The double pumper mechanical secondary design feeds both venturis the moment the throttle opens, so response stays sharp on track and off. It suits racers, engine builders, and gearheads running a built small block or big block that needs serious airflow.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e850CFM airflow rating supports high-horsepower, high-rpm V8 combinations\u003c\/li\u003e\n\u003cli\u003eDouble pumper mechanical secondaries open both barrels together for instant fuel delivery\u003c\/li\u003e\n\u003cli\u003eMechanical choke and throttle linkage keep operation fully manual and predictable\u003c\/li\u003e\n\u003cli\u003eFour barrel body with dual accelerator pumps feeds fuel on sudden throttle input\u003c\/li\u003e\n\u003cli\u003eAluminum construction keeps weight low while resisting heat soak\u003c\/li\u003e\n\u003cli\u003eBR-67201 reference number allows direct comparison against OEM cross listings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBR-67201\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBarrel Count\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 barrel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAirflow Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e850CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSecondary Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMechanical, double pumper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChoke Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMechanical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDrag strip and circle track builds chasing maximum airflow\u003c\/li\u003e\n\u003cli\u003eModified street machines with aggressive cam and intake packages\u003c\/li\u003e\n\u003cli\u003eMarine and off-road V8 applications needing instant throttle response\u003c\/li\u003e\n\u003cli\u003eEngine dyno testing and tuning sessions with wide open throttle pulls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What makes a double pumper different from a vacuum secondary carburetor? \u003cstrong\u003eA:\u003c\/strong\u003e A double pumper uses mechanical linkage so the secondaries open on throttle input rather than waiting for engine vacuum, which gives faster response on built engines. It usually wants more tuning attention but rewards that with sharper acceleration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Is 850CFM too much for a mild engine? \u003cstrong\u003eA:\u003c\/strong\u003e An 850CFM 4 barrel performance race carburetor generally suits engines with healthy displacement, head work, and cam duration.
