What advantage is there?

CB Performance Flanged Crankshaft, what is the advantage? What are the down falls? Today we will discuss both of those topics.

A proper bolted connection needs to have a very stiff joint (flywheel/crank) and springy bolts. The stock VW gland nut and dowels is the opposite. This is why type IVs and 911s have conventional bolts. The VW industry should have just switched over to that as an intermediate to the full on drag large flange. The Scat flange is better than the CB since it has more bolts instead of a lot of pins. The pins aren't what is keeping the flywheel on the crank. It's preload and friction.

165 HP? You still have a lot to learn. 321HP turbo street here. Learned the hard way by try every other method. Even a RLR Rev 6 to soften shock of launching. FLANGE IS KING. As well as the bearings.
