• Mercedes AMG twin turbo V12 changes - How the new M279 Twin Turbo V12 differs from the previous M275

      You should all know by now that Mercedes is bringing back the twin turbo V12 with the new R231 SL65 AMG. We originally thought this was just the same old M275 V12 that had seen duty in the previous generation 600 and 65 AMG's but the motor has received some updates along with a new M279 engine designation. The 6.0 liter V12 to reach its new 630 horsepower rating received far more than just different ECU software.


      A multi-spark ignition with twelve double ignition coils is used that Mercedes states provides for a smoother motor and more effective combustion. This also is used in conjunction with a new engine management system.

      The cylinder heads were also revised in order to flow better for more power. The turbos have been changed featuring new wheels and are mated to new manifolds. The wastegate ducts have also been revised.

      Additionally, the exhaust system underwent some significant changes. The catalytic converter system was optimized both for emissions and power. The wall thickness of the exhaust was reduced and the system is now 7 pounds lighter than the previous generation.

      Other parts such as the intercooler, throttle body, and airbox remain the same. The M279 is a nice update to what already was a stout powerplant.

        What do you say @Jacob502 ?? I've PM'd you and done as you asked to "contact you" but you haven't responded. Maybe you can man up and agree to the aforementioned bet since you are so sure of yourself.
        I pmed you pussy. Now call me !

        Called you three times - forwarded to voice mail each time. Figures....

        You didn't answer my question above. Since you will not agree to any of the terms of a bet for money, I suggested we just bet and the loser never posts here again. So that's like my 4th suggestion for the bet YOU started...why won't you agree to it ?? C'mon man, do you realize what a coward you look like here ?? Everyone is laughing at you....I've done everything you have asked, even called you yet you won't even pick up the phone after telling me to call you. Why are you so scared ??

        So, once again you are the only LIAR here. You've run out of excuses and I think it's pretty clear that everyone here can see you for a true gutless coward hiding being his keyboard.

        Yeah sorry my bad, I only called twice LOL. Like that $#@!ing matters ??? You said I didn't call you....I just showed you evidence that I DID. So now are you saying that since the rest of the number isn't showing that I made up the number or something ??? REALLY ?? Ok then, if you want to play it like that, here is YOUR private message to me so everyone can see that I did in fact call you - and just for the sake of privacy I will use X's in the place of the last two digits just like my blackberry did:

        All right $#@!

        Call me +974-302222XX
        Now, I really think you need to shut your $#@!ing mouth and quit making excuses. You are the biggest joke I've ever seen. And I'm just going to warn you ONE TIME. If you come back here and say I made that number up and edited the private message, I will take a SCREEN SHOT of the private message that CANNOT be edited and I will post that with your full telephone number for everyone to see.

        Yikes.

        Pretty hard evidence that no less than 2 calls were placed to Jacob. I don't know you Jacob, but are you still insinuating that LZH did not call? The truncation is just something phones do in their logs. No reason to think that LZH actually dialed "..." for the last few digits.

        Come on now, at least admit that he called, and you didn't pick up. Twice.

        LOL - exactly. He won't admit anything and I think it's clear what type of person he is.

        Tried to rep ya, "You must spread reputation around before rating this user again"

        He didnt call me and I did not recieve any call from him. Its obvious he just took my phone number to just to expose it to everybody here just like he threatened.

        The screen just shows a forwarding dial made at the same time. Anybody could do that and take a still photo without actually making a phone call.

        I already told him to give me his number and he didnt!

        Now here is a threat to LZH. If you throw out my number. I will take legal action against you!
        Be careful what you post!

        I didn't "expose your phone number". The last 2 digits are missing. Despite what a loser you are, I wouldn't do that. And that is the reason why I don't send you MY number because I'm fairly certain you would not extended me the same courtesy.

        What are you talking about a "forwarding dial" ??? That is a screen shot of my CALL HISTORY. It says it plain as day. It shows I made 2 outgoing to calls to you...and you didn't pick up. You've made every excuse in the book Jacob and everyone now knows what a true coward you really are. Did you ever think THAT is the reason you have been getting neg repped ??

        And now you threaten me with legal action ?????? HAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!Click here to enlarge
        Man, every time I think you have gone and done the stupidest thing possible you surprise me with something even more idiotic that the last. And for the record since you can't read....I said the following:

        You haven't done that....yet. But if you do I will post your full number and you can "take legal action". LOL. Last time I checked it's not illegal to post someone's number online - ESPECIALLY WHEN YOU GAVE IT TO ME!!!!!!!Click here to enlarge

        One last thing - I don't make threats; I make promises. And if you don't believe me, keep making bull$#@! excuses and you will find out the hard way.

        Relax, I won't be allowing your personal information to get spread like that.

        However, I think you guys should come to a resolution and the sooner the better. Dispute resolution section may be a good idea...
