Magnuson SledgeHammer Overdrive KitThe “SledgeHammer” overdrive kit is designed for those AMG
M156 applications where a higher level of boost is desired from the Magnuson
Hammer Supercharger. Please note that this product should only be employed
where the engine and driveline has been appropriately upgraded to handle the
significant increase in power and torque that can be achieved with SledgeHammer.
Upgraded injectors with plug-n-play harness adaptors are available from
Magnuson, however a custom tune will be required. As with any overdrive system,
this upgrade will void the Magnuson warranty.By retaining the OEM 6PK harmonic balancer, FEAD components
& belt, the 8PK IFESD (Independent Front End Supercharger Drive) enables a
wide selection of supercharger drive ratios without affecting any other
components. The overdrive crank pulley is driven via four solid axial dowels
that are keyed into the OEM harmonic balancer. An optional installation kit
complete with guides, drill-bit & reamer is available for the OEM pulley
preparation.The SledgeHammer tensioner is a low profile heavy duty
solution that has a wide swing angle and ensures appropriate tension is applied
at all times.Note: Please specify what size crank pulley and supercharger pulley you require when ordering.
