Connecting rods are a wear item, if our buddy would replace the rods once in a while he would not have any issues LOL ! one cannot expect to beat the crap out of a engine for a entire race season, have it repinched, then run the crap out of it for another 2 gallons without changing the rod...that is disaster waiting to happen.....As you know our buddy runs hard and fast and shows the engines little mercy... The Nova R7 is a top notch rod, but even it has its mechanical limits.our buddy just pushed beyond the rods limits and its as simple as that.........Rods do need to be changed out if you run the engines really hard......especially if the rod has had to go thru 2 breakins.........

here is one of the bearings I seen blow this way....this was from a stock engine to boot...the others modified....but they were a different brand of bearing in a different engine altogether..... this was from a stock P5, the other was a mod P5 the other a mod Fire 11...2 of the bearings were TKO, the other was a Novarossi.............
So what do you think the cause is?

I am not sure....but i suspect something is wrong with the bearings race to begin with......as its not a issue I have ever seen before, and its not common with any sort of correlating factor... all were runing different fuels, in different engines, different plugs and conditions..one was in Canada the others in the USA...... one engine stock, others modified , one a high end factory ceramic bearing, the others aftermarket ceramic......

on the bearing in my photo there is no sign of peeling or running dry like the one in your photo...... the bearing is pristine in all aspects other then the cracked race.... Bearing has about 6 tanks of fuel thru it from when it was installed into the engine..... This bearing here did not come apart from being beaten up like the one in your photo.....

I didn't know you had any other friends
well still the facts remain the same...a connecting rod is a wear item that has mechanical limits... If a person pushes the rod past its limits its going to give out...... This is the same for both modified and stock engines alike..... Of course how hard the person pushes the engine can play a big role in how long the rods will last..... A person can easily kill a connecting rod in one tank of fuel if they so choose to..and likewise a person can run a engine for many gallons without any rod issues if they choose to...It all comes back to owner of the engine and how they take care of their mill........
