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 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
