I just wanted to be absolutely certain of something. Are you saying that at 80-100psi, that a 0.4 "C" would atomise better than an "A" because the finer nozzle needs more pressure to work correctly?
Most likely my next step will be moving a single nozzle post throttle body and running a weak meth mix. Hopefully this way the faster meth evaporation will give me better inlet coolling than I have now, and in conjunction with a better atomising bigger nozzle (if I read the above posts correctly) get more water into the cylinders.
If that gets things heading in the right direction then i'll look at committing the funds to direct port.
