255lph rewire necessary with Evo316g?

[jlado13]

Okay, I've been reading, and I know that rewiring your fuel pump will create a lower voltage drop to your fuel pump and make it more consistant. But my question is, is it really necessary for running 18psi of boost on a turbo like the evo3 16g? I would think that the 255 should flow plenty of fuel for this setup, but then again, I am learning. Here is mainly what I'm going to be running.

stock 6 bolt block, 2g head
fic 650cc's
Aeromotive FPR
afc neo
greddy 24v fmic
and of course the logger

Thanks

I got some interesting information, I don't see a 255 on your list, so maybe you'll reconsider saving 100$

Got this info from DSMLink forum.

Wanting to making more HP, will your stock rewired pump meet you needs? The following was taken from www.conleyracing.com, it takes about
.6#/hr of fuel to make 1 HP for a turbo-charge engine. ie. 600HP x .6 = 360 #/hr = 60 GPH = 227 liters/hr or 40GPH(151 liters/hr) for 400 HP.

I believe the following numbers from the RRE site are base FP plus boost for stock pumps

1G@14v
43 psi = 132.5 liter/hr
58 psi = 100.3 liter/hr
73 psi = 55.52 liter/hr

2G@14v
43 psi = 156.47 liter/hr
58 psi = 113.23 liter/hr
73 psi = 88.33 liter/hr

Anybody got any related/different numbers than said?

eboy0 is correct, but if you intend to further upgrade you setup, a 255 would help, especially with 650s and 18ibs, and the 2g has a 7bolt stock unless swapped. At least rewiring your stock pump could help but i would definetly recomend the upgrade to the 255 or at least 190.

My question to you: Why wouldn't you rewire the fuel pump? It's cheap, easy, and provides peace of mind.

Sorry I forgot to list that. I already have the 255 installed... that's why i'm asking. if it will be MORE than enough, i would rather not pull the fuel pump out again to rewire it. But I gladly will if it is highly recommended.

i also am engineless right now i'm doing the 6bolt swap. should be here within two weeks


thanks

My 255HP has not been rewired and i've had no troubles with it keeping up with running up to 30PSI(falling back down to 25 at redline) on an EVOIII 16g.

I bet that feels good.


The pull you get I mean..

It hits extremely hard when I get under boost, but as far as how hard the turbo pulls throughout the powerband i'm not too happy. Hoping to upgrade to an FP30xx soon, this turbo just isn't enough for me

1. There is no need to pull the pump for re-wiring.

2. Fuel pump re-wire is helpful in any level.
