High-Capacity Fuel Rails
D-Rails Provide Fuel Injected Engines With Fine Fuel Metering, More Flow and Capacity to All Cylinders
Wilson Manifolds’ new D-fuel rails are designed to provide three important advantages for all competition fuel injected engines: fine fuel-metering, more flow, and more capacity.
Often, injectors and cylinders are robbed of fuel as it rushes past the injector ports in the fuel rails, and in some instances fuel is actually siphoned out of the injector ports. This threat is not only discernible in Pro Mod cars and Bonneville cars and vehicles with twin turbos and twin injectors but also can be a severe impediment in all competition fuel injected race engines.
To overcome unequal fuel distribution, Wilson’s new D-rails, which have 50 percent greater capacity than any other, employ radiused inlet injector ports (see accompanying illustration with cross-sectional view) and carefully position each injector below the port. This technique reduces the harmful effects of siphoning, especially at the injector ports placed at the beginning of the fuel paths. By increasing the capacity of the fuel rails, radiusing the injector inlet ports, and placing the injectors in their submerged locations, the adverse effects of pulsations and siphoning are greatly reduced. In addition fuel distribution is improved and engine power is increased.
When GM, Pontiac, BMW, and Porsche installed Wilson’s D-rails in their various Daytona Prototype race engines, allwithout exceptionexperienced power gains.
