300 SEL 6.3 U.S.-Version was created by Sven450SE
Moin,

kurze Frage zum 300 SEL 6.3 U.S.-Version: Wurde da auch am Motor rumgepfuscht (niedrigere Verdichtung usw.) wie beim 450 SEL 6.9?
Ich konnte im Weltnetz dazu nichts finden.

Gruß,
Sven

Hallo Sven,

soweit ich weiß, hatten die 6,3er und 6,9er immer die
volle Leistung.
Nur der 4,5er weniger.
Liebe Grüße

Schorsch

Hallo Schorsch,

nein, der 6.9er war definitiv von Anfang an auf 250 PS getrimmt für USA-Export.
Für den 6.3er habe ich doch noch folgendes gefunden:
forum.mercedesclub.de/index.php?thread/1...lben-m100-6-3-liter/
D.h. 1971 auch der definitiv heruntergetrimmt. Stellt sich mir nur die Frage: ab welchem Baujahr? Sind die Modelle bis 1969 wenigstens noch unverpfuscht?

Gruß,
Sven

Hallo Sven,

lt I-net waren die 6,3er immer 9,0 verdichtet und mit 250PS
Erst der 6,9er im W116 wurde niederverdichtet.
Liebe Grüße

Ich glaube nicht, daß der Kollege BerndBauer vom Mercedesclub Unsinn erzählt. Warum sollte er das tun?

Nein, natürlich glaube ich das auch nicht, Sven.

de.wikipedia.org/wiki/Mercedes-Benz_M_100

Aber auch im W108/W109-Buch steht davon nichts.

...im letzten USA Modelljahr 1972 wurde der M 100 niederverdichtet und mit Transistorzündung ausgerüstet !

Sicher? Hast du da eine Quelle für? Das würde der Angabe von BerndBauer widersprechen, der seinen 6.3er als Bj. '71 angibt.

...sehr sicher, gehört zu meinem Beruf so etwas zu wissen !  Baujahr 1971 kann durchaus USA-Modelljahr 1972 sein !

Quellen  : Einführungsschrift Modelljahr 1972 USA, Tabellenbuch Personenwagen 1972 !

Es gibt allerdings nur sehr wenige Fahrzeuge dieser Ausführung, da der 6,3 kurz nach dem Modelljahrwechsel aus dem USA Liefer-Programm  genommen wurde !

D.h. bei einem Bj. '69 wäre ich auf der "sehr sicheren" Seite. :-)

The US 6,3 has 8:1 compression. The Euro is 9:1.
Mercedes has to my knowledge never stated any difference in power on the two different engines. But they are different and feel different. Mine is fitted with a euro engine.

All new pistons sold now by Mercedes for this engine however is 8:1

Even a 1969 model? What makes you sure of that?

To really find out what was going on, you would have to know the detailed emission parameters of the engine and the exact laws at that time.  See for example:
en.wikipedia.org/wiki/Clean_Air_Act_(United_States)
www.law.cornell.edu/uscode/text/42/7521#tab_default_2
www.federalregister.gov/
Then you could check if the engine met the parameters of the current act. But this seems to be really complicated, you need to be a lawyer for that.

Sorry. My bad. I was a bit quick there. Pre 69 are of course 9:1.
9:1 engines for 109 are supposed to have motor.-no 100981 according to Wörle Fahrzeugtechnik. US are 982 I think.

...that´s all wrong, too ! All 6,3 Europe or USA engines are 100.981 only the optional low ratio version is 100.982 ! The 100.983 is the low ratio version of the 600 engine !

And there is no 8:0 ratio for the USA 6,3 engine before model year 1972 !

It makes sense that the "8:1 M100" wasn't introduced before 1971 (MY 1972) because according to Wikipedia this was also the year when the lower compressed 300 SEL 4.5 was introduced:
en.wikipedia.org/wiki/Mercedes-Benz_W108/W109
The table is a bit misleading, but as far as I understand it, the unmodified "3.5" was sold in the U.S. until 5/'71 and then replaced by the "4.5".
