Also notice the furnace brazed impeller and turbine fins and inner blade support. ATI manufactures each part of their converters to handle the rigors of drag racing, and doesn’t use any OE parts like some other converter companies. Each ATI converter is custom configured for the specific application to ensure proper performance.
