BVM does not have a bypass for the 3.5" turbine. He has a P60, P70 and a P80 bypass for the Bandit. I know I can use the P70 bypass for my turbine but it will not be optimized. I was told by BVM himself a few years ago that the bypass/pipe has a huge effect on his jet's performance, so I am assuming he did his homework on his bandit's bypasses...I also wanted to know the technical details of the bypass/turbine size!!!!
