Large volumes of gasoline are distributed evenly to each cylinder by the PERRIN Top Feed Fuel Rails. Consumers will notice the car runs smoother and is more powerful when large injectors are used, and tuners can safely push the engine closer to the limit. For optimal fuel flow, PERRIN High-Flow Fuel Rails include large interior diameter channels. Cars may now operate at 800 WHP without experiencing fluctuating fuel delivery to each cylinder. To ensure a proper connection to the hose, we supply specially manufactured -6 barbed fittings with O-rings. Because these fittings are detachable, aftermarket fuel lines can be easily customized.
Your high-powered Subaru may produce more power while being safer thanks to the equal-flowing nature of PERRIN fuel rails. A requirement for any vehicle aiming for 400 horsepower or more. To ensure that all cylinders receive an equal distribution of fuel, pressure, and air/fuel ratio, PERRIN High-Flow Gasoline Rails partition the incoming fuel. The factory-installed fuel rails distribute fuel to each injector in turn as it passes through the engine compartment. This significantly decreases fuel supply to the final injector in line with modified Subarus. The 6061 billet aluminum fuel rails and distribution block for the PERRIN engine are precisely CNC machined. Each -6 Barbed Fitting is easily customizable for aftermarket gasoline lines thanks to its detachability from the distribution block and rails.
A built-in phenolic spacer is included with every PERRIN High-Flow Fuel Rail. Fuel rails and junction blocks are installed with spacers that are placed between them and the engine to insulate it from heat. As a result, fuel remains more closely at room temperature. Contrarily, without these spacers, fuel temperatures can be shown to rise by much higher than 30 degrees above ambient. Large 3/8" inner diameter fuel injection hoses on PERRIN fuel rails enable them to deliver higher flow rates than competing systems. This hose has a capacity of more than 800 WHP. A rubber fuel injection hose with the appropriate liners for zero emissions is part of the package. The rubber used to make the hose has the added benefit of helping to attenuate pressure waves, which results in smoother and more stable fuel pressure. Perrin Flexguard is woven ballistic nylon with a high abrasion strength and heat resistance that helps prevent hose damage during vehicle operation. designed with a heat- and flame-resistant coating for use in applications up to 260 degrees Fahrenheit continuously. Race cars all over the world utilize hose covers of this design.
Also, the Oetiker clamps are included with PERRIN High-Flow Fuel Rails. Oetiker clamps provide a tight fit because there are no gaps in the band, which improves the seal; unlike conventional worm drive clamps, their clamping mechanism won't corrode with time. With just one squeeze of the Oetiker crimping tool, they are also significantly simpler to install.
