Nozzles of 10 and 7 seem a bit much. I have to find time to do more logging, but anecdotally for me I felt that going from the size 7 to 10 made an impovement, going from 10 to 12 made an improvement, but that going to a single 14 did not yield much.

I would guess that a total (whether single or dual nozzle) between 12 and 14 gph is good for RB's and that spraying much more than that and you will be giving the engine too much added fueling to be beneficial for the hybrid turbo setup.

I'm sure someone else has real data and thoughts on what's the optimal meth flow for a set of RB's. Good luck on getting it up and running soon.
