    • 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.

        No offense to you or him, but I don't know any of you to be wiring any funds. I want this to be official and notarized through a bank. LZH is a typical liar and is trying to run and hide and tries to throw insults to get away from the real matter. That's very pathetic. If I lose, I will be more than happy to wire him the funds directly to his account. However, if he lost (and he will) I want to make sure he pays up, which I am sure he wouldnt.


        Its up to him, he can contact me anytime. I am in Chicago. Now let him man up and speak with me.

        While I can appreciate you being apprehensive with your money, and understand it. I have NEVER known LZH to be a dead beat. Why not let Sticky hold it? After all, he would have MUCH more to loose than 20K, IMHO.

        Just a thought.

        While I can understand how you are hesitant to send money to someone you don't know at all, I'm also pretty sure this is just another one of your diversionary tactics which is being employed simply because you either know you are wrong and don't want to lose $10k, or you are not man enough to stand behind your word. I'd say it's probably a combination of the two. I've suggested a few alternatives to make this happen yet you are unwilling to agree to anything.

        So your suggestion is to have a bank handle a bet?? LOLOL!!!! How do you propose doing that ? Open an escrow with a mutually agreed upon financial institution? What will be the terms of the escrow ? Do you plan on telling the escrow officer it's for a bet ? And who determines the term (16,18 months?) and conditions of the escrow ? See, these are the details that will have to be addressed if we do it your way and there's a lot of wiggle room - and for someone who is already wiggling I really don't see the need to give you another inch.

        I do however have a very good friend who owns Wilshire Escrow which one of the best and oldest escrow companies in Los Angeles and I have used them many times. I'm sure he could accommodate our little transaction with very little fuss. But, since this is your idea, and since you are the one who made the bet in the first place, I think it would only be fair that you pay up front all escrow fees that would be incurred (notary fees, sub-escrow fees, closing costs, etc). However, I also think it's fair that the loser pays for these fees. So, if I lose, I promise to reimburse you for the fees plus interest.

        I think this is a pretty fair compromise especially considering I'm the one doing all the compromising - So what do you say Mr. Big Baller ? I can get the process started immediately.

        And just for the record, here is the official bet:

        You say the SLS BS, if and when it's released, will have a the M279. You said nothing about NA or FI. I said that it will not have a V12.

        Agreed ??

        No problem guys. I understand the apprehension on Jacob's part. While 10K isn't really a LOT of money, it's certainly enough to be hesitant to have an unknown escrow. Jacob, you don't know me, but MANY on this board and MBWorld do. Matter of fact, lots know my home address, my place of business, and have met my wife and kids. While there are certainly many people on the interwebz that tend to lie, cheat and steal, I would venture a guess that any one of the people that I've mentioned, would more than vouch for my integrity.

        Ok, that said....

        I think LZH has made a very good counteroffer of having Wilshire escrow the funds. They are as legit as you're going to get for a bet such as this. Carry on gents....

        thanks for the vote of confidence. since the bet originated here and Sticky started this thread, that's why I initially suggested he act as an intermediary but I guess Jacob wasn't comfortable with that either...I actually thought that was a good idea and would be willing to donate the accrued interest to Germanboost as a show of appreciation - hell, I'd be willing to give all my winnings to Germanboost. I think that is what should really happen but am willing to compromise to make sure Jacob mans up - but I'm sure he will come back with insults of some sort and an outlandish suggestion of how he wants this to take place with lots of the aforementioned wiggle room for him.

        But that's ok and I'm prepared for it - I think we can all see what's going on here. But I do have one last proposal should he back out of my most recent offer....a proposal that if he does reject will make him the biggest coward around. tick tock, tick tock...

        Hey moron,

        Why dont you stop being a pussy already and contact me?. Obvioulsy your trying to get people involved in this as you are to much of a coward to deal one-to-one with me. Now I already told you, we will do this deal through a notarised esatblishment. Like I said, I have done it before. Your asking how? DUDE JUST CONTACT, I DONT BITE..loool

        now listen, you can keep trolling and talk 5hit all you want. Seems like the best thing you could do in your life. Unless you grow some balls and be a man to contact me, then just shut up already.

        I will not wire any fund to anybody but you when I lose and I want to make sure that you pay up when you do!

        I'm done with this thread. You wanna bet? contact me and stop being a child.

        Never heard of them. I dont intend to deal with them.

        Just as I suspected. I've proposed THREE different ways to handle this bet and each time you've made excuses and evaded being a man and standing behind your words. Sounds to me like little Jacob is a scaaaared little pussy LOL. Yet all you have to say for yourself is that you want me to "contact you". Why ?? I don't understand - can you please explain for me and everyone else what calling you on the phone will accomplish ? What do you want to tell me that you can't say here ??? If you want me to call you, please send my your number via private message and I will call you RIGHT NOW. I'm not giving you my number because I know you will add it to every tele-marketer database you can find. I'm that stupid. But I can guarantee you this - send me your number and I will call you. Once we speak, I will delete your number and never use it again for any purpose.
        Does that sound good ? I'm doing everything you ask...yet slowly but surely you are running out of excuses and places to hide except behind your keyboard.

        Oh yeah one more thing....You should really tone down the threats of violence online. I'm sure the US State Department would find it interesting that a foreign national from the Middle East is making threats of violence against Americans online while he is in the USA.

        Waiting for you to PM me your phone number. And don't worry about international rates, I have Vonage LOL.

        No he doesn't. Money isn't the problem here for either of you guys.

        Just stop arguing with each other, it's stupid and makes the whole forum look bad.

        Look, I think this is not getting an M279 and likely going to get a tweaked M159 as reports have been thus far. Even if the M279 physically fits it just doesn't match the character a Black Series based on the SLS would be going for as well.

        Additionally, look at this precedent. The Black Series has always used a motor already available in the chassis.

        If necessary I am more than willing to support this man's credibility but I don't think this is happening.

        It's time for parties to concede.

        If you really want to do this there are several options already suggested.

        None of which he is willing to accept, much to my chagrin.
        I think I've done all I can do to make this happen. I guess at this point it's just going to be a "gentlemans bet" and I use that term loosely. I had another proposal I was going to suggest but I'll table it until we hear from Jacob again or perhaps he will send me his number and we can discuss privately.

        Since it's clear that Jacob isn't going to honor his word. I'd rather we both agree to another bet....if he loses he agrees never to post here again and his account shows as "BANNED". If I lose, I agree to the same.

        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.
