't the exhaust system; it's the 3.42gears...they give a real boost to acceleration times...not great for top end, but excellent for low end punch and a quick launch.

that's an awesome post. i wish i had did my 1sf before it got wrecked. hopefully i wont be saying the same about the sts-v that i have now. hard to find the time.

one thing...even with my vette...i roll out a bit too, then try to hurt it. works great.

as far as i know it came with a performance option I may be wrong it sure doesnt feel like 3:23's and if i had 3:23's and ran those times im getting some 373's :)check your RPO codes, I know the 3.23 is GU5 and I think the 3.42 is GU6

makes me wonder how hard it would be to upgrade :)

i think all rear wheel sts' came with 3.23's

check your RPO codes, I know the 3.23 is GU5 and I think the 3.42 is GU6


Can't find any options to select the gear ratio from this option list...
http://media.gm.com/division/2005_prodinfo/cadillac/sts/STS.pdf

My past research shows the following:

1SE - 2.73

1SF - 3.23

1SG - 3.42

RWD - not sure about AWD

That's interesting to read that all 1SG cars had 3.42 gearing. From what I've read, most car magazines tested fully loaded 1SG cars and never cracked into the 13's in quarter mile testing. Then again, they were new, probably not broken in, and didn't have the aftermarket intake/exhaust.

We need more data here folks, everybody head to the track this weekend!!!

Still waiting for the snow to melt here in MI...

HOw much slower is the AWD vs. the RWD? I would guess takeoff on AWD would be better but where is the slow down?

I'd like to know if you used the manual shift or the "sport drive" option? Or did you just leave it in D and let her rip? But this is good news, most of the vid's I've seen of the sts draging has been disapointing, getting beat usually off the line and never really catching up....

ok since im getting a ton of PM's here is the rest of the info .....
3/8 tank of 89 octane gas
rear tire pressure 24 psi
Traction control was OFF
put in 4 gear (not D or Maual mode) ( only ran it 1 time in D only and i think it was slower but only by a very very small margin )
Spare tire was removed for weight savings if any (but i still had junk in the car like floor mats cleaning supplies n a few books so it wasnt stripped by anymeans)
car cooled 30 min before every run and coasted to the start line before starting again and doing a smokey burnout for about 15 seconds then going to the line.
Gave it a couple second before going to the lights because sometimes my stabilitrack was engaged after the burnout and i waited untill the light was off. Which normally took 2 or 3 seconds
tached to 2k rpms or so rolled out a hair and punched it from there.

With AWD i would suggest slower times even though your launch will be better these cars dont really get into their pull power untill higher rpms so launching and getting the best 60 fot isnt going to make a huge difference versus all the weight and drivetrain loss.

bada$$ times for sure, just not sure how you got it. From everythign I've read, only the 1SG cars came with the 3.42 gearing. Correct me if I'm wrong but your car is a 1SF, not a 1SG?

An '06 AWD STS also has a five speed auto which is another variable. The option tag says 1SF, MV3, MX7 which makes it 3.23:1, five speed auto, and AWD.

i gotta look into it because after reading the list of options somone posted i have a mix of both parts !
i have a 1sf but i also have aux powersteering cooler and dual elec fans infront of the rad which is not a option on a 1sf but is on the 1sg ! where do i look again to tell which one i got ?
I tried to get a carfax vin check but since im not a supporting member i cant get it !

Go in your trunk and pull up on the flap like to are getting the spare tire, On that, you will find the codes.

Can someone explain to me why you'd want traction control off??? I'm from a 4x4 world mostly and to me having the control "on" would give me better traction ie: both rear wheels driving vs. just one side?? Or is this kind of "traction control" different from the truck world?

Traction control is pretty sluggish as implemented on the STS. If you spun a wheel a good driver could probably do a better job pedaling the car than the TC could. On ice the TC is way better than a driver.

We are also talking about being on a track and not in real world city driving.

When a driver tries to pedal an STS with TC on ice it really gets ugly.

In drag racing, a little wheel spin isn't a bad thing, keeps the rpms up and makes for the quickest times possible.

Ok makes sense, I do understand about having a "little" wheel spin being a good thing, just figured having wheel spin evenly distributed between both wheels would be better and easier to keep it in a straight line. I have heard about the nightmare it causes in the snow though...

Fifty years ago when I was taking engineering courses at the University of Alaska, if a professor saw you spinning your tires on the ice it was an automatic failing grade.

