Sorry for your bad experience. Sometimes running street cars on tracks can be a learning process.

PS. Hydrolock is pretty unlikely. More likely a cracked piston or a spun bearing. But you won't know for sure until the head is lifted.

I'm with you. The pump's not capable of delivering enough to lock one cyl, and engines have been run with liquid pouring out of the exhaust valve. OP -- Was the nozzle in good shape?

Overpressurization and a defect might do it....seize a piston or equiv at high RPM and....bang?

That said I haven't read much beyond this - very interesting!

OP -- What's become of the damaged motor?
