#12972, "RE: How much boost with these mods..." In response to In response to 13
Never mind I was just trying to be lazy.... I found it lol
"Rewiring the fuel pump with a larger gauge wire can help the stock pump (or any aftermarket pump) maintain higher fuel pressure/volume throughout its' entire operating range, as the stock wire is pretty small. The small wire limits the voltage to the pump, and under high boost, the lower voltage can severely affect fuel output. Some people have measured 10 volts or less at the pump under high boost with the stock wiring. Adding a larger wire and relay to feed the pump can restore the voltage to that of the battery (usually 13-14V), maximizing pump output.
So, how do you do it? It's pretty simple - just add a larger gauge wire (anywhere from 12 to 8 gauge will help, the larger the better, though 10ga seems to work fine for most people) from the battery, and run it to a relay mounted near the pump. Then cut the stock 12V wire leading to the pump, and splice the relay inline."
I use to have a White 99 GS Sport with a Star Stage II Ball Bearing T3/T4 turbo...it was fun untill....well those who remember me know Oh Ya...this is what I have now... a 99' GSX...
