10113, 310cc injectors what fuel pressures will i expect
Posted by jamesman, Nov-25-01 11:31 AM
i'm gonna get 310 cc injectors, i have a hahn stage II and i was wondering if anyone's used this combo with an afc, and if so what idle fuel pressure and 9 psi fuel pressure and what afc settings are you using.
thanks

you might as well get 440cc's. I think they are the biggest injecters that the S-AFC can control. your beable to get, i think, at most 20psi on race gas with 440's. I saw a post where the guy runs 18psi with 440's. Maybe that was pushing it though, im not sure. also I dont think the stock GS-T's are that big and they can handle 20psi with stock fuel injecters

10115, stock 4g63 uses 450cc injectors

most guys upgrade to 550cc when installing the bigger turbos(20G etc)with a SAFC. I personally know of people running a rock solid 20psi(16g turbo), ugraded fuel pump(walbro/holley/supra etc) with stock ecu and no SAFC. This is on the 4g63 and they are still running rich.
I am personally thinking about running a 310cc injector with 10:1 fmu. This is without a SAFC.
What exact fuel pressure are you guys getting with 10 psi, stock injectors and a 12:1 fmu. Please also tell me if you did the fuel pump rewire with your walbro. This probably pertains to mostly Star kit owners.
Remember guys, I am just rolling around ideas in my head. This is the way I learn....LOL
