i'd just as well skip the 28#'s and go for the 30#'s (36# on ls1 FP).

you mean the 30# svo injectors run at 36#s when used at the ls1 fuel pressure levels? what kind of calculation did u do to come up with that jrp? cuz there are other svo injectors that i would like to know what they really flow at if this is the case. otherwise slap upside the head and tell me which way is up.

yes, the svo 30#ers run @ 36#'s when used on the ls1 FP. ford rates them @ ~43psi (IIRC) and the ls1 runs @ 58psi
