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 360 degree thrust main bearings in my Barra XR6?
The 360 degree thrust design provides comprehensive support for the crankshaft, which enhances stability and reduces the risk of movement under high RPM conditions. This is particularly beneficial in performance applications where engine loads can be significant.
Do I need to modify my engine block to fit these ACL Race Series main bearings?
In most cases, these bearings are designed to fit standard specifications for the Ford 6Cyl AU and Barra XR6 engines. However, it's essential to check for proper clearances and ensure the block is in good condition. Machining may be required if your engine has been previously modified or if there are any irregularities.
What should I consider regarding oil clearance when installing these main bearings?
Oil clearance is critical for the performance and longevity of your engine. Ensure that the clearance is set according to the specifications for your engine build, taking into account the type of oil you will be using and the expected operating conditions. It's advisable to consult with your engine builder for precise measurements.
Can I use these main bearings with aftermarket crankshafts?
Yes, these ACL Race Series main bearings can be used with aftermarket crankshafts, provided they are compatible with the Ford 6Cyl AU and Barra XR6 specifications. Always verify the dimensions and tolerances of both the crankshaft and bearings to ensure proper fitment.
What type of oil should I use with these main bearings for optimal performance?
For optimal performance, use a high-quality synthetic or semi-synthetic oil that meets the requirements of your engine build. The oil should have the appropriate viscosity for your operating conditions, and it is advisable to follow the manufacturer's recommendations for oil type and change intervals.
