this weekend


alright i was at LACR in palmdale which is very high elevation and for my first time in the drag with the mercedes i thought i did pretty good at the end, just sucked in the beg cause of my launches

times in order

15.001
14.9
14.6
14.9
14.2 where i finnally got the hang of launching
14.189
14.12

im sure if i go back i'll be in the 13's its jsut that it was a really high elevation area in case your unfimiliar with palmdale so you gotta give me slack on that

[Chappy]

Did you run with traction control on or off?

BTW, what is the altitude at LACR?

Thanks for the info, Improviz. Good to have re: elevation, etc.

EMIL, what was ambient temperature when you ran?

[Chappy]

So, the best is about 13.66 at sea level....is that right?

not sure how to calculate it but from what i heard 13.66 sounds about right, my friends m3's best record at that track is a 14 flat


and chappy its A-M-I-L not EMIL but heh its cool

for my first run i left traction on and just stopped on the gas got a 60ft with 2.99 heh (thats horrible) thats why i got 15 seconds

so i left traction off the rest of the runs and i finnally noticed if i feather the throttle for about 10 ft thats gonna approve my 60ft big time beacuse i was getting a lot of wheelspin also oh and just so you guys know i have 265's in the back

Sorry about that

When did you put 265s in back? Are they on the stock rims?

i bought my car used from the dealership and it had the 18" multipiece rims and the tire size in the back is a 265

[Chappy]

Okay, gotcha....sorry if I'm playing catch-up here.

[CHB]

Good times I can't wait till the weekend for those vids

[Improviz]

Curious to see them...thanks!!

[AMIL]

sorry i took so long i couldnt find the timeslip

REACTION 1.606
I1 2.224
I2 6.056
I3 9.174
MPH I3 78.118
I4 11.789

E.T. 14.123

MPH 100.197

If so, that corrects to a 2.1...pretty good. For every 0.1 you shave off of that, you'll pick up 0.2 in the 1/4, so if you can get the launch a bit better, you'll definitely hit your goal of the 13's!

The best I've been able to get is by holding throttle with right foot, brake w/left, traction control off, and getting RPMs as high as possible so that I can get out of the hole fast without spin; this varies greatly with surface, though: sometimes, I can go as high as 1,700 or so, while others I'm limited to 900. Definitely a trial and error thing.

Then, without increasing pressure on the gas, yank your foot off of the brake, and a *split* second later when you start moving forward and feel weight transfer to the rear, do kind of a "rapid squeeze" to full throttle (again, how rapidly is dependent upon the surface), and you're on your way! It really takes good timing: too soon, and you'll spin. Too late, and you'll bog. Just as Motor Trend said, these things are tough to launch!!

Btw, beware of axle hop; if you ever get that, let off *immediately* unless you're fond of purchasing driveline parts and axles!

throttle with left??? brake on right??? isnt the throttle to my right and the brake on the left?? crossing my feet would seem pointless and odd

I also went to drag for the first time in my life today at New england Dragway.
Got 13.4 as my best.
My score:
R/T = 0.683
60' = 1.821
330 = 5.42
1/8 = 8.215
MPH @ 1/8 = 82.04
1000 = 11.112
1/4 = 13.459
MPH = 107.51

Lost by the moster Chevy from 1968 with supercharger(720bhp)
by 1.7 sec.

[JLee81]

above was with my 2004 CLK55 with 19 inch HRE 847R F8.5 R9.5 with Pirelli Pzero Nero 235/30/19 265/30/19 tires(Front weighs 50 pounds, so obviously the rear weighs more). Also I didn't take out the spare tires. If I could lighten up my car with the stock 17inch with Pirelli Rosso tires, which provide a better grip than Neros, and get rid of the spares. I should be looking at close to 12 sec rage. If I can push it like I did today. Keep up the good work Racer. Get the limited slip differential from Kleemann which gives 60% lock ratio. It will reduce the time. I am thinking of one.
