lightened / balanced / knife edge crank

[Mathias]

had a search but cant find much, what are the advantages of this?

bearing in mind it will be used on a turbocharged engine, im using a billet lightweight flywheel anyway, i can imagine this being great on a high spec na screamer of an engine but what effect will it have on a turbocharged setup?

ive seen his, however he's running a high spec n/a engine

the knife edge helps it cut thru the oil in the sump better, causing less drag and thus fewer losses.

of course it will also be lighter so once again reducing the rotating mass weight, how much you would reduce the losses by im not sure
