    Winter project


    I will be replacing the wear rings on my 09 230 challenger se w /510 hp over the winter. With one nicked the top speed is 58~ 60 mph on GPS. New I was getting 62 MPH on GPS. I am looking for more top end speed. Can anyone tell me what mods they done on this boat for speed increase? Impellers, 4” air filters…..
    Thanks

    4" Intakes will get you a few hundred RPM and are easy to do. What RPM's are you seeing now?

    That's what I was seeing prior to intake --- after I'm sitting right at 8020-8040, right where it needs to be.
