Trying to see wich one flows more and is better for my 2.8.I was told a 044 but how do these 2 compare

WALBRO 190LPH 190 External FUEL PUMP GSL391 GSL-391 Inline MADE IN USA


OR



Porsche 944 Turbo, Fuel Pump Bosch 0.580.254.942

Thank you guys

pole position

The Bosch will flow more especially at higher rail pressure and is generally more reliable. However , if you decide on a Walbro go for the 450

Im using a 3 bar fpr also will this support 450ish wheel the bosch? How does it compare to the 044 ?

You want to look at the GSL 392 pump from Walbro

The 450 only comes as an in-tank pump I thought? I'm pretty sure the 255s are the largest external pumps they sell, which I have on my car, but I haven't driven the car in years and it was just a stock S so I was no where near the limit.

If you can afford it, get the Bosch, if you want to save a few pennies get the Walbro. Refresh951 has the Bosch on his 3.15L build and I think he just now hit the limit at around 490whp (though there could be other factors involved in that too, like too small plumping etc.)

JBrown

So the Bosch I stated in my 1st post ?

refresh951

Will you be running E85?

JBrown

Going to run 93 on one tune and. Meth injection on other

580.254.044 will work great and leave some head room for future upgrades on 93. Make sure it is not a chinese "knock-off" I would buy it from here:

Great price ($180) and it will be a legit 044 pump.

Jay racing also makes an 044 upgrade pump that has a great reputation in the turbo forums but they are sold out at the present time. Rogue told me about these guys.
