AMR 500 Supercharger


The AMR 500 Supercharger is a small Roots type unit with about 500 cc displacement. It is the heart of the V4 M.O.A.B AMR 500 Kit for a small bump-in power on 4-cylinder engines, such as the BMW M40/M42/M43/M44.

This supercharger gives an increase of about 30 HP ~ 50 HP. 

Note: If you are buying this Supercharger for your V2 or V4 Kit, then kindly buy it as a bundle together with the kit to receive a bundled discounted price.  If you are a existing customer and want to buy one of our superchargers please contact us.

The AISIN AMR 500 is a 500 cc dual-lobe, dual-rotor compact heavy Roots type positive displacement supercharger developed by WANKEL in Korb, Germany and manufactured in license by OGURA-Clutch Co. Japan. This supercharger is small and produces just enough boost for a 1.6 – 2 l 4-cylinder engine. It has the ability to spin both ways and still make power.

The AMR 500 supercharger is used for our V4 M.O.A.B. AMR 500 Kits.

Please note:

  • Condition: Our Supercharger units are reconditioned and / or refurbishment units typically imported from Japan, Singapore or Malaysia. A basic quality check is also done by us and the product is offered with its own limited warranty period.
  • Continuous Speed: The manufacturer recommends that the product is never driven beyond 12000 RPM continuous speeds. It can tolerate a very brief burst speed over this recommended limit however prolonged exposure to anything beyond the limit will cause the supercharger to fail. Therefore if buying this for a project, size your crank drive pulleys accordingly.
  • Oil Level: Superchargers may ship without oil depending on your country, kindly use the correct supercharger oil or contact us for advice. Improper oil can destroy the gears.
  • Water / Meth Injection: You must not use Water or Meth Injection on the Supercharger as it will wear off the coated lobes from the constant heat and cool down cycles.
