Aquamist Direct port nozzle install...
I plan on installing my HFS-5 kit from Aquamist on my Turbo S2000 this coming weekend. I plan on tapping the runners on the intake manifold for direct port injection and running one nozzle pre-turbine to increase the efficency of my 3076R turbo. I have 2 questions...
First off my kit included 3 different injector nozzles .8mm, .9mm. and 1.0mm. I plan on ordering the remaining ones I need asap. SO my question for you is roughly what size nozzles should I run in the runners and what size pre-turbine? I should be putting down roughly 550whp when the car is tuned at 21-25psi of boost pressure. I am running 1000cc injectors for fuel delivery. Any help you can give on the sizing of nozzles would be great so I can get them ordered ASAP.
Second question. My HFS-5 kit included 2 805-357N M8 to 1/8NPT Brass Jet adapters w/ blanking plugs. I planned on tapping the runners 1/8npt and using these adapters to install the jets, however I cannot find a place to order an 2 more of these adapters. Is that the best method of install? Tapping 1/8npt and using the adapters or should I tap the runners in M8 directly and forget about using the adapters? And finally where can one buy such adapters?
ANY and ALL answers will be greatly appreciated! Thanks in advance!!!

At WOT, full boost conditions most a/f ratio drops down to 10:1 to 10:5:1. The optimum (where an engine is most efficient) would be to have 12.5:1 So that's where the water injection plays its part.
3% water to fuel provides the heat-absorption capacity to reach that "magical" 12.5:1 a/f ratio. However because water injection is not perfect, 10 - 20% is the recommended range for injection
So if you have
1000cc x 4 injectors = 4000cc
4000cc x 0.20 = 800cc is the amount of water you would want to inject at maximum brake torque.
Contact Richard Lambert from Aquamist richard@aquamist.co.uk he can tell you where to get the parts you are looking for and what the nozzles equate to in terms of flow - or you can probably google the Aquamist nozzle flow values
Check out this thread - lots of info- you can spend days reading it!

Anybody else that has done the install know where to find these? Fperra ran the aquamist system on his ITB Turbo setup and used the adapters to mount the jets... I PMd him but haven't gotten a response yet. If anyone knows where to buy this part let me know...
Thanks

got in contact with Richard and he suggested .4mm nozzles on the intake manifold runners and to start out with .4mm pre-turbine and increase the size of that nozzle until there are no more benefits. just thought i would pass the info on so the next person can find it easier

Excellent
Richard Lambert is one of the most dedicated factory reps i've dealt with in the aftermarket world ! He's very helpful and gets back promptly.
Which vendor did he recommend for the adapters?
http://www.iaperformance.com/index.php?cPa...62_1463&&page=2
carries alot of the Aquamist parts .. saw the blanking plugs but not the adapters.. surely they can source them.
I have the Aquamist installed in my Subaru, not yet tuned but it's one of the nicer H20 inj systems.
.4mm sounds about right considering he recommended .5mm on the RB26 @8oowhp
Interesting use of .4mm pre-turbine - are you sure he said to inject water PRE-TURBINE? or did he mean pre-throtle body?
Usually you don't want to inject water before the Intercooler on a daily driver bcause of condensation in the IC core. Most applications are pre-throttle or in the runners as you are doing it.
Are you goin 50/50 water/meth?
I blend my own. I get $4/gallon methanol locally and use distilled water. Do the mix by weight -NOT volume
If you leave in a freezing area, the meth helps keep your water liquid

The nozzle is intended to be pre-turbine to help me stretch the efficiency of my 3076R... the reason we went with such a small jet is to help prevent pooling in the FMIC as you spoke of and therefore hopefully avoid any issues.
