Standard 172 Fuel Pressure?

[Nickharding]

Hi Guys,

Trying to work out if i am going to need an External Fuel Pressure Reg or not.
Building a R5 Gtt C1J lump but with fuel injection, and obviously its turno charged.
Want to run 3bar standard, so hoping the standard pump and the reg is rated to 3bar?

Could someone tell me what the reg on the standard 172 pump is rated to please?

As if it is 3 bar, hoping i can just fit the 172 pump+reg to my tank, therefor i wont have to buy an external FPR, or run a return line to my tank.

Thanks.

Pretty sure its 3-4 bar. Im unsure of an exact figure though.

 

[Nickharding]

Thanks for your input mate. Hoping for it to be 3bar.

Anyone else?

not just pressure but flow that you want to worry about. mine seems ok on the sc clio but as far as im aware its only 80ltrs and hour, ill be swapping in for a bosch 044 soon

 

[Nickharding]

Sorry Fred, was meant to right it down but forgot! cant remember what you said!

 

[Fred@BTM]

3 bar give or take

the stock pump is "safe" upto 250-260bhp

 

[Nickharding]

Flow of what? i take it your talking about injecters? i will be using bosch 802's (Renault21 Turbo items), will flow plenty, only going to run about 200bhp.

 

[Nickharding]

So i dont have to change anything? can just use my pump and my FPR? and just run the the single line into 1 end of my rail and cap the other?
Like i said, aim to run about 200bhp with this engine, maybe 220 max.

don't need a FPR as its in the tank

edit - ooh its boosted, forgot about that!

Thats what i mean haha, Whats my options Fred?
Also, any news on the diagrams?

Edit: Dont matter if its boosted or not... aslong as there is always 3bar in the rail, it would be fine?

need any bits for it? ive a small collection in me shed, stage 2 turbo technics turbo, gearbox, head, pipes you name it i prob got it. you using volvo parts to convert it?

 

[Nickharding]

What you mean? to convert it? im using a 172 plenum and throttle body, making the lower half of the manifold myself, using a valver ECU with a different EPROM chip with my map on it to run it.
i think your on about a different engine?
