WebJun 8, 2024 · Holley also notes that, at high engine speeds, the air/fuel mixture must be on the rich side in order to prevent engine carnage (high speed lean out). When it comes to the idle air bleeds, keep in mind the idle system provides fuel at idle and low engine speeds. Under these conditions, the engine requires a richer fuel mixture than it does at ... WebDec 10, 2024 · It is a normally open bypass valve that closes with pressure. Note: Most conventional fuel injection bypass valves are normally closed and open with pressure, such as for a high speed lean-out function. This alternative is used as an added bypass valve commonly in circle racing with fuel injection.
