Has anyone out there had any experience with injector atomization?  The
fuel injector drivers had resistors in series with the coils, and I
wonder if a lazy opening and closing rate could have caused poor
atomization.  Any input would be appreciated as I am baffled.  I am
happy with the power/manifold pressure, but pretty disgusted with the
fuel burn.  Heeelllppp!

There is some recent evidense that higher injection pressures and
shorter
pulses give better atomization and better BSFC's. What injection
pressure
are you running? PL

I used the stock Nippon Denso 550 cc. injectors.  I ran them at 54 psi
to keep the duty cycle down.  They would have been running a bit over 60
at full boost.
