true, but for a 800+bph 1.8 it might be wiser to start with 7:1.
Don't be shocked, the engine WILL run fine at such compression, it will just be a tad gutless while off-boost (it depends on the ignition timing as well)

You'd need specially made pistons for sure, with thicker crowns and a repositioned top ringland perhaps.
That would be the first deterrent against detonation. We're talking several bar boost pressure here.
