38389, What Size Fuel Injectors?????
Posted by lonnie1977, Jan-31-03 02:22 PM
What size fuel injectors do you guys recommend for use with my Hahn stage II. I believe I remeber reading about the Accell 30# being the ones to use. Will I also need a SAFC to correct my idle? How much pressure should I run with larger injectors at idle and full bost?

I believe the biggest injector we can use w\o using some type of controller (SAFC, etc...) are 310's or 30 lbs. I'm not so sure what the static and boost fuel pressure you should be seeing though.

720cc....Thats the shit i use, your car will idle like shit but it will have more then enough fuel or u can go with 550, that would probalby be perfect for your kit......later

550's perfect for a stage 2? I don't think so. Stage 2 you are best of with 30# and you can get those to idle very well.

x( 235cc Stock injectors and piston ring lands don't mix. :nono

:o 250cc(24lb) for stock replacements. Waste of time, but bare minimum.

:9 315cc(30lb) if you have an SFMU or HRC FPR.

:7 440cc(42lb) if you have an S-AFC too.

}( Anything higher than that is going to need either good electronic management or um... luck.

:+ I'll post this in braille next week.
