as titile states.. please help!!!

Will a sard fuel pressure regulator be sufficient or do I need to upgrade pump as well????

 

No you need bigger injectors with higher flow rate/min.

 

ok so what will the fpr do for the car????

If this is true what you are saying then I'll just get them flowed!

 

Think of a garden hose with a sprayer on the end. Imagine the sprayer has a very small hole in it. Now increase the pressure in the hose - what happens? Do you get a <u>lot more</u> water coming through the hose?? NO - but the spray will be a lot finer due to the increased pressure and you also end up stressing the hose.

Injectors run at too high duty cycle can fail - which means motor go boom!

Bigger injectors are like increasing the size of the hole at the sprayer end. A fuel pressure regulator/riser increases the pressure of the fuel.

when you increase the flow rate of the injectors you can overwhelm the ability of the stock fuel pump to keep up with the extra fuel demands. On cars that have really high fuel needs - a bigger fuel pump is also recommended.

 

awesome.. nice to know that i have enlightenment for today!!!
