Just received an AEM FPR for my turbo project and it comes w/ three orifice sizes (.10, .15 and .20). The .10 is installed by default.

Any suggestions as to which would be most appropriate for my setup. I have a walbro fuel pump, rc 750's, 70mm TB, stock fuel rail and will be running around 18 lbs of boost (expected hp ~420).

Thanks in advance,
JC

 

you said orifice








I have no idea brother, Jeff or Brian would be your best bet

 

Hey Rob, can you move this to FI? I accidentally posted it in the wrong forum.

 

ill try Gimmie a sec....

 

should be there now


good luck

 

Until you test it on a dyno and find problems you should leave the default one in.

 

Thanks Sideways. That's what i was thinking but figured i'd call on the experiences of others just in case.

 

I don't recall what size it was but I went w/ the biggest one after seeing that towards the top of the RPM band, my fuel pressure would start going down
