Anything that increases the Brade Mean Effectibe Presure (BMEP) on the piston of an internal combustion engine (that will give an increase in torque at any given RPM, which will give more horsepower at that RPM) will cause the pressure the piston excerts against the cylinder wall opposite the crank pin to increase. That will lead to more wear on the liner on that side. Thats exactly what the first liner on my grandsons DTX 18 looked like when we had to replace it. Anything that increases the power of an engine will cause it to wear quicker, if that power is used constantly, whether that engine is in a model car or a full sized car. In some respects an engine is an engine and size doesn't matter.
