What bolts do these conrods use and how should I tighten them?
These rods use ARP conrod bolts, usually ARP2000 as standard with L19 or CA625+ available on some models. ARP2000 bolts are generally torqued to around 55 ft-lb for 3/8 inch and around 75 ft-lb for 7/16 inch when using ARP Ultra-Torque lube. L19 bolts must be tightened by stretch, not torque. Always refer to the latest ARP instructions for exact specifications.
Do these conrods have a horsepower rating or warranty?
No. Like other performance rods, they do not carry a horsepower or performance warranty. Spool warrants workmanship before installation, but once fitted, power handling depends entirely on machining, clearances, tuning, fuel, boost level and rpm.
Do the big end and small end need machining?
They often do. Crank journals and pin bores vary between engines, so your builder should measure the big end oil clearance and small end pin clearance and hone as required before assembly.
What are the recommended machining requirements for the SCR5425 conrods?
The SCR5425 conrods may require big-end honing to ensure proper fitment on the crankshaft journals. It's essential to check the big-end bore for clearance and ensure it matches the crankshaft specifications. Additionally, verify that the small-end pin bore is compatible with the piston pin.
What is the weight of the SCR5425 conrods and how does it affect performance?
The SCR5425 conrods have a total weight of 427 grams, with a rotating weight of 301 grams and a reciprocating weight of 126 grams. A lighter conrod can improve engine response and RPM capability, but ensure that the overall strength and reliability are not compromised, especially in high-performance applications.
Can the SCR5425 conrods be used in a turbocharged application?
Yes, the SCR5425 conrods are suitable for turbocharged applications, provided that the engine is properly built and tuned. Ensure that the machining, clearances, and tuning are appropriate for the expected boost levels to maintain reliability and performance.
What type of fasteners are included with the SCR5425 conrods?
The SCR5425 conrods come with custom-designed WMC 5/16 bolts. These bolts are engineered for high strength and reliability, making them suitable for performance applications. Always follow the manufacturer's torque specifications for installation.
What is the centre-to-centre length of the SCR5425 conrods, and how does it affect engine assembly?
The SCR5425 conrods have a centre-to-centre length of 5.47 inches (139 mm). This length is critical for maintaining the correct geometry in the engine assembly. Ensure that the conrod length is compatible with your crankshaft and piston setup to avoid issues with piston-to-valve clearance and overall engine function.
