I got to say I'm pretty skeptical of anyone getting away with that much boost on top of that much compression.
Compression + boost has its limits no matter what the piston geometry or chamber design is like.
Nope, its doable and can be realiable. As long as your air/fuel mixture is correct, anything is possible. Hint, Hint .....engine management.Hell, I've seen B-series motor running 12.5 comp or higher on pump gas.
