As above I'm changing spec I take it the fuel system is on its knees at this power
What needs changing , lines pumps etc

 

I just have a 044 pump and a new fuel pump loom

Steve

 

I have as above on 468bhp

 

044 pump, good condition wiring and hosing, and big enough injectors.
And that's about it.

Cheers Paul

 

For a bit more safety go for the dw350il.

I've got a facet red top lift pump feeding a 1.5ltr swirl pot and 044 fuel pump. That pump that Mark mentions may be a good option for me. I wonder if I'd have to upgrade lift pump?

 

Yes if you look up the specs on the facet they cant cope and only work due to the return filling the swirl pot.
I changed to a holley blue pump which was quieter in operation and greater flow rates.

Thanks Paul, that's another thing I`ll be buying then. I wonder if that`s why I melted a piston!?

 

Or you could just go OTT ,,LOL

 

Are you monitoring fuel temp on that as that's a lot of heat going in to that fuel.

Mark

 

mark the fuel won't get hot,it only drives on and off the trailer

 

I spy a little cooler on the strut brace, that is a bonkers setup lol

 

I think you will find that's the rear diff cooler.

The pump you require depends on the boost you run. At 2.5bar your pump will need to be efficient at 2.5 + 3.5 bar = 87psi. Most are out of puff at this. Also the fuel you use is mega important the bsfc of pump is .6 change to Methanol & its 1.2 meaning twice the fuel needs to be pumped Race Fuel is around .9 meaning 50% more required. This is a subject I have studied. I was going to write a tech article on Pump/Injector choice at high boost its very interesting.
