I have a SLK 55 AMG that is a 5,439-cc AMG-built SOHC 24-valve 90º V-8. High-pressure die-cast alloy cylinder block. Refinforced crankshaft and valvetrain. Alloy Heads. Lightweight camshafts. Reinforced engine block, oil pan structure, pistons, connecting rods and crankshaft. The Net power is 362 @ 6,000 rpm. Net torque is 376 lb-ft @ 3,500 rpm. The compression ratio is 11.0:1. The induction is a Magnesium 2-stage resonance intake manifold that increaes intake runner length at lower rpm for improved response. The fuel and ignition system is a ME 2.8 engine management, Intergrated sequential multipoint fuel injection and phased twin-spark ignition which includes individual cykubder control of fuel spray, spark timing and phase, and antiknock. Electronic throttle. Two high-energy ignition coils and two spark plugs per cylinder. 100,000-mile spark plug intervals. The exhaust system is a Dual AMG low-backpressure with four polished stainless-steel tips. The fuel requirement is Premium unleaded gasoline, 91 pump octane.

I know I gave too much information, but it might be useful to answer my question.

I want to increase the horspower from 362 to above 425hp, but I prefer to have an increase of 100 hp making it a 462 hp V-8. The more the better. I was looking into turbochargers and superchargers. Turbochargers seem like a lot of labor work, but I still might do it. Superchargers are easier to put into the car. I am 17 years old so really I don't have enough money to buy an expensive supercharger. Does anybody know if I can get a Mercedes Benz Supercharger or a Turbocharger that can fit on that engine? If not does anybody know about Kleeman, Brabus, Carlssonn, or Lorinzer if they have super/turbochargers? And if not does anybody know a really good, reliable supercharger that I can put on my car? A resonable price and good to great quailty is what I am looking for.

 

Just get NOS- or a frickin' rocket.

That was helpful.

 

Kleemann will be coming out with their V8Kompressor supercharger kit for the SLK55 soon, but it is not out yet. It'll be pretty expensive... $11k+ not including install. That will put it above 550hp. aka complete monster

17yrs old with a SLK55... sounds like you shouldn't be messing with a shortwheelbase car with 550+ hp though. Dont kill yourself with the 360 it already has first.

 

Thanks Dave for the info. I contacted a Kleemann and Brabus representative. The Kleemann supercharger kit you are talking about is $16,000 to make it 550 hp with a 1 year/ unlimited miles warranty. The Brabus 6.1 Engine is $30,000 to raise it to 440 hp with a 4 year/ 48,000 mile warranty. MBZ dealerships can service both companies under the warranty.

 

While I am not sure why you feel it is necessary to inform us all that you are seventeen years old in most of your posts, it is obvious that what you are proposing is an expensive venture. Upgrading an engine like this - though well contructed and strong, will cost a good deal of money. Plan on budgeting about $15,000 for a good job.
You might go an alternat route - find a wrecked SL55, E55, S55 or a CL55 AMG and buy its hopefully undamaged supercharger for a very low price and have it installed.
Good luck with your engine modding.
