Best Surge Tank Capacity & Fuel Filters

[Shaun]

Hello,

I was hoping some of you could help answer some fuel system questions that i have in regards to my unfinneshed project.

Im feeding a fairly modified single turboed RB26 engine with a Walbro in tank pump and a single 044 external pump. The 044 will obviously draw from a surge tank that ill install, but which capacity will best suit my application. I can get 1.5 and 2.5 litre tanks, but which one? My turbo will support 700hp, so i suppose thats a guide as to the limits of the fuel system.

Also, i bought an Earls 'in line' fuel filter with a sintered bronze element the other day, but a trusted mechanic friend said that in his experience these particular filters will pose a restriction to fuel systems like mine, and in retrospect, it does look extremely small! For those people out there with high HP engines, id like to know what fuel filters you are using. Its easy to get an SX or Magnaflow filter with -8 fittings (thats the size i need), but i dont want to spend $210 + fittings for a filter that will support 1500HP! Surely there is something in between that will suit my application. Does anyone know of cheaper filters that wont restrict flow but will perform their job well? It will go in line after the Bosch pump.

Thats it thanks,

Shaun.

Well to start with....only use the 2.5L surge tank. 1.5 litres is too small for what you want and you would drain it too quickly.

For fuel filters, you should use something like an SX fuel filter or try the Vortech. The SX goes for $50 and the Vortech for around $160.

The SX fuel filter should be good for anything up to about 2000hp and has almost no pressure drop (0.1psi) for flow rates over 400L/hr. Need I say more?

Ring (08) 8582 3499 for details on how you can get one. That is in SA.

I'm sure they are available in Brisbane....it's just a matter of looking.

Out of curiosity can I ask why you would not use some type of filter before the main fuel pump?

As I understand and have witnessed, foreign matter is a major killer of fuel pumps. And having a maximum effort engine last thing you want is a pump failing.

044 will not be upto a true 700hp sorry.

Sard have a real nice surge tank setup with built in pumps,you can get a single pump or twin tank and their very tidy and super quiet.

The intank pump sucks through a filter (as standard), so this will remove any debris before the 044.

Also, im being a bit optimistic about the 700HP thing, so im sure the 044 will suit my needs.

Thanks for the info, but did you mean to write the SX goes for $150 (not $50)? Ill ring em on Monday.

A guy over at performanceforums has a 450rwkw toyota crown GT42 i think maybe bigger. (Lifting the head of the block at the moment) (Stock standard engine too)

And he is running a single 044.

So for your application on a 700hp turbo, it should do easy.

The 044 is a mother of a pump, that some people underate.

I have several customers in GTRs using this setup

- 2.5L Surge Tank, some with twin or single pump outlets

- 044 pumps

- Magnafuel 2 port Reg
