makes the GTX wheels seem kinda stop-gappy.

The lower inertia wheel along with the higher efficiency turbine wheel significantly improves the time to torque w/o affecting the rated power.

^^ i wonder if there are any numbers to quantify this time-to-torque marketing vs a conventional garrett. i'm not sure when we'll find out for sure if this is interesting or not. i'm assuming oem market and then sometime later aftermarket. if BW gets their **** together maybe sooner?
unfortunately i think probably not for a while. if its oem first, that means puny compressors. if the initial batch has one which can flow 350whp that might be interesting.

On a related note, double-stacked compressors is a pretty sweet idea, although I always thought turbos increased in efficiency as they grew larger due to tolerances dropping.
I'm not very excited about the titanium aluminide.
