Unless you widen the openings from the center section, it will never breathe like a 15.5 or 16.
comes close just by changing dsv and hoses:-MK15= 2.29J/L compared to 1.97J/L for MK15.5
@45m and 75 RMV
Mk15 w/standard Hoses and scott mouthpiece 5.3J/L
Mk15 w/redar(cooper style) Hoses and scott mouthpiece 4.1J/L
Mk15 w/AGA ACSC mouthpiece and hoses 2.44J/L
MK15 w/rexnord mouthpiece and mk16 hoses 2.29J/L
MK15.5 w/Rexnord mouthpiece and MK16 hoses 1.97J/L\
Im currently rebuilding my MK15.5 with Boris hoses and Boris DSV.....hoping that will beat even 1.97
