Fuel Pressure Dropping!! Help.
Pretty simple setup----
DOHC ZC Head :
Port & polished Head By Huy Tran Of Inline Racing
Supertech Valve Train
Stock Cams
Stock valves
DOHC ZC Block:
75.5mm 9:1:1 Compression Supertech Pistons
Balanced Eagle Rods
Polished and Balanced Crank
Line Hone Griddle
HKS Head Gasket
Stock Sleeves
Transmission
CRX Si Tranny
OBX LSD
Ram slipper clutch
Stock Axles
Induction
Td06 17c turbo with a 10cm2 exhaust side
Stainless Log manifold Fabbed by Inline Racing
2.5 Piping Fabbed by Inline Racing
38mm Tial Wastegate
Greddy Type S BOV
680cc Injectors
Aem Regulator
Drag Intercooler
255 Walboro pump wired to a 14v
Tuned on Crome Pro
Car was on 111 Tracktek leaded fuel and was on 23lbs of boost. The tuner and I decided to leave the car at 23lbs because the fuel pressure was dropping at 7k. Went from 48lbs of pressure to 62lbs of pressure and back to 50lbs. I used 16 guage wire to rewire the pump, could using this small wiring cause my pressure to drop like that? I was told that I needed to use atleast 12 guage for rewiring the pump to a battery. The pump is directly wired to the battery and fuel filter is brand new so im kinda stomped on why the pressure is dropping. Could it be the 680cc injectors maxing out? Any sugguestions???
