Alan,
The sole job of any water injection system is to inject water, as long as it does that, it fulfills its duty.
No system is more or less superior than others as long as it does its job as designed. Like a car, you can spend 10K dollars or 50K dollars, it will all take you from A to B. You can have a car that will deliver four passengers comfortably or you can have a car that only holds two.
Most curent water injection systems are Shurflo or diaphragm-pump based due to its flow capacity and low cost - in the region of 3L per minute and costing less than 100 dollars. Add a oil heater nozzle, you have a water injection system instantly.
When we first started looking into making water injection systems, we have tried many pumps on the market including Shurflo, Pumptec, Flojet etc and positive diaplacement gear pump. They all shared one negative feature for us - size and weight. At the time of decision making, we opted for making our own light-weight and small-size piston pump. This is due to our racing customers demanded such a set-up. As you are well aware that "customer is always right" so we started designing the piston pump as our main component of pressurising the water.
We have also running into other technical problems in sensing the flow on other pumps due to its "mega-flow" capacity while we were only using a fraction of its rated output. A electro-magnetic piston pump such as ours, although low in delvery rate, it was more than adequate for our customers at the time. One advantage we have found by employing a piston pump is that the flowrate can easily be adjusted and monitored by varying the duration and frequencyof the pulses we send to the coil windings.
A bigger piston pump has been planned and designed but we decided to put it on hold due to the current market demanding a low-cost and high flow system. Until the market matures and demanding a system that has more "house-keeping" features in-build, we are not prepare to bring such a system out.
Please note that we too supply Shurflo type system to "high-flow" customers with all safety feartures incorporated but only a few requires such complexity. As the current market demands a high flow and low cost system, we are in no position to compete until one day customer's expectations switch to a more mature high-flow system that has accurate flow control and block-jet detection features.
It is strange to us that for anythings else, majority of the customers want the best component for their engine, but when it comes to selecting a water injection system, all their original intentions regarding the safety features just vanish into the thin air. We are pleased that there are a still a small number of loyal customers out there that appreciate our efforts and contributions and attempt in making a perfect water injection system.
