Re: LT5 fuel pump?
Quote:
The least expensive pump(Edit least expensive high flow aftermarket pump) that I have found is this Racetronix pump for $100. Ive got a few American friends that use these. Picture Specs here. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx FEATURES: Flows 340 Liter/Hr (90 US GPH) @ 43 PSI @ 13.5V * In-tank use only / submersible design Reliable and quiet turbine impeller Can be used with EFI or carbureted applications May be used in pulse modulated systems (PWM) Center-inlet design. Same fitment as Walbro GSS340M, GSS307M and GSS294M pumps. Each pump individually tested For gasoline (use with E85 will reduce life expectancy) Integral check-valve Over-pressure safety bypass valve MECHANICAL SPECS: Weight: 355 grams / 0.783 lbs Diameter: 38mm / 1.54" O.D. Body: Black-plated steel with laser etching Inlet: 22mm / 0.866" OD (non-tapered) Outlet: 8mm / 0.315" (with barb) PRV Activation: 90PSI nominal Impeller design: Single-scroll hard-anodized aluminum turbine ELECTRICAL SPECS: Recommended operating voltage: 13.5 volts DC Minimum operating voltage: 6 volts DC Max operating voltage: 18 volts DC Current draw @ 43.5PSI: 12 amps (13.5VDC) Current draw @ 58.0PSI: 14 amps (13.5VDC) Current draw @ 80.0PSI: 17 amps (13.5VDC) NOTES: REQUIRES UPGRADED IN-TANK AND EXTERNAL WIRING FOR PROPER OPERATION. THIS PUMP IS SOLD WITHOUT ANY WIRING, FILTERS OR MOUNTS. SELECT THE PARTS YOU REQUIRE IN OUR WEB STORE BASED ON YOUR APPLICATION xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxx 340 lph at 43.5 psi, not bad for $100, so slightly less for the ZR-1's working fuel pressure of 50.75 psi(350kpa), which will read lower with the engine running as the FPR is vacuum referenced.. I just wonder at what point the stock lines and/or FPR's will become overworked. Anyone have a flow rate for the primary and secondary pumps of the ZR-1?
