Question Do I need bigger injectors?

Here is what I am got on my 03 Z06 currently:

Kooks Long Tube Headers w/ high flow cats and xpipe
Vararam
160 tstat

Here is what I am getting ready to add:

Futral Motorsport F13 Cam 230/232 .595/.585 112+4
Patriot LS6 style 2.02"/1.6"/59cc Heads which will make compression 11:1

Stock block and everything else.

Thanks
Ray

its possible, i would think to run 80% u need something like a 36# injector with that setup. i went over kill on mine due to future mods i am planning and run 42# (48 at our pressure) fords and run them at 62%, i had 43 (37.8@ 3 bar)# on before and was running at about 65%-70%. i would think for 30# would be good. i have the same cam and afr heads but only 10:1 CR

Some quick math:

450 rwhp is around 525 bhp

(525 bhp x .50) / (8 x .80) = 41 lbs/hr injectors

I think you should go with a set of 42s...I've heard they are pretty easy to tune as well.

42's should work real nice with your setup.
