Okay, so I finally went to the track for the first time tonight and it was an unbelievable experience (had butterflys before first run and I do not know why)! The temperature was around 95f and was clear. I ran four times and it took me a few times to get used to the process of lining up and going. Below are my times for my first tracking of the 55. After reading so many threads I was kind of disappointed because I thought my car was going to be in the low 12's? I was running on my 19" forgestars and new nitto invo tires, but I did not burn out or anything, just lined up and went. Tried manual mode, sport, and esp on and off.

One time down the track I almost spun the car out for like 300ft with the esp off, woops. Any suggestions guys or is this typical #'s for stock car with larger h/e, meziere pump, and split cooling setup? Thx.

 

BTW, I had reset the ecu at the track right before going and racing. The only run that felt good was the last with esp on and in sport mode (13.461). It shifted well into the 6k rpm range, but the other runs the car was not revving quickly so I was shifting around 4k rpms and the pedal felt super heavy.

1st Run in Manual and esp ON

dial R/T = .607
60' = 2.180
330 = 5.886
1/8 = 8.197
MPH= 81.28
1/4 = 13.849
MPH = 98.45

2nd Run in Manual and esp Off

dial R/T = .054
60' = 2.213
330 = 6.074
1/8 = 9.258
MPH = 76.86
1/4 = 14.352
MPH = 96.21

3rd Run in Sport and esp ON

dial R/T = -.104
60' = 2.362
330 = 5.951
1/8 = 8.861
MPH = 83.65
1/4 = 13.461
MPH = 109.21

 

I don't reset the ecu or tcu at all anymore,iv noticed most times that it has pauses on shifts when you do it right at the track.

What I do that works best for me is.

Car lowered s2
small burn out
Esp on during the run
And have the car in S D it will redline all gears that way!!!

your last run would of been a mid 12 if you got your 60 ft better.

Its not so easy is it lol,I went last wednesday and thought for sure I would break into the 11s and ran a 12.028 and couldn't do it all night

 

Why is the 1/8 mile so different between runs #1 and #3? You pulled an 8.1 on run #1, yet seemed to die off at the end of the run. I think with an 8.1, and steady power and traction after that (I would hope), you would be in the mid 12's easy...

I just pulled up the first E55 on dragtimes with an 8.1 sec (1/8 mile)

12.450 113.713 8.105 89.430 2.000 Mercedes-Benz E55 AMG 2005 Jrocket

Someone said this would help.. Im not sure

 

Try this next time

tranny in SPORT
suspension in COMFORT
ESP off just for the burn out
I assume that you're on street tires, if so, just do a quick burn out to clean up the tires
shallow stage your car, stop as soon as the second set of small yellow lights lit up
ESP back on
manually shift your car down to 1st gear
roll into the gas on the third yellow and let the car shift by itself.

 

Lol you guys missed the part where he said it was short shifting at 4k.I have over 50 passes in my car,if you put it in comfort and s1 not sD it wont redline every gear.

I trap 2mph higher everytime just from having the car say S D instead of S 1 on the dash

 

Ive seen this before, I'd be willing to bet that you did not have a clear idea of were the finnish line was and were letting out too early. you can tell by the crazy changes in MPH. All in all 109 is not bad...

 

+1. On a dark night at a strip that I was unfamiliar with, I ran 12.7@98mph because I let off way early worried that I wouldn't have enough breaking distance. It didn't help that my night vision is crap. The tree operator was nice enough to tell me not to let off so soon.

 

Where did you end up going last night?

Don't worry about it, the first time at the track is always a little nerving, especially if you haven't gone before with prior cars. My first time to the strip was the E was definitely not that desirable but after 5 runs I was able to go from 13.1's to 11.8's. Here's a link if you're interested in doing some reading. My mentality has changed quite a bit from what I posted in this thread...LOL!

Keep your chin up and get out there and practice your 60' times and better ET's will come, I promise.

I just read through the post from 2008 and I can't believe how far you have come.. I can hardly wait to do my first 1/4 mile.. Virgin hahah

give us some warning next time you go out and maybe we can put an amg crew together. i'm wanting to get my car back on the strip but i need tires...coughHOOLEYcough

 

Practice makes better...You should get your 60' below 2.0 after another trip or two, then just stay in it...There's always plenty of room before the last turnout...95 ambient isn't gonna help much either...I'd hot lap just to practice your launches next time.!

