QJets have a maximum airflow of from 750-800 cfm. Because the secondary side of the Qjet opens according to the airflow requirements of the engine, the same basic carburetor size can be used on a large range of engine sizes. The basic 750 cfm QJet casting is used from 231 CID to over 400 CID - the big secondary air valves open only as the engine breathes. For example, on a mild 350 Chevy the air valve will never open all the way - because the motor can't use more than 600 cfm or so.
also, ein 750cfm Q-Jet kann es schon. Ich denke GM und die anderen großen Hersteller haben die Dinger nicht aus Jux vom 231er bis 400er Motor millionenfach draufgebaut.
