fuel pressure regulator modification

[timucin]

part number i received about bosch motorsport regulator is not working,i mean the regulator is experimental stuff still..

while i was talking to german tuners before they were saying something about modifying the rs2 regulator?!?
does anybody know what exactly is done to modify rs2 regulator for 5 bar?


thnx

Press the top if it down in a vice while measuring the change - if you use an air line just make sure the difference is whatever in bar from the original to 5 bar - as air will measure differently to liquid

Timucin,

I'm suprised that you were told that you could not get the 5 bar pressure regulator, I got mine (part # B280 550 113) from here , I was told that this was a motorsport part at the time, but was still able to get it. This was a year ago now....so maybe something has changed .
If you dont fancy doing the vice mod, it might be worth asking some of the big tuners, Dahlback e.t.c. if they can get you one.

You would need to check it fits our cars first

LOL,

I must have got very lucky last year then, nice to know I have a very rare part .

Seriously though it might be worth finding out if it still can be got from the place I got mine from.

We can supply a racing adjustable fuel pressure reg which will control pressure up to 8 bar max, it does not have pressure adjustment for vacuum or boost so is designed for systems where ecu controls all fuelling requirements and this regulator will maintain a constant high pressure in the fuel rail.

---is that description ok for my car?
