Rod Bolt Torque for Boostline Got a surprise today. After seeing a lot of different torque values for ARP 2000 rod bolts and none of them were the same as the supplier that I bought the rods from, I decided to call Wiseco and see what they said. I have the LS Boostline rods with 7/16" ARP 2000 bolts. however, found out that they are not the same as the standard ARP rod bolt. The torque value is 30 ft# plus 50 degrees. They are good for 3 uses. I have a digital torque wrench that measures angle as well as providing a torque number when you hit the specified angle and the torque was a lot more that I would have expected for a rod bolt. Numbers were consistent, so I guess it's good. The Wiseco rep refused to give me a final torque number and said to use the angle method and a stretch gauge. You can only buy these bolts from Wiseco. More throwaway bolts!!
So they are torqued at the factory. Then torqued for mock up to measure clearances. Then torqued when you Assemble the engine....
Assuming you didn't need to torque for a mock up or anything like that because if you do then you would have to throw them away and get a new set to final assemble the engine....
I wonder what makes them different? As long as they measure properly and aren't stretched why couldn't you re use them?
