An exhaust manifold blanket, such as the 60mm Wastegate Blanket Titanium, enhances engine performance primarily through heat management. Here's how it works:

1. Heat Retention: The blanket wraps around the exhaust manifold, which is the component that collects exhaust gases from the engine cylinders. By insulating the manifold, it helps to retain the heat within the exhaust gases. This can prevent heat loss and keep the exhaust gases at a higher temperature as they exit the engine.

2. Improved Turbocharger Efficiency: Many exhaust manifold blankets are used in conjunction with turbocharged engines. By keeping the exhaust gases hotter, the blanket helps to maintain the energy and velocity of the gases as they pass through the turbocharger. This can result in quicker spool-up times for the turbocharger, reducing turbo lag and improving overall engine responsiveness.

3. Reduced Under-Hood Temperatures: Insulating the exhaust manifold can also lower the overall temperature in the engine bay. This helps to reduce the risk of heat soak affecting nearby components, such as electrical systems or intake components, which can in turn improve their performance and reliability.

4. Enhanced Exhaust Gas Flow: Maintaining higher exhaust gas temperatures can also contribute to better exhaust flow dynamics. This can potentially lead to improved scavenging effects in the exhaust system, which helps the engine to expel exhaust gases more efficiently.

5. Protection and Durability: Additionally, exhaust manifold blankets made from materials like titanium are often lightweight and durable, providing protection for surrounding components from the intense heat of the exhaust manifold.

Overall, an exhaust manifold blanket enhances engine performance by optimizing heat management, improving turbocharger efficiency, reducing under-hood temperatures, enhancing exhaust flow dynamics, and providing protection to nearby components.
