A 255lph pump delivers about 410lb of fuel per hour so that’s enough to feed about
750 crank hp
with forced induction (assuming 0.55 BSFC) and 900 crank hp NA (assuming 0.45 BSFC).

How much HP is a Walbro 255 good for?
The Walbro 255hp can support
up to 760 crank Horsepower at 17.5 volts
. This level of voltage can only be attained by way of a “Boost a Pump”. This is also dependent on Fuel pressure/Boost Pressure/ Other Factors..etc.. On a car equiped without a Boost a pump (around 13.5 volts) it will only support about 500whp.
How many LPH is 1000hp?

Do I need a tune for Walbro 255?
Do you
NEED to tune the car, no not at all
. Keep in mind here guys that you still have certain mechanical constraints on the system. The lines are the same, the FPR is the same, and the rail are the same so the volume and pressure are still basically the same.
How much HP will a Walbro 450 support?

How many GPH is a 700 hp?
Theoretically, the mechanical pump could provide the (approx) 60 gallons per hour that the engine would need, using the formula of 1/2 lb of fuel per horsepower per hour. That’s if you used a quality mechanical pump and not a stocker. So, 700 x . 5 =
350 gal
.
Do fuel pumps add horsepower?
Horsepower
As horsepower increases so does the volume of fuel required to support that power
. 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 much fuel is in a horsepower?
On average, an in-tune four-stroke gasoline engine will burn about
0.50 pounds of fuel per hour
for each unit of horsepower.
Does a new fuel pump require a tune?
Yes, you will need a new tune
becuase you will be running rich since the new pump will flow more fuel. Yes, you will need a new tune becuase you will be running rich since the new pump will flow more fuel.
Do you need a tune for bigger fuel pump?
It will run just swapping pumps but
might need a re tune
. The bigger pump freaks out the FRPS and causes high fuel pressure spikes and hesitations on shifts. I had to re tune mine going from the stock to a 255 SVT pump.
Does a WRX fuel pump need a tune?
It can also result in more stable fuel pressure due to higher flow limit. So in answer to your question.
No. A tune is not required and you will not run rich
.
