What to Look For in the Best Aeromotive Fuel Pumps for Nitrous Systems
When you are building a nitrous system, your fuel pump is not a part you want to guess on. It is the heart of your fuel system, and a weak heart means a weak run, or worse, a damaged engine. I have learned that picking the right Aeromotive fuel pump comes down to a few key things that go beyond just looking at the biggest number on the box.
First, you need to think about flow rate, but you have to be smart about it. It is not just about the maximum flow; it is about the flow at the pressure you will actually be running. Nitrous systems put a massive, sudden demand on your fuel system. Your pump has to be able to maintain both your base fuel pressure for the engine and the additional pressure required to feed the nitrous solenoid without dropping off. A pump that flows 340 liters per hour (LPH) at 45 psi might only flow 240 LPH at the 70-80 psi your nitrous system might need. Always check the pump’s performance chart to see its flow at your target system pressure.
Next, consider voltage. This is a big one that many people overlook. The voltage at your pump is almost always less than the 13.5 to 14 volts your alternator puts out. There is a drop through the wiring, relays, and connections. A pump rated at 1000 horsepower at 13.5 volts might only support 800 horsepower at 12 volts. I always plan for this by choosing a pump rated for more than my goal, and I make sure to use a high-quality relay and thick enough wiring to minimize that voltage drop. A dedicated, robust wiring kit is a non-negotiable part of the install.
Finally, think about the type of pump and how it fits your setup. Are you running a carburetor or fuel injection? This determines if you need a high-pressure EFI pump or a high-volume carburetor pump. Also, consider if an in-tank or an external inline pump is better for your car. In-tank pumps are generally quieter and benefit from being submerged in fuel, which keeps them cool. External pumps are often easier to service and can be a good solution for vehicles where an in-tank unit is difficult to fit. For a serious nitrous application, you might even see people using multiple pumps or a large main pump with a dedicated, smaller pump just for the nitrous system. Do not just pick a pump; design a fuel system that can handle the shock of the nitrous hit.
FAQ
Can I use my stock fuel pump with a nitrous system?
In almost every case, no. Your stock fuel pump is designed to support the engine in a naturally aspirated state. When you activate a nitrous system, you are dramatically increasing the engine’s demand for fuel almost instantly. A stock pump simply cannot keep up with this sudden surge, which will cause a lean condition. A lean condition under the high cylinder pressures created by nitrous is a surefire way to cause severe engine damage. Upgrading to one of the best Aeromotive fuel pumps for nitrous systems is a mandatory safety measure, not an optional upgrade.
How do I know what size Aeromotive fuel pump I need?
You need to calculate your total fuel requirement. Start with the fuel needs of your engine without nitrous, then add the fuel required for your nitrous shot. A common rule of thumb is that you need approximately 0.10 to 0.125 pounds of fuel per horsepower per hour. So, for a 500 horsepower engine with a 150-horsepower nitrous shot, you would need fuel for 650 horsepower. That is 650 hp x 0.10 lbs/hp/hr = 65 lbs/hr. Since there are roughly 6.5 pounds in a gallon of gasoline, this translates to about 10 gallons per hour (GPH), or roughly 38 liters per hour (LPH). This is a simplified calculation, and you must also ensure the pump can deliver this flow at your specific operating fuel pressure, which is why looking at the pump’s performance chart is so important.
What is the difference between an in-tank and an external fuel pump for nitrous?
In-tank pumps are mounted inside your fuel tank. The main benefits are that they are quieter and use the fuel in the tank to keep themselves cool, which improves their longevity and consistency. External pumps are mounted in-line, somewhere along the fuel line between the tank and the engine. They are often easier to access for service or replacement. For high-horsepower nitrous applications, many builders prefer in-tank setups for their cooling benefits, but robust external pumps like the A1000 are extremely popular and proven. The best choice often depends on your vehicle’s layout and your personal preference for installation and maintenance.
Do I need a fuel pressure regulator with an Aeromotive pump for nitrous?
Yes, absolutely. A high-quality fuel pressure regulator is a critical component. It does not just set your base fuel pressure; it must be able to react quickly and maintain a consistent pressure when the nitrous system activates. A good regulator, like many of Aeromotive’s own models, will have a large diaphragm and be designed to handle the rapid changes in flow demand. For nitrous systems, you often need to reference boost or nitrous pressure to the regulator to ensure the fuel pressure to the nitrous solenoid rises appropriately, maintaining the correct fuel-to-nitrous ratio.
Should I run a dedicated fuel pump for my nitrous system?
This is a popular and very effective strategy, especially for larger nitrous shots. Instead of asking one pump to do everything, you use your main pump to supply the engine and a separate, smaller pump dedicated solely to feeding the nitrous system. This isolates the systems and ensures that the nitrous system always gets the fuel volume and pressure it needs the moment it is activated, without robbing fuel from the engine. This is considered a best practice for high-performance and racing applications where reliability is key.
