SL55 AMG, M5 E60, 2002 S55 AMG, Range Rover Sport Supercharged,
Regards and concerns of the SL55 AMG's performance statistics.
Good afternoon to you all. Just wanted to ask some curious questions and put my thoughts.
I already know that a 2003,04, 05, and 06 SL55 AMG has 493 Horsepower at 516lb ft torque. Performance stats show that times to 60 mph comes in from 4.5 seconds to 4.7 seconds. I've seen as a low as 4.3 even.
And to 100 mph, I've seen stats showing from 9.8 to 10.9 seconds. Even as low as 9.5 And now, for the quarter mile, varying times from 13 seconds at 110 mph by Car and Driver to 12.5 seconds at 116 mph were claimed.
So now, my question is, how really that fast is the SL55 AMG? Because coming in at 13 seconds and 110 mph for the 1/4 mile to me for a SL55 AMG is not really that fast... I mean the BMW M5 and M6 trap 115 to 118mph at 12.4 seconds.
I've searched the internet and I've seen varying "slow" times for acceleration and quarter mile. So now comes to this, is it a bad IC Pump or intercooler pump? Shut down supercharger without knowing it?
I know the SL55 AMG with 493 HP and let alone the massive 516 lb ft torque has more than enough power to catch up if not beat the M5 and maybe even the M6. Potential and will is what AMGs really have.
So now, I'll stop my mindless pointless text to ask you, what's the fastest times for acceleration and Quarter mile for the 493 HP engine and your opinions and thoughts on what is the average or expected times of acceleration and quarter mile times? I have yet to test this out want to ask you fellow SL55 AMG owners.
Thanks and regards.

The best reported time on Dragtimes is 12.5 with a 116 trap speed. http://www.dragtimes.com/Mercedes-Be...ag-Racing.html
So best case is probably 12.4 to 12.5 seconds with a trap speed in the 116 MPH range.
You can lose a couple of tenths to heat and humidity. You can also lose a couple of tenths or even more due to track prep. So it's possible for your car to be running fine and still post times near 13.0. Of course similar cars would be posting similar times at the same track on the same day.
The intercooler pump can fail. I have a modified SL55 that I figure should run low 12s on a good day with trap speeds north of 116. My best time was 12.59 with a 111 MPH trap. I took it to the dealer and suggested the pump was a problem. They couldn't identify the pump as a problem and declined to replace it.
The next time out to the track I had an AutoEnginuity logger attached to record the Intake Air Temperature (IAT). It measured 205 F at the start of the run and 266 F at the end. I clocked a 13.29 for that run. Since I was able to provide proof that the IATs were out of spec the dealer replaced the pump. I haven't had time to get back to the track, though.
Good luck getting to the bottom of the issue!

The M6 ran 12.4 seconds in the Quarter at 118 mph according to either Road and Track or Motortrend I believe.
Well. Since your stock SL AMG ran 12.4 sec, then your car is healthy and working properly like the way it's supposed to. Still, other cars can have problems with their supercharge or pump.
If you can recall, when you ran 12.4 sec, what was your mph trap speed? Around 116?

Now... What does it run now that the pump has been replaced!?
Get to the track please! Lol!

Yes. I too, would like to know the new differences of trap speed between bad ICU or intercooler pumps and a new installed one in the quarter mile.
But you say your SL is modified? What mods do you have? I have a 100% bone stock SL55.

You are going to have a really hard time getting this data to line up to draw these types of conclusions.
Too many variables in play here unless you have two cars on the same track running side by side.

I think there are too many variables to draw very specific conclusions from my next 1/4 mile run. E.g. even though my pump was no longer running to spec, it still generated some cooling and reduced the IAT from 265 F to 190F after the 1/4 mile run. Other pumps may be in different stages of failure.
But I will share the results whenever I'm able to get out to a dry track.

The Friday forecast is mid-70s and sunny with humidity around 40%! The Milan Dragway track prep is usually pretty good, too. Maybe you should drive up from FL and see if you can break into the 11s!

I think the variables that you are seeing are from drivers and climate conditions. I know that my car is VERY susceptable to hot temps. In the AZ summer, the car usually feels dead, but we had an overcast morning with temps around 80, and all the horses were back in the barn.
I know that I chase down GT3's and hang with Z06s at the track. If you think that's not fast enough for you, I'll take you for a ride! .....and give some religion!

And that is an issue, with the driver and how the weather is. Don't forget the I/C Pump can easily fail causing the supercharger to shut down...
That and it's pretty impressive that your SL can beat down GT3s and hang with Z06s especially at the track!
But wait! Your SL AMG isn't stock, 550 hp and torque?

It has 550lb ft of torque as well. Its nice to keep the numbers even!
I see that you are in Englewood Cliffs.....home of FNA. Back about 100 years ago, I was one of the tennis pros at the Tenefly Racquet Club.

Do you know Jeff? He's an instructor there at the club, and do remember the lady who can read lips (usually an ability for deaf people)?

...
honestly who cares about the exact performance stats....its not a track car, and as far as driving on the street goes, no stock car that you would normally run into should ever beat you...i have a friend with a gallardo spider, hes good w/ the the e-gear bc he had a gallardo coupe before but his gallardo doesnt blow me out of the water or anything, the sl55 is an incredible machine

IATs were still a bit high even after the pump replacement, peaking at 172 F.
It looks like the ECU may have backed off on the timing (from -16 to -13) as the IATs climbed. If one of the heavy-duty tech guys could comment on that, I'd be grateful.

I ran 12.39 seconds (not bad) with a 110 MPH trap speed (disappointing).

Was the car idle-ling along time in the staging lanes?, where you aggressive in the burn-out box?. Your starting iat's indicate heat soak before the run, a 30+ degree change in iat's through the 1/4 mile under boost is not bad for a stock ic system. The initial iat of 130 + is to high to start off with, unless the car is being hot lapped. imho.

I drove to the track then hot lapped all but one run. My fastest run was the third of the day. The run that I did after taking time for cooling down was actually one of the slower runs.
Burn-out was mild...1-2 seconds or so.
What I probably need to do is wait for an even cooler day, then get to the track early and let the car cool completely.
I hear you! I'm thinking I should be north of 115 MPH but it's just not there for me.

But wait. I hear you have mods on your SL?
All I can think...is...get your intercooler pump changed again?

The Johnson pumps are pretty affordable but I'm going to wait for cooler weather before trying anything else. I drove to the track, then hot lapped on a 77 F day which was less than optimal as several folks pointed out.
