Default Injector placement

flow @ 43.5 psi/3bar

injector# / lbs/hr / cc/min / 80% duty cycle (7000rpms @ 14ms)

5 / 45.62 / 479 / 379 cc/min
7 / 45.62 / 479 / 378 cc/min
12 / 45.71 / 480 / 380 cc/min
16 / 45.71 / 480 / 379 cc/min
19 / 45.71 / 480 / 380 cc/min
24 / 45.62 / 479 / 379 cc/min
25 / 45.43 / 477 / 379 cc/min
28 / 45.52 / 479 / 380 cc/min

question is does it matter where I install a particular injector? if so then where and please explain why. I just want to know if I can inprove combustion and understand why injector is best install in what cylinder#. also I am upgrading my stock fuel pump, new pump is some where in the garage. not sure what fuel pump i have cause I bought it almost two years ago and dont remember what brand/psi . can I match injectors to cylinder or do I need to know what psi fuel pump I have and calculate in order to correctly match my injectors to cylinders? any help will be appreciated,,

Thank

They are typically installed from smallest to largest on an LS1 motor in a front to rear fashion... the rear cylinders run the leanest so the largest should be put in the rear.

Your flows are very close to each other (well matched) & have a negligible difference.
