    carrillo rods torque question

    my local machine shop doesn't have a stretch gauge, what are you guys getting for your final value on the bolts? These are the carrillo bolts. I know they say not to exceed 30 foot pounds.

    So I bought the bolt stretch tool. Just for future reference if anyone needs this info, my bolts had to be torqued to 45lbs before they got the appropriate stretch value. The data sheet shows a max of 32lbs which is impossible to get the proper stretch. My Carrillo rods have the CARR SM8 bolts, not ARP.

    I have two sets installed. Proper stretch (.005-.006) came in at about 30-32 Ft. Lbs. Spinning engine to 9400 @ 25 lbs of boost. No issues.

    32lbs did not even start to stretch my bolts. Do you have the same bolts? I have the CARR SM8, after some forum searching I found a post where apparently the old tech sheet showed 45lbs max not 32.

    Yup. Same bolts. Weird. I guess as long as there stretched to the spec you should be fine.
