What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What are the benefits of using ACL Race Series Main Bearings in my 5.7L Hemi?
ACL Race Series Main Bearings are designed for high RPM conditions, providing enhanced durability and reliability. The high strength overlay plate and hardened steel backs ensure they can withstand the stresses of performance applications, making them ideal for enthusiasts looking to maximise engine performance.
Do I need to modify my engine block to fit these main bearings?
Typically, no major modifications are required to fit ACL Race Series Main Bearings in a standard 5.7L Hemi engine. However, it's essential to check for proper clearances and ensure the block is in good condition. Some builders may choose to perform line boring for optimal fitment.
How do the 3/4 grooving features of these bearings improve oil supply?
The 3/4 grooving design in ACL Race Series Main Bearings enhances oil flow to the bearing surfaces, ensuring adequate lubrication under high load conditions. This feature helps maintain consistent oil pressure and reduces the risk of bearing failure during performance driving.
What should I consider regarding installation of these main bearings?
When installing ACL Race Series Main Bearings, ensure that the bearing surfaces are clean and free of debris. It's crucial to follow the manufacturer's specifications for torque settings on main caps and to check for proper oil clearance to ensure optimal performance and longevity.
Are these main bearings suitable for both street and race applications?
ACL Race Series Main Bearings are primarily designed for race applications where high RPM and performance are critical. While they can be used in street applications, it's important to consider the engine's intended use and ensure that the overall build supports the demands of these high-performance bearings.
