I am very interested in adding a supercharger to my 1990 300 SEL. I thought one similar to what comes on the 320 CLK might just do the trick. Are there any companies that offer kits for the car or will I have to adapt one myself. Also for KE-Jetronic engine management, what type of augmentation is required for fuel and spark under boost conditions? How much am I limited with a 9:1 compression ratio?

Thanks, Motor Head
