need info on hi-flow air box, and jetting , clutchng, for this sled, need to wake it up, in bone stock mode this thing is numb

I don't know all that much about the ZRT 600, but I would look at D&Ds website and even Black Magics. They both offer alternate air intake systems, clutch kits and more. If your looking at clutch kits Goodwin performance offers some really good performance gains with theirs. For other stuff like pipes and rejetting I would talk to D&D. Those are just my thoughts.

Trust me,do not use anything from BM.My 01600 zert had their clutch on it and i was very disappointed. Switched to an EPI clutch kit and dropped stock jets two sizes.Holy**** hang on! Providing you are studded that is. I have 144 and it could use a few more.The hiflow air box will actually rob horse power.Been on dyno and thats a fact jack!
