Brooks 65 rod torque specs?

Hello, I have a new set of Brooks 65 series 6.80 aluminum rods, hemi journal .990 pin, and they didn't come with any paperwork. What are the torque specs for these? Chris

 

Call Brooks and ask Jerry. He would know what bolts you have.

Call Jerry @ Brooks 1-714-778-3315 Don

 

Most rods out there are torqued to 90 ft lbs.

 

But not all. Miller rods are 100 ft lbs. Better call Jerry.

 

Thanks guys! Chris

 

Rod Torque

Mike,

How do you torque the rods during elimination rounds when they are hot?

Are you able to cool them down in time to torque cool? If so how do you get them cool quick enough.

If you are torquing them hot do you change the torque spec?

Thanks

Could you put them in water to help cool quicker?? Not cold water! you could build a rack and hang the big end and have the piston out of the water

 

Interesting info Mike: I have the same rods and had the same question, so I called Jerry at Brooks just three days ago. He didn't mention anything about a black or a silver washer. His instructions to me were to use motor oil only (no moly or other lube), and torque them in 3 stages, first to 45 lbs, then 60, then a final torque to 75.

I wonder why the discrepancy between what Jerry told me, and the Brooks paperwork you have, that says to torque to 90?

 

if you are pulling the rods out of motor you will cycle rods with a new set...but if your checking bearings well....well..well I don't know..dave

I run venolia rods in my blown hemi with the black tapered washers and I torque to 90#s. never had a failure on the first set with over 80 runs, and this set has about 40 runs with no problem. KNOCK ON WOOD LOL

 

How much boost and rpm are you pushing your motor to H Brown? I'd like to get some life out of these, 75 passes would be great. Looking at 7500 rpm max on my motor. Chris

 

Chris i turn any where from 8200-8500. have slipped a few times when flywheel bolts broke twice and went to 9200 and 9600. my average boost #s are 32 to 34 at 33% and have gone as high as 39 to 40 # when the bolts broke. i know they say change 20 to 25 runs but me on a very tight budget and have to push the life, but my tune ups are very lazy cause we runaverage of 4.30- 4.40 ets at 3025# automatic door car.

I believe the 65's are the Chevy profile, lighter rods and are torqued at the lower torque. I am thinking they do not come with the black washer that is why Jerry did not mention 90#.

 

If I have to torque the rods when they are still really hot, I drop the torque from 90 lbs to 80 lbs. Had lots of problem pulling the threads out of the rods before I started doing that.
