22 of the most popular intank fuel pumps tested!
Massive fuel pump test of the popular intank fuel pumps by an independent company.
Spoiler alert.. Walbro 525 is a serious pump for those who need it and can supply it with proper voltage.

Effective enough comparison, becomes a useful reference point. Well done to Real Street for putting down the effort to produce these results.
This is nothing new to me though, I've been experimenting with fuel system, pumps, injectors, fpr, voltage for many years. It is also well known that by increasing base pressure UP TO A CERTAIN POINT, stresses the pump more but forces more fuel through the injectors, until the point of course the certain advantage the increased base pressure gives to the injectors is canceled out by the increased drop of flow.
To find the right compromise between forcing more fuel/flow through the injectors, by increasing base pressure, before pump flow starts to drop off too much:
Use the above fuel pump info in relation to something like this :

Make sure the voltage to pump/s is the right one for the demands of your setup and the fuel system/pump configuration you are running.
Through my experimentation, in regards to the evo, I've found that an upgraded intank pump with a "bigger" inline pump configuration is better than two in tank pumps, or one "big" in tank fuel pump.
* Remember this, you will push more fuel through the injectors and into the cylinders on the right effective pressure and slightly reduced pump flow, than on max pump flow but on the wrong effective pressure.

" If your goal is 300hp, then you need a big enough fuel pump to provide you with 300hp worth of whatever fuel you are using."
Try telling that to all the "I need a quadruple pumper setup on my stock turbo car because I think ,one day, that I'll be pushing 1,000hp" guys.
"I'd rather go big now, so I have room to grow"
LOL

Indeed, does seem low. My guess is has to do with the pressure relief valve. I used to have the good old 255 in my car with my BBK Full around 30# so call it 70# of fuel pressure which probably produced somewhere around the 450whp mark. That being said, I did perform the pressure relief mod on it which involved a quick tap with a punch to preload the spring so perhaps that's why it was successful in my case?
