Hydra HPA Engine | Gen 2 | Thompson | Wolverine

Hydra HPA Engine Gen 2 Thompson Wolverine – for your replica

This HPA engine from Wolverine is an advanced drop-in system specifically designed for replicas with offset nozzles such as the Thompson, M14, and P90. The hybrid open/closed bolt system ensures precise BB placement in your hop-up unit, while the integrated air regulation delivers consistent performance during every skirmish. If you are switching from AEG to HPA or want to upgrade your existing HPA setup, this engine offers the reliability and versatility you are looking for.

Technical specifications

The HYDRA Gen 2 features a green finish and is equipped with a US fitting for your air hose. The system operates at an adjustable pressure of 60-140 PSI and offers an adjustable rate of fire from 5-35 RPS. The engine comes with the Gen 2 Premium FCU (Fire Control Unit) and supports a battery input of 6-8V. The front bushing plate stabilises the nozzle, while the integrated filtered line ensures clean air supply. The complete system is compatible with all Wolverine Airsoft electronics.

Compatibility and application

This HPA engine is designed for replicas with offset nozzle gearboxes and fits specifically in Thompson variants. The system is also suitable for other platforms such as the M14 and P90. Installation requires technical knowledge of HPA systems and gearbox assembly – this is not a plug-and-play upgrade for beginners. You will need an external air source (HPA tank with regulator) to use the system. The engine is fully compatible with standard hop-up units and aftermarket upgrades.
