Water injection etc help an idiot?

[rx7veilside]

getting mine fitted wed shd be able to up the boost a bit then 1.1 at first see how it goes then 1.2 hopefully

I have made a full WI kit for around about £50 all in, I got most of the bits from the scrappy. The other bits I got from ERL i.e. the 100micron filter and atomising jet. The kit worked really well and made the car so much smoother on boost; however I don\'t think I\'d risk using such a cheap method on an expensive rotary engine, as a 5 gtt is a lot cheaper to rebuild if it did go worng

Now from the experience I gained from the WI kit I made, i would definitely want some kind of flow warning/sensor just incase a jet got blocked, water ran out or pump failed. I am tempted to make a kit for our FD trackcar, but this time I would definitely use a "proper" pump although I\'d probably use a very similar kit for the rest of it. Just time is stopping me at the moment as I don\'t even know if the engine runs yet! :rolleyes:

My new site should be up in next couple of days, as the company Im leaving are determind to cause the max disruption, but when its working you will be able to see the whole Aquamist range.
System 1
This starter kit will enable you to enter the exciting world of water injection: a high-power magnetic piston pump and a specially-designed atomising jet form the basis of this rugged system 1. The water-pump is activated when an adjustable pressure switch, fitted to the inlet manifold, reaches its preset point: delivery rate can be altered by changing water-jet sizes.
£380 inc vat
System 2c
This newly developed system is designed solely for users equipped with their own ECU so he can program his own water injection map. This system is being used by two top works WRC teams in the 1999 World Rally Championship. The system provides a pre-pressurised water line up to 8 bars and the flow rate is metered by our latest High speed Valve (HSV). The inline valve is made of high grade Stainless steel and capable of achieving a cycling rate of over 250Hz.
£494 inc vat
System 2d
For those who wants a 3-D water injection MAP but do not want to spend the time-consuming task of mapping, this system is perfect for you.
The heart of the system is a newly developed controller that reads the PWM signal from the engine\'s fuel injector (including Peak and Hold type) and convert it to drive the High Speed Valve to deliver water, it draws less than 10ma from the pulsed line. This will enable the water injection to follow a fixed water/fuel ratio.
A 3-30psi Adjustable Pressure Switch (normally closed) sets the cut-in point relative to the manifold pressure. It just cannot be simpler for the user.
The system provides a pre-pressurised water line up to 8 bars and the flow rate is metered by our High speed Valve (HSV). This inline valve is made of high grade Stainless steel. As usual, except for the water tank, the system is supplied with everything needed to be fitted with ease.
£556.00 inc vat
System 2e
An advanced version of the system 2d. Allowing the user to adjust the water flow from the dashboard. There is also provision for those using 2d, 2c &1s to upgrade to the 2e system. Not available for sale until approx March 2005.
£ still waiting.
System 2s
This is the ultimate water injection system: its function is directly comparable to a standard car\'s fuel injection system, except it controls water-flow. In addition, it has diagnostic circuitry designed to detect blocked water-jets and cut pipes. A special output link from the ECU can inform other systems in the event of a fault condition, so boost-pressure can be lowered to minimise engine damage. A pre-pressurized system enables instant response on demand.

they also have some great dash dispalys.
