This is a lightly used Impeller (cold side) for all Rajay Model B-Flow and similar Turbochargers. The most popular application is the 1962 to 1964 Corvair Spyder engines. It has been cleaned and tested for trueness with no chips or other damage. The part number stamped on the bottom is still visible. The \"missing piece\" on the edge was how they were balanced, and this one shows very little modification.
This will not fit the later 1965+ F-Flow unit. Speed ofshipping is your choice at check out. Thanks for looking at this and my other Corvair turbochargers and carburetors and parts.
