Do I need a restrictor??
Finally got the system up and running today and did a manual test with the jets installed in the intercooler pipe and there seems to be a LOT of water being sprayed in.
The engine is a Nissan RB30 which is running 6 x 750cc injectors and about 22psi of boost (might wind up to 25psi with water/meth). The car is making about 530hp at the flywheel currently. I plan on running a 50/50 water meth mixture. I've installed 2 x 1.0mm jets in the intercooler piping post intercooler. Do I also need to fit one of the restrictors which came with the kit? What I've worked out is: 750 x 6 = 4500 4500 x 20% = 900cc 1 x 1.0mm jet = 450cc @ 140psi (165psi - 25psi boost) Total of 900cc means I need to fit a 0.9mm restrictor in the FAV??

Re: Do I need a restrictor??
Does it run the system flat out when you activate it using the test jumper? Just that there was a fair volume of water sitting in the pipe after a pretty short amount of time(was disconnected from the engine to test the spray). Will the water atomise more with boost pressure running through the system?

Re: Do I need a restrictor??
The system should run flat put with test jumper.
Please explain the second question, I don't understand it fully.

Re: Do I need a restrictor??
I'm just looking through the manual again and the flow chart for selecting injector size is different to the one on the Howerton Engineering site. There is a fair amount of varience so I'm a little confused now. Seems like the 2 x 1.0mm jets are way too big. A 0.8mm and 0.9mm combined equal 898cc of flow
