NOTES:

• The Supercharger is not included in the kit and you are advised to use the given part number for the supercharger and order the supercharger locally.
• Stock M45 pulley will limit the boost to 8PSI with an air to air intercooler, For 12+ PSI you will have to rebuild the M45 Supercharger with new bearings and use any available Hyde Motor Works overdrive pulley made for the M45 Supercharger.
• On the older M42/M43 Engines with the V Belt drive system, you must upgrade to the newer Micro V belt system from the newer M42/M43/M44 engines. Having the M44 Manifold is recommended for best fitment.
• Currently the kit supports only the Eaton M45 Supercharger, future support will be added for the Eaton M62. *

To complete the installation on any of the setups, you will also require the following additional parts:

• Eaton M45 Supercharger (Mercedes variant only, check the technical specifications for part numbers)
  
• an Intercooler Kit with silicone pipes and hose clamps (can be sold separately)
  
• vacuum hose
  
• an high flow air filter
  
• a boost gauge
  
• a recirculating by pass valve and
  
• proper tune.

Please consult the installation guide for more information.
