It wouldnt suprise me if 1 was fine.

 

Would it not be worth finding out at mapping stage?

 

Failing that, what do the yanks do? would it not be worth shipping something over?

 

 

If i come to mapping and i dont have enough fuel again im gonna be mighty pi$$ed with myself, its a day wasted for myself and Ryan for the sake of a bit of research.

 

Most the yanks run twin/tripple intank walbros from what ive seen.

Why not run a built fuel system from PHR or Boostlogic? Michel did mine which is:-

 

-8an lines

Fuel cell modification

2 x Walbro fuel pump

Aeromotive FPR

Aeromotive -10 high pressure filter

Relays

Boost Logic fuel rail

880cc injectors

Custom Injector clips

Fuel rail connectors / fittings

-8an pertek fuel lines 19 meters

 

Ryan said when mapping it that there was loads and loads of head room with my little T61. I might be wrong but I'm sure he said it was only running 60% Duty cycle at 1.4bar. Although the twin pumps are quite noisy.

I have a full 1000cc high imp fuel system sorted now, just looking into pump options.

I am expecting a single swirl pot fed 044 to support my 600 BHP Skyline engine, but won't be 100% surprised if it's getting marginal. Talk of "how much BHP" is pretty pointless, flow is flow, and fuel consumption is fuel consumption. You can have 2 different engines making a genuine 600 BHP, but their fuel demands can differ wildly. Cams, mapping, BMEP basically. Some engine make 600 BHP far more efficiently than others! Making sure the big Bosch pumps don't suffer with voltage drop is very important to get the best from them, they have hefty current draw.

How about bumping up the fuel pump voltage, I havent been able to find any info on how the 044 flows at 18v.

 

MSD, Aeromotive and Boost-A-Pump all do controllers to increase fuel pump voltage.

Minimum Current: 12 Volts

Operating Pressure: 72.5 PSI (5 Bar)

Minimum Flow @ Outlet: 80 GPH (300 LPH)

Fuel Pump Location: In-Line

High Temperature Reduction: 8 GPH (30 LPH)

Weight: 1030 Grams (2.27 Pounds)

 

Fuel Pump Connections:

Inlet: M18 x 1.5
