Stanadyne’s Goliath Performance GDI Pump

The Stanadyne Goliath performance pump is a high-quality, modular solution addressing the fuel flow limiting factors of stock mechanical fuel pumps when trying to increase the power output of GDI engines.

Stanadyne, a global fuel and air management systems supplier, is expanding its performance and specialty product portfolio with the launch of its patented Goliath high-flow, 12mm bore, up to 350-bar performance gasoline direct injection (GDI) fuel pump. The company announced the new performance product at the 2023 PRI Show in Indianapolis.

The Stanadyne Goliath performance pump is a high-quality, modular solution addressing the fuel flow limiting factors of stock mechanical fuel pumps when trying to increase the power output of GDI engines. It is purposefully engineered for specialty and performance engine enhancement. Its modular design and connection-ready inlet fuel line fittings make installation safer and easier for both professional and amateur tuners. Their proven performance is built on providing more than 9 million GDI fuel pumps to an original equipment manufacturer (OEM) to support its small block engine platform.

The Goliath pump increases fuel flow by an average range of 83 percent, compared to factory-installed stock GDI fuel pumps with 10 mm plunger bore size. Its 12-mm plunge bore size, compared to the standard 10 mm, provides up to 2cc of fuel per revolution at a 6mm stroke at up to 350 bar of fuel pressure. This specialty engineering pump can deliver up to 2.8cc of fuel per revolution. This industry leading fuel flow is delivered at a custom 8mm stroke without the plunger losing contact with the camshaft/lifter when the engine is operating at 6,000 to 6,600 rpm.

Stanadyne’ s OEM production expertise, processes and best practices are applied to its aftermarket products. The Goliath performance pump is modified during the build stage – as opposed to after final assembly – to mitigate contamination concerns. Pumps are fully laser welded in a clean room environment and helium mass leak tested for unparalleled commitments to product quality and safe operation.

The Goliath pump is custom made to precisely fit a variety of engines without the need for complicated adapters and risky plunger extension buttons. The pump has Stanadyne patented plunger, which significantly improves engine safety and operation when compared to currently available modified aftermarket pumps.

The Stanadyne purpose-built high-flow, high-performance Goliath GDI fuel pump covers a range of horsepower applications for a variety of engine makes, such as Audi, Aston Martin Vantage, BMW, Ferrari, Ford, GM, Infinity, Kia, Lamborghini, Mercedes Benz, Stellantis, and Toyota. It currently is available through select Stanadyne Performance partners.

Stanadyne is the flexible performance enhancement partner of choice for tuning, racing, and specialty vehicles. High-performance and specialty tuning and racing vehicle retailers and distributors interested in using the Goliath for their fuel system tuning kits should reach out to the company through the Contact Us page or emailing [email protected].
