What is the purpose of the dish volume in these pistons?

The 11cc dish volume in these pistons helps to reduce the compression ratio. This is important for forced induction applications like turbocharging or supercharging, as it allows for more boost pressure without causing detonation or pre-ignition.

Are these pistons suitable for a naturally aspirated engine build?

While these pistons are designed for boosted applications, their dish volume will lower the compression ratio in a naturally aspirated engine. If you are building a naturally aspirated engine, you might need to adjust your cylinder head chamber volume or gasket thickness to achieve your desired compression ratio.

What does the moly skirt coating do?

The moly skirt coating on these pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to improved engine efficiency, reduced wear, and a smoother break-in process.

About this part

Product Details

If you're rebuilding a 4.6L Ford Modular engine, whether it's a 2-valve or 4-valve setup, these Manley Turbo Tuff Dish Pistons are a solid choice for serious performance. They're designed with a 3.552-inch bore and feature an 11cc dish volume, making them suitable for boosted applications where you need to control compression. Manley has a strong reputation among professional engine builders for making parts that hold up under demanding conditions.

These pistons are forged from a domestic 2618 alloy, which is known for its strength and ability to handle high temperatures and pressures without deforming. Manley uses proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, while also contributing to generating more power. The ring lands and grooves are machined to very strict tolerances, which is crucial for getting a good seal from your piston rings. This improved ring seal means better compression and more efficient combustion. The set includes tool steel wrist pins for added durability, and these specific part numbers feature a moly skirt coating to further reduce friction and wear during break-in and operation.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. When you're putting these into your engine, pay close attention to the manufacturer's installation instructions, especially regarding ring gap and piston-to-wall clearance, as these are critical for the longevity and performance of your build. For a high-performance build like this, consider pairing them with quality connecting rods and a robust crankshaft to complete your engine's rotating assembly.
