Help With Impeller Choice
Here is a list of my mods:
RR new program ECU
Water box mod
OPAS Block offs
Exhaust cross over pipe
2.5 degree pump wedge
Riva supercharger impeller
R&D cold air intake
14/19 Solas custom pitch prop
Soon to have new RR Supercharger Impeller & 42Lbs Injectors.
Currently running 8500-8550 RPM
I know this is too high and wondering what your guys suggestions
are. Should I go with more custom pitch on the 14/19 or just put in the

I would step up to the 15-20 and work with it instead of the 14-19.
How do you like the New RRECU? I am gonna buy one I think???
What are your speeds?

Never ran it with a GPS but the speedo reads 75mph. Before I got the computer redone it was hitting 8350 RPM but now its 8500-8550. Gotta take it easy and get the right impeller. Oh I also did the exhaust cross over pipe at the same time. It just replaces the rubber hose comming off the water box. I stronly recommend the new RR ECU!!!
