M10 nozzle equals 630 CC/Min

two M10 nozzles work perfectly at 400+ hp if you are using 100% meth. they are way too much for water. if you choose to use water i suggest you disable one of your nozzles.

due to the properties of water you will not see significant cooling in the intake tract. water cools in the combustion chamber so your better gauge would be EGTs.

good luck and thanks for sharing. keep us updated,
