If you would like to send a design to be tested; physical low value item that doesn't have to be returned. I dont own a 3d printer.

Dimensions Are:
Option A:
inlet - 54mm id
inlet - 60mm od - can be slightly bigger / smaller long as i can get a the silicone joiner over them,
75mm long - to keep test fair keep within 5mm. remember a big bell mouth or aggressive taper will act like shorter runner
87.5mm throttle spacing (centre to centre) - if want to run big bell mouths will need to be cut into each other.

Option B:
Same as option A but full length - 185mm & 52mm id

Option C:
Same as option A but any length between 30mm & 205mm. 52mm or smaller id will be tested at your length & diameter
