How is this possible, 13/22r & 13/24 ST
I am big time confused at the moment, yesterday we went to test a friend's FZR that has a C5, R3 & Skat Trak 13/24 ....
77.3@8060 .... very good speed comparing to the rpm, so what I need to do is push the rpm upto 8400-8500 to reach 80mph ...
then tested it with a Solas 13/22r ... 77.3@8120 ...
tests were done back to back with the same jocky (me) ...
How is this possible? only an extra 60 rpm is the difference switching these impellers made?
couple of weeks ago I was testing FX Sho with E1 and 13/22r, 80.3@8650 (R2 limiter) ... changed the impeller to Skat Trak 13/24 ... 79.7@8650 ... then tried a Skat Trak 13/25 79.5@8400 ... weird right? ....
It seems that the Solas 13/22r does not follow the common impeller pitch/rpm law that i experience with Skat Trak ...
Any similar cases?
