I get it up to 152 amps this time with the resistor coil in a water bath. Still at 24v, but with the oscilloscope disconnected. TVS temperature climbs pretty fast at 152 amps! But it could just be the mosfet legs getting hot, and that heat transferring to the TVS?
Here's 12v DC bus, at 29 amps, from gate to source:
