SL55/63/65/R230 AMG: 1/4 Mile Times?
Thanks,
Mike
Made some passes at 124 MPH but all around 11.90.......
Traction is the issue not HP!!!!!

The 124 is impressive, just can't get the ET down with such slow 60' times!!!!
The Best of Mercedes & AMG
Chas ran his 625Bhp CL600 to 11.44 with DRs so comparing on paper:
Treynor's SL65 is at 542 rwhp AFAIK, so 669 Bhp. He's expecting 11.2s and IMHO, that's well within reach.
Treynor, let us know alright? You're our man!
You all don't understand the traction issue this car has at the track. You can tell by my 11.9 passes at 125 with 1.95 60' times. Even a well prepared track results in wheel spin through first and second. Even with 800 HP traction is the limiting factor, more power = more wheel spin and more ESP intervention.
F430 runs 11.7 (if i remember right) when the sl65 does in dat range.
but one is v8 4.3L N/A and another is V12 6.0L biturbo.
i was thinking the sl65 is at least getting under 10 seconds....
i dont really know the detail specs of sl65 and f430, but the question was
raised when i read the thread..so had to ask.
Plus the C&D and Road and Track 1/4 mile was done on a slightly downhill sloping track at Fiorano. Some ppl say that the 11.7 is actually a computer calculated figure as apparently they didn't have access to a 1/4mile straight at Fiorano.
Anyway, I do believe the F430 is capable of that ET but it's a totally different car.
Off topic- there's an Oct 2004 article on Motor Trend that puts Enzo, Carrera GT and Ford GT (latest test car) head to head. Ford GT does 11.2@131mph (Enzo 11.0, Carrera 11.1). IMHO, amazing Ford GT and expected MSRP$150k below cf. Enzo $630k and Carrera $440k.
Actually, <3300 lbs. F430s are light, and they launch well because the weight bias is rearward. It looks to be a hell of a car, although there's always the Viper and new Z06 for half the price...
You are correct, in dyno mode ESP will not be a problem. Until one of us get an SL65 to the strip on some sticky drag radials I am afraid we will not know. From what I have heard on some of the E55's that are modified on DR's it does not solve their traction problems completely. If a 580 HP E55 still has traction issues then a 680 SL65 on DR's will as well.
Good news! We will have a chance to play around and have some fun on May 1st when we all go to the drags!!!!! Look forward to meeting you in ATL.

my sl65 is klemanned , street radials conti 305/25/20
started the night with 12.3 and 121 and 10 runs later ended the night with 11.6 and 124.4
awesome!!!! with drag radials theis should be low 11's
:p
I'll have my RENNtech'd SL65 up at the 'strip on May 7th, on drag radials. Should be interesting.
definately need better gripping tires for the track..
are you going to run yours in DYNO MODE??
anyway thanks...
my best run was achieved with running 18 psi in the tires instead of the standard 36 that i was running and still the tires were spinning out of control.
Dyno mode is the way to go if you are not faint hearted .
even though my best run was with just ESP off
in DYNO MODE i got a 11.9 but the wheels were spinning out of control and the car became squirly in the first 20 yards..

I run the car normally, with ESP off. The RENNtech ECU lets you do burnouts with a foot on the brake - very important for drag radials! I've found that with the DRs turning on ESP loses time because it's more aggressive about quelling wheelspin, and DRs recover from wheelspin much more easily than do street tires.
It'll be interesting to see how the ole SL does. My fearless prediction: 11.2 @ 125
