Razer ran a Radial piston pump rated at 10,000psi powered by a 6v motorbike starter motor ran at 12v, so i agree it was a powerfull motor, Razer never revealed its gearing ratio which always lead to some sceptisum as to the psi they were producing, when i personally asked Vinny at an event (i think it was Debenham 03) i asked what pressure it ran at he smiled and said 3000 of course, when i asked again he said might be over but they dont check do they

thus leading to my conclusion of them running a higher pressure, i stand by my beleif that they over ran there psi i dont think they ran 10,000psi but i do think they ran higher than 3000

No i have no evidence other than my convo with vinny which is speculative at best but the fact they didnt enter when they intorduced the pressure test and the fact they never told anyone there gear ratio
No its not hard eveidence but i stand by my comment
