switching fuel pressure regulator

[garry goodall]

Hi guys,

my regulator is buzzing quite badly but only does it around 0-2psi boost, took it apart and checked for anything out of the ordinary and put it back together and it cured it for 10miles before it started again lol

i have just brought a sard regulator and was wondering if i switched it for the FSE one thats on the car and got the base fuel pressure setup the same (3.1bar) will it will be ok to run and will the gain be the same when on boost?

or will i have to take it to the dyno to get it checked for AFR?

cars setup to run 0.9 bar with supporting mods

cheers,

Probably overfuelling at that pressure at that boost. You would be fine with an fse set the same as long as its a 1:1 ratio.
hows your fuel pump? Is the sard regulator genuine or fake?

mmm only had the car a month, its the FSE thats on the car at the moment 1:1 ratio I believe, fuel pump wise I think its uprated walboro but no 100% sure, the Sard one I have brought is a genuine one.
