The Edelbrock 1615 Performer Rear Cylinder Head for 92-99 Harley-Davidson 1340 Evolution engines is a high-performance upgrade for your motorcycle's engine. This cylinder head is part of Edelbrock's Performer Series, which is renowned for its ability to provide increased power, improved throttle response, and enhanced engine efficiency.
The 1615 Performer Rear Cylinder Head features a unique design that includes a 60cc combustion chamber and a 2.020 intake and 1.600 exhaust valve size. These specifications allow for a larger air and fuel charge to enter the cylinder, resulting in more combustion and, ultimately, more power. The increased combustion also improves engine efficiency, as more fuel is burned effectively, reducing waste and improving fuel economy.
The cylinder head is also equipped with 5/16-inch 6-bolt mains, which provide increased strength and durability. This is crucial for high-performance applications, as the increased power and pressure put a greater strain on the engine's components. The 5/16-inch 6-bolt mains also provide a more secure fit, reducing the risk of failure due to loosening or separation.
The 1615 Performer Rear Cylinder Head also features a 3-angle valve job, which optimizes the valve angles for maximum flow and efficiency. This design reduces turbulence and improves the intake and exhaust flow, allowing more air and fuel to enter the cylinder and exit the engine. The result is increased power and torque, as well as improved throttle response and engine performance.
The cylinder head is also finished with a durable black ceramic coating, which provides protection against corrosion and heat. This coating also provides a professional and polished appearance, making it a great aesthetic upgrade for your motorcycle.
In summary, the Edelbrock 1615 Performer Rear Cylinder Head is a high-performance upgrade for your 92-99 Harley-Davidson 1340 Evolution engine. It features a 60cc combustion chamber, 2.020 intake and 1.600 exhaust valve size, 5/16-inch 6-bolt mains, and a 3-angle valve job for increased power, improved throttle response, and enhanced engine efficiency. The cylinder head is also finished with a durable black ceramic coating for protection and a professional appearance. This is a great upgrade for any Harley-Davidson enthusiast looking to improve their engine performance and take their motorcycle to the next level.
