I am a new member of this from and like to thank everyone for the wealth of knowledge I've learned about the GPR from reading this forum.
I have a 2000 GPR that I'm currently adding a 91 Octane GK 1390 BB kit to. My question is how much additional performance can be expected by adding the 05 pump/impeller combination and what impeller is recommeded? Can I buy the complete conversion kit anywhere?

WELCOME aboard! You can get the kit from IslandRacing.net or Green Hulk.net we have seen 2mph gains with the setup.

Welcome.The speed gain with the dynafly pitched to a 15-24 to a 15-25 is around a 1.5 to 2mph gain. I would start my pitch somewhere in that range to start off. watch your rpms. Do you have a pet-tach?
