I did in my best 1/4 mile 15.837 with my automatic coupe!! I did that with everything stock!! i think my time was pretty good but i just wonder if ou had a better time! thanks

Mercedes

I looked at motor trend magazine, and they got a time

of

0-60 in 7.2
1/4 in 15.3

I guess this was the 02 6spd

not bad for an auto. i gotta go to the track someday.

btw- how did u launch? did u have esp on or off? and did u brake toqure it or just floor it?

Diego

I tried all the ways arounds! I did it with the esp on and off? and did also I braked before! I also tried by lowering the pressure in my rear tires from 32 to 18 psi. OF course that was in Morosso in FLorida and those day it was very hot and wet and 3 hours of driven to get there! i thinkthat made a difference in my time! Right now it's getting colder in here so with my new pulley coming this week i will try it again in the 1/4 mile! i hope i will do much better!

What did you use to measure your 1/4 time?.... I used G-tech to measure mine and I did 15.7 something seconds at 93 something miles/hour in my C200K auto (ring pulley, exhaust and airfilter)...I'm not sure if my Gtech is too optimistic with the results but I'm hoping it is true tho

Diego

I went to a professional race track called Morosso motorsport park! they use a system "Compulink" for measure times!

Diego

there is how they measure times!

eason

I got 15.7sec@91.8mph from my G-tech.
That's with K&N cone filter and auto.

The G-Tech is nice but the track is the only place to get facts. BTW, the g-tech gives your mph at the very end while the track averages your mph over the last few feet (maybe 100 feet) so the G-tech should give a higher mph. But maybe you guys know this already so if you do, sorry for repeating.

I would guess just stomping off the line would be best. That way the convertor would flash more than brake torquing it.

Nice 1/8th mile time. Not far from the 9's. Throw out that spare tire! ;-) and empty that gas tank. Too bad we couldn't make up 3 thenths in the 60', these cars have a horrible start.

Great runs!!

I live in florida to and i am planing on going to Moroso also in a month or 2 after i get a pully. where in florida do u live?

Also what pully are u getting? i am sure u will go to the track sooner than me so i am very anxious to hear the time with the pully. please post the time once u get it.

Thanks.

Diego

I live in Miami. I will go to morosso a week after get the pulley installed because i want to try the car first after run it. but whenever your planning to go tell me and we can meet over there. probabbly I will have the intercooler installed for that time some I have another excuse to go there! so by the way where do u live in FLorida maybe you are my neighbor and i didn't know it!

KompressorBabee

hehe.. didn't kno u can bring an auto to a track and hold it down about 15 secs.. nice hehe.I afraid that people make fun of me if I do hahaha...

Diego

Do not worry about waht other people say! just go and have fun! it's a cool thing to do!

The last 60 feet

And correct about converter flash... will be faster *if* the tires don't spin.

Converters actually multiply torque for a short time during launch.

BlackC230Coupe

that weird i did not even get an email saying people replied to this thread, lukly i checked it out again.

what pully are u getting and when will u be getting it? i cant wait to hear the time then. before i get mine.

oh and i live in Coral Springs, i am sure u know where that is, Miami is not to close to me, but not that far.

Don't the auto's have knockdown or something like that? I remember reading in the manual that if you want a fast start to push the pedal beyond it's max point, so basically petal to the metal :-P and it'll do a knockdown start or something. Anyone else know about that? I'd think that's the way to launch w/ the auto.

x15jq

The kickdown button past max throttle is basically used for passing on the highway or wherever max accel is needed
It brings the trans to the lowest gear possible without over revving.

Wont help your accel from a dead stop if the trans is in S mode (lowest gear start)

If you are in W mode however, kicking it down will make it go to first.

Hope that helps

i experience this a cupple times a day when i floor my car. it does only work as you are driving.

champa

I have an autobox, I sometimes left foot brake, and on busy intersections or when I need a quick lauch I brake and hit the gas a bit to help. On the ML its fine, but on the c240 sometimes it is actually worst. It feels like the car stalls for a second....any ideas

Lynn

Yes, it is worse. The auto magazine testers always say they get the best results with MB automatics when they launch by just flooring the throttle.

Matt230K

The C-class actually has something built in that won't give it gas if you are on the brake. I guess this is to prevent you from doing that and also to keep you from left foot braking and dragging your foot on the brake all the time. It seems that there are ways to get around it, you just have to mess around with it. Most of the time, the car won't go if you're on the brake though.

benzy230

mine was slow in the 1/4 mile..i think it ran high 16's

Diego

That's not good

That is not bad at all!! what do you have an auto? How many times did you try? and where did you go? I did over 16 second a couple of times but it was'nt my foult! once was because the esp and BAR lights turned on at the momento of the race! sucksss

BlackC230Coupe

hes joking about that time. i think he really ran 13's in the 1/4 mile but then he blew his engine. :p

Diego i asked u like twice already and u did not answer, what pully are u getting?

benzy230

:p :p

yeah...i ran 13's....and the motor ran excellent then..it blew because of some bad decissions made on my part
