I just looked at the pics of the rods again. The reason the rods cracked was they bent and then came in contact with the crank counterweights. The evidence is all over the bottom left side of the rod pic towards the wrist pin side.
The motor was making a "ticking" sound (rod brushing against the crank) that either was ignored, thought they had a lifter problem or simply didn't understand the sound.
This is probably the stage jhaung25's motor was just prior to the rod breaking loose.

Not long enough...

sometimes things aren't what they seam.
i inspect high stressed metal for a living and X-ray and use Ultrsound on steel ona daily basis and tell people how close they are to destroying things.
wish i still had a RM-80 piston i pulled out of a running bike that had a hole melted in the top and the strange part was that there was a rounded bolt shoved through the hole with some kind of epoxy jb weld crap under it with a lock washer and nut on the back side and the G damn thing Held compression for like 2 years with this kid running the **** out of it the cumbustion chamber had a nice dent in it from getting hit by the bolt head the first few times until it had enough clearance.
glad u made it out safely you doing anything cool in the bottom end Ti rods? any oil galley mods? any aero mods to the crank? how about some of the new black diamond oil holding bearing coatings?
how about oil pump mods? coatings?

Paulie has shared with me that he prefers to be lightly sedated for his procedure: A small amount of benzodiazapine, a glass of white wine, some soft music and the gentle touch of his "health care provider/longtime companion" Chuck.

Anything is possible but my personal opinion is that there was damage done early on most likely do to fueling issues before you had your 5 bar. Unfortunately, I don't think anything is provable one way or the other. So we will never know for sure and are left to speculate. Whatever the cause I'm glad that you dogged a potentially catastrophic engine failure.

just give him some of your "ruffies" and he'll never even remember

500 miles? 1000 miles? 2000 miles? it is just difficult for me to believe that since you went with the EVOMS GT30 package and drove it "not long enough", that all of a sudden the rods have seen so much stress due to the added hp and tq that the rods have bent, cracked, etc. That seems to be EVOMS "theory" in your particular case. If that is indeed still EVOMS position, then ALL rods should fail when driven "not long enough".

Probably easier to count the number of engines over 700 whp that have not had some damage in them. All these new builds, multiple build projects, etc. Yet, I have not heard of many motors grenading at under 650 whp. Seems like for long term driving sticking to the 600-650 whp on stock internals is a good reference. I am sure that most people going to big hp already know that risk and realize that their engine is not going to last at those power levels.
The old saying still holds true. if you want to play, you gotta pay. If you want to go to 800 whp with the big boys, then spend the time with an engine build. That or you will be selling your car in a year to avoid that bill and some poor schmuck will buy it off you not knowing the impending doom of it's engine. you escaped that bullet, but you handed it over to some unsuspecting buyer. not very cool.
I cannot afford an engine build, so in essence I cannot play with the big boys, but I won't sacrifice my engine or dump it on some unsuspecting buyer either. I am safe and my lower 600 whp level and happy with that for now. when and if I decide my kids don't need college I'll go play with the big boys.

Sadly there's no way to know when the damage began and if the rod did hit the crank counterweight then that certainly explains the crack though not the bend in the first place that caused them to snuggle. We'll never know but in the end this is a success story because it didn't blow so please don't get me wrong.
Rebuilding a bottom end is expensive! So convincing folks who work hard for a paycheck to do it when their engines appear to run well is going to be understandably tough be it a Honda or a Porsche. If there was some process where this could be done with a little less pain and KNOWN pricing up front rather than the La Brea money pit adventure so many owners seem to experience then the process might be easier to enter into. It's been pointed out such a process exists - except I cannot find out anything about it except via word of mouth. I can buy a set of 4 rods for something like a Subbie for around a grand that will hold 900HP so getting a set of 6 rods for a Porsche to hold that much and likely more since it's across 2 more cylinders shouldn't cost 2x and 3x that should it? See where I'm coming from?
