Im about to step into the world of WI after hearing some great things about it, seems well suited to rotarys.
Hoping to go for a setup like yours DuMaurier, injecting pre-compressor and post intercooler, having been toying with the idea of ditching intercooler completely but think i'll see how it goes first.
Are you running an aquamist system? Im thinking of going for the 2s, but do you think the pump will be able to support 2 jets or will I need another pump? im reading conflicting things so not sure as to the pumps capabilities
After doing the math its look like i'll be needing to inject a fair amount of water, between 252cc and 378cc/min. When injecting pre-compressor does a certain amount of the water get, for lack of better term, 'used up' allowing more water to be injected from the 2nd jet without the engine bogging down?
Sorry for all the questions, but like i said, im a newbie 
so far on the rex im running a power fc, downpipe de-cat and cat back, induction kit (heat shield needed :smile: ), and soon to have some 1200cc secondaries in there, with the boost set to 1 bar my IDC is hitting 96% so i need to get that down.
cheers

I missed this post. If you need quick answers, post it to the aquamist section first I always check it section first.
If you require a flow rate between 252 - 378cc/min you have two choices, either use the Aquamist pump with a priming pump - it will get you to 580cc/min.
Shurflo pump is the other choice, it wil not be easy to control as it flow so much water even the pump run very slowly. Ideally if you can run the Shurflo pump continuously- bypass the excess water into the tank via a pressure regulator - some Shurflo pump can internal by-pass in built. If you go that route, make sure that the Shurflo pump do bnot exceed 65C as the in-built thermal switch will switch the pump off. I have run the pump continuously and after an hour ot so under the sun, the pump switched off, need to disconnect the power and re-apply to get it restarted.
I have tried many time to intergrate the two systems together (aquamist and shurflo) but was unable to reliably detect a block nozzle condition - if this is not too important to you, I would go for the Shurflo and some Aquamist MF2 controller pulsing a HSV valve.
