Does anyone know much about the mod path of the 5.5 s/c MB, i.e. E55 or S55?

 

yes

 

Sure. What do you want to know?


All of these are big name companies that play with the AMG supercharged V8:

what's available with bolt-ons?
how much power can the motors take?
who are the local tuners?
what are the local clubs?
is a start

I think your post addresses a couple

 

Hope that helps.

 

It's a supercharged V8. Yes, there are bolt ons. Like a pulley for example, or headers, catback exhaust, intake, cams, heads, etc etc.

With regard to power, I'm asking about the 5.5 s/c motor not the car. The motor doesn't change very much between the S55 and E55, so any info for one's motor will apply to the other.

Thanks for the info about the clubs/tuners, but I already know of several.

 

It's not that easy.

Then you should have said that.

Then why did you ask? Douchebag.

 

Get a pulley, drop the resonators, and tune the ECU. The engine itself can take a TON of power and abuse.

There is a major problem with these cars and it comes in the form of cooling. When you mod the engine you will create more heat.

1. The intercooling system is inefficient..... No one really has a solution because parts and moding these cars are $$$$$

2. There is a pesky intercooler pump on these cars which IMO is the achelies heal to these cars. When the pump goes out, and it will, the S/C will either disengage or not engage at all. In really hot conditions the pump can not cool enough and for safety reasons the S/C clutch stops working. Some MB drivers have already gone through a couple of these with less than 50K miles. You can get a new MB Bosch pump for $$$ or buy a Johnson pump the Ford Lightning uses which is nearly the same.

If you are looking to mod I would spend little more and by a SL600 or CL600. These have twin turbo V12 that are VERY underrated. A nice ECU tune will have you beating SL 65's and CL 65's.


As for the Clubs let me know what you found. I still have yet to see a Cl55, S55, or another E55 Kompressor

 

absolutely fantastic information, thanks, exactly what I was looking for

I'm trying to figure out right now if I want an E55 or an S55, but I know I want that motor. s/c v8 is much easier to maintain than a tt v12. I've had enough of turbo cars for a little while. My other car has an s/c v6 that I beefed up the intercooling on, so I'm sure I can figure something out for this V8 as long as I don't have to fab an i/c manifold.


benzworld and mbworld have local GTGs in MD and occasionally VA

 

I prefer S-Class to E-Class personally.
