Stu @ M Developments,
It pisses me off everytime i see a nice new shiny and expensive breather on the market that has say.. for arguments sake... 4 nice 16mm intake ports, perhaps 2 for crankcase and 2 for camcover.. great eh? 4x the std breather outlets
It also has an oil return.. brilliant, should save a little on oil consumption/loss...
Finally it also has a 1x 16mm or slightly larger return to atmosphere/airbox for the relieved sump pressure...
Erm... who can tell me whats wrong with this design?
4 x 16mm engine outlets - total effective engine outlet size to breather tank = 64mm
only outlet to atmosphere from breather catch tank is still 16mm - hence you havent then breathed anything more than what the std engine had
