rx7 setup

[sdminus]

Your inj duty must be pretty high at the mo.
I would put the jet just downstream of the throttle body. Eg near the top of the elbow to get even atomisation over the two secondary runners.

I would get the amounts of water small if you only wanna effect the charge temps. In your case less will be more.
Who is going to map it for you ?
I would say that the amount you inject will depend on the temp of the air its to be injected into. What is you average charge temps ?

you are currently flowing 821 CFM or there abouts with 44gph @100%idc guessing at about 1.10 -1.20 bar @ 10.8 afr
From my logic i think you are going to need a jet capable of flowing about 3 GPH to get near full atomistaion ( too aid cooling without adjusting fueling )

There is a jet comparison on here somewhere or some nice person may translate for you.

how is MRC LOL
