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 is the recommended machining for the Carrillo conrods SCR6506?
The Carrillo conrods for the QR25DET may require honing of the big-end bore to ensure proper fitment on the crankshaft journal. Always check the specific clearances with your rotating assembly.
What is the weight of the SCR6506 conrods?
The total weight of the SCR6506 conrods is 474 grams, with the rotating weight at 342 grams and the reciprocating weight at 132 grams. This weight contributes to the overall performance and balance of your engine.
Can I use these conrods in a stock QR25 engine?
While the SCR6506 conrods can be used in a stock QR25 engine, they are designed for performance applications. Ensure that your engine is properly built and tuned to take full advantage of their strength and durability.
What type of fasteners are included with the SCR6506 conrods?
The SCR6506 conrods come with custom-designed 3/8 WMC bolts, which provide a strong and reliable connection. Always follow the manufacturer's torque specifications for installation.
What is the pin bore size for the SCR6506 conrods?
The pin bore size for the SCR6506 conrods is 20mm. Ensure that your pistons are compatible with this pin size for proper assembly.
