    Looks just like a 50# Riva/Delphi style. But is it?....Please help, my engine begs you.

    Serial Number reads as follows. 0285 17113738-52

    I think they might be 50lb/hr Delphi

    Rated at 50lb/hr @ 43psi and 57lb/hr @ 58psi

    But that does not make them 60# injectors in my book.

    Please help.

    All injectors are rated @ 43psi.

    Those look to me like the Delphi injectors, regardless of the rating they are crap and should be discarded promptly (IMO). Anyone running these should be cautious as they are known to lock at pressures a little above stock pressure causing catastrophic engine failure. Just do a quick search on the topic and you'll get the picture.

    Learned that quickly.

    I am thinking that I should be able to replace them with anything siemens from 60#, 62# or 70# all rated at 43psi and when setting the RRFPR to 58psi they will be supplying somewhere between 70-80lb/hr, and so when adding 20-22pounds of boost I should be getting shit loads of fuel?
