Super Shroud Doghouse Fan Shroud - 36HP Style - Chrome or Black - With/Without Heat

EMPI Engineers have done it again! Extensive development, CAD modeling, 3D scanning, and real-world flow testing have yielded a proprietary EMPI fan shroud that cools more effectively, directs air more efficiently, and fits better than ever before.

These later style Doghouse Super Shrouds deliver more air volume than existing OEM or aftermarket shrouds for increased cooling capacity while retaining the classic 36hp Style fan shroud shape. Internal fin shapes and placements were optimized using Computational Fluid Dynamics (CFD) software and empirical flow bench testing. 3D scans of multiple engine cases and cylinder tins were used to ensure the best fitment possible. Plus, the Super Shroud can accommodate your choice of stock (28-30mm) or thicker (37mm) fans. This is beneficial since the larger fan produces significantly more air than the thinner ones.

The EMPI Super Shroud features multiple elements that have been completely redesigned for a cleaner, OE Style look while delivering improved engine performance and longevity when compared to OEM and existing aftermarket shrouds including:

Added Velocity Stack Inlet on the back of the shroud, mimics the one found on the Porsche 356 OEM shroud, to increase airflow into the fan and to enhance the cooling capabilities of the shroud.

Improved air balance across the engine, OE-style and existing aftermarket shrouds are typically imbalanced, favoring the passenger side (1 & 2 cylinders) versus the driver side (3 & 4 cylinders). This imbalance can lead to inconsistent heating between the sides of the motor. The EMPI Super Shroud corrects the imbalance while still delivering increased airflow across both sides of the engine.

Balanced oil cooler air feed, ensures the external oil cooler in the Doghouse receives adequate airflow. EMPI Engineers used a scoop inside the shroud to improve the airflow to the oil cooler for better oil temperature management, without impeding the airflow to the engine.

Extended cooling fin tips to simulate the OEM thermostat vanes; while many OEM thermostats have been deleted or no longer function properly, EMPI engineers extended these tips to replicate air straightening functionality of the thermostat when it’s in the “on” position.

Redesigned lower edge profile improves fan shroud fitment on OEM and bubbletop engine cases for easier installation and a better seal to the engine tin when compared to previous EMPI shrouds.

Horizontal alignment of the alternator bolt holes and removal of unnecessary holes makes for a better-looking shroud that contains the airflow more completely.

Extensive testing confirms that the EMPI Super Shroud delivers more air to all the critical locations:

38% more cooling air flow (cubic feet per minute) to the cylinders and heads when upgrading from the OEM early style non-doghouse fan shroud (w/37mm fan)

7% more total air flow to the cylinders/heads than the OEM doghouse shroud (w/37mm fan)

23% more air flow to the cylinders/heads than existing EMPI/aftermarket doghouse shrouds (w/37mm fan)

242% more total air flow to the oil cooler than the OEM doghouse shroud (w/37mm fan)

42% more total air flow to the oil cooler than existing EMPI/aftermarket doghouse shrouds (w/37mm fan)

Super shrouds are available in semi-gloss black paint or chrome finish with optional heater ducts.

Performance Doghouse Fan Shroud – Custom Finish & Heat Options

This 36HP Style Doghouse Fan Shroud provides the classic, rounded look of early vintage Volkswagens while utilizing the highly efficient doghouse cooling technology of later dual-port engines. We offer this shroud in several configurations to perfectly match your build—choose between a show-quality Chrome or satin Black finish, and select the version that best fits your exhaust setup (with heater ducts for stock boxes or without ducts for J-tubes).

The "Doghouse" design is a significant upgrade for any performance engine. By placing the oil cooler in its own isolated compartment at the rear of the shroud, the fan can pull in fresh air and channel it directly over the oil cooler without pre-heating the air meant for the cylinders. This setup is essential for 1600cc to 2332cc engines to maintain safe operating temperatures.

Detailed Vehicle Compatibility (Will fit the earlier years listed if the engine has been swapped with dual relief 1600cc based engine originally available in 71 and onward)

VW Thing:

• 1973, 1974

Product Highlights & Features

• Custom Appearance: Available in Chrome for a show-ready engine bay or Satin Black for a factory-plus look.

• Heater Versatility: "No-Heat" variants offer a cleaner look for performance headers, while "With-Heat" variants maintain full cabin heater functionality.

• High-Volume Air Flow: Uses the wider 36mm fan to ensure enough air pressure is generated to cool both the engine and the oil cooler simultaneously.

Technical Specifications

• Engine Application: Type 1 Air-cooled (1300cc - 2332cc)

• Fan Requirement: 36mm Wider Style (Required)

• Design: Rounded 36HP Style with Doghouse exit

• Construction: Heavy-gauge stamped steel

Installation & Maintenance Tips

• Fan Selection: Ensure you are using the correct 36mm wide cooling fan. Using an older 31mm fan will significantly reduce cooling efficiency and could lead to engine damage.

• Tins Required: Installation requires the 2-piece doghouse exhaust tins to properly vent hot air out of the engine compartment.

• Fitment Adjustment: As with all aftermarket sheet metal, minor adjustments or "massaging" of the edges may be needed to ensure a tight, rattle-free seal against your specific engine case and cylinder tins.
