It may just be overheating..... how "hot" does it show on the temp indicator??
I def agree with the possibility of the head bolts stretching, but where's all the heat coming from?? It should not be boiling over...... If you are simply pumping cylinder pressure into the water jacket it will blow out the overflow like you're saying but not necessarily get hot.
Correct me if I'm wrong but you're seeing this symptom (temp rising followed by boil-over) several seconds AFTER boosting??
