What you see above is over kill but a rewire is not a bad idea. if you have a 255 high flow and the proper size injectors it is not realy needed. When i rewired my car i did notice the volts went up almost 2 at the pump. But if you are getting the fuel you need then i wouldnt worry about it. I dont know how hard it is to do on a 2g. A 1g AWD takes no time at all.

 

I don't think saying "Why im better than you" is going to get you many friends

 

I didn't rewire my 255hp when I installed it, I don't want to. I'm probably running on the edge of too much fuel for my near stock beast as it is. At idle, there is a much more pronounced fuel smell to the exhaust than there used to be, I may be running rich down low. Even with my planned eventual 16g/550 setup, from what I've read I don't think a rewire would be necessary or even beneficial.

 

i dont think bashing every 2gnt is gonna get ya many friends either jfwy

stock wiring is good for so long, when you get into the big turbo's, it becomes a plus, but then again, for a bigger turbo, i'd rather use an aeromotive external, but whatever floats your boat

 

well... some news for you:

1. I dont think i care
2. Its a joke Howdy... you know what jokes are right? Did you not see the last part of the How-To?

Did you just happen to blank of this section... selective reading perhaps?

anyways, This is actually for my Supra. Supra's deserve to have everything Overbuilt and Over-engineered, hence, 4AWG-8AWG fuel pump Rewiring.

Fuel pumps are rated @ 13.7 volts most of the time. So in order for you to even get the aftermarket fuel pump to operate at its specified level, youd need to upgrade the stock wiring, cuz i can guaran-damn-tee you that you arent getting a whole 13.7 volts at your pump. the MK3 supra has a resistor inline w/ the fuel electrical system. it actually DROPS the voltage to the pump. besides, when i start running ~500 RWHP, im gonna need all the fuel i can get. So if you have stock wiring, youll be better off doing a mod similar to this. its better to have too much that too little. at least if im rich, i wont melt a piston.

 

the permatex is a nice touch! much better than duct tape in every possible aspect

 

i really dont think it is the fuel pump wireing that sucks although when i was running my car on the dyno we had to wire a seperate battery up to the fuel pump just to keep it from leaning out with the 550cc it was pretty insain and a aeromotive pump would be alot better choice than a shitty walbro

 

trust me, factory fuel pump wiring sucks. At least from a performance stand point.

the amount of current able to be drawn thru a small wire is minimal compared to a fine, multistranded large cable. The electrons actually ride on teh SURFACE of the wire... so the more strands you have, the more surface area, and the more electron flux the wire can handle. a single solid wire that is the same size as 12 AWG will not handle as much current as a Finely, mulitistranded wire of the same guage. soo... the more strands, the more thickness, the more current capability.

stock 14ga wire w/ relays and resistors is not something i would try to wire a "High performance" fuel pump to.

hope that helps...

this would also explain why your aeromotive external was able to feed the 550's and keep you from leaning out after you hooked up another power source.

 

are you from earth?


we need to start a chris traing school lol

I know this i am just saying that the inconsistancy in the pulses that the stock pump are sent suck and it really needs a constant stream of power , the bigger wire is better but just doing that is a bandaid to the real set of problems the ecu and realys should not be in the way of desiding on how much power the pump gets , on/off switch is best or even a hobss switch so you can give a full source of power when under boost.

 

you knew that electrons ride on the surface of the conductor??? wow, first person i ever met besides a physics teacher or an electrical engineer who knew that.

all i need is to use the Stock fuel pump power feed wire to switch the Relay for the fuel pump and just run the power supply directly from the battery... so the ECU isnt being used to supply power, its just being used to trigger the Relay... and thats gonna act like the HObb's switch: On or Off... no inbetween or Sort-of on.
