SL600 V12TT

Would this be a close race?

jturkel

to start with, yes. SL600 would have major traction issues from a dig and the E55 isnt exactly slow. But as time progresses and the race goes on, the TTV12 will pull away (by how much, idk). This is obviously assuming everyone is stock and we are talking about the W211 E55 and newer body style SL600

I raced a Stage 2 RennTECH before in my SL600 and we were door to door till about 120. I had the convertible down.

Stock to stock, the SL600 should pull from an E55. I know my 600 spanked my SL55.

600 will pull away if E is stock....otherwise neck and neck. The SL is very heavey as well.

Vic55

Agree with all assessments; modded vs modded the SL will pull as well unless--- the E is stage 5.

Are you talking about the normally aspirated SL600? or the Twin Turbo SL65? or a turbo version of the SL600? I am not sure which car is in question.

I drove a 1998 SL600 which does not have the turbochargers. It was quick and smooth but my old C36 would spank it and a E55 was spank it hard. Now a SL65 or even a later turbo model of the SL600 would be another story. Your question asked if the SL600 could keep up with the E55 AMG? I guess the answer depends on which model we compare to and if the E55 owner has a pulley system? lol

Turbo cars are very fast and can potentially be real killers. The OP's siggy has TT at the end so, I would assume that his SL is one of the newer twin turbo models (2004 right?). If so, then he has a good chance vs the E55. The 5th gen SL's (2003 to 2008) have about 500 hp in the V12 model and are pretty quick. Just beware, the AMG horses are larger than regular MB ponies. AMG only uses big Bavarian steroid eating monsters, with large hairy hoves which shake the ground when they walk. They have large stainless steel and titainium balz that strike sparks when they drag the pavement, and they bite when you get too close, lol They can be formidible opponents

^^ Irish, he "Drives: 2004 SL600"... which is the twin turbo'd model.

I stumbled into a chance highway run with one of our forum members a few years ago. His CL600 with ECU tune vs. my stock E55 from roughly a 70 MPH roll. He ran away from me very easily. Stock 600 should walk a stock 55, with it getting uglier as the speeds climb.

I looked into the SL600 vs SL55 some time back on the SL forum, and what I found was this:
To me they're quite close, given that the SL55 is a bit heavier and thus the E55 should be a tad bit quicker than the SL55....I'd also think the E55's better Cd (if memory serves me, it's got a better one anyway! ) and lower gearing would help to mitigate the V12's torque advantage up high.

But hey, you can always chip that TT V12 and you won't have too many worries about that sort of thing!

TMC M5

I thought the gearing was the same in both cars?

Oh, is it? I was going by memory, hold up, it was a Car & Driver article I think....yeah, found it:
Although, now that I think about it, this may not be correct...OK, more checking...geez louise, has anyone else here had the urge to track down the folks who designed mbusa's "new, improved" website and administer a severe beating???....OK, can't find it there anymore; anyone know where to find it??

Improviz, remember cD does not tell the whole aerodynamic story. It's more of a marketing figure. If you were being sarcastic about the aeros then please ignore this post.

Akademiks

Improviz... I see all your stats, and going by experience, I have to say the mag is full of ***** or they didn't properly test the two. When I was debating which SL to let go of, I ran both of them numerous times under different circumstances with different drivers, and the 600 always came out on top. Had the 55 been faster, I would of ended up keeping the AMG. I don't know, maybe my 600 just won so I can come on here and disagree with you and get pwn'd again

Improviz

Actually, if you read what I wrote I said that my numbers put the 600 ahead in the comparison I did...but I haven't run one yet, and so I'm not going to declare one to be the unequivocal winner until I do.

As to the mags: that was actually three different mags, not just one...so I'm kind of doubtful that so many different publications could screw up so mightily in only one car.

Side by side racing is more error-prone than something like a V Box due to reaction time, etc...but if you look at the numbers, you see that up high, the SL600 is a bit faster to xxx speeds, but not hugely so. I ran the numbers in that same thread, and it would pull a car, maybe a bit more above 125 (which is as high as those numbers go, unfortunately, so I couldn't run the numbers to see)....figure if you took it all the way up it'd be out front, but hard to predict how far without some numbers. Still, based on numbers I've seen, it should be a tight race with an edge to the 600, as I already stated.

Akademiks

I really need to go to a dyno... when I raced my SL55, from a 50 roll to 130 I was pulling 4, 5, 6 cars and going...

To clarify, I'm not so much doubting your mags but questioning my results based on the results of those mags...

BlownV8

Yeah, I hear those CL600's are quick.

