GMP Performance

This customer came in looking for quite a bit more power from his already stout C55 AMG. We paired him up with a Kleemann supercharger kit, Kleemann headers, and, to help get all the power down to the ground, a Quaife Limited Slip Differential.



Parts Installed:
Mercedes M113 (V8) 430/500/55 KLEEMANN Supercharger System
Mercedes M113 V8 Headers for C55 W203
Quaife LSD Differential

First, the supercharger

All stock, just waiting to get started



New supercharger bolted down


We had to remove the front bumper to route all the intercooler plumbing.




And the intercooler is all mounted


Intakes were installed and this part is all done. When compared to stock, even excluding statistics, we already see an improvement.

Stock


Versus the gorgeous new Kleemann set up


Now on to the headers we went

We quickly removed the stock headers and cats and figured we'd take a good look at the before and afters.



So bulky


And now so sleek


The Limited Slip Diff

Factory Differential


The new Quaife versus the OEM diff


We got the Quaife diff installed into the housing and back into the car.




And this job was done. It technically is a lot of work but for the benefits you receive in this combination of parts, it's well worth it. Our customer is super pleased with it and for that reason alone, we couldn't be happier.

Awesome write up and thread guys!

Would love to get the SC for my C55, just cant see myself spending 8-10g's on it at this point.

What exhaust is he running? True dual, True dual with X pipe or just factory piping for now?

ghiaguy

Yeah, I was thinking a turbo kit for my Miata was too much @ $3k. Then I bought an AMG...

Very nice work! Lucky C55 owner!

Supgee

BobC32AMG

V8 and supercharged, that will do the trick! What are the specs??

Accidental L8 apex

Before and after dynos?

Brau0318

Looks bad@#$. I would love to see numbers as well. My only question is... a 2004?

kent426

all that power on those puny tires reminds me of 60's muscle cars.

RLx02

Any estimate on cost/labor? I'm considering selling mine and going c63 route but it would definitely be cheaper to s/c it...

betrezra

Get ready for 11's

moosejaw

It would be even cheaper to put a 50 shot of NOS
remember C55Asleep? He ran high 11s.

Saaboteur

Need moar of the gif in Moosejaw's sig!!

$12,000 parts and labor SC only, no headers no cams no differential no suspension no brakes.

GMP Performance

You would be surprised how well you could get it to hook up with a good set of tires.

GMP Performance

We did a before and after and had an average increase of roughly 80hp to the rear wheels on an 80k engine.

GMP Performance

We charge $2000 for installation.

Stock exhaust with Kleemann headers

Lol at least I'm not the only guy with a less-than-spotless engine bay lol!

Clean install GMP, thanks for posting!

Any chance you remember his exact time/trap speed? I've looked since he had similar mods with his headers, cams, etc. but have never found an actual time he posted...

Nice write up

I don't know the age of this kit, but do you guys remember if it used the fuel pressure regulator under the car and the inverter module or the secondary fuel pump and regulator under the hood?

maverik259

lol $12k is just soooo not worth it for 80whp IMO.
