Going to the dragstrip,have a question...
Launch pad is a bit slippery compared to most,I doubt the tires are gonna hook so should I leave the traction control on?
Should I put in M mode&paddle shift?What RPM?Or just keep the car in S mode & let the car do it?
What RPM is everyone leaving the line?
What short times are you guys seeing?
I doubt I'll see 12's cause of the 90 degree temps here,but I'm thinkin 13's are possible
I'm sure I'll have more,but these popped off the top of my head....
Thanx in advance

Keep the car in Summer mode and let it shift.
You won't be able to power load much and won't have to or you'll just spin off the line. If you can get it to 1300 or 1400 rpms, that pretty good. I get about 1500-1600 on the drag radials before they start to break traction.
Irregardless of the heat, unless you are at altitude, you should see mid 12's.
Happens to everyone, you will run in the upper 12s first time and be pissed (knowing there are guys on stock Conti's that hit 12 flat) ALL while people are dropping to their knees in worship of the car. It's funny as hell.
Good luck.
You have lots of expericence....you'll do great. It's cake...compared to walking a 400lb bike over the starting line..you even have that pleasure....scary.

Have FUN!
Rememeber the Benz torque curve is evil...unlike most motors in that it dumps the motherload of torque right off the bat, thus our love for these cars.
Try it once or twice, just be warned if you make it a habit.

Sorry for the confusion...
The fastest street-legal car(he did have Drag tires on though) there last week was a turbo Supra who was spraying the dog **** outta the car.He was runnin low to mid 12's all night & then went for broke on the last pass of the nite& ran an 11.70@132mph.
I'm so anxious to go it's like I'm a teenager about to get his first piece of ***
One other thing:will I notice any appreciable gains by running with a 1/4 tank of gas,or will that just emphasize the lack of traction?

I am one of those guys that Jakpro talks about
prior to staging
1. empty out the tank and have the least weight in the car (ESP will take care of traction control)
2. set your rear tires to 25psi
3. set your front tires to 40psi
4. set suspension to C (comfort)
5. set tranny to S (sport)
6. get to the strip early and open the hood and let your engine cool as much as possible before your run
staging
1. do a short burnout in manual mode with ESP off to warm the tires
2. PUT ESP back on and swithc to S mode
3. pull up to the staging lights
4. left foot on brake, right foot poised above accelerator - no gas
5. watch the lights - as the bulb on the 2nd to last yellow light hits full brightness - brake off and mash the accelerator to the floor and hold it there with impunity - the ESP and that awesome motor will do the rest and you will have your first mid 12 second run on your first attempt, and people will going .... "WTF - did you see that lame *** Merc toast that Vette!"
As they say its totally addicting - just like that first pice of ***!!!!
bye the way - the method I used above is just the opposite of what you need to do to go faster - that requires ESP off, preloading the gas and finessing the throttle - something that I am working on for my first run of the fall when the cold fronts move through
Bald old fat fart with 12.5 second 1/4 miler grocery getter - with a woodie for speed that just wont quit!!

My best has been a 13.4.

What should I check for? Its like my car is broken or somemthing. Feels fine, but at the track it sucks.

What were your 60' times?
Anyone else agree??

I've only been three times so far. My first time I ran under the guidelines quoted above. I thought that with the ESP on, I could floor it with impunity. That wasn't the case for me or my car. The ESP would kick and severely retard my launch (much more that it ever had on the regular street). My 60' times were horrible (2.3x).
The next time, I did everything the same except for the throttle. I feathered it at the launch, trying to get moving a bit before I completely mashed it to the floor. My 60' times were much better (1.8x).
That seems to be the trick with my car: giving it as much throttle as possible; while trying to limit the spinning; while trying not to get to the point where there is too much spinning and ESP gets too aggressive and kills the lauch; while trying to figure out at what point I get past all of that and can, in fact, floor it with impunity.
I have also tried it with ESP off and it felt as though I sat at the line for 5 seconds spinning before getting up some speed. I've come to the realization that DR's are a must. However, a number of people will be blown away that your car will run in the 12's and even more shocked that it will do it on street tires.
The more I go, the more I learn. I also did a search using "launch" that provided some helpful guidance.
Take that information, together with the track's elevation and your actual ET and trap and enter it here: www.modulardepot.com/density.php
Based upon this information, it is claims to calculate the Density Altitude and gives you a "corrected" ET and trap speed for sea level.
Realizing that this is a mathematical model, I have no idea if it is realistic or accurate. But, maybe, it would give you some idea.
For example, my best "uncorrected" is 12.659 @ 109.782 which yields "corrected" numbers of 11.83 @ 116.96.
Again, I don't know how much weight (if any) to give to the "corrected" numbers. You ultimately "run what you run." But, it might be helpful to gauge the changes in ET and trap using this program for runs at the same track, but on different days when temperature and humidity differ.

My 60 foot times suffer when I have too little gas in the car. I like to run with at least a 1/4 tank. Oh, and lower your rear tire pressure to 22 lbs.
Good luck.

I ran at Moroso and did 12.5 with ease at 114mph. This is what I learned that night (and believe me I am no expert) and this will guarantee you a mid 12 at anywhere othr than altitude

I did all that and recorded my slowest time of 12.93 and 60' 2.448 sec.
Went back to 35Psi F/R, S2 suspension, full tank of gas for traction,ESP off and got 12.35 and 60' 1.874 stock. Believe it or not...
I reminds me of when I was a kid and it would snow -- we didn't have a four wheel drive -- so we would throw rocks in the back of my dad's truck to try to get more traction. Maybe the same principle.
here are my times from my first outing................
1/4 Mile ET: 12.502
1/4 Mile MPH: 113.830
1/8 Mile ET: 8.131
1/8 Mile MPH: 88.940
0-60 Foot ET: 1.990
Temperature F: 75.0
as you can see 60ft time is not toooooo bad - obviously could be way better - much room for improvement - but nothing like 2.448 (yeah I know track prep etc.)
When you see Derek's times you gotta know there is a whole lot more going on there - the monster engine, the NOS, the DR's, the track prep and supreme finesse of the launch, etc.
The whole point of my post was to say is that it is sooooo easy to run mid 12's - just point and squirt and you dont even have to engage brain.....just my $0.02
go out have some fun and dont sweat it - when you are ready to get serious - now thats a whole nother matter

Take a long drive to a track at sea level to confirm this.
Your 60' is OK, you just haven't got enough oxygen to go the distance at full revs.
Just my luck,I called ahead to confirm they were open,(which they were)and when I got there 4 hrs later they were closed due to "Impending Weather Conditions"
But I did leave my kids car seat in the back for some sleeper effect.....Although I highly doubt that Tech wouldve let me keep it in the car,lol
