Ok, well I just got off the phone with Kleeman Headquarters in Colorado Springs. I asked him about upgrading my 2003 CL55 that will be arriving in a few short months and if they were planning any upgrades for the car. Well, they are. Replacing the whole supercharger unit and he says they have a prototype on a SL55 in Denmark right now that has 610h.p.!!! He told me Mercedes' supercharger is very inefficient and the engine is very capable of more power without any risk of harming it.


How much is still being determined. Its going to be arriving in January though.
