This mod can't be compared to the LWFW. The LWFW won't add steady state tested HP because it only reduces mass. The UD pulley increases HP by slowing down the accessories of the engine.

JFP, the boss extends into the case, so after removing the 12mm necessary for clearance enough of the boss remains to be useful during cam timing and engine maintenance.
