we had a little room and i would say we were doing 25 from a roll and I hooked up my traction and took him by 2 car lengths to 100.
not really close

 

As expected.
Nice kill.

 

Whats the HP and TQ disparity? I would expect you to pull him that much.

 

I plan to order a CL63 with performance package, but am torn with getting the CL600 instead. I lean toward the biturbo rather than a normally aspirated engine. Any opinions are welcome.

 

Have a 55 modded and a 65- go with the 600 and do a simple chip mod.

 

Get your ECU and TCU done by Renntech and expand that lead to 5 lengths to 100. The 600 with the Renntech ECU/TCU is a completely different car.

 

the 600 is a no brainer. the 63 engine is just dumb in an s or CL class,
if you ask me!

 

I know my dad did it to his 600sl in FL. it is soooooo fast!

 

owned....lol

 

I thought the 65 is the bi turbo and a AMG and the 600 is non turbo?
The 63 is AMG and NA engine. The 600 is optioned more than the 63.

Dealers say that CL65's (V12 Bi Turbo) are due out sometime in 08.

 

65 is twin turbo ... so is the 600.

 

A Rennteched out CL600 could possibly put out a good bit more than 800 lb/ft of torque. There is a member on this board with an SL600 that is Rennteched, and he has 911 lb/ft of torque!! Even 800 lb/ft is just way beyond the power level of the CL 63's 465 lb/ft. Even if you add a Renntech ECU, Headers, and race exhaust to a 63 V-8 you will have 550 to 560 horsepower and maybe little over 500 lb/ft of torque. The Renntech ECU CL 600 will still win hands down. Get the CL 600, add the CL 63's bodykit/wheels/brakes, Renntech ECU, and say good night.

 

Look here for CL600

.......don't worry, although he lost he has three valves per cylinder. Aren't you jealous?

..........ever wondered why there is no NA SL63? If the 63 engine in its current form is so wonderful, why is Mercedes/AMG continuing with the SL55 instead of introducing the NA SL63? Something to think about.

Ted

 

Did you mean "even though he lost he has four valves per cylinder"?

 

Ted, I think you'll be seeing the NA SL63 sooner than you think.

 

.......you may be right. If you have info, kindly share it.

......my brain tells me that it is too late now for a NA SL63. They obviously made a conscious decision not to introduce it in 06 or 07. The reason is obvious to me, but you may dissagree. Be that as it may, the Sl is scheduled for a re-design soon. I doubt they will introduce a NA SL63 right before the re-design of the SL. I think they learned their lessons with the W220 S65 and W215 Cl65. Maybe you know something I don't.

Ted

 

..........yep. so much for that joke. I feel like John Kerry

By the 2010 model SL, MB will probably have the TT 6.3 V-8 Ready anyways. The V-12's will probably be upgraded to the new 4-Valve DOHC design, and the 65 V-12 engine also.

 

It is funny to think that, despite being the "lowest" in potency compared to the 600 and 65, the 63 engine is the largest one, by .2L with the 6.0L V12 in x65.

Adding turbochargers would be nice, but would definitely cause further confusion as to the hierarchy within the range. the tt V8 would be very close to the current AMG v12 in terms of power and torque--the next V12 would have to do so much better... or differentiate through another route.

My father in law who owns a large MB dealership among other brands told me that, the reason they made the 63 engine was because some german green laws were cracking down on supercharging. But the SL body style was old enough to "grandfather" it in until the model cycle is over.
the 55 would kick the doors off the 63 in an SL

 

That explanation makes no sense considering the W211 E-Class was released around the same time and same model year. The proper explanation I've heard is that the Kompressor engine is too tall to meet pedestrian safetely laws, as there needs to be adequate clearance for the hood to absorb impact, which is accomplished by removing the S/C. The SL probably has sufficient clearance to comply, but the E-Class did not, which is why we have the E63. As for the 63 engine in the S and Cl classes, they just want to introduce the new technology. There's yet to be an instrumented 3rd party test, so it's still too early to confirm how much of a power deficit there truly is between the two.
One important thing people are overlooking is that the 63s have a higher redline than the V12's. While the torque may not be there, it is compensated for higher in the rev range.

 

[QUOTE=jimand7;2249311]
LOL.. Your 600 argument makes complete sense.
The 55 in any model stock is not "kicking the doors off" a 63. Stock cars are so close it is a truly amazing race. A stock 55 and stock 63 E class ran many many passes and the car getting the better light won everytime. Who ever had the initial advantage held it. I backed off of comparing the 63 engine to the 600 because while the 6.3 is larger it is truly unfair to compare it to a V-12. Would you compare the 63 engine with the 500 or even the 550? N/A motors? I

 

Why? There's no inherent performance advantage to a V-12 over a V-8; the opposite is more the case. More moving parts mean more frictional losses and more weight. The point of a V-12 is smoothness for the same displacement.

The real difference between either the 600 or 65 engine and the 63 is forced induction. So when comparing the output of the various engines it makes no sense to leave the V-12s out because they're V-12s. The bottom line is that they produce more and way more torque and power compared with the N/A 63 engine, despite its theoretical design advantages. Detroit gets 600 HP out of pushrods. So what? These engines should all be compared on the basis of their driving characteristics. The twin-turbo V-12s are the strongest, most driveable engines that MB makes. Their main disadvantage is weight, which affects handling.
