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 applications for the Carrillo Conrods SCR4855?
The Carrillo Conrods SCR4855 are designed specifically for the 1.6L and 1.8L Mazda Miata engines, particularly the BP engine code. They are suitable for both street and performance applications, providing a robust solution for those looking to enhance their engine's reliability and performance.
What is the recommended machining process for the SCR4855 conrods?
When installing the SCR4855 conrods, it is advisable to check the big-end bore for proper clearance. Due to manufacturing tolerances, honing may be required to ensure a precise fit on the crankshaft journals. Always consult with your engine builder for specific machining requirements.
What is the weight of the SCR4855 conrods and how does it affect performance?
The total weight of the SCR4855 conrods is 440 grams, with a rotating weight of 310 grams and a reciprocating weight of 130 grams. The lightweight design contributes to reduced inertia, allowing for quicker revs and improved throttle response, which is beneficial for high-performance applications.
Are there any specific installation considerations for the SCR4855 conrods?
Yes, when installing the SCR4855 conrods, ensure that the fasteners are torqued or stretched according to ARP specifications. Additionally, confirm that the rod alignment is correct and that the small-end pin fits properly in the piston. Proper installation is crucial for reliability and performance.
What is the significance of the Pro-H design in the SCR4855 conrods?
The Pro-H design of the SCR4855 conrods offers a high strength-to-weight ratio, which is essential for performance applications. This design allows for increased durability under high-stress conditions, making them suitable for racing and high-performance street use. The proprietary steel forging process also enhances their overall strength and reliability.
