Blown engine at Watkins Glen
I blew my engine at Watkins Glen and have a new one going in the car now. The car is a Ap1 with a F22C. Since my last track day at NJMP I've been dealing with a weird high RPM hesitation/loss of power issue. There is no noise, no cel, or anything else but the car just feels like it looses power and regains it intermittently. The problem got worse at Watkins Glen this weekend.
I changed the MAP sensor (with zip tie mod), changed the coil packs, plugs, and went out with a full tank every time. The car would perform great for a few laps and then the issue would start up again. Finally the motor just gave and now I have a nice hole in the side of the block.
I have a new motor for the car but I trying to diagnose what the issue could have been. I have a larger radiator, oil cooler, and a Canton oil pan.
Anyone have this experience before?

Only time I've put a hole in the side of the block was years ago in an Alfa Romeo. Threw a rod when a bearing failed. Gotta be lubrication related. An oil analysis will usually warn of imminent bearing failure and would be something I'd do with a engine I was racing. The Army doesn't even change the oil in things like tank engines until the oil analysis says to. Occasionally we'd get a "change the engine" message. Other than needing a wrecker the power pack in a tank is dirt simple to change. Un-plug and play.
