Nissan has a different take on solving this problem by having variable compression on their new VC-T engines that were on here a few weeks ago. That approach is nice because you don't have to fill any reservoirs and can still get high compression ratios when not running under turbo boost thus increasing efficiency. I really want to see where that one goes, and it is actually in a production car I think this coming year.
