A wedged float is a necessity for the circle racer. The wedge is designed so that when you are in a turn, and the fuel has sloshed up the side of the bowl, the fuel will ride up the wedge and allow the float to stay open and not close off prematurely. Holley's wedged floats also feature a reinforced float bracket assembly that allows more fuel to flow thru the bracket especially when using a bottom feed needle and seat. Made from Nitrophyl, the new Holley wedged floats weigh in at approximately 12. 8 to 13. 2 grams and are available as a primary float, secondary float with notches for jet extensions and a secondary float with notches that includes the jet extensions. Nitrophyl is a registered trademark of the Rogers Corporation.
