I'm looking to add to the 275ish HP that my stock 2002 CLK 430 has. A Kleeman Supercharger is out of the question for now, due to the cost. Plus, I really don't think that it's the best bang for the buck.

I'm not looking to go crazy but I'd like to at least get it up around the 300-325 HP that I had in my stock 1998 Convertible Trans AM (I sold it for the CLK) and that car went like stink.

Can anyone confirm whether installing 2 K & N air filters do anything at all (total of 5hp?)?

What about the following:
AMG Exhaust-Is Amg the same name as Brabus?
Brabus Exhaust - HP?
Underdrive Pulleys - 13HP?
Headers - 136HP-this is the # that I saw-can this be right?
AirBox- HP?

What do you guys recommend? Please include approx HP gain and an idea on the cost.

Thanks.

you miss out ECU go Renntech website they will list all the airbox.... thing out.

Headers - 136HP-this is the # that I saw-can this be right?


I highly doubt it. Thats A LOT of hp from just headers. LOL.

I suggest is pulleys are the best bang for the buck with NO side effects.

ECU usually doesnt do much and is dangerous especially if they forward your timing and raise your RPM. Thats just a lot of stress for your block. If your car was turbo it would be a different story.

Exhaust and intake is good for at most 10hp to the wheels. If that.

Go contact Ben @ www.evosport.com , they have UD pulley kit that works. Also I believe they can get you anything you need. He drives a CLK430 so I'm sure he can help you out.

All the parts you listed seem to all give pretty good results according to others who have them installed on their cars.

The one thing i have not seen on any MB's are ECU chips.

I contacted GIAC about whether or not they are planning to provide custom software for MB's, they do plan to release some chips but I have no idea when, I don't think anytime soon though.

Does the Brabus exhaust offer any hp gains? I don't really think so, I know Eisenhaus.com sells custom exhaust systems and claim an increase in HP from 3-6%.

I think everyone will agree that the pulley from evo is the best bang for the buck performance upgrade you can get.

Mach430

3-6% is WAY too high of gains for a replacement muffler on a Mercedes! You would be lucky to get 3-5hp out of changing your muffler. Because of the small gains, we only recommend changing the muffler based on aesthetic and sound preferences. Headers are a different story, but are more expensive to purchase and install.

I have not seen any decent ECU software for the Mercedes. Some are horrible, others just change the ECU to European settings, which advances the timing and requires higher octane. If I could find one that puts out the gains they promise (as long as they promise over 10hp), I would recommend it to everyone.

Our underdrive pulleys are the best bang for the buck. For $499 (plus installation) you will have another 13hp at the wheels (dyno proven). Unlike other mods, that don't put out much power until higher gears/rpms, the pulleys will give 13hp immediately; thus helping city driving.

...........unfortunately, it is not easy to increse HP significantly on a 430 without boring out the engine or placing a supercharger. to get up to 300HP, contact Oberklasse and get their MKB stage one kit which reportedly will increase your HP to 308HP. They are relatively expensive and when dealing with them, DO NOt do any business on-line..........they will not respond. There on-line person is truly loosing a lot of business for them.

Okay, I'm sold on the underdrive pulleys. I have also heard about the immediate and realistic gain of 13hp and the fact that there is no side effects. But how about fuel consumption? The car is already a pig on fuel in my mind. My stock 5.7 Litre 350 Trans Am was much better on fuel and faster, if you can believe that.

Either way, I'm getting the pulleys but wanted to know if anyone has any idea if they will decrease fuel economy further.

Thanks.

Given that the concept of the underdrive pulleys is to free up HP from parasitic losses, with the same driving behavior, your gas milage should go up. Your engine will be making the same power, just more of it will go to your wheels.

We are also a MKB dealer. For the cost of importing MKB parts, you should consider changing to a MKB differential.

I'm new to the world of mods for MBs (my wife made me promise not to tweak the new car), but would any of the mods for my old BMW (sorry guys) work on a CLK430?

Open air
MSD ignition
Hotter coil
Lighter flywheel
Performance cat

Petie

dont think so, CLK has dual cats, and i am sure all the other parts are different enough not to work

Larry Sonsini

Sometimes you don't know if something will work until you try it...That's why it's called tuning.

I have evosport ud pulleys, K&N air filters and AMG exhaust, and my car feels at least 10% quicker than stock. I still have the 17" wheels so 0-80 times have improve dramatically! I will call Renntech to have it dyno tested and will let you guys know how close to 300HP I am.

Arnee

Please post the graphs/numbers! I have K&Ns and the AMG exhaust also. It'd be interesting how much the UD pulleys add.

newguy2008

What is the part # for the AMG Exhaust or name of it? Approx. cost and HP claims from AMG???

Arnee

I don't have the part # for the AMG exhaust for the 430.

Autoclass.net carries them. I don't remember how much I got mine for but autoclass should have the price on the website.

I don't know if there are any claimed HP gains from AMG; it's mainly for aesthetics and a *slightly* louder tone.

Mach430

AMG exhaust will add 0-3hp (if you're lucky). Changing mufflers on most cars does not provide the power it used to. In many cases, you lose power!

Here is a before and after dyno on a customer's CLK55 last month. The humps in 1st gear are when the car lost traction due to the increased torque. As you can see by the curve up to it, the gains are noticable off the line.

tery

anyone here use the G-TECH pro thingy to test out perfomance ??
Mach430 you us it befoer ?? i want to buy one

Mach430

Here is a 1999 E55:

E320

Nah, too much of a headache for me to setup Sleestack uses it though.

tery

Sleestack is the G-tech pro good ?? do you find it useful ??
is kinda expensive and it sound a bit too good to be true.

Mach430 do you have dyno for CLK320 is it the same as E320 ?

Mach430

The CLK320, E320, SLK320, and other 320's share the same engine and accessories, so you can expect the same gains in power with our pulleys.

calboy

do you guys remember a thread a long whiles back where putting reflective tape on the intake would increase horsepower by lowering the temperature of the air (prevent engine heat from heating it up) to give 5-10 hp gains for roughly $70??
