The 63 cars are MILES slower than the 65s, even "upgraded."

I think you maybe right, I am sure the Race logic box is more up to date
and therefore more accurate.
But tell me, why do so many people say the 63 is slow,by these figure it's
pretty on par with a stock 55 which most members say is quicker. I know
it can feel slow, I have said that myself, but according to the figures if anything it's marginally quicker than a 55. Perhaps peolpe are fooled by the
55's extra torque, I know when I drive my 600 it feels faster but it's marginally
slower.I would like to know the quarters for M5 and GTR.
I have found a web that gives quarters for nearly all MB's.
It's www.dragtimes.com the T maybe a capital.
Cheers

It's probably the torque. As I mentioned, that magazine test was much slower than a Motor Trend test that hit 12.4 @ 115mph. Also, I have never seen an SL55 030 tested. The SL55 can also be easily be modded to get a lot more power (S/C pulley, headers and ECU). An SL63 can get the ECU and headers but it doesn't have the same impact that it has on a forced induction car.

M5: 12.5 @ 118mph

GT-R: 11.5 - 12.1

Thanks again, wow the GTR is quick. However the M5 time seems slow, I saw
a video on the forum recently showing a 63 being demolished by a M5.
Incidently I think my box is a little harsh, the best I got to day from the 600
was 13.6 at 105mph.

What time does your car achieve?

TMC M5

The M5's forte' is above 100mph. Look at its 0-150mph time. A stock E63 is 23+s.

My car has run an 0-100mph in 7.2s on a 1/4 mile pass where it did 11.209 @ 123.7mph on drag radials. On stock tires it has run 0-100mph in 7.9s on a 1/4 mile pass of 11.72 @ 122.8mph on my 5th run of the day without letting it entirely cool down.

We are going on 1 year with the SL63 and love it. I didn't purchase the car for quarter mile runs, but for real world driving. While I can appreciate the awesome HP of the SL65 there's more to the SL63 than outright acceleration. Recently took the car up to Skyline in the bay area and instead of having the motorcycles run me down I was the one doing the passing.

Yes, it's about 800lbs too heavy, but it handles beautifully considering it's weight and built quality.

I still haven't had an opportunity to test it's top end and I'd be very interested to see what the real world top speed is with the speed limiter removed.

Tom , your car is very quick. How is it for lag and bogging down, or does it
drive normally.
I think 0-100 is the most important, our roads are so congested and you
may lose your licence for over 100 that a time to 150 is not important.
There are immensly quick cars here. Evo's and Cateram's and kit cars that
will blow away supercars in terms of 0-100 but they often have a top speed
of 120 or less, ideal for our roads, especially if they hold the road as well.
In the states you have the roads to exploit 150+

Exactly!
I have been banging on how good it is for yonks, much to the annoyance of
other members.

Your S600 ET/Trap are way off, sounds like it hasn't been driven in while I.E. Tranny gets extremly slow, adapts to hard driving in a day or 2, also your IC Pump could be failing as well. Other members here have achieved low 12's @ 113+ mph in that heavy saloon in Stock form

member from this forum Dragtimes record Stock S600 12.2x @ nearly 114mph http://www.dragtimes.com/Mercedes-Be...lip-14182.html

Point being, when your S600 is working properly, it'll put a beatin' on your SL63 0-100 or 0-150 daily

Also from Data of true Stock M5's on Dragtimes they do not trap 118 in stock form, average Stock M5 is running low to mid 12's @ 115-116 tops, other records on Dragtimes show Heavily modded M5's running 11.9x @ 118-120mph

I agree, sometimes when I am driving the 600 and it kicks down perfectly
the acceleration feels like my old CL65.
However doing the quarters doesn't involve kickdown.
Each time I used sport mode and selected 1st gear. I also tried with and without traction and 13.6 was the best I could get, but as I said I think my box is a tad slow, with the upgrade on my 63 it should do better than 12.7,
I was expecting around 12.3 slightly quicker than the stock 12.5.
I am now looking into buying a new box, so if anybody has some recommendations I would love them.

I presume i/c pump is intercooler pump, if it is I will get it checked.
By the way, on these dragtimes, are they done with things like a/c off and
traction off?

TMC M5

I was using magazine times because I thought he had a GPS based data logger. As stated in my previous posts, a GPS based trap speed will be higher than a drag strip trap speed because the drag strip averages the last 66 ft of the run. I ran a number of times at the track while simultaneously running my Race Logic pbox. The pbox trap speed was up to 2+mph higher than the track trap speed. So yes, a stock M5 is capable of running a GPS trap of 118mph...which should translate into around 115-116mph on a drag strip.

Tom

Good info, I was just amazed & recorded info here due to nearly everybody always states M5's Trap 118+ on 1/4 mile in stk form, as you obviously know this is far from truth in real world

sound 8

My question remains unanswered, when doing drag times do you switch
every thing off i.e. a/c/ traction/ anything that drags power from the engine.

TMC M5

If I am running drag radials on my car, I will put the car into dyno mode. So there are no electronic safeties on (i.e. ESP). On my stock tire runs I leave ESP on. I don't think any of the runs have been with A/C on.

Tom

sound 8

Thanks for the answer, I realize that to get a good time then all accessories
should be off to get the best time.
But surely this will not represent times you would get on a every day drive
with a/c and all switched on.
Also can you recommend a good box, a stand alone box, not for plugging in to
laptops etc.

TMC M5

Um... the times with my stock tires do represent times I would get out on an every day drive. In fact I have achieved better 60-130mph times away from the track by .25s. I usually turn off the A/C if I want to do a blast down the highway... it really isn't that difficult to hit the "off" button on the fly. I told you that I left the ESP on at launch for my stock tire runs...

A "good box"? Do you mean a data logger? The Race Logic performancebox has a display screen so you can see all the numbers as you make the runs. You can also insert a memory card to download the data and analyze on your computer at a later time.

True, iirc they're a 116-117 car....but as Tom said their hotzone is from 100-150 and above where a 55kompressor of 63 will be left...

car is looking exclent now it's finished btw, great job

i agree with this comment. my SL 63 is 4 months old. the more i drive it, the more i love it!! i did not get the car for racing. it is my summer daily driver!!

sound 8

I said nearer to a 65, not as fast!
On my test strip my CL65 done 135 mph, the 63 used to do 124, now it does
130 after the upgrade, that's nearer!

sound 8

What do you mean " where a 55kompressor of 63 will be left..."
no kompressor on a 63!

AMGfan

Meaning stock for stock an M5/M6 will have "longer legs" or will be faster in the top end of the speedometer (120 and above) than a 55K and a 63 (less so with a 63).

sound 8

I still don't understand the ..........of the 63...... it sounds like he is implying
the 63 has a kompressor.Or is it a spelling mistake.:
I would have thought with 7 speeds the 63 should pull well up to 150.

AMGfan

Attribute it to misspelling...stock 55k are notoriously known for pulling hard on M5/M6 up to 100-120 after which the M5/M6's start to catch up and pass the 55K.

The 63's on the other hand are supposed to have closed the gap or equalled (no first hand knowledge of this) the high speed dominance of the M5/M6...
