CSR fuel pressure

[weeman]

......as in the title, does anyone know what the fuel pressure should be in a 2.3 Duratec.

My searches so far make me think it should be 3 Bar but I've not found a definitive answer.

Thanks in advance.

Martin,

 

My car has a CSR260 engine from Cosworth, and they told me 4.2 bar (61psi) 4.3 bar (62psi) fuel pressure required.

Thanks Sean.

I did have a look on the CSR forum before posting this thread but for some reason wasn't 100% sure about what I was reading.

3 bar seems a popularly held opinion while Cosworth say 4.3 bar. 'Go figure' as they say in your neck of the woods

Hi again Martin,

 

I found another source, which I had copied into text in the event the URL might some day be changed (luckily, as it had changed). Copied and pasted below, including the currently inaccurate URL:

Minister Engine Data pages

 

Optimum Engine Working Parameters for Cosworth CSR260 Duratec

 

http://www.minister-power.com/support/engine_data_pages/cat_csr260_data_page.htm

Oil Pressure 3000rpm 4.1 Bar/60 psi

Oil Pressure 5000rpm 4.8 Bar/70 psi

Oil Pressure 7500rpm 4.1 Bar/60 psi

 

Oil Temperature Maximum 100°C

Oil Temperature Minimum 50°C

Oil Grade / Viscosity 5w/50

Oil Filter Number (Purolator) L1763/PC603 (UFI 2311800, FIAAM FT4763, FRAM PH2874, MANN and HUMMEL W77, PUROLATOR PC603, TECHNOCAR R15)

 

Coolant Temperature

above 5000 rpm 75°C ± 5°C Track

85°C ± 5°C Road

Antifreeze / Inhibitor content minimum 50%

 

Fuel Pressure (Reving) 4.3 Bar ±0.2 Bar

Fuel Grade (Road) 95 RON

Fuel Grade (Track) 98 RON

Spark Plug Torque 12Nm

Spark Plug Type (NGK) BR7EFS

Spark Plug Gap 0.66mm /0.026"

 

Maximum Power at 7500 rpm

Maximum Torque at 6000 rpm

Rev Limiter set to 7700 rpm

Data Logging Parameters

Minimum rpm to Start Logging 3000 rpm

Set Shift Light to 7400 rpm

Set Low Oil Pressure Warning to 1.36 Bar/2 0 psi

Oil Temp. Warning (Max) 120°C

Maximum Coolant Temperature 95°C

Minimum Battery Voltage 11.0V

Maximum Battery Voltage 14.8V

Minimum Fuel Pressure 3.4 Bar/50 psi

 

It would appear that Cosworth USA, Cosworth UK, and Minister all agree on 4.3 bar. Not sure where 3 bar comes from, but whatever works.

and thanks also to you Geko.

You've both put me to shame with your research

Thanks Gerhard.

I'm a little surprised that all responses thus far have been from California and Austria!

Pressure is usually stamped on the fuel pressure reg which on the CSR dead end rail set up is nest to the fuel tank If I remember correctly.
