EMPI Super Shroud 36HP Style | VW Type 1 Heater / No Doghouse | CFD High-Flow Cooling (00-8684-0)

EMPI Super Shroud — Early 36HP Style | With Heater, No Doghouse | Semi-Gloss Black (00-8684-0)

EMPI engineers have done it again. Extensive development, CAD modeling, 3D scanning, and exhaustive real-world flow testing yielded a proprietary EMPI fan shroud that cools more effectively, directs air more efficiently, and fits better than ever before. This version is the non-doghouse style with heater.

These early-style Super Shrouds deliver more air volume for increased cooling capacity. Internal fin shapes and placements were optimized using Computational Fluid Dynamics (CFD) and empirical flow-bench testing, and 3D scans of multiple engine cases and tins ensure the best possible fitment. The shroud accepts your choice of stock (28–30mm) or thicker (37mm) fans.

Vehicle Fitment

• VW Beetle (36HP Engine): 1946–1960
• VW Karmann Ghia (36HP Engine): 1946–1960
• Engine cases: Fits both OEM and "bubbletop" cases

Why Choose EMPI?

EMPI developed the Super Shroud through CAD modeling, 3D scanning, and flow-bench testing to correct the airflow imbalance found in OE and older aftermarket shrouds — delivering more air volume, balanced cooling across both cylinder banks, and a cleaner OE-style look.

Key Features & Benefits

• Velocity Stack Inlet: An added inlet mimicking the Porsche 356 OEM shroud increases airflow into the shroud for more cooling efficiency.
• Balanced Airflow: Corrects the OE/aftermarket imbalance that favors the passenger side (cylinders 1 & 2) over the driver side (3 & 4).
• Extended Cooling Fin Tips: Simulate the OEM thermostat vanes in the "on" position for deleted or non-functioning thermostats.
• Improved Fitment: Better seal to the engine tin on OEM and bubbletop cases for easier installation.
• Clean OE Look: Horizontal alternator bolt alignment and removal of unnecessary holes contain airflow more completely.
• Versatile Fan Options: Accepts stock (28–30mm) or high-output (37mm) fans.
