What would you consider 'stupid power'? 650 on the ground is 720-750 at the flywheel. You're probably going to have learn to live with frequent repairs or a bit less power.

Turbine speed has nothing to do with early VG failures - They are usually caused by excess heat.

We have been able to keep the heat down. Our pyrometer is post turbo and stays under 1,000 degrees but with minimal power added we have been over speeding the compressor wheel. That’s why we are loosing the turbos. I’m assuming it’s not the vgt or actuator that’s failing but the turbos are having to be replaced.
