Some Injector Help

I am bored at work, came across this, since their is always a big deal about what size injectors need to be ran, come with, bla bla bla.

basically take.........

(estimated power X .50) / (amount of injectors X .80)


so, using the 3.4l figures (my engine swap )

(160 X .50) / (6 X .80) = 16.66 lbs

Hope this helps!!!

TY, so basically the 3.1l needs 15lb injectors. Hum, maybe my 19lb's would be a bit much??

I think you could get away with it. Consider this -- I believe the 2.8's injectors are rated at 16 lbs/hr. Even if everything was the same as a 3.1, our injectors would be too big.