 

What were your 1/8th mile traps like?

As stated, dont stop short. 8.1 in the 1/8th isnt terrible, but those times are definitely slow.

 

Don't sweat it my friend.

VERY few guys ever do anything good on their first night out.

As long as you had fun, and beat any BMW, its all good, ha, ha.

Listen to the guys around here, and read Chicago X's how to.

You will do better next time.

 

If you're going to reset the ECU do it before you get to the track. You have to do a few launches from a dig and do a few kickdowns from 30,50 and 70mph on your way to the track. This will give the ECU time to adapt. If you do this at the track you will confuse the ECU. These are my beliefs only, you can take my word for it or you can take it with a grain of salt.

 

Thanks everyone for the comments!!! I will definitely be going out again sometime soon. I went to firebird which is about 10 miles from my house, so I can really go at anytime now that I am not afraid lol.

 

I think with more practice and your guys tips I will definetely do better next time out. Practice makes perfect or at least better lol.

Sounds like a good idea I will try that on a run next time

The first times I think I let up a little early too, but the last few I went all the way through.

I went to firebird. I will definetly go back again and will get better. I think I am going to be addicted for some reason. The need for speed has gotten a hold of me, and I will be sure to read through that whole thread.

Aren't we all lol

Sounds good chiro! I saw an orange c63 there, but the guy was even worse than`me and could not even stop at the right place where you are supposed to launch lol. He kept running low 16's. Let me know when you want to go and we can meet up on a Friday or Saturday night.

You think I can get it under 2sec in street tires?

Thanks for the support! I will be reading as much as I can now that I am hooked.

I edited the original post to have the 1/8th trap times in there, what do you think?

That is what I was thinking, but I did not want to be speeding the whole way to the track because I thought if I drove slow the car would not shift as quickly haha. I am a noobie.

 

BTW, my car put down 420whp and 480wtq at dyno-comp, so I think my car should be a lot stronger since it has some of the highest stock #'s that I have seen people post on here.

 

most 1/4 tracks have cars that can run 8 sec or better times. theres more than enough room to stop. never let up until you pass thru the traps. once the time boards are behind you then get on the binders.
try steele al. there are no lights past the timers!! talk about nerve racking! once i saw an 8 sec mustang (kenne bell blown 5.0) run down the track i no longer worried about it

 

That just shows how different dynos read and why you should go by trap speeds and just use the dyno for tuning.

My car on my dyno puts down 433whp and I trap 118-119 and when I had a 180 pulley I was putting down 46xwhp on my dyno,on yours it might of been 500 or 450 so dont just go by your dyno.

 

83 mph is still a tad low for the 1/8th. You should at least be at 88-90 if youre stock. Maybe the tranny affected more than you thought, get that sorted out before you head back.

 

Hey Mikey33,

Just so you know, Firebird on Friday night at 8:00 pm was at nearly 4000 DA..... In other word your traps would correct to about 115 MPH at sea level. Not to mention the extremely high IAT's you most likely had. People mention how slow their tracks are but man, you guys have it really bad!!!!

Here are your corrected times. By no means does this mean you ran this time but it gives you some insight on how your car would perform with others in better conditions. Some more theoretical info, your 60' times are extremely high which is most likely costing you about .6-.7 in your ET's. This is going by a 2 second flat 60' time. The typical rule of thumb is for every tenth you save on the 60' you get double that on the ET. Once again, by no means am I saying you ran these times but instead helping you understand why your car performed less than what you expected.

Once you get your 60' times better the better your ET's and traps will get. Unfortunately you live in a state that will never see anything below 1000-1200 feet, due to elevation and temps. You also share the same problem as us here in California....damn 91 octane gas. Most of these guys from around the country use 93 which will give better performance. This is why we can't compare dyno's from around the country, impossible.

The next time you go try mixing a small blend of 100 octane to bump you rating up a few points. Having a little extra knock protection isn't a bad idea, especially with the heat. I promise the performance of your car will increase.

 

last time i was in LA -- my car was a beast compared to Vegas -- Doing a 1/4 in vegas is probably a huge handicap. We have the HEAT... elevation of +3000ft and 91 octane.

I have seen it posted many times but i dont understand how to get the DA -- and I dont know what is good-average-horrible. Is there a link to explain?

 

Definitely under 2.0 with some practice...I pulled 1.8-1.9's consistently the few times I've gone...that'd be nice to have a track that close