TC on the STS's uses the brakes to stop wheel spin. Brakes are not something you want to use to get that 13 number.

I just about got stuck this winter going up a small hill with about 5 inches of snow on the ground. I had reached down to hit the hazard button and by mistake hit the traction control. Wooosh .. up the hill I went... All be it a bit sideways. ;)

The RWD STS's have a limited slip differential, plus traction control and Stabili-Track. The 1SGs also have Magnetic Ride Control so you can have Touring or Performance Mode, but this doesn't affect traction, only shift mapping and handling.
You can turn off the traction control by pushing the T/C button behind the shifter (T/C light comes on on the panel). This turns off the nannies that prevent wheel spin with brake application and/or throttle intervention. Then you have only limited slip and Stabili-Track, but if you get a little crossed up, the Stabili-Track is going kick in and retard the throttle or apply a brake to keep you from losing it.
If you hold the T/C button down for about 5 seconds, the Stabili-Track is turned off (wait until it tells you it is off on the warning screen) and you are back in the 1970's again. If you want to have fun on a track day and risk stuffing it, turn it all off. Just turning off T/C makes it more fun to drive on the street.
As far as shifting, put it in sD (without upshifting or downshifting) and let the tranny do the work. It will shift at the optimum RPM and shift more quickly than you can do it yourself.

actually tcs uses spark & throttle. stability may use antilock...

I have a 1SF with several extra options too... I just checked my spare tire cover thingy and I have "GU5" code which means 3.23 rear end, so see if you have GU5 or GU6.

TC uses brakes and throttle. You can hear and feel the ABS going off. If you monitor throttle position with an OBDII reader you can see throttle position coming and going. I have seen this spark and throttle statement before and did some personal research. I know of where I speak. I don't know what the hell your car is doing but I know for sure what mine does for TC.

never heard of that, but it uses spark control, as it is programmable with hp tuners, and makes a big diff. as a matter of fact, if you program out the spark and the ETC (throttle), there is no traction control, just stability control. give it a try.

yours may be diff, but i think you are feeling stability system.

It is definitefly using ABS for traction control. You can hear and feel ABS going off as the message on the DIC says Traction Control Active. A few seconds after the message is removed the you can hear ABS again for about a second but you can't feel it. Meanwhile the stability system is doing nothing.

Owners manual page 4-9 says that TC uses brakes and engine power to control wheelspin.

Let's stay on the topic of the original thread, discussing quarter mile times & gearing options. I'm really interested to get to the bottom of this and would like to get some more confirming data.

dam i have 3:23s which actually makes it even more impressive ! i want 4:10's :)

Back in the day(1962) when I was running my Pontiac within 0.1 sec of the national record in FS/A, we figured we had the correct rear axle ratio when we crossed the finish line in fourth gear at redline.

I have the 1SG with 3:42.. and a cat back going on this weekend. I can't wait for the snow to melt off NewEngland dragway ! Just need to figure out what PSI to run the Goodyear Eagle F1 all seasons or maybe get a set of the "Summertime's":bouncy:

This is probally a really dumb question but how do you tell if its a 1SG or a 1SF?

1SG cars have the 18" 9-spoke wheels is the biggest sign...

Check the tag on the bottom side of the spare tire cover in the trunk for all your option codes.

this is a forum...there are no stupid questions.

My 05 1SE--2.73's ran consistent 14.5's last summer at Summit Motorsports Park in Norwalk, Oh. I have a Corsa Exhaust and stock 17in. wheels, with the "junk" tires on it. Lookin for an Intake. Did the CAI ever materialize?

mid 14's on crap tires and 2.73 gears is very decent, but I'm still pondering how to shave a full second with better tires & gearing? Oh, and the airbox?

Don't brake-torque it. As soon as your feet hit the gas and the brakes at the same time, the torque management system starts pulling timing to reduce torque. Sit with your foot on the brake. At the light, it's off the brake and nail it. Enjoy!

1SG cars have the 18" 9-spoke wheels is the biggest sign...

The '07 1SF cars have the 18" 9-spoke wheels also as option (code QF8). It requires the JE5 brake option. Not sure about the other model years.

Drove aCTS-V yesterday, left 4' rubber in second gear. I bet it's hot on the strip!

So what did we ever figure out here? Anyone else run their cars down the track yet this summer? Is the intake & exhaust worth almost a full second? It doesn't sound like driving really is an issue considering even brake torquing at the line kills the power so just floor it & hang on. Did this guy just have a factory freak with some grippy tires or what?
