How much HP can GPH handle?
Horsepower A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500).
How many GPH is 800 hp?
Making the Choice
| Fuel Pump Free Flow | Carbureted Engine | Fuel Injected w/ Power Adder |
|---|---|---|
| 50 gph/190 lph | 600 hp | 400 hp |
| 67 gph/255 lph | 750 hp | 500 hp |
| 90 gph/340 lph | 1000 hp | 600 hp |
| 125 gph/470 lph | 1300 hp | 800 hp |
How much horsepower will a 340LPH fuel pump support?
1,000 HP
The AEM 340LPH High Flow In-Tank Fuel Pump (PN 50-1000) flows 340 lph (84 gph) at 40 PSI and is capable of supporting over 1,000 HP at 43 PSI.
How do you calculate horsepower from fuel flow?
- Converting Fuel into Horsepower.
- HP = TE x FUEL FLOW (PPH) x 19,000 (BTU per #) / 2545 (BTU per HP per Hour)
- Going back to our 300 HP example, TE = 0.1339 x 300 HP / 142 PPH = 0.283 (28.3 %) (Note that when using % in a calculation, you must divide the percentage number by 100.
- HP = TE x FUEL FLOW (GPH) x 44.2.
- Simple.
How much horsepower will a Holley blue pump support?
550 hp
The Holley Red pump flows 97 gph and supports 425 hp, while the Blue pump flows 110 gph and supports 550 hp.
How much horsepower is in a gallon of gas?
1 Gallon of fuel weighs approx 5.92 lbs and for every 1 lb of fuel burned approx 19,000 BTU’s of energy is released. So 24 gallons x 5.92 lbs = 142 pounds per hour to make 300 HP. If you burn 24 gallons of fuel per hour to make 300 HP, 142lbs/1 hour, you release 2,699,520 BTU’s of energy, (19,000x 142).
How much HP will a Holley black pump support?
The Holley Red pump flows 97 gph and supports 425 hp, while the Blue pump flows 110 gph and supports 550 hp. Stepping up to the Black pump yields 140 gph and 750 hp.
What is the blue fuel pump?
The BLUE fuel pump is a high-pressure fuel pump which operates at a free flow 110 GPH at a set pressure of 14PSI (0.96BAR). We recommend the use of a carburettor fuel regulator. This meets the flow high performance carburettor applications. This motor draws 2 amps current and an 8amp fuse is recommended.
How much fuel pressure does a Walbro 255 have?
The Walbro 255 liter per hour (LPH) high pressure (HP) fuel pump is the most popular in-tank fuel pump upgrade for the NSX. The pump flows 255 LPH of fuel at a base pressure of 43.5 PSI at 13.5 volts (an increase of approximately 65% over the factory pump).
What does GPH mean in fuel pumps?
gallons per hour
Another important factor is fuel flow. Fuel pumps are marketed with specific flow ratings—mechanical fuel pumps are rated in gallons per hour, or gph. Depending on your make and model, your Vette’s stock mechanical pump flows between 40-80 gph—the performance versions in this guide put out between 80 and 225 gph.
What kind of fuel pump do I need for EFI?
The 12-920 universal in-line fuel pump is intended for Throttle Body EFI, Multipoint EFI and Forced Induction Multipoint EFI systems. It is designed to work in-line, not inside the tank, so installation is a snap. The 12-920 is rated for continuous duty service and have been tested up to 2,500 hours.
What is the flow rate of a fuel pump?
Fuel Pumps are sized by flow rate. Flow rate is the amount of fuel a pump can supply over time. It is usually measured in gallons per hour (gph) or liters per hour (lph). How do I know what flow rate I need? Minimum flow rate needs can be calculated by multiplying peak horsepower by BSFC. This will give you fuel usage in lbs./hr. For example:
What voltage will increase the volume of a fuel pump?
To illustrate this, the A-1000 Aeromotive fuel pump at 80psi will see a 40% increase in volume when voltage is increased from 12v to 13.5v. This factor is often overlooked and can make or brake pump performance, especially at high pressures.
What percentage of fuel pump volume should be injected?
Many engine builders will add a percentage to total fuel pump volume for safety and then divide the minimum injector by .8 in order to target about 80% injector duty cycle. This allows consistent injector performance, cooler operation for enhanced durability and leaves about 10% for unexpected power.
