• Renntech tuned W221 S550 4matic M278 turbo V8 takes on a supercharged built motor Camaro SS in the 1/4 mile

      The M278 4.6 liter twin turbo V8 may not get quite as much attention as its 63 AMG M157 big brother but it is a plenty potent motor. It shows here with a Renntech tune only S550 on street tires managing a 12.4@112 in 90 degree Florida heat. The Camaro runs a 11.8@122 which is not all that impressive for a built motor 6.8 liter LS3 with 4.10 gears and a supercharger. The heat definitely affects both cars but it goes to show how quick the S550 can be with a tune.

      In better weather with negative DA the car would likely be capable of high 11's. Not bad for a tune only all wheel drive S-Class which would make a potent sleeper.

        I'm hoping we will see upgraded turbos for the M278's.

        Days ago i lined up with a newer CLS550 which had Brabus tune and exhaust at light. The light went green and we set off. I had one of the best launches with almost zero wheelspin and shifted pretty well, on the other hand the other car was spinning tires all the way. I was 4-5 cars ahead at 80kph and then the CLS got a hold on itself and pulled on me like Shinkansen train with a great soundtrack.
        Very impressed with what these engines can do with a tune and exhaust.

        I don't to be honest. The car had Brabus badge on it and when i asked the guy what he had in, he said tune and exhaust. I assumed it the tune was done by Brabus.

        I think I should probably move these to OT.

        Sorry to hear man. They will just let you live in France just like that? I would think immigration into France would be tough right now especially for Iranians.

        Move them or delete them so as this one. Sorry for drilling the thread.

        Thanks. No of course they don't me live here just like this. I've been coming here for months to do the interviews, backround checks and doing paperworks, plus i lived here when i was studying for 5 years plus and keep in mind i'm investing money in this country. When it comes to money, they become great hosts all of a sudden.

        I was looking at the 12.4 et that this S550 (bi-turbo 4.7) ran at PBIR. Is it fair to compare to the C63 that ran on the same strip and managed a 12.8 (at night)? I know there are a lot of variables so please don't flame me. What et would a stock S550 (4.7) run?

        AMS Archetype tuned Mercedes CLS63 AMG M157 Twin Turbo races a C63 AMG, Mustang GT500, and Nissan GTR in the 1/4 mile The strip is PBIR (Palm Beach International Raceway) in Florida and the summer heat has a big influence on the times with the stock C63 managing only a 12.8@109.

        I think it's a valid comparison.
