    RPM difference between stock wheel and B1?

    Assuming I keep the prop the same how many rpms can be expected from swapping the stock wheel to the B1 with the R2 reflash?

    I am running B1 wheel with scat prop 14/23 and turning 8400 R2 reflash. With stock prop you will need to repitch in order to not turn to many rpm. Oldman

    Oldman is 100% correct you will see too many rpm's with the oem prop and a B1 and r2 for sure ,the oem will need to be re pitched to 15/22 or 15/23 and even then you will have plenty of r's Tommy Jordan

    On cold motor Im turning the repitched stocker 8360 and after heat soak 8240 with R2. What is the stock prop pitch to begin with?

    Where does the rpm range need to be with the B1? Is between 8300 and 8400 the sweet spot? Will anything less than that cost me speed due to boost loss?
