I've got my parts together for building a hybrid GT4718/s400. Both the compressor and turbine wheels could use a diet. Looks like I should be able to trim 100+ grams from both of them combined by drilling the backside of the wheels.
I'd be doing this on my mill with a rotary table, so placement would be precise. Then I'd have them balanced independently, then combined.
Whose has done it, and how well did it work?
