Super Shroud, 36hp Style, Black with Ducts

OVERVIEW

The EMPI Super Shroud represents a massive leap forward in air-cooled cooling technology, blending the iconic vintage aesthetic of the early 36hp fan shroud with cutting-edge modern engineering. For decades, VW enthusiasts had to choose between the sleek, rounded look of the 36hp style shroud and the cooling efficiency of later doghouse designs. This Super Shroud eliminates that compromise by utilizing Computational Fluid Dynamics (CFD) software and empirical flow bench testing to optimize internal fin placement and shape. Unlike standard aftermarket shrouds that often suffer from poor air distribution, the EMPI Super Shroud features a Porsche 356-inspired velocity stack inlet that dramatically increases air intake volume. This ensures your high-performance engine stays cool even under heavy loads, providing the peace of mind every air-cooled owner deserves when pushing their machine to the limit.

Engineered with precision, this shroud addresses one of the most persistent flaws in original Volkswagen cooling designs: the airflow imbalance between the driver and passenger sides of the engine. While OE and most aftermarket shrouds tend to favor cylinders 1 and 2, the Super Shroud corrects this bias, delivering balanced cooling across all four cylinders to prevent localized hot spots and potential engine failure. It is designed to be versatile, accommodating both standard 28-30mm fans and high-capacity 37mm fans for maximum cooling potential. With its sleek black finish and integrated heater ducts, this shroud is the ultimate upgrade for builders who demand a show-quality engine bay without sacrificing the longevity and performance of their Type 1 upright engine. Whether you are building a period-correct Cal-Looker or a high-revving street sleeper, this shroud provides up to 42 percent more cooling capacity when paired with a remote oil cooler and 37mm fan compared to stock setups.

PRO TIPS

1. Optimize the Seal for Maximum Cooling Pressure

When installing the EMPI Super Shroud, the most critical factor for cooling performance isn''t just the shroud itself, but how well the rest of the engine bay is sealed. Air-cooled engines rely on a pressure differential; the fan draws cool air from the top, and the tinware forces it down through the cylinder fins. If your engine bay seals (the rubber "H" seals) or the small "tin-to-shroud" screws are missing, hot air from the exhaust will be sucked back up into the shroud. Always ensure every single screw hole is filled and that your engine-to-body seal is airtight. Even a small gap can lead to a significant increase in cylinder head temperatures, negating the benefits of the Super Shroud''s advanced internal vane design.

2. The 37mm Fan Upgrade Strategy

If you are building a stroker engine or a high-compression street motor, we strongly recommend pairing this shroud with a 37mm high-capacity fan. While the shroud works perfectly with a stock 30mm fan, the Super Shroud was specifically designed to handle the extra volume of the 37mm unit without creating turbulence or "choking" at high RPMs. Note that when moving to a 37mm fan, you must ensure you have the correct wide fan hub and that your alternator or generator pulley is properly aligned. This combination is what allows the system to achieve that massive 37 percent increase in cooling CFM, which is vital for maintaining valve seat integrity on high-performance builds.

3. Check Component Clearances During Dry Fit

Because the Super Shroud features a wider, more robust profile than some "cheap" 36hp knock-offs, it is essential to perform a dry fit with your intake manifold and carburetor setup. If you are running dual carburetors, such as Weber IDFs or EMPI HPMXs, check the clearance between the air cleaner bases and the heater ducts. In some tight configurations, you may need to slightly adjust the linkage geometry. Additionally, ensure that your spark plug wires are routed cleanly through the provided grommet holes in the tinware to prevent them from rubbing against the shroud''s edges during engine vibration. Taking ten minutes to verify these clearances before final assembly will prevent scratched paint and ensure a professional, show-ready finish.
