1. There is no reason an engine should be damaged simply by applying full throttle.
2. You may wish to do some research on what you call torque and the tail wheel locking of a p51.
3. If you don't want to go look up performance DATA. Then your simply speaking out an orifice.

1. On a small engine like on a Cessna or a Vans RV, that would be true. But there is a reason why takeoff manifold pressure is less than full on large, high horsepower engines. the P-51 takes off with 40" to 45" manifold pressure. Operation at extreme manifold pressures like 60" should only be accomplished in flight for short periods of time and for emergencies only. Going straight to full power in a plane like the P-51 from idle on the ground would cause huge stress due the rapid onset of power and inadequate cooling due to low airspeed.
2. I am aware of the tail wheel lock and how it works. Believe it or not, that is necessary knowledge to be able to take off in DCS, but if you think a couple square inches of rubber is going to keep all that airplane straight, you are sorely mistaken.
3. My fingers typing on my keyboard isn't an orifice, unless you count the sweat glands.
