I believe 1000 is 15 GPH which is = to an M15 nozzle. That would be huge.

People typically run M7 or M10 on this platform for your power level.

M12 would be max which is 760. Unless you plan on running only 100% methanol then you could go up in nozzle size but likely little to no benefit.

Too much water and you'll quench. Too much methanol and you might be over-fueling too.

here's a recent log of the 94 octane 50/50 meth map

currently have the meth starting at 9psi and fully spraying at 17.5psi with the big nozzle (1000cc)

downsized to 500cc nozzle 50/50 mix on my e60 tune ......

http://www.datazap.me/u/msport335/mh...og=0&data=4-22

how/will i benefit from a bigger nozzle (cm7 or cm10) or running a 70/30 mix if i'm already pushing 22psi & 14 deg timing ?
