Description
The Harbinger Supercharger Kits
– CNC machined
– powder coated brackets
– come with a guaranteed 24 months craftsmanship warranty**.
The Harbinger Supercharger Kit is designed to be used on the BMW M50, M52, M54, S50, S52, S54 Engines and includes all hardware and basic pipe work you require to bolt on the supercharger and get it running with the engine.
The kit itself is based on a P2 centrifugal dry unit with no lubrication required, produced under Speedmaster Australia. The HB 1 / P2 is a readily available affordable supercharger rated at 1150CFM max and some 55,000 RPM from the manufacturer. Our custom machined COG pulley and belt, drives the supercharger itself while maintaining a fixed ratio, limiting the supercharger to 30,500 RPM.*
This setup will work for both stock and built engines. While a built engine will be able to handle more power, on a stock engine, we suggest limiting the boost to 10 PSI, using a boost controller and a bypass valve. The Air conditioner, Alternator, Power Steering or any other belt driven accessories are not affected by it.
The Supercharger unit is included only if you select the option Harbinger kit + HB-1 / P2 Supercharger.
If you want to only buy the supercharger then please order the supercharger separately.
To complete the installation on any of the setups, you will also require the following additional parts:
- HB 1 / Speedmaster P2 Centrifugal Supercharger
- an Intercooler Kit (for high boost) or Silicone Pipe Kit and hose clamps (for low boost)
- vacuum hose
- LF30 power steering pump and pulley from M52 or M54 engines

All parts mentioned above can be provided by us on request, at extra costs.
