Should I Tweak The Prop?

[sportster]

04 Rxp With X-charger, Rrfpr, 14/19, Cold Air Intake, 60*f Water, 70*f Air, 9.2 Psi Boost, 76.9 Mph, 2200 Ft Above Sea Level, 8150 Rpm.

Should I Tweak The Prop, Or Is 50 Rpm Over The Magic Number Ok?

Finally Got It In The Water, The Pull Is Incredible, The Sound Of The Shorty Box Is Perfect, The Sound Of The Supercharger From The Cold Air Induction Thru My Mirrors Is So Cool.

Not Sure If It Is The Intake Grate But When You Back Off The Throttle You Better Have Your Feet Braced, It's Like The Backshift On My Sled.

Thanks To Everyone On This Site For The Very Intuative Information & A Special Thanks To Gerry.

Congrats on the speed!

My advice is leave the impeller alone and get the Riva pro series nozzle and then run the 81 mm ring. That will drop your RPM's and also bring the speeds up higher.
