Speedmaster Billet Piston fuel pumps operate on a principle similar to a master cylinder, but with an ingenious floating O-ring valve function that continually adjusts to the amount of fuel needed by the engine. This is how Speedmaster Billet Piston fuel pumps can be used on any engine from 200-2,500 hp. Speedmaster's variable-stroke piston actually pumps less or more fuel as needed. Because of this variable flow, it doesn't need a bypass-type regulator or return line like traditional constant-pressure pumps do. Speedmaster fuel pumps' higher efficiency and variable flow mean that they don't have to work as hard as other pumps and don't add heat to the fuel like conventional diaphragm pumps. Speedmaster fuel pumps also consume less horsepower. The fuel pumps for carbureted engines require only 25 lbs. of pushrod pressure, compared to 125 lbs. of pressure for diaphragm pumps.You probably don't need the pressure and volume that Speedmaster fuel pumps can supply, but the extra capacity ensures that your engine will not stumble at the end of a straight because of fuel starvation. Regulators function more smoothly and consistently with the added pressure and flow. With a smoother supply of fuel, a Circle Track car will feel more predictable and pick up more smoothly out of the corners. The design also makes it easier to run fuel lines and the pump and fittings are less vulnerable in a crash. On top of all of that, Speedmaster Billet Piston fuel pumps just look cool!Valveless, Variable Displacement, Reciprocating Piston Fuel PumpSpeedmaster Billet Piston fuel pumps have been under development for 18 years. This is the first really new mechanical fuel pump design engineered just for high performance V8 engines in more than 60 years. All others are adaptations of an old universal design with many inherent pushrod/linkage design flaws. This simpler piston design is much more smooth and reliable at higher revs. Speedmaster Billet Piston fuel pumps flow enough for 2,500 hp! Features:* Reciprocating piston uses only 25 lbs. of pushrod force! The conventional diaphragm high performance pump requires 125 lbs.!* Operate at a constant 4 to 50 psi with Speedmaster pressure regulators, 60 psi unregulated* Absolutely no drop in fuel pressure throughout entire rpm range* Gasoline, methanol, and E85 compatible* Circle Track, drag racing, marine, and street use* Smaller size means increased chassis clearance. This is important in oval racing because the Chevy's pump placement makes it a target when contact is made with the wall.* Hard coated 6061-T6 billet aluminum with stainless steel internal parts* They weigh only 1.1 lbs. (Conventionals weighs 3.6 lbs.
