Radiator Shroud Fan Kits

Our fan shrouds are designed primarily for fast road or track days applications, or where further clearance is required that can't be obtained with the OEM setup. The shrouds are designed with two goals in mind, clearance and reduced airflow resistance at speed to offer superior cooling where it is needed. There is a common misconception that fully shrouded fans are better full stop, and yes this is correct to a degree but only for very specific use cases. Auto manufacturers design a radiator and shroud combo to be able to cool the engine sufficiently in a worst-case situation; a high load, low air speed, high ambient temperature scenario such as towing a caravan uphill for a prolonged length of time on a hot Summers day! Opening up the aperture around the fan itself allow our shrouds to offer less resistance at higher road speeds and improve cooling efficiency as a result.

Some of our shroud kits are available with different fans, either standard or high performance. There as so many factors involved in determining the correct airflow requirements but as a general rule of thumb, we would say the following: shrouds with 'standard' fans are best suited to applications with up to 51mm (2") thick radiators or with naturally aspirated engines. The high-performance fans would be better suited for use with extra thick radiators, radiator packages with intercoolers further upstream or in extremely hot climates.
