So many threads and opinions, I'd like to summarize this for all of us:
Input from all appreciated.

-ASP pulley kit what does it contain for SLK's to 2004 (like mine)
-What do you need for a 2004 SLK?
-What is the horsepower gain per model year?
-What years do you need the MAS relocation kit?
-How reliable is it?
-LEE at ASP claims a 32 HP rear wheel gain
-With 194 stock SAE, that would be about 230 SAE. Is that right?
-What is involved in the installation?
-What size belt will you need?
-Do we have to upgrade the IC, fuel injectors or remap ECU?
-OTHER?

Thanks,
JoeVee

Be aware...

Hi,
If you will go over my posts, you will never find a question, but only solutions...
Also I never disclosed my former employment with the manufacturer, nor will I now, but please read between the lines...
I am originally from Stuttgart, home to MB and Porsche (if that matters).
The stock design is meant to last for as long as the car does; if this has value to you, stop asking these questions and move on with your life. If the life of your car (or components is not important to you, go ahead). The ASP pulley will increase the rotation of more than the spindle of the supercharger; those are parts not meant, nor designed to withhold such rotations and built-up heat. ASP is a race & performance company and I do respect their work, however race cars are treated different than street cars; maintenance is not an issue and most likely there is an army of skilled d mechanics behind every race car... Now ask yourself, do you have such, or even are you willing to perform service after very low mileage in race-like conditions? If so, go ahead, if not, find solutions for better performance which will not have a negative impact over time. It's more to say, but I'm already sure some people will jump on me for what I stated so far :)
Not that I might care, because, like I said, I see myself as an asset more than a liability since all my posts provide and none so far asks...
Anyways, whatever you will decide, good luck!

It sounds like you gave an answer to the wrong question. I have no idea (or you probably) why you took this personally. I see this forum as a place to exchange ideas, improve, repair, car thoughts and discoveries with each other. It's not (and I don't know how you came to that conclusion) about you, your posts or where you work, it's simply about getting information on our SLK's to improve them, make them more enjoyable and just plain have fun.

You were probably having a bad day!

Mods, yes or no...

My day was great actually, I did not take anything personally (how so?!) and I actually know what I'm talking. I intended to be helpful and I stated a little bit of my expertise, that's all...
You are the sole person who will decide how to spend your own money and how much you will be able/willing to put in your car. Improving a Mercedes and have it last is not easy :)
Good luck and please take no offense, because it was not intended.
P.S. An improvement which will do no harm and might save you some money if done can be found in my latest post regarding transmission fluid cooling.

It seems like you are knowledgeable, why don't you enlighten us with your expertise and provide concrete answers that will help us all? It seems like you are opposed to any modifications. It's obvious that modifications jeopardize the reliability, but that is what we do! That is what drives us. Your input would be appreciated.

Thanks,

JoeVee

Lol ..


Dunno about pulley mods myself JoeVee but I'd take the remap every single time.
Had my little 200 'mapped seven years ago now and it's still going strong.




EDIT:
You'll get +30hp from a decent remap for IRO £250/whatever that is in dollars - $400ish?

Being aggressive won’t help you or others. You do whatever you please with your funds and car. Some mods will allow a better performance but for a price/compromise, other mods are harmless. It all depends on your priorities. If you’re the type who always starts first at a stop light or the type who drives long distances and cares for reliability or the type who intends to impress others… For the last ones, this won’t be possible with a $6 K car these days…
Anyways, I’m not against mods and did a lot myself, however, I never made a compromise on safety and reliability. You can drive such a car for 300 K miles with the adequate maintenance, or for 150 K with all those compromise sensitive mods, this was my intention to disclose in my first post… You do whatever you please. The 1 sec gain in reaching 60 mi/h don’t have a meaning to everybody…
As a piece of advice, I would recommend to make sure the car stops on a dime, steers like on rails and the drive-train is mint.
Good luck with whatever you will decide…

I don't get it!!!! I am simply trying to get some information on a topic that's been hammered to death in different threads and none seem to answer all of the unknowns. I am trying to make it as clear as possible for all who are interested in the pulley modification. I realize that some of you may not want to modify your cars, but apparently that seems to be a viable alternative in the forum. Just answers please!

Thanks,

JoeVee

Play nice guys....

Modifications are great for some of us, and not so for others ... I know I've done a few...

Time to get back onto the original topic - Pulleys!!!

The ASP pulley kit is just the pulley & it is very reliable.
The instructions are on the asp site
yes you will need to get a new belt.
nothing else is needed, but a retune would not hurt.
