Reply to "Carburetors with Annular Boosters"

George PAdmin.

QFT has "Super Street" vacuum secondary carbs with electric chokes in 4 sizes, 680, 735, 780, and 880 cfm.

Can you image a Blue Thunder manifold, exhaust heat blocked-off, with an 880 carb having annular boosters? A carb with the low rpm performance of a small carburetor, but the top end performance of the 880! With the annular boosters that carb would also be streetable on the Strip Dominator intake.

Carburetor boosters are perhaps the most important part of a carburetors performance, yet they are overlooked by most folks, and their functions are not understood. I realize now that I could provide more info about annular boosters, what they do, the various ways they can be employed. But not today, I'm not in the mood for composing something like that today.

Until then here's a link to some reading on the subject of Booster Venturis, an excerpt from David Vizard's book "How to Super Tune and Modify Holley Carburetors".
