to much fuel will cause to much stress on the rod and crank i used to do a method very similar to that and it sucks it stresses out the engine way to much and reduces the life alot you want to run it at 200-220 cold metal rubbing on cold metal with alot of stress is not at all breaking in an engine
by the way 16 hours of racing is not that much i do that in 2 months if you break in the v-spec the right way you can get 7-8 gallons out of it
