Title: Raising fuel pump amps/voltage?
Post by: Carl on November 01, 2011, 03:44:35 PM
Does anyone know an easy way to raise the max amperage to the fuel pump without boost-a-pump?

My new Aeromotive 340lph is pretty power hungry.

260whp on 91 290 on E85 untuned.  Soon to be tuned on E85 with an hx35 and 1260cc injectors. Im stopping at 400 until i get new internals.

Btw this is with elevated fuel pressure too.

other than a parallel battery and tapping off for 24v, not sure of another way.
There are converters out there to get you to a higher voltage, that may help more than the amperage...if your FP motor will handle about 28v float voltage.

Just curious what does power hungry mean?? And what are you trying to accomplish??

thats what i was thinking,

How bout installin a relay in the trunk and run a large poer wire from the battry  to the relay and use the orginal wire
in the trunk to trigger the relay  that way you can run a larger feed wire to the pump. (make sure you up the ground wire also)

PS  Becarful with 400 RWHP on a stock bottom end 2.3 the rods are on the verge of breaking  (been there and done that)

 We were told the bottom end would handle 500  NOT
