I can bet that after about 1min at full throttle it will blow. You cant go full throttle on a new engine. You can go in like 2-3 second spurts of full throttle but just going flat out full throttle off the bat will break a con rod. The heat cycle method is very quick and can be done in a day. If you are that impatient and cant wait then this hobby is not for you because you need all the patience in the world for break in.
