Review VOLKSWAGEN Air Cooled 1700cc Performance Engine. Myers Manx Sandrail

The Volkwagen Type 1 air-cooled 1680cc/1700cc performance engine, often referred to as the "Manx" or "Sandrail" engine due to its popularity in the Manx and Sandrail vehicles, is a legendary powertrain that offers impressive performance and reliability. This engine is known for its simple yet effective design, which sets it apart from more modern water-cooled engines.

The 1680cc and 1700cc variations of this engine share many similarities, with the primary difference being the displacement. Both engines feature an overhead valve configuration, with each cylinder having a single intake and exhaust valve. The cylinders are arranged in a flat, horizontally-opposed layout, which provides excellent balance and smoothness.

The engine's air-cooling system relies on a series of cooling fins that surround the cylinders and cylinder head. Cool air is drawn in through the engine's grille and forced over the fins by the vehicle's movement. The cooling system is further aided by a fan, which engages when engine speed drops below a certain threshold. This design allows the engine to operate effectively in off-road conditions, where water-cooled engines may struggle.

The Manx engine's performance capabilities are noteworthy. With the 1700cc engine, you can expect around 80 horsepower, while the 1680cc engine delivers slightly less power. Torque figures are similarly impressive, with both engines providing ample low-end grunt for off-road driving.

This engine is renowned for its durability and ease of maintenance. The air-cooled design eliminates the need for a radiator or cooling system, significantly reducing the number of parts that require maintenance. Additionally, the simple design of the engine makes it easy to work on, with common modifications such as porting, polishing, and the installation of high-performance carburetors being relatively straightforward.

In conclusion, the Volkwagen Type 1 air-cooled 1680cc/1700cc performance engine is a highly desirable powertrain for those seeking a reliable, powerful, and easily maintainable engine for their off-road vehicle. With its simple design, impressive performance, and robust construction, this engine has earned a devoted following among enthusiasts and is a testament to Volkswagen's engineering prowess.
