I'm looking at options for upgrading the fuel system so I make sure I don't run out of pump on the dyno. Currently running a rewired 450
I'm on E85 will be with ID2000s shooting for 700hp.

This is on an 05 so I have a return system. Im trying to keep this as simple as possible.
I was thinking, Is it possible or had anyone here ran a stock fuel hanger and ran an external bosch 044 to the stock fuel rail?

There brushless pumps coming out with various manufacturers but im unsure of anyone who has tried them

Hatrickstu has one, aeromotive I believe, not sure which model.

I didnt know brushless pumps were a thing now. $1000 for a pump..good god. They have a single drop in pump that supports 2700hp on FI!!! Wtf

dual 450s

some say it supports 700 and others say they ran out of pump in the 600s. There is no reason to cut it close as I don't want to take any chances. Dyno time is a lot more expensive.

safe 600 Once over 650 it depends on injectors and pressure your trying to achieve. I was knocking on 700 when mine started lossing pressure at higher duty cycles with my 2200s.... it actually did better on the 1650s because it did not have to work as hard... but i quickly maxed the 1650s out.

Now dual staged 450s and 2200s.... got all the fuel in the world hoping good for 950-1000

There are two different 450 pumps. One supports about 85psi max and the other supports about 120psi max I believe and is about $10 more. Make sure you get the 120psi unit, just can't remember what part number it is.

This is true... and defiantly for the single guys want the 120, but when you run dual, no longer need crazy pressure when u got FLOOOWWW
