Did a search but didnt find anything. Im sure it's been brought up before but want to know if this has been tried with any success.

Has anybody run an RRFPR in conjunction with an emanage or similar piggyback? If this could be tuned without TOO much difficulty, I figure it'd be pretty sweet, allowing you to run moderatly smallish ~330cc injectors with some moderate fuel pressures for bigger power.

Any info on this?

 

YES BGR has and made 250 whp with a td04 on it at 15 psi https://www.miataturbo.net/forums/sh...newpost&t=4866

 

Most of the higher-boost EMB users around here are using AFPRs of some kind in conjunction with their units, since "moderatly smallish" injectors seem to be the practical limit of what a Miata with an EMB can handle.

(That being said, I can think of two people who are now going to jump on me and say something to the effect of "I'm running 550cc injectors on my stock ECU with no AFPR at 15PSI of boost.")

With the EMU this is all unnecessary as you can run the bigger injectors without problems. With 440's on my 1.6, I typically max out at about 70-75% duty cycle, and yet the car idles perfectly and passes the CA tailpipe test. Typical max bost for my engine is 11-13 PSI, depending on how the MBC is feeling that day.
