boost issues due to fuel regulators

[alanssaab]

ok ,i'll do this in engelsk my car ,a 88 900 t16s is running with a 9 k cooler+rrfpra full jt zorst system + downpipe a bigger turbo and a dawes device .
i blew an amm a few weeks back but got a second hand one which is good
i took my car to the previous owner for a tune up and he made another adjustment to the rrfpr
ever since the low boost levels are suffering
i fitted my 3 bar fpr and low rev boost is good but losing top end
the previous owner was wondering what fuel pressures other tuned 900s were running at ?
i gave him the keys a month or so back so we went a blast , he was very impressed , snaking in 3rd gear
any thoughts
i only wish my danish was good enough to post .the book i have is crap . lol

Hey Alan

It's okay that your danish is bad, you will learn... but when you use slang english it can be tough to understand for us, that have the crap english book !!! lol...

I dont understand what "dawes devise" is ???

I fittet a progressive fuel boost regulator to my og900 aero, and it was okay for a long time.
Then I had a problem with it because it was leaking when iddling. I took it apart and grinddet the surface off the valves and put it together again and that was it. It is woorking perfectly now.
Perhaps that is your problem too..

dawes devise: Er en mbc. En rigtig god bleeder ventil.
Det som Alan også spørger om, er hvordan det virker med både en 3.0 og rrfpr trykregulator. Jeg kan ikke huske hvordan Daniel i Silkeborg har sat hans op, Henrik Solgaard har lavet det samme. Er der nogle som kan huske det?

Og for den der ikke ved det, så er en "rrfpr" = rising rate, fuelpressure regulator, altså en progressiv brændstofregulator.
