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 specific machining requirements for the Carrillo conrods SCR5146?
The Carrillo conrods SCR5146 may require honing of the big-end or small-end to achieve the correct journal and pin sizes, as there can be variations in OEM specifications. Always verify clearances with your engine builder.
What is the recommended application for the SCR5146 conrods?
The SCR5146 conrods are designed for high-performance applications in BMW M40, M42, M43, and M44 engines. They are suitable for both street and racing use, providing enhanced strength and reliability under increased power levels.
What is the weight of the SCR5146 conrods?
The total weight of the SCR5146 conrods is approximately 500 grams, with a rotating weight of 346 grams and a reciprocating weight of 154 grams. This lightweight design contributes to improved engine response and performance.
How do I ensure proper installation of the SCR5146 conrods?
Ensure that the conrods are installed with the correct orientation and that all fasteners are torqued or stretched according to ARP specifications. It's crucial to follow the manufacturer's guidelines for installation to maintain reliability.
What is the centre-to-centre measurement of the SCR5146 conrods?
The centre-to-centre measurement of the SCR5146 conrods is 5.512 inches (140 mm). This dimension is critical for ensuring proper fitment in the engine assembly.
