    Default PS 89 Ka Pow!

    As some of you know we had a bit of an issue at Parker last November. Seems a rod bolt had had enough torture.....If you look at the pic of the bearing in the rod, you can see the parting line wear where the rod was elongating. Also, one bolt is broken straight, one bent trying to hold on before breaking. The block is toast, the crank junk, shrapnel messed up the cam, and it looks like a 40MM round went thru the tray. The pan had about a 9MM hole in the side but the baffles and such are fine. I'm sure Dooley will hook me up with another tray. Oh, anyone wanna buy 6 slightly used rods and pistons?...........Ray

    The rod bolts were measured prior to use, and again prior to re use when the bearings were re freshed. The bolts were torqued to spec using ARP lube. They are ARP 8740s and had about 25 heats on them. We had an issue of over revving at Blacklake last year when Mike was pitched partially out and matted the gas. The mag kill did it's job and killed the spark, but the motor was headed to a gazillion which meant the piston direction change, without spark, was all on the rods. We ran 10 1/2 heats after that so that may not of had anything to do with this, but it makes you wonder. Also in the mix is a bum rush to get wet at Parker when the ramp was full and the heat was begun without us. Chris Kenner had to cut the course, and come around for the start without the usual lap or two warm up!!. Did that have anything to do with this? We'll never really know, but THAT won't ever happen again. I'm not crying here. There is no crying in boat racing over engine or boat damage. I have another one going together with L19 ARPs. What really pissed me off was the 12 quarts of racing oil I just put in it!!!..............See ya at the races, Ray

    PS; The block was damaged on the back when a ring gear came off a flex plate on the trailer. The shrapnel smacked the cam plug area as well as a freeze plug boss and an oil restrictor was also damaged. The block, IMO is not worth sleeving. I did salvage the billet main caps for future use......

    That one was a 440. The replacement will be 468, and there is a 496 in the works as well. Aluminum rods are not the hot tip for our style circle racing. Nor are the light weight wrist pins as they tend to change shape, bend, and rip out the bottom of the piston.......Again, I aint crying here......Stuff happens

    Ray, it looks like it was Chris Fault!! No doubt in my head. The Eagle rods are decent but I would not them my first or second choice on the rebuild. Good luck Ray. Im in Newbury Park if you wanna hit up Red Robin.

    I have only ever seen 1 other broken eagle rod. Looked just like yours......big end welded itself to the crank.....broke the rod then the part of the rod that was still on the crank smashed around till it broke 1 bolt and bent the other letting everything land in or through the pan. I have never heard of an eagle rod just breaking. One of them rods breaks..... 99.9% bearing failure and/or oil issues. The big end will turn blackish blue and will actually start to melt just like candle wax.

    I wonder if any other rod could of held up after zinning it like that? What I'm gathering in these forums, is that over reving is REAL hard on rods.

    It wasn't the rod...it was the bolts and yes, over reving is a killer. Although a decent bolt, the 8740 is their basic bottom line bolt. Anything making over ~700hp, or anything in an endurance application, IMO, needs to upgrade. IMO, the 2000's aren't enough of an improvement to warrant the cost. At that point, might as well get the L19's and never look back.
    It seems that the Eagle rods themselves have proven to be a really decent piece, especially for the $$.
    If God is your co-pilot, change seats!
    Acts 2:38, the perfect answer to the perfect question.
