Mercedes CLS55 AMG W219, Installing The Best Supercharger Belt, The Gates K080507RPM

Installed the best supercharger belt you can buy, the Gates RPM series. RPM standing for: Racing – Performance – Muscle.

As I am driving with a stock setup (stock supercharger pully & stock crankshaft pulley), the correct belt is the K080507RPM. I also made some comparison pictures, as I seem to have collected all the Gates belts!

  • Mercedes Benz Gates OEM / A1139970192
  • Gates Fleetrunner / 8PK1289HD
  • Gates Fleetrunner HD Green / K080510HD
  • Gates RPM / K080507RPM 8PK1289

The RPM belt seems to have the most “grippy” material.

Mercedes CLS55 AMG W219, Upgrading To The Gates HD Fleetrunner Micro-V K080510HD 8PK1294 Supercharger Belt

It was apparent that the best in Supercharger belt would be the very popular green “Gates HD” belt, but it seems there is an even better one (more on that later).

When I ordered this belt, at the moment I thought this was the best that Gates had to offer. Its very popular as an upgrade belt and you will see it being used on many M113k engines (stock & tuned).

This belt should prevent slippage (meaning lost power) and will last a long time.

I have a stock supercharger pulley, so 1294mm is the correct belt length.
