680 cc injectors.....enough?

[slowblacktalon]

I have a t3/t4 hybrid turbo with a 60 trim compressor .70 ar and .63 ar exhaust side. FMIC, SAFC, 255lph pump and arp head studs and rod bolts. Now if I want to run 25 psi for example.....will that be enough fuel without running the injectors to max duty cycle? Can someone give me an example of their turbo, psi they are running, fuel management, and injector size?

In your profile, it says you have 720s. Are you downgrading or is that incorrect?

According to RRE's website 660's should be enough for 24-26 psi. Being a 1st gen with a 2g mas, though you should be able to tune 720's even with just an afc. If you are worried about running out of fuel, go with the next size up. Price should be the same or close.

I sold the 720cc injectors. I needed some quick cash and I had some RC 550's still. Now those are in my car and I have the boost turned down for now. I can get 780's or 680's for the same price. Should I go with the bigger ones?

680's are fine.
