which one is FASTER?? let see with an onroad comparison. 3rd gear, 50- topspeed dynamic test. 0:00 intro / 0:04 polinibox SOUND / 0:17 w1r torque+ / 0:34 polinibox / 0:52 both / 1:17 diagramm / 1:21 clutch slipping / 1:51 QUIET polinibox / 2:14 polinibox SOUND / 2:35 w1r troque+ SOUND / 2:56 t5 auspuff SOUND /

exhausts: w1r torque+ / polini original box

setup: quattrini m1x, reed valve, phbhe 34, 60mm longstroke = 180cc

clutch: even though new springs, they are too weak. as engine got a bit FMPimped ;)
slipping comes earlier and is a bit stronger with polinibox = small advantage powerwise is my guess


conclusion: with this setup, they are exactly the same, i see a tiny advantage on polinibox side

a bigger one regarding sound / noise, polinibox is unbeatable the most quiet box available.
