What pressure on AFPR will flow 24# injectors like stock?

12-18-2003, 03:43 PM

What pressure setting on my AFPR will allow 24# injectors to flow similar to the 17# stock injectors?

The reason i'm asking is that my FPR crapped out and i figured i'd replace it with an adjustable one in anticipation of future mods (heads, cam, exhaust, etc). I got to thinking and want to get the LS1 injectors off of SLP for 99.99, but they are 24# injectors and would be too much for my ECM without an AFPR.

My slide rule says 21-24 lbs of pressure at the fuel rail for 160 crank hp. Have a moderator check this because I got my slide rule from a dumpster near white sands, and it glows when I hold it close to my monitor.

2001 Kroger\'s shopping cart MODS- * disabled locking wheel * used Flowmaster and some LS1 parts ... I think there\'s an old Bilstein shock in there too.
