Build the most powerful cls550 4matic
The Best of Mercedes & AMG
I have successfully installed the Aquamist HFS4 water/meth injection as well as two oil coolers on both left and right side of the front bumper. The Meth is the best upgrade power/cost that i have installed. The timing is advanced as much as possible, no knocking and the power is close to 800hp crank. Will dyno the car next year. Just for information 100-200 is about ~6 sec. Compared to my CLS63 amg PP that is 700 hp it's ~ 6.8 sec

Thats unbelievable...
Would you share the parts you bought and have done ?
But are you able to help out for the ECU tuning if its shipped to you ?
(there was no info as this is the first build m278) Here are some pictures of my cooling setup including the two oil coolers at the front and the Meth in the trunk (pictures taken while installation in progress).
The bottom line: I have invested ~17-20k USD in the build. If i build it again will go under 13-14k as some parts are not required (same as the m278 engine). The most expensive are the M157 turbochargers that you can get as low as 4-5k second hand (they need to be less than 30k miles) and new up to 10k, ECU tuning about 2-3k (few sessions included), intercooler system upgrade 1.5k, Aquamist hfs4 1k, oil cooler upgrade (not needed if your engine is equiped with oil cooler from the factory) 1k including the oil lines and AN10 hoses and AN10 fittings, Exhaust system, full dual 3 inch from the turbochargers to the mufflers 4-7k. Turbo-back downpipes are required (for example my cls63 fell off a cliff after 5.8k rpm -100hp till redline due to restricted flow of the stock turbo-back downpipes), Quaife LSD 1.5k, AMG front and back brakes (required!!) 3k. Labor for engine removal (turbocharges installation) 380 USD here in Bulgaria LOL.. All other installations except the ECU tune are performed by me
including the build of the exhaust, downpipes (including 3d printing and 3d design), meth installation, cooler installations etc..Overall i preffer this car over any rear wheel drive 700hp+ AMG
Will check for the ECU tune and will let you know.

Is it the Qualife AMG LSD you installed ?
And what year is this CLS550 ?

You can install LSD on 4matic with zero problems with traction control. The car is much more stable and predictable. Also you put all the power to the ground.
This car is 2013 EU version with all possible options included. Including carbon fiber trim same as cls63 amg that was optional when ordering the car (i think it's not available in any other 550 series)
Happy New Year!!

wow...2.9 sec 0-100km/h
That is insane.
I have got a pair of M157 Turbo here, waiting to be installed.
If mine has oil cooler already.
I should be able to just bolt on these turbos on my M278 engine.
I will also need new gasket and copper nuts.
Is that correct ?
Who tuned your ECU ?
Would I be able to jsut have the same file into my ECU to get close result ?

He told me, it achieved 600WHP.
Is yours WHP ? or to the crank ?
Yea, same here...bad weather....snowing like non-stop.
Btw, would you be able to share what is the part (model) number for the Quaife LSD ??
Thank you.
Thank you bro!!!!
And I guess I have to go with E500 model ? (because I have got E550 4matic)
I found this
http://www.birdsauto.com/parts/21233218360
And, I am wondering,
Is it a big difference ? just upgrade to this Quaife DIFF ??
