u deff can hit 400+ dpeneding on how much boost u run, its not alwyas a good idea to replace the bearings, if they dont have much copper showing then i would leave them in, in some cases its worse to run new bearigns then to reuse them.



that is the exact same turbine i have sittign on the shelf waitign to go on my FD and my goal is 450+ at wheels, so well c soon what i get.
