4 bar fuel pressure regulator

[djdougalno1]

dose the s3 come with a 4 bar fule presure reg as standard

 

[Dani_B19]

No 3 bar.

 

[Broken Byzan]

A4 1.8t's were 4 bar

 

[djdougalno1]

so will any 4 bar pressure reg fit or dose it have to be a vag one

 

[MintyS3]

Doesnt need to be fitted to an S3 with a k04 if your thinking about it.

I would of thought a fpr is an fpr...

I am sure that as long as they bosch units then all good, but they are all different pressures so be aware of that. 4 bar from Audi A4s and Passats from 1995 to 2001 ish

 

[marcyp]

im sure the fuel reg on my qts is a 4bar

I fitted a mk3 golf vr6 reg. its 4 bar and not too expensive.

 

[mattyboy199]

will it do anything though going 4bar ?

 

[Broken Byzan]

Not unless your tune calls for it !

No benefit just sticking one in randomly

As Mark says...not unless your map needs it.

I tested adding one when at the Dyno with my S3 and lost power due to running too rich.

 

[djdougalno1]

amd technik are goin to build a custom map when all the upgrades are done an they say it will need a 4 bar reg

I'm thinking of getting an mbc +diode mode.. But, I read that if I'm gonna add some psi I should fit a 4 bar fpr. Car is a S3 8L BAM. Does it comes with 3 bar or 4 bar?

3 baaaaa
