Super Shroud Doghouse Style with Fresh Air Ducts, Black

OVERVIEW

The EMPI Super Shroud represents a revolutionary advancement in air-cooled Volkswagen thermal management, combining the iconic, sleek aesthetics of the vintage 36hp fan shroud with the high-performance cooling capabilities of a modern doghouse system. Engineered for the serious enthusiast who refuses to compromise between form and function, this shroud was developed using state-of-the-art Computational Fluid Dynamics (CFD) software and validated through rigorous empirical flow bench testing. By utilizing 3D scans of various engine cases and cylinder tins, EMPI has ensured that this shroud provides the most precise fitment available on the market today. Unlike standard aftermarket shrouds that often suffer from poor internal air distribution, the Super Shroud features optimized internal fin placement that directs air exactly where it is needed mostcooling your cylinders and heads while simultaneously feeding a massive volume of air to the external oil cooler. This is the ultimate cooling solution for high-performance stroker engines or daily drivers operating in extreme climates where heat is the enemy of longevity.

Performance gains with the Super Shroud are nothing short of extraordinary when compared to original equipment or standard aftermarket options. It features an integrated velocity stack inlet on the rear, a design cue inspired by the legendary Porsche 356 OEM shrouds, which significantly reduces intake turbulence and accelerates air into the fan. When paired with a high-capacity 37mm fan, the Super Shroud delivers a staggering 242% more total air flow to the oil cooler than a stock factory doghouse shroud and 38% more cooling air to the cylinders and heads than early-style non-doghouse units. Even when compared to modern standard doghouse shrouds, the Super Shroud provides a 23% increase in airflow to the critical cylinder areas. Finished in a durable, high-quality black coating and equipped with fresh air ducts for your heating system, this shroud offers a "best of both worlds" scenario: the clean, narrow look of an early VW engine bay with the cooling power required for modern displacement and sustained highway speeds.

PRO TIPS

1. Maximize Performance with the 37mm Fan

While the Super Shroud is compatible with standard 28mm and 30mm fans, you are doing your engine a disservice if you don''t upgrade to the 37mm wide fan. The Super Shroud was specifically engineered with the internal volume to accommodate this larger fan, which moves a significantly higher volume of air. This combination is what unlocks the advertised 242% increase in oil cooler airflow. When installing the 37mm fan, ensure you are using the correct late-model fan hub and that your alternator or generator stand is properly shimmed to prevent the fan from contacting the shroud backplate. A properly centered fan is critical for both noise reduction and cooling efficiency.

2. Seal the Engine Tin for Total Thermal Control

The best fan shroud in the world won''t save your engine if you allow hot air from the exhaust to recirculate back into the intake. When installing the Super Shroud, you must ensure that your "hoover bit" (the specialized tin that wraps around the oil cooler) is present and that all engine bay sealsincluding the rear apron seal and the spark plug wire grommetsare in perfect condition. The Super Shroud creates immense pressure inside the tinware; if there are gaps in your engine tin, that precious cooling air will escape before it ever reaches the bottom of the cylinders. Use high-quality rubber seals to create a pressurized "cold zone" above the engine for maximum cooling effect.

3. Check Carburetor and Linkage Clearance

Because the Super Shroud utilizes a 36hp-style shape but maintains the doghouse width at the rear, it is much more compact than a standard square-style shroud. However, if you are running dual carburetors, you should always mock up your linkage before final tightening. The sleek curves often provide more room for air filters than a stock shroud, but the fresh air ducts for the heater boxes can sometimes interfere with specific aftermarket throttle cable routes or hex-bar linkages. Always check for full throttle range of motion to ensure the linkage doesn''t bind against the shroud''s unique contours. Additionally, if you are not using a heater, ensure you cap off the fresh air ducts to prevent air pressure loss, though we recommend using them to keep your engine''s cooling system operating as intended.
