Had 80 passes on my Groden rods before breaking one in the water box. Destroyed everything but the bare heads. Now I run Carrillo steel rods.


Just out of curiosity how many 1000's of RPM were you at in the water box?





I've had good luck with aluminum and will continue to use it. Like I said earlier, my BME's were in the car from Jan.2001-Oct.09 without a problem. 75-100 passes a year. My next set will be GRP's and I hope for the same results. [/quote
It's interesting how many negative opinions there are about aluminum rods. I can't count the times people at the track fire up their race motors, rev the heck out of them cold, go to the burn out box cold, run 42 degrees timing etc, and when something goes wrong, they blame the parts. I'd guess the guy with 2400HP ran al uminum rods, and changes them regularly. Just a guess, but even if they're steel, he changes them regularly.


Good point about running the engine hard when cold. BME wants a minimum oil temp of 125.
I never run my engine hard unless the oil temp is 160 or higher.
