Mark Cummings on the other MB board had it put in his C230 (auto) by Vadim at Evosports in Huntington Beach and he's happy with it. Looking at the dyno results it provides about 10 hp most of the time and up to 30 hp at high speeds. Certainly worth looking into, specially combined with other mods like a pulley kit or exhaust. Evosports does it all. They told me they were putting together a group buy on their supercharger overdrive pulley kit when it's available so if you're interested let me know. They pulley is good for about 20-30 hp across the power band. Also they were talking about an underdrive pulley kit for the rest of the appliances for another 8 hp gain. I hoping the combination will give me over 200 hp at the rear wheel (in stock form I'm 167.7 at the rear wheel).<br> <br>
