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 SCR13492 conrods?
The SCR13492 conrods for the BMW B58 and Toyota Supra typically require big-end honing to ensure proper fitment on the crankshaft journals. It's essential to check the clearances and make any necessary adjustments during the assembly process.
What is the recommended application for the SCR13492 conrods?
These conrods are designed for high-performance applications in the BMW B58 and Toyota Supra engines. They are suitable for builds that may see increased boost levels and higher RPMs, making them ideal for both street and racing environments.
What is the weight of the SCR13492 conrods and how does it affect performance?
The SCR13492 conrods weigh a total of 606 grams, with a rotating weight of 427 grams and a reciprocating weight of 179 grams. The lightweight design contributes to reduced inertia, allowing for quicker revs and improved throttle response, which is crucial in performance applications.
Can I use these conrods with stock pistons?
While the SCR13492 conrods can be used with stock pistons, it's important to ensure that the piston-to-conrod clearance is within the manufacturer's specifications. Custom pistons may be required for optimal performance, especially in high-boost applications.
What is the significance of the 3/8 WMC bolt size in the SCR13492 conrods?
The 3/8 WMC bolt size provides a strong and reliable connection between the conrod and the crankshaft. This bolt type is designed for high-stress applications, ensuring durability under extreme conditions, which is essential for performance builds.
