4Bar FPR

[kohmikey]

Hi Guys,

What does a 4bar Fpr do. I know it is a fuel pressure regulator but just not clear on what it actually does.
I was looking at getting Revo stage 2 and i already have a recirc valve, green panel filter and have just ordered my turbo back Milltek system. So do i need a 4bar fpr like people suggest before i get stage 2?

Thanks

Mikey

Yes, its a requirement of stage 2......

A fuel pressure regulator is a small device with a diaphragm inside that maintains a constant pressure (or tries to) regardless of the rate of flow. Basically you can put any fuel pressure in, and get a constant "set" pressure out - however much the input pressure might vary. So a Fuel injected car for example has a pump that might run at anything between 150psi static, and 50psi under flow conditions in use. This is "regulated" by your fuel pressure regulator to (usually) 45psi constant (3 bar).

Thanks Andy. So there is a chance that i may even get better fuel consumption or does it not work like that?

 

[andythom]

it is possible mate yeah.....

but with more power you'll prob find you right foot will be heavier

 

[kohmikey]

Yeah i think you are right, but with better mpg my foot will be heavier for longer
Thanks for your help.

I thought that if you got Revo Stage 2 and 4bar... you needed a KO3s... or is that just on Mk3's??

 

[andythom]

mk4 1.8 20vt is ko3's standard

 

[seli_babe]

mk4 1.8 20vt is ko3's standard

Oh right OK.. thanks didn't know that

I have just thought, so everytime i turn off the revo stage 2 using my sps i will have to remove the 4barfpr and then vice versa when putting it back on again? How easy is it to do?

pull a pin out the pull the fpr out but only put the new one in just before you get stage two dont do much driving and drive carfully as its not suposed to work with the 4bar on stage 1!
