I have a '98 slk 230. Now that the warranty is up on the car I am interested in adding some mods. What would be my options at increasing my horsepower? Is there anyway to get to 250hp out of the 4cyl?

 

The easiest way is with a Pulley kit. These use a larger Cran pulley to bring supercharger in earlier and give a bit higher boost. Computer adjusts mixture etc to suit.
On a 98 model the MAF should be relocated to the same place as the later 230's to prevent a 'hole' in acceleration.
This chap sells the kits complete with pulley and MAF relocation kit.

do you know how much this would be? and what does MAF stand for?

 

MAF (Mass Air Flow) or AFM (Air flow meter)

About $850 US $$ I think.. Email Linh.
