Evoms provided me a 5.0 bar fuel regulator but has the 4.0 crossed off with a marker and written on it 5.0 . Just wondering if this is normal ?

here is mine. look similar to you? not sure as i dont recognize that mark

 

does a 5 BAR FPR require a reflash? I assume upping the fuel pressure will up the flow in all conditions?

Injectors are just nozzles that open and close for a certain period at a time.

 

I would say yes, but there is no need to change the FPR if you are not changing the turbos. When you change the turbos, you need to change your fuel, which then needs new mapping and hopefully the power makes you change your underoos.

 

i got mine directly from neuspeed and it looked like the one Dan posted a pic of.. I freaked out at first coz it was some silly sticker on it and underneath had a 4.2 on it i think it was....but the sticker was 5 bar!!! I was re assured and I installed it! NO PROBLEMO!!!!!! worked out just fine....just a royal pain to get at.... you wont be done in 20 minutes i tell ya!!! But can be done!!

 

id b careful installing it if you have no need for it......

 

why not call them and ask? I''m sure they will respond in a timely manner.

 

evoms just crushed a 4.0 bar to make it a 5 bar IT IS NOT A TRUE 5 BAR FPR. Order a real one form board sponsor STRATMOSPHERE. I do not trust a crushed 4 bar. IMO

Agreed. Crushed 5 bars and real 5 bars react slightly different.

 

what exaclty is the diff in reaction? vac?

 

Spring seat pressure vs travel. This will create a fuel pressure curve that is has a different boost reference.

 

To clarify more, they both with produce 5 bar with out any vac source...the difference is how they react with vac or boost reference.

 

I have the 5.0 fpr on the shelf like HighHats suggests. If you have questions on the install, my techs can explain, not a difficult job.

 

how much did you pay for it?

 

Buy Bosch FPR only, motorsport part number B 280 550 113/2, they usually run about $200.
