ok well here is my spill...here's what i got

i have a v2-sq w/ aftercooler @ 12 lbs
75mm tb/plenum, afm pipe, x pipe, and 3.125 pulley, t56 transmission
with built bottom end....i'm probably looking somewhere in the 410-420 range (hopefully)...do you think 38 lb injectors with a 255 pump and kb bap will suffice?
what is the hp rating on 38 lb injectors? i really don't ahve the money to get 42s but if i have to i will find a way

Im getting tuned Tuesday so what do you think i will put down to the ground??

u might get by on 38's but i think it will be close, ur probably gonna need some 42's. u should have plenty of fuel pump though i would think. so u did go ahead and get that forged motor? did urs finally give up on u or did u get all that sorted out?

well i talked to my tuner and he said that 38s can be increased if you increase fuel pressure @ WOT....that comes from james @ RWTD...he said i will have enough presently but if i ever exceed the 450 mark i'll need to step it up...i also have a kb bap...fyi

in the 39s in the cobras are good till about 500 so i dont think you should have a problem with the 38s
