The 190lph pump flow numbers are finally out. http://www.autoperformanceengineerin....html#overview

It looks like it flows about the same amount of fuel until 90psi, but it's nothing close to the 255lph. I don't know much about the gph needs of our car, but using his HP calculation at 90psi the 190lph HP can only support 228hp whereas the 255lph HP can support 324hp.

I was hoping the 190lph HP was a better performer, but I guess it's not Now my question is how many of you are running without a FPR?

We all still have the FPR except those who have the fancy adjustable Vortech FMU or Cartech FMU that also can set a baseline fuel pressure.

 

The baseline FP is what I'm interested in. I'll probably go ahead and get the Walbro anyway and deal with a new FPR later on.