Improviz

Yeah, I'd do a dyno...sounds like a pretty stout motor. Are you sure she's stock? Maybe she was modded in a previous life

I know that Treynor ran consistent 12.4x @ 114 times in his stock S600, and I recall seeing some guy recently posting a slip of a run he did in a stock S55 which was also a 12.4x at 114, two more snapshots, although without DAs and temp, hard to tell, but anyway I'd think that stock to stock it should be pretty tight...I'd really like to see the Vbox results for some of these cars in 50-xxx runs, or for that matter get in a few runs with one of them someday. One of these days!!

Akademiks

I have no records of it's past life, it's possible though. The only thing I had done was the exhaust delete (yippie! ). My 55 had the same thing plus K&Ns...

Too bad your not local, I'd run the CLS

Improviz

No, not sarcastic...basically the drag force is what really kicks in at higher speeds, and the drag force is determined by the drag coefficient and frontal area...so yeah, it's possible for a car with a certain drag coefficient to have higher force than a car with a lower drag coefficient, provided its frontal area is substantially smaller, but w/the two cars being discussed here, frontal area is probably very similar, so it would definitely play a big role.

Equation for drag force is Fdrag = 0.5CApv^2.

C is drag coefficient
A = frontal area of the car
p = air density, which is about 1.2 kg/m^3 at sea level at normal temps.
v^2 is velocity in m/s times itself

That last part, the v^2, is why the drag force is such a large component at high speeds, and is why if two cars have the same power/weight ratio but one is heavier with more horsepower, it will still pull away at higher speeds (think Elise vs 370Z).

Anyhoo, as I recall the SLs don't have quite as good of a Cd as a 211 E, but I may be mistooken here, going by memory again!!

TMC M5

You are right. The sL55 has a 2.82 final drive and the SL600 has a 2.65.

That is a big deal. Opening up the exhaust on my old turbo car added more power than any other mod. It has alot less effect on the SC'ed or n/a cars. That change alone probably accounted for your SL600 walking on your SL55 AMG. My experience with the V12's was that they had really long legs and once in triple digits they really came into their own. They were set up as autobahn burners and were still loafing at 140+ AMG does not loose face since their SL65 is the car to compare to, lol.

That was sort of what I was saying with my previous post. The turbo cars really respond to even minor mods such as open exhaust and more boost or opening the airboxes to let them breath more. It is pretty easy to get 20% more power without abusing them too much.

Improviz brings a wealth of Mag/drag force/gearing/data to the table, all I can add from an 05' 600's owners point of view is a sh_t load of street races all variables aside (2) encounters come to mind...

Ran JuiceBox 3 bmw 335i, Supercharged LS2 C6 Vette + stock E55 211, & stg 2 e55 211 after calabasas meet last year, long n' short (the stock 211 E55 admitedly had IC failure so omit this race) lost badly to all of us..

The bmw 335i-J3 ran ahead about 2 lengths of the stg 2 E55, then the Supercharged C6 LS2 Vette ran my 05' SL600 dead even door to door from about 30-135mph (2) races the 335i-J3 also lined up w/us but was left for dead....

Fast fwd to following wknd the w211 stg 2 & 335i-J3 & another healthy stock E55 211 met @ same place & re-ran the Supercharged C6 LS2 Vette, ALL were beaten multi-lengths by the Supercharged C6 LS2 (these results are also posted by the w211 E55 members who ran that day in the W211 forum archives 08' late summer time), the W211 stg2 E55 vs 335i J3 were dead even in multi races...MJ50 was the pilot of the sg2 beast

I was runing a mixture of CA 91 10 gallons + 1 32 oz can of Torco as was the bmw 335-J3. The OEM fact recomends 93 oct or better on many AMG & esp V12 TT apps, using 91 tree-hugger oct will give less than optimal performance to say the least (Many tuners ones name starts w/V in CA told me CA 91 is pure garbage & will give sub-par perf on V12 TT) nuff said...

I'll be lining up SOON! w/Max's healthy stock E55 211 (AFE filters only) put down near 12.FLAT @ 118+mph in CA...Should be good

Thericker

I did the same exact mod (only removed mufflers replaced w/3" straight pipes factory CAT's STILL IN PLACE everything else stock, down to crummy oem paper filters) the car def lost a little low-end power but felt a lil' snappier up top.

I had multi-races w/SAME BMW 335i-JuiceBox3 pre-post my exhaust mod results were negligible...ONLY removing Cat's & adding down pipes from the Turbo's will change the HP dramatically, which wasn't done in either case...

HLG600

Sorry friend, but no C36 short of forced induction will even touch it. They trap over 10 mph apart.

Stock? That is a healthy car and some nice driving.
