my latest attempt at 3d printed boost, this time it looks like this should work . this version has no machining other than drilling and tapping holes . this is the first prototype of this design and will have an updated version in the future , successfully produced boost on a gx200 for a short period of time a larger than stock carb required when using a draw through system .( I haven't figured out exactly what carb yet)

rotors may require fitting to each other take material from the middle of the rotors not the outer edge .

requires 6x 608 bearings m4x16 (12pc)main body( inner set requires 16mm outer can be longer) m4x8(8pc)bearing cover m4x20 (4pc)shaft cross bolts m4x12(12pc) port adapter some 8mm shafting or tubing 3pc ( 2pc 103mm) (1pc 60mm or to fit your needs ) .

4560 stands for 45mm x 60mm rotors

currently using strait rotors .
