What size injectors do you run? POLL
What size injectors are you running, why, and any test data to prove it is what your Car needs,
I run 30# with my 230/230 cammed 396.

Ford 24#.
I am not a fan of huge injectors... they sound impressive, but lets think like this:
A car has 30# injectors, and to make them work right, the pressure is low and the computer adjusted accordingly. Duty cycle? Rather low, maybe 60%?
However, if I use 24# injectors, crank up the pressure, which improves the misting property of the injector and the computer adjusted accordingly, my guess is that the car will actually run better. I am guessing, all things being equal, these injectors would run at 75%... either way, well below the 100% limit!
The only time a huge injector is needed is when forced induction or NOS is used...
oh, and crossfires don't count.

36# FMS injectors ($200 ebay), Because that is what my tuner was comfortable with and they where cheaper then the 42's. A good tuner can use a wide range of injectors. I am at 42 PSI FP and spot on A/F acording to the wide band.
